comment Would it be possible to use geohash for proximity searches?
Ah, OK. CouchDB also had spatial indexing now, probably also using geohash.

Also, is memory a real limitation here or just theoretical?

If you have the memory, just slice the numpy array instead of building a redundant dictionary.

Are you still trying to find the maximum value of each pixel as in previous questions?

comment How to project pixel coordinates in leaflet?
containerPointToLatLng refers to screen coordinate relative to the map container div, so it won't help here.

comment How do I convert Eastings and Northings projection to WSG84 in geopandas?
I don't know the source of your specific problem, but it's a common problem for beginners to reverse coordinate orders since in we generally say (latitude, longitude) and (northing, easting), but most mapping software uses cartesian ordering (x,y) and is therefore in a different order.

Do you mean northings and eastings are reversed?

Insert the unioned geometry into a table with an autoincremented id column.
