GanosBase Geometry Pyramid accelerates the rendering of two-dimensional geometry big data.
Data requirements
Supported geometry types
Geometry Pyramid supports the following 2D geometry types:
| Category | Types |
|---|---|
| Atomic types | Point, Line, Polygon |
| Collection types | MultiPoint, MultiLine, MultiPolygon |
ID field
Each data record must include an ID field that meets the following requirements:
-
Data type:
uint4oruint8 -
Value: a unique positive integer across the table
Spatial indexes
Create spatial indexes on all geometry fields before building a pyramid.
Coordinate system support
| Data format | Supported coordinate systems |
|---|---|
| Standard geometry data | All EPSG coordinate systems |
| MTP-formatted geometry data | EPSG:3857 and EPSG:4326 only |
If your MTP-formatted data uses a coordinate system other than EPSG:3857 or EPSG:4326, convert it before building a pyramid.
Hardware requirements
The following configuration is recommended for production workloads:
| Resource | Recommended specification |
|---|---|
| CPU | 32 cores |
| Memory | 64 GB |
| Storage | 500 GB SSD |
At this specification, Geometry Pyramid can process approximately 100 million records in about 15 minutes.
Storage overhead: The pyramid index does not exceed 10% of the storage space of the source data.
