Release Notes
June 26th, 2026 (v1.5.0)
Module h3
New
Added H3_POLYFILL_TABLE procedure — polyfill a query or table of geometries into H3 cells and write the result to an output table.
Module quadbin
New
Added QUADBIN_POLYFILL_TABLE procedure — polyfill a query or table of geometries into Quadbin cells and write the result to an output table.
September 24th, 2024 (v1.4.0)
Module tiler
New
Add
tile_resolutionto all tileset creation options. This new setting allows controlling the size of the tiles when rendered in a map. Higher values produce larger tiles.
Fix
Support empty properties in CREATE_POINT_AGGREGATION_TILESET procedures.
Fix CREATE_SIMPLE_TILESET procedure in order to support any geom column name.
January 18th, 2024 (v1.3.0)
Module quadbin
New
New QUADBIN_DISTANCE function that returns the distance (number of cells) between two quadbin cells.
Fix
Improved precision when calculating cell indexes from latitudes close to the poles (±90º).
Module tiler
Fix
Fixed a problem when parsing quotes inside the input query in CREATE_SIMPLE_TILESET and CREATE_POINT_AGGREGATION_TILESET procedures.
Improved bounds calculation to get the exact value when using h3 cells in the CREATE_SPATIAL_INDEX_TILESET procedure. This applies when the Analytics Toolbox is installed with the h3 module (depends on having
plv8extenstion installed).
September 8, 2023 (v1.2.1)
Module tiler
Fix
Fixed wrong parameter formatting in
CREATE_SPATIAL_INDEX_TILESET.
August 7, 2023 (v1.2.0)
Module h3
Improvement
We have improved the performance of H3_POLYFILL.
New
We have added to the function H3_POLYFILL different polyfill modes: center, intersects, contains.
Module quadbin
Improvement
We have improved the performance of QUADBIN_POLYFILL.
New
We have added to the function QUADBIN_POLYFILL different polyfill modes: center, intersects, contains.
July 14, 2023 (v1.1.2)
Module tiler
Fix
We added some changes in order to support capitalized columns when using CREATE_SIMPLE_TILESET.
Module quadbin
Change
We have updated the formula used in QUADBIN_FROMLONGLAT so it gets standardized. In addition a new implementation of QUADBIN_TOCHILDREN has been added in order to increase performance.
June 6, 2023 (v1.1.1)
Module tiler
Fix
We added some missing metadata that was negatively affecting the usage of CREATE_SIMPLE_TILESET, CREATE_POINT_AGGREGATION_TILESET and CREATE_SPATIAL_INDEX_TILESET.
May 5, 2023 (v1.1.0)
Documentation
Improvement
We have improved the installation guide, allowing now to use a Python script as installer. \
Module h3
New
We have released a new module in the Analytics Toolbox for PostgreSQL in order to provide native support for operating with the H3 spatial index.
This new module named “h3” includes the following functions: H3_BOUNDARY, H3_CENTER, H3_COMPACT, H3_DISTANCE, H3_FROMGEOGPOINT, H3_FROMLONGLAT, H3_HEXRING, H3_INT_TOSTRING, H3_ISPENTAGON, H3_ISVALID, H3_KRING, H3_KRING_DISTANCES, H3_POLYFILL, H3_RESOLUTION, H3_STRING_TOINT, H3_TOCHILDREN, H3_TOPARENT, H3_UNCOMPACT
March 7, 2023 (v1.0.1)
Module tiler
Fix
We have added the creation of an index with the tile and the clustering of the tileset by that index in the CREATE_SPATIAL_INDEX_TILESET.
December 22, 2022
Module quadbin
New
Quadbin/quadkey conversion functions have been added to ease the conversion from quadbin to quadkey and from quadkey to quadbin indexes.
