Hallo Jan,

I have seen the last commits from you about adding GSM based localisation.

First this is great, that it reaches the framework!

This brings me some questions:

1. This has been especially a surprise to us, as we at openBmap have currently been thinking how to bring this to the users. We already did some work on exporting the database under SQLite files for every country. And on top of this, a small DBus service to bring the localisation to everyone...

I am no hacker, but still would have hoped to bring some help on this... If you are interested, how would you like to proceed?

2. I had a look at the code, and suppose you are building your database out of the data from CellHunter. Am I correct? I think CellHunter is a great project but we still think that we should log HPV-Dops, speed, in order to be able to filter low quality measures. This is currently discussed on another thread on this list [1]. If you combine a high speed with low Dops, you end up with very unprecise positions for building the cells coverage, don't you think?

I would like to know what is your opinion about all of this. Are you interested in our approach, and are you interested in taking in consideration in your code the extra fields our data contains (Dops, speed, software id, software version, etc.) to possibly filter measures to keep only higher quality?

Thanks,

Onen
