Guide to Geocaching and GPS Photography Ver. 1.1

Guide to Geocaching and GPS Photography using GPS Tuner 5.0 by Turgan

I’ll try to create a simple guide on how to geotag your photos. This way you can

I am in no way an expert in any of these fields. Also English is my second language. Please excuse and alert me, on any errors I might have below.

Tools:

First we’re going to load a custom map (an actual geospatial image of the location) off the net to our GPS Tuner Map Calibrator on our desktop computer.
Then we’re going to calibrate and break this map into parts so Gpstuner can give us a high quality map covering a large area.
We are going to load these into our Pocket PC, preferable to our memory card.
Once in the pocket pc we’ll make sure our camera’s and our pocket pc’s time is synced. Then we are ready to start taking photos.
Once our trip is complete we’ll transfer the photos and the logs and if needed, convert them to a GPX format. (especially required for GpicSync)
Then we’ll use GPicSync or RoboGeo to tag the exif’s of our photos and generate google maps enabled photo gallery of our trip using either one of these software or the awesome Google Picasa.

Here we go

Part 1 – Getting our hiking map into pocket pc GPS Tuner

We are going to use geospatial images for our geocaching map.

It’s not easy to get tiles for anywhere we like, so we’re going to have to work our way to it.

Also

Warning: This one is a huge gray area. http://web.media.mit.edu/~nvawter/projects/googlemaps/index.html  It is semi-illegal to get these images without paying for them. These are all copyrighted images. I highly advise against saving them to your harddrive, printing them, and even using this guide to do your geocaching/gps photography.

Also don’t download mp3’s. As a matter of fact, try not to buy ipod’s because it is an incentive to download illegal mp3’s which fills up 80% of the ipods on the market today. Do support your favorite artists by linking to their purchasable songs from your pretentious neo-look-at-the-cool-mixtape-i-did mp3 blogs. Also don’t watch copyrighted illegal video’s on Youtube. If you see a copyrighted video on youtube, flag it and ask Google to remove them. Try to catch them on tv. A bit sarcastic here; but I’m serious.

 

Done with the warning. On to our piracy.

Super-Googer http://pallit.lhi.is/bigice/bigpic.html  Gives you the ability to display any location by simply pasting satellite map tiles code into this page. How do we find the code of a particular map tile?

By viewing the location we’ll be terkking at in Google maps. View the site you want to visit in Google maps and select the correct zoom level you want to maps in,

Example:

http://maps.google.com/maps?f=q&hl=en&q=garrison,+ny&ie=UTF8&ll=41.380979,-73.940649&spn=0.010481,0.020084&t=k&z=16&iwloc=addr&om=1

Now my starting point of the trip, thus my starting tile is the train station , so it’s somewhere around here:

google location

  In your Firefox, go to TOOLS > PAGE INFO and browse to the MEDIA tab. Once in media tab, you’re going to have to find the exact tile that this image represents. In this case, it’s this:

starting tile

“tqsqtstsstrrtstsq”

Each zoom level adds one letter to this code. Details are explained here. Be careful that this might not be the image of the exact zoom level you might be looking for. For example tqsqtstsstrr is from the same location as tqsqtstsstrrtstsq but 5 zoom levels up.

Anyhow, we paste this code into Super-Googer, change the Number of horizontal/vertical tiles as you like.

http://pallit.lhi.is/bigice/bigpic.html

This is our final trekking map that we’ll load into our pocket pc:

http://pallit.lhi.is/bigice/makeme.php?startPic=tqsqtstsstrrtstsq+&hTiles=15&vTiles=20

This page is made up of many small tiles, if you right click and choose Save as… it will only save one tile. Somehow we have to save them all as 1 image.

For this we need a great Firefox extension named Screen grab.

http://www.screengrab.org/

Once you installed Screengrab just fire it up by clicking on the status bar icon on the lower right corner of firefox and choose Save > Complete Page / Frame and save your map to a location.

(Notice: If your Number of horizontal/vertical tiles are HUGE, ie. 30 tiles x 30 tiles, you might have some memory problems)

Now that we saved our image, there’s only one adjustment to make before we calibrate this map and load it into our Pocket PC. Somehow the images saved with Screen Grab do not show the Pixels / Inch. Which I usually keep around 72 pixels / inch (GPS Tuner suggests 96dpi but their default map is 72 somehow). So I open this image up in Photoshop. Go to Image-Image Size, set the Resolution to 72 pixels / inch (even though it already shows so) and then save the image in MEDIUM quality format to the same location.

