Common data types

Datetimes

Datetime parameters are expressed in ISO-8601 format and in the UTC (Z) timezone, unless otherwise specified in the documentation.

    "created_at": "2024-04-20T23:14:50.2891923Z"
}

UUID

A UUID (universally unique identifier) is a string, conforming to this regular expression: ^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}$.

    "workspace_id": "a6fcd8e0-b2cf-4a22-b1cd-ef226abc196b"
}

Coordinate reference systems

Coordinate reference systems (CRS) are a standardized method of describing different locations on Earth's surface. The choice of CRS depends on the environmental factors and the region where the data was collected. Therefore, providing a CRS will be important if you are handling region specific data.

Evo supports ESPG codes and OGC WKT v2. ESRI codes must be converted to OGC WKT v2. If an EPSG code is provided, it must be for a coordinate reference system with a length unit type (e.g. metre, or foot).
