Found today really useful tool: PoGoMap
It's relatively easy to setup, local server which allow you see in browser map of all pokemons around some Lat/Lan
Just install python if you don't have it
Download archive unpack it
Run "easy setup" scripts
And then make "bat" file with something like this:
d:\Python27\python example.py -a google -u your_google@email -p your_password -l "55.89 37.44" -st 10 -P 7777
pause;
-P 7777 - this is port where server run - for me default value not worked.
And then open in browser http://127.0.0.1:7777/
Reload page periodically while it's scan for new pokenons.
If in command windows you see errors - probably server just overloaded right now - this is happens really often.
I already found with this tool many places with rare pokemons around me I don't know yet.
Helpful post. Thanks!
