Spatial Features, the new derived dataset from CARTO


We are excited to announce the release of our first derivative data product providing global demographic data & POI aggregations by category.

Spatial Features, the new derived dataset from CARTO

Data is an essential ingredient for any spatial analysis; but often  before any dataset can be mined for insights  data scientists need to spend a considerable amount of time gathering  cleansing  and preparing data from a host of different sources. CARTO is committed to change this and to increase the efficiency of Data Science teams and their workflows.

A few weeks ago we announced a new release of our Data Observatory. CARTO’s spatial data platform enables Data Scientists to broaden the scope of their analysis with the latest and greatest in location datasets.

Today  we are excited to announce the release of our first derivative data product: CARTO Spatial Features; which provides global demographic data and Point of Interest (POI) aggregations by category  delivered in a common geographic support system.

Overcoming the change of support problem

The spatial data industry is booming  with new and viable data sources becoming available at an unprecedented pace. This means that data scientists are faced with the ever-present problem of how to easily blend data in multiple formats. In Spatial Data Science this is a real challenge  as datasets can be aggregated at a variety of different levels of geography.

Take  for example  a Consumer Packaged Goods (CPG) manufacturer trying to classify the areas surrounding its key retailers. Demographic data (e.g.  population  age  and income)  human mobility  road traffic data  and competitor locations–all of these variables are probably going to be expressed in different geographical scales (e.g.  administration or census regions  grids  and coordinates). With CARTO Spatial Features we have curated multiple sources to provide data in a common and consistent geographical context.

This first version of Spatial Features  available now in the CARTO Data Observatory as a premium dataset  provides demographic variables such as total population and population by age and gender  and Point of Interest (POI) aggregations in a curated set of standard categories (e.g.  retail  education  healthcare  tourism  etc.). This initial set of derived data has been generated by processing and unifying sources from WorldPop and OpenStreetMap  solving the ever-present change of support problem (COSP). The data is available globally  and offered as well on a country by country basis.

Data is available at two levels of resolution

For this first derivation  our common geographic support of choice has been the Quadkey grid or Quad Grids; a division of the Earth into quadrants (using a planar projection)  each uniquely defined by a string of digits with a length that depends on the level of zoom. In the Quad Grid system  cells at different zoom levels are fully nested in a hierarchical parent-child relationship  allowing for quick retrieval and efficient data storage. This also facilitates running spatial aggregations and visualizations on the web. Our Spatial Features datasets are available in two different resolutions  Quad Grid level 15 (with cells of approximately 1km x 1km) and Quad Grid level 18 (with cells of approximately 100m x 100m).

Spatial Features is an evolving product  and our Data team is already working on further expanding these datasets in subsequent releases with additional features including land use categorization and spatial lags such as distances to hospitals  schools  main roads etc  as well as supporting other standard grid systems such as H3 hexabins.

Access Spatial Features sample data today

In order to encourage innovation and to gain valuable feedback from real use-cases using these derived datasets  CARTO enterprise customers can now subscribe to the first version of CARTO Spatial Features datasets in the United States  United Kingdom  and Spain at no cost. These have been made available as public datasets in the Data Observatory and can be accessed free of charge.
