Reverse Geocoding Using Google API and lNet

I have an application on my blackbery that logs my traveling using the
built in gps and saves it to a kml file. I want to use this data to
generate trip reports for tax purposes etc. The kml file contains the
lat long waypoints tracked as I travelled. The app can not export to a
readable csv, so I want to create my own app.

This is where this program comes in. It uses reverse geolocation to
get the begin and end address from the lat long values entered into
edit boxes. Thought I would post the source on my website.

I used lNet as it has a HTTP client that handles the internet stuff
for me.

The final program will be able to do following:
Load and batch extract data from multiple kml filesLoad the selected
trace onto a google map inside the programCreate reports and export to
csv, pdf etc.

Good idea - and thanks for posting the source!

If you want to, you could post screenshots here:

and/or a project description here:

Will post screenshots on the Wiki page once the main app is finished.

I created an application that can batch extact data from multiple
files dropped onto the form. It then saves the data to a csv doc.

Next feature to add is opening the trace in a map component to view
travelled path if you want to check an address.

I will add the source soon, just need to clean up a bit more. No much
time though as I travel often.

Just for interest sake, I just started python and I found it a lot
easier to parse data. Python has powerful built in functions that
makes this easier. I am going to try and build a gui for this as well
using pyqt.

application is not time/memory critical, don't need low level access
and you're OK with runtime dependencies, it might fit OK.

Hi digeo,

Wondering whether you ever got around to publishing the source code to
that tool... (I've got a couple of kml or gpx files that I want to
anonymize by scrubbing the first and last couple of waypoints)...

Thanks,
BigChimp
