Release notes

May 22nd, 2024 (v1.14.0)

Module http_request

New

  • We have a new module named “http_request”. It allows making requests to external endpoints through the function HTTP_REQUEST

Module import

New

  • We have a new module named “import”. It allows importing tables for a given URL containing a file in any of the formats supported by the CARTO Import API. The procedure in charge of this import is IMPORT_URL.

April 18th, 2024 (v1.13.0)

Module raster

New

  • Added new RASTER_VALUES and RASTER_AGG_VALUES procedures:

    • RASTER_VALUES obtains pixel values from a raster where it overlaps with an optional vector data input. It accepts SQL expressions, including operations between bands.

    • RASTER_AGG_VALUES obtains aggregated values from a raster's pixel values where it intersects with a vector data input. It accepts any SQL aggregation expression.

Module clustering

Fix

  • Update ST_CLUSTERKMEANS in order to avoid generating fewer clusters than requested. The maximum number of clusters now will be equal to the number of different points passed.

Module lds

Fix

  • GEOCODE_TABLE not working properly for “geom_column” parameter's value different from “geom”.

March 21st, 2024 (v1.12.0)

Module lds

New

  • All external functions (including those used by the procedures in the lds module) now use a single, unified endpoint. This also simplifies the manual installation of the Analytics Toolbox.

  • GEOCODE_TABLE now uses async batch geocoding with TomTom, boosting the geocoding speed considerably. Also matching by rows is applied ensuring that the address that reaches the TomTom endpoints is as similar as possible as the table value.

Module data

New

  • Add ENRICH_POLYGONS_WEIGHTED procedure. This new procedure enables users to enrich polygons with a provided data query by taking into account the ratio of a specified feature between the intersected and original areas in a way to weigh the contribution of each feature in the enrichment. Note that the original methods only use the geographic area of intersection for this weight.

  • Replace LDS_QUOTA_INFO procedure with GET_LDS_QUOTA_INFO function. This new function allows checking your currently consumed quota with a single query, without the need to store the result as a table.

Fix

Module data

Change

  • Change location of spatial catalog tables: This is only an internal change. Now the catalog is hosted along with the Data Observatory subscriptions. This change decouples the Analytics Toolbox location from the Data Observatory location, providing more flexibility for future developments.

Module statistics

Fix

Module retail

Fix

  • Fix bugs in kring decay procedures: KRING_DECAY, KRING_DECAY_GRID. These procedure are used internally by other procedures. They work finding cells that are within the K-Ring of each cell in a grid, and assigns a weight based on the distance. This helps model changes in a variable across neighboring cells.\

Fix

  • We have applied some fixes to the CREATE_ROUTES function so the metadata column can be successfully created and informed.

Module data

New

  • We have added the new procedures DATAOBS_ENRICH_POLYGONS_WEIGHTED and DATAOBS_ENRICH_GRID_WEIGHTED. They allow users to enrich polygons or grids based on spatial indexes (e.g. H3, Quadbin) with features from Data Observatory subscriptions by taking into account the ratio of a specified feature between the intersected and original areas in a way to weight the contribution of each feature in the enrichment. Note that the original methods only use the geographic area of intersection for this weight.

Fix

  • We have updated the GRIDIFY_ENRICH procedure so the default value for the “decay” function is taken into consideration.

Module tiler

New

May 5, 2023 (v1.3.0)

Module statistics

New

  • Set of procedures to compute Area of Applicability of a model built with BigQuery ML:

    • AREA_OF_APPLICABILITY: This procedure computes the Area of Applicability (AOA) of a Bigquery ML model. It generates a metric which tells the user where the results from a Machine Learning (ML) model can be trusted when the predictions are extrapolated outside the training space (i.e. where the estimated cross-validation performance holds).

    • ENV_BLOCKING: This procedure derives cross validation (CV) folds based on environmental blocking.

Fix

  • We have added a new mandatory parameter called correlation_var when scoring_method = FIRST_PC in the CREATE_SPATIAL_COMPOSITE_UNSUPERVISED

  • We have improved the management of temporary tables in all procedures to compute spatial composites (scores)

April 4, 2023 (v1.2.0)

Module statistics

New

  • We have released a new set of procedures within the statistics module to enable users to create spatial scores (also known as composite indicators or indexes) derived from a combination of different features. We have included 3 different procedures:

Module lds

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.

Fix

  • GEOCODE_TABLE now supports null values in the input address column, ignoring them when running the geocoding process to provide results only for the informed addresses.

March 7, 2023 (v1.1.0)

Module raster (beta)

Improvement

Note

The raster module of the Analytics Toolbox for BigQuery v1.1.0 will work only with raster-loader v0.3.0, which pre-computes and stores metadata in the raster table and homogenizes the generic/quadbin raster table format. So, if you update your Analytics Toolbox version to the most recent v1.1.0, please ensure you are using the raster-loader v0.3.0.

  • We have made the RASTER_GETMETADATA faster by retrieving metadata from the table and avoiding creating again the original table.

  • We have improved the RASTER_ST_GETVALUE by removing pixel_geog column and cluster results by quadbin in the quadbin raster format.

  • We have enhanced the RASTER_ST_GETVALUE_FROM_TABLE outcome by preserving the input columns, renaming centroid_quadbin_block and centroid_quadbin_pixel to block_quadbin and quadbin, clustering the results by quadbin in quadbin raster and removing few non-informative columns (e.g. geog and myoffset).

Module cpg

New

  • We have released a new set of functions to enable users to perform the merchant universe matching analysis. It includes 2 different functions, UNIVERSE_MATCHING which performs a fuzzy match between two different POI datasets based on location and name similarity (i.e. one dataset should include current merchants and the other one the complete universe of all potential merchants), and UNIVERSE_MATCHING_REPORT that generates report-like tables summarizing market penetration based on the results of the UNIVERSE_MATCHING analysis.

Fix

Module lds

Improvement

  • From this version, we support line break (\n) and other escaped sequences in addresses in GEOCODE_TABLE.

January 31, 2023 (v1.0.0)

Routing module (beta)

Improvement

  • New enhanced version of the routing module with procedures ROUTING_MATRIX to calculate origin-destination matrices and ROUTING_ISOLINES to compute isolines around a set of locations, both supporting multiple transportation modes (car, bike, and walk). These new functions run on top of CARTO’s road network (derived from OSM segments) that is available as a public subscription in the Data Observatory. Please note that these improvements imply breaking changes with the previous version of the routing module.

Module retail

Fix

Module statistics

  • 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. Please note that these improvements imply breaking changes with the previous version of the CREATE_ISOLINES functions.

  • Added new confidence/relevance metadata to the results of the geocoding function GEOCODE_TABLE. Please note that this improvement has implied breaking changes with the previous versions of the GEOCODE_TABLE and GEOCODE_REVERSE_TABLE functions.

Module cpg

New

  • New FIND_SIMILAR_LOCATIONS function to the CPG module, that allows users to identify which locations (e.g. merchants, stores) are more similar to a chosen location (e.g. top performant) based on the characteristics of their surrounding areas (or trade areas).
