Advance OpenStreetMap surveying with GTA04?
Hi, I'm looking for a handled GPS device for advance OpenStreetMap surveying and I hope the GTA04 Phoenix would do what I need. A few words on the project: 80-day mapping party, hiking, crossing the Alps (Summer 2012), 20 people involved (many of them for just a few days). Sleeping in Alpine Huts. Hiking and surveying during the day, if possible OSM editing in the evening (with a netbook). I need a GPS receiver to: 1- find our way 2- know what is already in OSM database (with full tags) 3- take pictures with advance surveying data (heading, precision) 4- save track with advance surveying data (precision) For 1 and 2, I am aware of some OSM-related software that should do it, see http://wiki.openstreetmap.org/wiki/Openmoko Still I do not know how well the GTA04 hardware is integrated into this. For 3 and 4, I need precision-related NMEA fields, as many as possible (at least HDOP -Horizontal Dilution of Precision-, other data like number of satellites, signal strength... is bonus). Saved in GPX and/or in exif. If possible: get a music alert when precision is low; have HDOP ready to show as circles in JOSM. For the picture, I need to save lat-long position + heading (angle to North) of picture (in exif or elsewhere; tilt is bonus). Post-processing is an option for position but probably not for heading and tilt. How good are the pictures? Are there online examples of pictures taken with the GTA04? Extra questions: If something is working easily on Neo Freerunner, is it then 100% guaranteed it will work on GTA04? Anyone using JOSM on GTA04 with surveyor plugin, taking live position from gpsd? http://wiki.openstreetmap.org/wiki/JOSM/Plugins/Surveyor If the above is already possible from a hardware point of view, is the software doing this already available? Or, would it be easy to implement? Ideally HDOP and the like should go into both exif of the pictures and gpx track, but post-processing (gpscorrelate or the like) is OK. I have no problem writing a few pages of (bash) script to pipe outputs or combine several command lines tools. However, hacking hardware drivers or working at very low level (read: close to hardware layers) is beyond my knowledge.

Re: Advance OpenStreetMap surveying with GTA04? / compass
Hi Ed, Thanks for the explanation on course! GPS-based heading is good for car driving and OK for road biking, not for slow travels: Position error jumps a few meters every seconds, hence if you do not move, the GPSr believes you move at 1 to 4 km per hour in random directions. So GPS-based heading must be taken with care for mountain biking and extreme care for hiking. Here I need to know the heading of a picture. Typical uses are: Example 1: stay in the middle of a path or track junction; take 4 pictures, in each of the directions of the 4 paths or tracks; mark the 4 ways on OSM with the way path, width, etc. Example 2: take pictures of signpost, side shrine etc. and remember on which side of the track they are. You need a compass heading for this. If current compass heading can be recorded with a bash command I can do the rest, typically develop a GUI that will send, at the send time, the command to save the compass heading and the command to take the picture (then with 'sed' I filter the heading/positions and write it into the jpeg image header with jhead). (Except that Nikolaus Schaller from goldelico says the camera driver is not working for the moment) Cheers, Mayeul Le dimanche 18 mars 2012 à 21:43 +0100, Ed Kapitein a écrit : Hi Mayeul, course is the same as heading. http://en.wikipedia.org/wiki/Course_%28navigation%29 So all the ingredients are there for successful logging! As for orientation, it depends on what you mean, course is your orientation towards the north. And the accelerometer provides orientation towards the earths surface, but i never used it myself.

Hi community, I want you to invite on Openmobility conference 2012! We are organizing a third annual conference standing on Openmoko ideas, but this year with major upgrade. From this year, Openmobility conference is going to be international event. What does it mean? We will have speeches, workshops and lightning talks in English for international audience. Also, location we had chosen has better international transportation connection. Date: 21st April 2012 Location: Prague, Czech Republic Transportation and accommodation: Will be announced on http://www.openmobility.eu/en/ before end of March. *What we want from you?* Speak about your work/hobby/community, whatever is open mobile or Open Source Hardware. I am looking for people from Openmoko community, GTA04, SHR and Qt Moko developers. But it's not limited only to these projects, you could represent MeeGo/Mer/Nemo, webOS, Open Source forks of Android, Panda Board, Arduino, Raspberry Pi. I am sure, I have forgotten other great projects like OsmocomBB etc. So, please spread this message in various communities. :-) *CFP: Write your ideas and topic proposals on our e-mail: confere...@openmobility.eu mailto:confere...@openmobility.eu before 28th of March 2012.* Please read more on: http://www.openmobility.eu/conference/om2012/cfp Best Regards, Martin Martix Holec PS: If you cannot have a speech, you can simply visit our conference. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: Advance OpenStreetMap surveying with GTA04? / compass
Mayeul, respect for the tour that you planned. I'm an OSM'ler as well and know a lot of alpine 'freaks' which are not related to OSM at all - so this journey seems a lovely marriage between both projects, but... How do you want satisfy power consumption of the device(s) that you will need? Actually you require a 230V line every night to charge a bunch of batteries. Devices like GTA0x last about 3-4 hours GPS tracking, Garmin Etrex or similair perhaps twice as long. Cellphones last long in standby or for only making pictures or voicenotes, but with GPS apps they're running about the same 3-4 hours. Low temperature will drastically reduce battery capacity or performance. I was investigating a lot in charging ideas, but there's nothing suitable for such a case. You either need a huge pack of batteries, or a huge amount of accus and chargers and power suppliers. For example: a bycicle dynamo delivers enough energy at about 20 km/h to keep the GTA0x alive in GPS tracking mode. A solar cell delivers enough energy to keep a GTA0x in 'sleep mode' alive. Exchange GTA0x against any other mobile phone. So how would you solve the energy issue?

Re: Advance OpenStreetMap surveying with GTA04? / batteries
Hi, Thanks for the questions and the comments! We will sleep every night in a managed alpine hut or hotel (depending on place). I did the hike and sleep in a tent 15 years ago and know I will not resist 80 days now! Last Summer I crossed the Dolomites with a 8 kg backpack. This year I will carry less of friends' stuff and more of high tech; this gives room for another battery. Last October we did a 3-week mountainbike tour (Sardinia) in similar conditions (hotels...). A set of 2 LR6 batteries lasted typically 7 to 16 hours depending on device. Issue in mountain is that sometimes there is no public 220V power plug. Experience last Summer (8 days in Dolomites) told us that sometimes the hut keeper has a power plug even if this is not public; given that we contribute to free libre maps, we hope in these case to have access and plan to ask by email well in advance if power is available and if we can use it (we already have the full email list). I'm more afraid of 12 V plugs but let's hope they will be rare. I might bring my old Garmin EtrexH as a backup. With a very small added weight, I get 2 days of hike. For LR6, I use Eneloop batteries (sorry to advertise this), which do not discharge as Ni-MH do and have better resistance to cold (typically an entire snow-shoes hiking day around 0° C). Several people asked me what about solar cells? and I was not sure. So your comment A solar cell delivers enough energy to keep a GTA0x in 'sleep mode' alive is very precious for us, thanks!! Sure, we will try to reduce consumption and, yes, I'm not sure the above will be enough. We'll try to make a 2-3 days test in May!
