CADObject vs. GeoGrid vs. PostGIS vs. Python Comparison Chart

CADObject is a unique development of "ExonIT" LLC which allows to create of application systems and WEB services that provide interaction between CAD and GIS apps. Creation and managing of project documentation exacting the customer's requirements. Decreasing the operational costs thanks to real-time updating of documentation. Maintenance of the history of the object lifecycle with instant access to the needed information in real-time. Integration with existing enterprises' systems. The main difference between CADObject and other similar products is, that in process of data exchange between CAD and GIS, CADObject creates an object data model whilst converting. During this process, all the standard graphic symbols are recognized, united into separate objects according to a certain classifier, and transferred to a spatial database. Each object has a specific entry in the database, which allows the development of analytical spatial solutions.

PostGIS is a spatial database extender for PostgreSQL object-relational database. It adds support for geographic objects allowing location queries to be run in SQL. In addition to basic location awareness, PostGIS offers many features rarely found in other competing spatial databases such as Oracle Locator/Spatial and SQL Server. PostGIS can utilize the faster GiST building support API introduced in PostgreSQL 14. If compiled with recently released GEOS 3.10.1 you can take advantage of improvements in ST_MakeValid and numerous speed improvements.
