Develop tool to determine size of selected area on satellite map (javascript)

Hi there,

We’re looking for a developer to assist with developing a simple proof-of-concept.

We want to be able to define a polygon from a map, save it as a polygon with scale, and then further define subareas within it, estimating the size of these subareas and displaying them with a simple calculation. There’s no real styling or polish or optimization required here – we just want something that works!

We’ll provide a specific spec sheet to shortlisted candidates. Experience working with maps required.
