[OSGeo-Discuss] Mobile GPS data collection...

[Gary Lang]

Very interesting.

Might we be able to say that data collection is optimal using handhelld technology and field data management is optimally done witgh laptops (we'll leave aside the difference between clamshells and tablets)?

Subject: [OSGeo-Discuss] Mobile GPS data collection...

Hi,

I was informed by Cameron about this interesting thread, hence I just 
joined the list. Hopefully I can contribute to this subject and/or find 
opportunities to collaborate.

I've been doing mobile GPS data collection for over a year now in the 
context of Locative Media projects. I started out with GeoSkating 
(www.geoskating.com) gradually building this into a client/server 
platform GeoTracing (http://www.geotracing.com). GeoTracing is in the 
process of going OSS (geotracing.codehaus.org). We are still seeking 
more developers....

Something about client-apps:

I have mainly used Java (J2ME Midlets) on smartphones with Bluetooth GPS 
(JSR-82 API). Apart from the bugs in the phones and pecularities with 
operator settings this went reasonably smooth.

I am now researching the use of PDAs and Desktops (Macs, PCs etc). 
Instead of developing custom software I am challenging the use of the 
webbrowser with AJAX to run the client application. For the desktop this 
was sucessful modifying a small Python app called mehere 
(http://mehere.glenmurphy.com/), basically having a GeoTracing client.

Next: PDAs. I have been playing with the Minimo browser and found this: 
http://weblogs.mozillazine.org/dougt/archives/016719.html But I'd love 
to see someone with .NET experience develop a MobiTracer

Ok, there is much more on this subject. My approach was to treat data 
collection as a portal/CMS activity combined with media/POI geotagging, 
using a leightweight custom XML protocol (no WFS-T). (Ok I did not have 
a GIS-background).

(Unfortunately I am about to leave for a 4-day holiday away from email 
so I can read/respond earliest on monday).

best,

--Just