 

From GPS Tuner 5.0 Manual:
 When scanning maps for GPS Tuner, we suggest a 96 dpi resolution.
 For best results, keep map pixel size under 5000 x 5000 pixels.
 Keep file size under 20 MB (use higher compression if necessary).
 Although GPS Tuner supports the calibration of rotated maps, for best results we suggest to use North-oriented maps.

Now we load map calibrator and open our saved final map image.

http://www.gpstuner.com/download/index.html

In order to calibrate the map we’re going to use the page:

http://www.earthtools.org/

Go to Find Places on the main page, and type Garrison. Garrison in New York is somehow the 20th match. Click on the Zoom that’s right under Garrison – United States of America, New York

Switch to satellite view and zoom in further to find the train station in garrison. I’m going to use the corner of this overpass as a calibration point in Gps Tuner Map Calibrator. I drag the crosshair in the Earthtools maps to this corner, and click on LOCATION tab in Earthtools page on the upper left.

earthtools

it shows me what the coordinates are:

Latitude

41° 23′ 3" N

Longitude:

73° 56′ 47" W

And this is exactly why I type in GPS Tuner Map Calibrator. In map calibrator I click and hold on the corner of this exact location of overpass until the Add New.. > Calib Point pops up, and I type the above values in there. I make sure that N and W values are correct. If not you’ll have to click on the E in the popup ADD CALIBRATION DATA window in map calibrator to change it to W, so that you have 73° 56′ 47" W rather than 73° 56′ 47" E.

I repeat this step 2+ times for other locations on the map, so that I get a finely calibrated map.

Once this is done, I save this map in Map Calibrator by Save… > Save Multiscale Map Slices

Once they are saved on my harddrive, I transfer them to my pocket pc under my memory card, under a GARRISON directory.

Then, on my Pocket PC the only thing I have to do is click on the map screen map screenclick on Open map open map buttonbutton and select my map to load it into GPS Tuner.

PART 2 – The Trip, Recording our logs, optimizing Gps tuner tiles

If your GPS is working and positioned it will automatically center you on the map.

You have to make sure that GPS Tuner is recording logs. For this, under  click on the Manager Window icon managerwindow and start your NMEA and Tracklog logs.

gpstunermanual

Once you’re on the border of a map image slice, a new slice showing your current location should show up…if not take a look at here:

http://www.gpstuner.com/forum/viewtopic.php?p=5184&sid=a9d796b7b336a57b5b1bfdcd93df25c4

“You may increase the speed of the load time by:
If your maps on stored on SD card, move them to a folder on your PDA "Main Memory".
Reducing the file-size of the map-slices.
Reducing the resolution of the map-slices.
Increasing the number of map-slices…“

Or here:

http://www.gpstuner.com/forum/viewtopic.php?p=4889

“If you have an average hardware (average CPU speed, average RAM speed, average Card speed, etc), you would probably be well advised to load medium sized (1000×1000 pixel) pictures or smaller. The logic is that your hardware would need to access image slices less frequently, but the intitial tradeoff is that the loadtime for the image would be longer than, say – a 500×500 pixel image.

So here’s my theory: Make a map-slice based on the dimensions of your PDA screen (mine is 320×240), with the initial overlap set at half the larger number (320 for me). Then set your PDA overlap setting to half of that number (160 for me). This will follow the Developer’s logic (as show above), and only force the program to load those images of your map in whichever direction you might be travelling.”

 

SCREEN SIZES:

DELL X51v 640×480
Palm Tungsten T5 320×480
DELL AXIM X30 240×320
Treo 650 320×320

“I just set the overlap to 50px (as I had exported with 100px) and it works like a charm!!!! No problems whatsoever!

I still cannot believe the solution was that simple. And actually logical, Map Export counts the pixels on both sides as it calculates how much bigger to make the map (a 933 pixel map becomes 1033 pixels in total with 100 overlap) and GPS Tuner on the other hand needs to know when to start loading the next slice, which of course is half of that.”

Developer
Site Admin

“You sould use 120 pixel overlap in GPS Tuner if you have redered map with 240 in Map Calibrator. Unfortunately Map Calibrator is undocumented, so the only thing I could do it to set the default overlap 320 in MC and 160 in GPS Tuner and until users leave them it sould work.

So, please try to use 120 px.”

 

PART 3 – Transfering Photos and logs to computer to create GPS Photo Tour of our trip

We’re going to transfer the photos to our computer, encode the location of each photo to the exif header, and upload them online to view them on a map.

