On Friday, 2007-11-02 I started with OSM. The first task was to
get an GPS-device. I decided for a simple GPS-Data-Logger without
display, routing and trackpoints. For the first steps the Royaltek
RGM-3800 should be enough. The price was 60.- Euro. I fetched some
batteries too and charged them.

Saturday, 2007-11-03 I did the first traces in the south of my hometown Ratingen, NRW, Germany. I did it by bike, set the interval of the GPS-points to 10 seconds, mounted the device in front of my and drove about three hours,
tracing the streets. I used the software which was delivered with the device and used (I don't know if its allowed to say it here?) >SAM-ELGOOG< to take
a first look on my results.

On Sunday I set the interval between points to 5 seconds and put the
data logger in my pocked while driving. Now I think the results
look a little bit more inaccurate then those from the day before.
But why? NEVER change TWO parameters at the same time during a test phase!
I set the interval to 10 seconds again and tried it with the data logger
in my backpack.
I traced about 6 hours in the south, centre and east of Ratingen.

After the muscle part I have to begin the brain part now.

I need to translate the Data from NEMEA format to GPX format and then
to learn how to upload the data to OSM and edit the tracks with JOSM
to get real street data.
