I am new to the GIS-World and just learned a couple of tools. Now I want to start with my actual project, but since i don't have a overall understanding I would have to hear your opinions about the feasability of my ideas.
I have a lot of data points which refer to car drives getting tracked by GPS. I want to group points which are really close to each other to be able to compare their sensor values.
First I thought of rounding their values to something around 5 decimal places to group them, but then the points would not lie on the street anymore.
My actual plan is to load german street data from OpenStreetMap-Data using osm2pgsql into PostGIS. Then I want to calculate the distance of my data points to the closest street using somehow (maybe ST_Distance). Then I would like to find some algorithm to group points on the street by some flexibel interval (e.g. 5 meters).
Do you think this might work? Any other tools or data I should have a look for? Just trying to minimize programming time invest into some system which might not be able to work.