We have many options to do this:

  • GPS Visualiser
  • GPICSync
  • Robogeo
  • Google Picasa (this is a fantastic solution for these reasons: Easy to upload, the photos have a Next-Previous button in the google maps balloon, it works very fast, it accepts 500 photos and processes them faster than any solution, it also has an amazing "Play" feature which switches through each photo and gives you a google maps tour of your trip!)

Once our map is ready, our batteries are loaded we, we synchronize the time of our PDA with that of our camera and take our trip. Then all you have to do is transfer the files to the computer. This includes the images from the camera as well the tracklog (trk file) or the NMEA log from the pocket pc.

Whether your file is a tracklog or a NMEA file, it’s best if you convert it to GPX first.

You can upload the file and have it converted here:

http://www.gpsvisualizer.com/convert?output

Once your file is converted and saved,

Install GPICSYNC from the following location. Load your pictures directory and your GPX file to the program and follow instructions.

http://code.google.com/p/gpicsync/

OR

You can also try ROBOGEO.

http://www.robogeo.com/home/

I’m not going to go into the detail of these programs. In all of these programs all you have to provide is a GPX or a NMEA tracklog, and a directory for photos. These programs automatically match the images with the gps log and stamp the location data to the exif of the photos.

 

Next is using these programs to create a google map. Getting a google api key is necessary for some of these solutions.

 

Or Google Picasa:

Google came out with a new feature on 6/27/2007. Geocode your photos with one of the above three programs and your geocoded photos to Picasa. Your Geocoded photos will have a little cross-hair in the lower left corner of their thumbnail in picasa. As seen:picasa

 Result is here: http://picasaweb.google.com/turgan/FireIsland/photo#map

 

 

UPDATE 1.1 6/28/2008

Added Google Picasa solution above.

A Simple Song That Lives Beyond Timeby Eric Weisbard

Immediately after the suicide of Kurt Cobain, lead singer of the rock band Nirvana, last April, MTV broadcast almost continuously an hour-long "Unplugged" special that the band had recorded the previous fall. The final song on the program was unexpected: it was the only one not previously recorded by Nirvana or even written by an alternative rocker. Called "Where Did You Sleep Last Night," it had the cadences of an old ballad or blues tune and lyrics that Mr. Cobain’s deathly rasp made absolutely haunting.

In fact, the song was a folk song, usually known as "In the Pines," which dates back at least to the 1870’s. Its appearance in the repertory of a Seattle grunge singer is only the latest chapter in its complex history. (An album of Nirvana’s MTV concert, "Unplugged in New York," was recently released on the DGC label.) Those who have recorded the song include the folk legends Leadbelly, Joan Baez and Pete Seeger, the country pioneers Bill Monroe and Chet Atkins, the rockers Sir Douglas Quintet and Duane Eddy, the pop vocalist Connie Francis and the jazz saxophonist Clifford Jordan.

Even within alternative music, "In the Pines" has something of a history. Annette Zalinskas, formerly of the Bangles, recorded the song with her band Blood on the Saddle on 1986’s "Poison Love" album. Australia’s Triffids did a takeoff on "In the Pines." (The genre-crossing Beck used the phrase "in the pines" in doggerel he wrote for the booklet that accompanies his recent album "Mellow Gold.")

Researching the song for a 1970 dissertation, Judith McCulloh found 160 different versions, a finding that raises the question: Why does a song like "In the Pines" endure and permutate so insistently? The answer may be that its essence is not a specific story or even a musical style but the kind of intensely dark emotion that, as is the case with much in American music, survives longer in popular memory than does treacly sentiment.

The song probably has its origins in the Southern Appalachians, where it is still passed on as part of an oral tradition. The mystery writer Sharyn McCrumb says a college friend from Georgia taught her a verse that she used as a chapter heading in her 1992 novel, "The Hangman’s Beautiful Daughter." As she demonstrated in a telephone conversation, she can also sing a very different "Mitchell County, N.C." version that includes a reference to the local Clenchfield railroad line.

Dolly Parton, who performs a version on her recent album "Heartsongs" says: "The song has been handed down through many generations of my family. I don’t ever remember not hearing it and not singing it. Any time there were more than three or four songs to be sung, ‘In the Pines’ was one of them. It’s easy to play, easy to sing, great harmonies and very emotional. The perfect song for simple people."

In the 1981 book "Long Steel Rail: The Railroad in American Folksong," the music historian Norm Cohen notes that "In the Pines" has three frequent elements, not all of which always appear. There is the chorus "in the pines," a stanza about "the longest train I ever saw" and another verse in which someone is decapitated by a Train.

