Release Notes

September 24th, 2024 (v1.4.0)

Module tiler

New

• Add tile_resolution to 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 plv8 extenstion installed).

December 23, 2023 (v1.2.2)

Module tiler

Fix

• Fix recommended zoom in __clip_all_tiles internal function. This corrects some problems with tileset's creation.

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

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

December 22, 2022

Module quadbin

New
