Hi,
We have 2 geojson files.
File 1 : City (3500)
File 2 : Building (200000)
We need a python script for test if Building Polygon is inside City Polygon.
At first, the script should just answer yes or no.
Hello sir
I have rich experiences of geocoding and am familiar with geopy package of python. I am able to do this work successfully. I can start the work right now.
Best,
Zhang
I can write simple Python script that will read your City and Building files (with geojson inside) and next it will check each building for each city(is it inside city polygon or not).
I can complete it in next 24 hours for just €100.
Thanks.

hi
seems really straightforward to code!
Can you show me the files?
I think the objective is clear enough
--plus: I have recently worked with geoJson format again
Hello.
As far as I remember, there is available algorithms to check one polygon inside another polygon.
Is not there any specific requirements about performance? Thanks
Also, I would like to check JSON files before be awarded. In order to make sure it's easy to parse and build polygons
Hello,
For this project I would use the shapely and rtree modules.
If in the future an API is needed I would build a web API using Tornado web framework; if the startup time / memory consumption is an issue we could also load the data into Postgres (PostGIS) and index it.
How large are the files?
Best wishes,
iticus
Hi,
I have read your requirement.
1] I can write python script as you require for city and buildings.
2] First we need to check if building polygon is inside city polygon.
I am experienced python coder and I am interested in this project.
Please send me a message so that we can discuss more now.
Thanks,

I presume both geogson have polygon data. I can check if each polygon in building is fully contained in city file. This may however take a long time to run. So I can code for few samples to work .