"The longest train" section probably began as a separate song, which merged with "In the Pines"; references in some renditions to "Joe Brown’s coal mine" and "the Georgia line" may date its origins to Joseph Emerson Brown, a former Georgia governor, who operated coal mines in the 1870’s. The earliest printed version was four lines and a melody compiled by Cecil Sharp in Kentucky in 1917. Another variant, mentioning the train accident, was recorded in 1925 by a folk collector onto cylinder, a precursor of the phonograph. The next year, commercial hillbilly recordings of "In the Pines" and "The Longest Train" began appearing.

How did Kurt Cobain discover "In the Pines"? Long before Nirvana’s rise, he and Mark Lanegan, leader of the Seattle rock group Screaming Trees, formed a friendship around a mutual love of Leadbelly. Mr. Lanegan owned a copy of the original Musicraft 78 rpm of "Where Did You Sleep Last Night" that Leadbelly recorded in 1944. "My father gave me the record when I was a kid," Mr. Lanegan says. "He was a schoolteacher, and he found in the attic of an old school a box of blues records." Mr. Lanegan and Mr. Cobain recorded an EP of Leadbelly tunes, but only "Where Did You Sleep" was released on Mr. Lanegan’s 1990 album, "The Winding Sheet," with Mr. Cobain playing guitar.

Although Leadbelly is credited with authorship of "Where Did You Sleep" on "The Winding Sheet" and Nirvana’s "Unplugged in New York," his own discovery of the song was almost as secondhand as that of the Seattle musicians. Alan Lomax, the folk music archivist and promoter, reported to Ms. McCulloh that Leadbelly learned parts of the song from someone who had taken it from the 1917 Sharp version and other parts from the 1925 cylinder recording.

For all its complicated history, the meaning of "In the Pines" may be even more blurry, a vast continuum of different varieties of misery and suffering. "This unique, moody, blues-style song from the Southern mountain country is like a bottomless treasure box of folk-song elements," wrote James Leisy in his 1966 book "The Folk Song Abecedary." "The deeper you dig, the more you find."

The basic elements of the song remain similar from version to version, but the context can be altered with a few words. It may be a husband, a wife or even a parent whose head is "found in the driver’s wheel" and whose "body has never been found." Men, women and sometimes confused adolescents flee into the sordid pines, which serve as a metaphor for everything from sex to loneliness and death. The "longest" train can kill or give one’s love the means to run away or leave an itinerant worker stranded far from his home.

In the bluegrass and country versions popularized by Mr. Monroe, the song’s eerie qualities are rooted in the genre’s "high lonesome" sound, with fiddles and yodeling harmonies used to evoke the cold wind blowing. Lyrics about beheading drop out, but the enigmatic train is almost as frightening, suggesting an eternal passage: "I asked my captain for the time of day/ He said he throwed his watch away."

In other versions, the focus is clearly, as the novelist Ms. McCrumb notes, on a confrontation: "There’s a woman doing something not socially acceptable, and she’s been caught at it." In one case, a husband demands: "Don’t lie to me; where did you sleep last night?" In their traditional interpretation, the Kossoy Sisters begin: "Little girl, little girl, where’d you stay last night? Not even your mother knows." Despite all the variations of "In the Pines," these questions are almost never asked of a man. The woman may also be asked, "Where did you get that dress, and those shoes that are so fine?" and the answer is "from a man in the mines, who sleeps in the pines."

In Mr. Jordan’s jazz version, recorded for Atlantic in 1965, the singer Sandra Douglass makes the meaning even more explicit, drawing on a later Leadbelly version known as "Black Girl." Here the woman is in the pines because her husband has died under the train, leaving her with little choice but prostitution. "You caused me to weep/ And you caused me to moan/ You caused me to leave my home," she sings, perhaps to the cruel fates, perhaps to the ghost of her husband.

When Hole, the band led by Mr. Cobain’s widow, Courtney Love, played in New York in September, the final encore was "Where Did You Sleep Last Night." The sense of ghosts was palpable: a widow singing a widow’s tune, biting as heavily into each "don’t lie to me" as her husband had. But the ghosts were already there in the Nirvana version, which looked at death square on — Mr. Cobain’s voice cracks and pauses during the final line, then soldiers through.

Nirvana’s "Where Did You Sleep" is so definitive that the stray ends of the history of "In the Pines" come together. Mr. Lanegan sang his version as a spectator might have, with a bit of a leer. "I like the blood and guts theme of it: betrayal and murder," he says now. But Kurt Cobain inhabits the place from which the song sprang. His voice mixes fatalism and placidity much as Leadbelly’s had 50 years before; one hears a folkish impassivity that may well have been found on the 1925 cylinder recording as well.

