Topic: Adding pictures with coordinates.
started by: Quinn
Posted by Quinn on Jan. 23 2002,9:39 amWe ran across another neat website that offers a software that will allow anyone to add pictures to his/her website as well as show a map with pinmarks of each location a picture was taken. The way it works is your GPSR and Digital camera both have a clock within them, when both are turned on and the tracking mode is running on your GPSR you can enter into the software the clock time differences between the two, this way the GPSR will know exactly where you were when that picture was taken. Now when you upload your pictures into the software it calculates each picture and places a coordinate to it and generates a map for that picture. To read more about this software please visit < RoboPhoto > and check it out. This would make a great idea for a online scrap book or perhaps even some sort of virtual game. I am turning wheels in my head to see how we can better use this idea.

Posted by Quinn on Jan. 24 2002,5:27 amhmmm...I would check out your manual for that info, if you don't have it anymore maybe we can find it on the net within the makers webpage or via e-mail to the company. what model is it?

I've got the manual at home, but don't remember seeing a reference to an internal clock. That doesn't mean there isn't one, of course.
The model is l'espion and it's marketed by digitaldream. One of the smallest cameras I've seen, but it doesn't have some of the gizzmos that more expensive, and larger, cameras have.
To get at the pictures I have to connect to the PC via a USB cable. I suspect that the clock, if there is one, will require someone to have cracked how to get at it.
Thanks for the help.
Posted by dgridley on Jan. 25 2002,10:07 pmI would suspect that your camera does have some sort of internal clock but what the RoboPhoto program does is read the EXIF data written to the digital image file (shutter speed, etc.) and the info would be stored there that the program is looking for. For complete info on EXIF, go to:

Hope this helps...
Posted by Quinn on Jan. 28 2002,9:30 pmGetting back to this program I was out testing it on a trip to Buffalo, Ny yesterday. This is way cool! What I did was took my Olympus camera and plugged it into my computer and had the computer correct the internal clock of the camera, this was after I used my GPSR to set the clock of my computer while being plugged into it. so anyways with both camera and GPSR at the exact time I went on my way with the GPSR turned on and tracking my moves. I took several pictures also taking notes while doing so of where I was standing when I did this. I marked all of my coordinates in a paper binder as well as the picture number. After my trip I came home and uploaded the gps and pictures into the program. The program generated a perfect map with thumbnail pictures I could click on to enlarge to full size. Each picture was in the exact spot I marked at the time taken and at the bottom of each pix was the coordinates listed below. This is awsome to say the least! this fellow did a great job making this software and it will come very much in handy when out dashing as well as caching.

Now look what you did, now the credit card in my wallet is trying to tell me that I just have to have a new digital camera which will timestamp pictures as well, for geodashing.

Like I said, most cameras produced have this feature. It's actually info regarding time taken, etc. embedded into the photo code. This photo album software detects this EXIF data, strips it out, and makes use of it to set up the album. You probably have all you need now.

I don't think my l'espion outputs the information, if it does have a clock that is.
I tried the program and it seems very good, but none of my pictures had the timestamp information on them.
In fact, l'espion seems to download its pictures in BMP format from the program that aquires the image from the camera to the program which displays them, so maybe that's where the data gets lost.
I'll see if I can get the digitaldream downloading software to interface with the new program.
Posted by dgridley on Feb. 03 2002,9:41 amOops! There's the rub.. EXIF is supported only by JPEG (JPG) and TIFF files... not by BMP. Surprising that it would export the files as a BMP, considering it would be more advantageous to compress the files using JPG.
>Exif Formats (TIFF and JPG) Exif is a standard for image files created with digital cameras and other input devices. The standard is set by the Japan Electronic Industry Development Association, and formally it is called the Digital Still Camera Image File Format Standard. Exif files contain either uncompressed TIFF images or compressed JPEG images. In addition, these files can contain many comment fields of various types.<
Need to get another camera, dude...

I managed to sort of interface the digitaldream twain program to the Robo program. It recognised that there were 8 pictures in the camera, but said they were an incompatable protocol.
So, it seems that my l'espion wont work with that program.
I like the l'espion, it's a very small unit and takes a reasonable picture in good light. As a Christmas Present, which is what this was, it's great. All I need to do is leave a suitable time period before suggesting I might get another digital camera, as the present was so good it's made me want to expand on it's functions. .
