Re: Advance OpenStreetMap surveying with GTA04?
Hi Liz, Yes you are right 8-( The issue from a GTA4 point of view is that I would need to load one dataset more in the GTA04: both new and old OSM datasets. Or maybe merge the datasets and build a map suitable for GTA04, clearly showing the licence status... From OSM point of view (so maybe better to continue off-list) I should check with JOSM licensechange plugin [1] everything around the path. Some highways (roads, tracks, some paths) should be visible from Bing and Italian PCN. Yet another thing to add in my TODO list for the ViaAlpina.

Re: [Gta04-owner] Advance OpenStreetMap surveying with GTA04? / camera heading
Hi, Thanks Christoph. Comments below: There exists a simple hack that reads the raw acceleration values from the chip and delivers them to userspace using a sysfs file I've read [0] but could not find it description of this hack. Any pointer and sample strings? The LSM303DLH combines both 3D compass and accelerometer, so is the HMC5883L usefull for this application? So one idea is to put some tilt logic in the code here: http://gitorious.org/vala-compass/vala-compass/trees/master/src Or write a piece of code that takes the raw data and output tilt-corrected magnetic heading. I found out some math and code (for Arduino) that could be re-used. Most interesting are [3] to [5]: [1] Has nice geometric discussion and code, but cannot correct for tilt over 40 degrees. Saysthere are other (more complex) algorithms for tilt 40°. [2] Give some pointers to scientific articles, including I believe for 360 degrees correction. Note that typical use is keeping the device vertical, so code in [1] is not OK [3] Discusses the LSM303DLH chip included in the GTA04, and gives 2 links for code computing the tilt-corrected heading: [4] Arduino code for LSM303DLH [5] In Ressources tab: library for the ARM mbed development board that interfaces with the LSM303DLH 3D compass and accelerometer carrier and provides the tilt-compensated magnetic heading Isn't [5] the closest to what would be needed?
