To turn a S60 Python .py file into something installable (.SIS).. you can used Ensemble.

You need to install OpenSSL too, and put include it in your Path.

Then run ensemble and turn your .py into a .sis.
Include any permissions your SIS will need... like access to GPS and networks etc.
Then once you have a SIS file sign it using Symbian online open signing.. again with all permissions required.

Then install to phone.

NOTE... if Python is installed to C on your phone (Phone memory) then your SIS should be installed there too otherwise you may just get the appl flash up a blank white screen for a second then close again.

eg of syntax for all permissions you can get on Nokia N82 GPS camera phone.

Then sign the SIS using Symbian Open Signing online...

Cell Positions

http://spectrumonline.med.govt.nz/licence-search.html

Enter into LICENCE either:

telecom
vodafone

The main license types for cell phone base stations are SZ, SY, and SX (relates to transmit power, SZ is most common).

From here you can drill down to find LAT/LNG for each transmitter.

Google Maps - Quadtree tiling system

So Google and other online mapsite using a tiling system to transfer large images.

These images are cut into smaller ones, based on a nested hierachy.... known as Quadtree. Good explaination here


Google use q,r,t,s (0-3) to denote one of 4 corners of a tile.

So to find your location run this Python code....




Run it like this:

python googletiles.py 17 -43.525 172.616

Spherical Mercator (ESPG:900913) coordinates for lat/lon:
(19215525.222771712, -5392226.689463486)
17/128383/47899 ( TileMapService: z / x / y )
Google: 128383 83172
Quadkey: 31311030123311311 ( 14851095925 )


Substitute the QUADKEY values as follows
0=q
1=r
2=t
3=s

Then type that list of letters into this page...




Here's an example for Christchurch, NZ
