Release Notes

May 5, 2023 (v 1.2.0)
Module statistics
New
We have added a new module named “statistics” in the Analytics Toolbox for Snowflake which has a set of geostatistics functions to compute the Getis-Ord Gi* statistic and the Moran’s I spatial autocorrelation:
Getis-Ord Gi* functions:
​GETIS_ORD_QUADBIN​
​GETIS_ORD_H3​
​P_VALUE​
Moran’s I functions:
​MORANS_I_QUADBIN​
​MORANS_I_H3​
Module h3
New
We have incorporated two new functions to the “h3” module of the Analytics Toolbox, namely H3_CENTER, which returns the center of an H3 cell as a GEOGRAPHY point, and H3_RESOLUTION which returns the H3 cell resolution as an integer.
Module transformations
New
We have added support for the ST_CONVEXHULL function, which computes the convex hull of the input geographies (the smallest convex geography that covers all the input ones)
April 4, 2023 (v 1.1.1)
Module lds
Improvement
We have improved the performance in CREATE_ISOLINES, benefiting now from parallelizing requests to the API.
Change
We have updated the LDS module to be aligned with the new usage quota model, working as an annual budget and combining consumption across all supported LDS services.
​
March 7, 2023 (v 1.1.0)
Module lds
New
We have added object type support for the options parameter also maintaining string type support as until now in GEOCODE_TABLE, GEOCODE_REVERSE_TABLE, CREATE_ISOLINES, , GEOCODE, GEOCODE_REVERSE, and ISOLINE.
January 31, 2023 (v 1.0.0)
Module tiler
Improvement

December 22, 2022
Module lds
Improvement
We have added the possibility to configure more options as parameters when executing the functions to CREATE_ISOLINES. These new options, which depend on the LDS service provider, allow the user to configure more transportation modes such as truck or bike, the possibility of specifying departure or arrival times allowing the creation of reverse isolines, and other options like different routing modes.
Added new confidence/relevance metadata to the results of the geocoding function GEOCODE_TABLE.
Module quadbin
New
Quadbin/quadkey conversion functions have been added to ease the conversion from quadbin to quadkey and from quadkey to quadbin indexes.
Module h3
The H3_BOUNDARY function for invalid geographies has been fixed.
