GanosBase Geometry Pyramid is used to display two-dimensional geometry big data at high speeds.
Data requirements
Data tables can contain only the following types of spatial data: Point, Line, Polygon, MultiPoint, MultiLine, and MultiPolygon.
Each data record must contain an ID field whose value is a unique positive integer of the uint4 or uint8 data type.
You must create spatial indexes on the geometry fields.
Geometry data supports all
EPSGcoordinate systems. MTP-formatted geometry data supports only theEPSG:3857 and EPSG:4326coordinate systems.
Hardware requirements
We recommended that you configure 32 cores, 64 GB of memory, and 500 GB of SSD storage capacity. This allows you to process 0.1 billion data records within about 15 minutes.
In most cases, the extra storage space that is occupied by the produced pyramids does not exceed 10% of the storage space that is occupied by the original data.