Mr. Cobain’s identification with female rockers, from Hole to the Raincoats, encompasses the trespassing woman of the tale. And his origins in the pines-stripped lumber town of Aberdeen, Wash., take in the "simple people" who, as Dolly Parton notes, have always turned this cry of anxiety into a source of strength. "In the Pines" will have other versions, of course. But there is really no need for anyone to ever sing it again.

Variations on a Theme

The folk song usually known as "In the Pines" dates back at least to the 1870’s. Here are three versions:

Black girl, black girl, don’t lie to me
Where did you stay last night?
I stayed in the pines where the sun never shines
And shivered when the cold wind blows.Lizzie Abner, 1917

The Longest train I ever saw
Went down that Georgia line
The engine passed at 6 o’clock
The cab passed by at 9.

In the pines, in the pines, where the sun never shines
And we shiver when the cold wind blows.

I asked my captain for the time of day
He said he throwed his watch away
A long steel rail and a short crosstie
I’m on my way back home.

Little girl, little girl, what have I done
That makes you treat me so?
You caused me to weep, you caused me to moan
You caused me to leave my home.Bill Monroe, 1952

My girl, my girl, don’t lie to me
Tell me, where did you sleep last night?
In the pines, in the pines, where the sun don’t ever shine
I would shiver the whole night through.

Her husband was a hard-working man
Just about a mile from here
His head was found in the driver’s wheel
But his body never was found.

My girl, my girl, where will you go?
I’m going where the cold wind blows
In the pines, in the pines, where the sun don’t ever shine
I would shiver the whole night through.Nirvana, 1993

"…Cobain’s companion is Leadbelly, a favourite of folk aficionados who to this day perceive him as a giant of "black music", even though the vast majority of his fans were white. (When white producers brought Leadbelly to New York City in 1935 to play "traditional" music, Life magazine declared in a headline: "Bad Nigger Makes Good Minstrel".) Cobain’s swan song, performed on MTV’s Unplugged a few months before his suicide, was a cover of Leadbelly’s "Where Did You Sleep Last Night", about a woman who wanders into the woods after her husband is hit by a train. Cobain, so deep into the authenticity trap by then that he’d never escape, seemed to be making one last attempt not to "fake it", by reviving a song by his "favourite performer", and exiting the stage without an encore.

But Leadbelly, Barker and Taylor reveal, was by necessity a master of "faking it", a sophisticated musician of cosmopolitan taste limited to a repertoire of "Negro" songs and told by his manager to perform in prison garb. That manager was John Lomax, one of the early 20th-century giants of what has come to be known as "roots music". "The music that was, for Lomax, the most authentic," write the authors, "the most black, the most free from ‘white influence’, was the most primitive." That doesn’t mean Leadbelly was primitive, only that Lomax and, decades later, Cobain decided to believe that he was, the better to break the bonds of artificiality they felt modernity and celebrity imposed. Leadbelly was a tool. This shifty truth comes to us by way not of postmodernism, but of old-timey Marxist analysis. In 1937, the novelist Richard Wright, profiling Leadbelly for the Daily Worker, declared his coerced performances "one of the greatest cultural swindles in history".

But that’s not quite right, either. Wright recognised Lomax’s manipulation of Leadbelly (who later successfully sued Lomax), but he assumed there was a genuine Leadbelly behind the music, a real black expression minstrel-ised by the white man. In fact, many of Leadbelly’s songs came from white folks, who’d learned them from black musicians, who’d composed them with African inflections as reinterpreted by white musicians eager to add "floating" rhythms to the marching beat of Scots-Irish reels. The strongest argument of Faking It is for the endless "miscegenation" of music. Great popular music is always a collage of cultures, while the quest for authenticity all too often functions as a means of policing racial boundaries…"

The Suggested Upper Merged Ontology or SUMO is an upper ontology intended as a foundation ontology for a variety of computer information processing systems. It was originally developed by the Teknowledge Corporation and now is maintained by Articulate Software. It is one candidate for the "standard upper ontology" that IEEE working group 1600.1 is working on. It can be downloaded and used freely.

SUMO was first released in December 2000. It defines a hierarchy of SUMO classes and related rules and relationships. These are formulated in a version of the language SUO-KIF which has a LISP-like syntax. A mapping from WordNet synsets for nouns and verbs to SUMO classes has also been defined.
