For geospatial data, Tamr Core supports the Simple Features ISO 19125 standard with a single, heterogeneous layer. This standard is used by geographic information systems and specifies a common storage and access model of geometry types.
Tamr Core supports the following geospatial data types in GeoJSON format:
pointis a longitude/latitude pair, where both of the geographic coordinates are specified in WGS84.
lineStringis an array of point coordinates, such as
[100.0, 0.0], [101.0, 1.0].
polygonis a linear ring representing the exterior, and zero or more interior linear rings representing holes. Each linear ring is defined as an array of points where the first and the last points are the same.
Transformations support these geospatial data types. See Working with Transformations for Geospatial Data.
