This includes applications related to  engineering, planning, management, transport/logistics, insurance, telecommunications, and business [1].

[3]) to index multi-dimensional data (coordinates, polygons, rectangles, among others). Such a step enables the rise of Geo-spatial databases for gathering, analyzing and querying such data (i.e. Esri, GIS-planning and Database extensions like GeoMesa (for Hadoop), PostGIS (PostgreSQL), Oracle, CouchDB, among others) for a more customized (in case of geo-databases) and specialized use-c…
