"In addition to whatever you decide to do with aerial imagery, I'd recommend just bringing a hand-held GPS unit that you have on whenever you're driving around the city. Then (when you get back?) upload that to Open Street Map…"
"If my memory serves me correctly from a study I did several years ago, Orbcomm is a store-and-froward satellite system. When a satellite happens to pass overhead, you dump your data to it, it then will drop your data off at the next available…"
"I'm pretty sure that the panda board (looks similar to the beagle board) doesn't work with CUDA, which I believe is nvidia only. Its possible that it will work with OpenCL, but I'd be a bit surprised there too.
"Yeah, I've had good luck setting up repeated timed shots with my SD1000. Once you read through the instructions on getting it setup, its really easy. I think there are even scripts on the site already set for this, you just need to…"
"Awhile back I ran some calculations on what kind of theoretical performance you could get from wing-tip spaced stereo cameras.
You can see the attached matlab (I actually ran it in octave) script that does the calculations, but the…"
"Yeah, if you've got the infrastructure to wire it in, that is definitely the way to go. In theory (who knows about in practice) the latency between the command to take the picture and the actual capture should be approximately…"
Some amateur radio folks put together a DGPS reference station a while back. Used Motorola Oncore GPS, which the UT+ model supported "site survey" mode. A survey took about 3 hours but then you had your own reference.
You can find the HW docs here: http://www.tapr.org/gps_vpib.html
and the DGPS C code here: http://www.tapr.org/software_library.php?dir=/gps/DGPS/N8PXW Control software here:http://www.tapr.org/gps_tac32.html
You can still find these GPS units on ebay, but since they are 10 years old, current models are likely more accurate, as receiver noise plays a significant role.
