Police Station Map and Mapping Information

[Shruti Lakhtakia]

Hi,

I am a Ph.D. student working on crime and development in India, and I am looking for:

(1) a map of all the police stations in India, as well as their jurisdictions,

(2) information on how police stations can be mapped to the assembly constituencies of their respective states.

Please do let me know if you have any experience working on this, or any suggestions on how this information can be collected.

Thank you!

Sincerely,

Shruti Lakhtakia

u can search in google map ( type it  as police stations, first u hv to zoom the area, then u can type, if u search it for wide area in google map, u will not get full data.so u hv to locate some area and search the police station) and make it as kml files, then u can process it in Arcgis. U can prepare the map also.

Hi Shruti,

Sharing possible ways that I know of to find and build the data you're looking for from the generally available map platforms. Sentences in brackets give more background info for people new to the subject. Note: I am adding an important caveat at the bottom.

OpenStreetMap or OSM (the all-open commons alternative to google maps that you'll find members of this community earnestly pitching for) way:

Relevant tag/key-value pair : "amenity=police" . Link: https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dpolice 

Query on Overpass Turbo (the "backend" of Openstreetmap and the quickest way to search download specific data): https://overpass-turbo.eu/s/LX6

Google Places API (the more complicated "backend" of Google maps which while having more coverage for now, is way more restricted both technically and legally and the reason why you'll find members of this community earnestly pitching for moving to OSM / enriching OSM instead )

... lists "police" as one of the POI types than can be searched and retrieved programmatically.

Link: https://developers.google.com/places/supported_types

Note: Since the term "poiice" is generic, the direct search may also throw up places that aren't police stations, eg: police training institutes. It's safe to assume any dataset you get will be messy and will need considerable manual work on it to get to an acceptable stage. 

Caveat: We cannot expect full coverage or any proper answers about extent of coverage (The usual answer to "does this cover everything?" is "Nobody knows!") because that requires some official institution putting the data out there, and if there had been one then one wouldn't need to search on general map platforms. So what you get here is typically a perpetual work-in-progress cobbling-together of data by ordinary people volunteering time and effort. It will probably never be "complete" but it's much better than nothing. The remedy to lack of coverage is to start contributing to the common well and get others to do the same.

Hi Nikhil and Naveen,

Thank you so much for this, it's very helpful! I am one of those new to the subject, so the bracketed sentences very relevant.

I'll spend some time on this and get back to you if I am able to produce some outputs that would be useful for everyone!

Thanks once again.

Sincerely,

Shruti
