Geohash idea for Bus stops (and other location redundancy) de-duplication

[answerquest]

From Pune Open Data portal, we have lat-long data of bus stops, but it is non-unique and heavily repeating in some cases. The BRT stops were there in a separate unique list so they are easy to pry out, but the larger dataset of non-BRT stops needs work.

Geohashes resolve lat-long values into square areas. So, a pair of lat-longs that are very close to each other but not the same can be resolved to belong to the same geohash. So, this could be a way of clustering the stops data. Links:

  Wanted: A combination of these tools. A map where we can fix the precision (like, 5 chars), where we can click to reveal the geohash for that area, and where we can type in lat-long or geohash to browse to that place.
  And, something more: We should be able to input other kinds of hyperlinks like google maps shortlinks or long URLs, and get the corresponding geohash. The tool's URL should accept parameters.
