Geo-spatial Land Price Database

Build a database of land prices with geospatial maps.

• Information supply, transactors can upload information and receive credits.
• Information demand, searchers/investors can spend credits and obtain aggregate information.

Usage scenarios;

1. Sellers search for information about value of their properties when estimating value
2. Buyers search for information about value of properties before buying

A more generic application of this idea is to replace all government/public information services that we currently pay for with cheaper crowd-generated data.
