Spatial Operations
Components to compute operations and measures on geometries/geographies, or to alter geometry/geography size or shape.
Description
This component creates a new table with a distance matrix computed for the geometries contained in an input table.
The output table contains three columns: 'id1', 'id2' and 'distance'.
Inputs
Source table [Table]Geo column [Column]Id column [Column]
Outputs
Result table [Table]
Description
This component creates a new table with an additional column containing the area of the geographies in the input table. This only applies to the case of polygon geographies. For other geography types, the value will be zero.
Inputs
Source polygons table [Table]Geo column [Column]
Outputs
Result table [Table]

Description
This component adds a new column with a buffer of the original input geography.
Inputs
Source table [Table]Geo column [Column]Distance [Number]
Outputs
Result table [Table]
External links
Description
This component creates a new table with a new column containing points representing the centroids of the original input geographies.
Inputs
Source table [Table]Geo column [Column]
Outputs
Result table [Table]
External links
This component requires the CARTO Analytics Toolbox installed in the chosen connection to build the workflow.
Description
This component creates a new table containing a single row with the concave hull of geographies in the input table. The concave hull is stored in a column named 'geo'.
Inputs
Source table [Table]Geo column [Column]Max edge (km) [Number]
Outputs
Result table [Table]
External links
Description
This component creates a new table containing a single row with the convex hull of geographies in the input table. The convex hull is stored in a column named 'geo'.
Inputs
Source table [Table]Geo column [Column]
Outputs
Result table [Table]
External links
Description
This component calculates the minimum distance between geographies of an input table and those of a second table.
It adds two new columns: 'nearest_id' and 'nearest_distance'.
Inputs
Main table [Table]Secondary table [Table]Geo column in main table [Column]Geo column in secondary table [Column]Id column in main table [Column]Id column in secondary table [Column]Radius [Number]
Outputs
Result table [Table]

Description
This component creates a new table with an additional 'length' column containing the length of the lines in the input table.
Inputs
Source lines table [Table]Geo column [Column]
Outputs
Result table [Table]
External links
This component requires the CARTO Analytics Toolbox installed in the chosen connection to build the workflow.
Description
This component takes a table and columns containing lines and distances. It adds a new column with points computed measuring the corresponding distance along each line.
Inputs
Source table [Table]Lines column [Column]Distance [Number]
Outputs
Result table [Table]
External links
Description
This component adds a new column containing the perimeter of the geographies in the input table. This only applies to the case of polygon geographies. For other geography types, the value will be zero.
Inputs
Source polygons table [Table]Geo column [Column]
Outputs
Result table [Table]
External links
Description
This component adds a new column containing a simplified version of the original input geography.
Inputs
Source table [Table]Geo column [Column]Tolerance [Number]
Outputs
Result table [Table]
External links
Description
This component takes an input table and creates a new one replacing its geo column by a new column containing the original input geography snapped to a grid a specified size (in degrees).
Arbitrary grid sizes are not supported. The grid_size parameter is rounded so that it is of the form 10^n, where -10 < n < 0.
Inputs
Source table [Table]Geo column [Column]Grid size (degrees) [Number]
Outputs
Result table [Table
