Review on GeoSpock DB by Steve Brethorst

I like that it has geospatial indexing which gives your queries better performance than other databases without adding too much effort or time spent setting up indexes manually as some others do! It supports PostGIS/Shp files so you can store spatial information in SQLite format.

Not all features are supported by this product but their support team have been very responsive when we needed help solving problems using different tools they provide free trial versions of those products if required before buying them. We used SpatiaLite library within our Android application to extract location from GPS coordinates into sqlite table structure then query these tables with standard sql commands such as WHERE clause.
