Import

When you import Polygon annotations via the Model-assisted labeling or Import ground truth workflow, your JSON file must contain the following information for each Polygon.

Parameter

Asset type

Required

Description

uuid

Image

Tiled imagery

Yes

A user-generated UUID for each annotation. If you import an annotation to a Data Row and there is already an imported annotation with the same uuid on that Data Row, the latest import will override the previous one. The uuid must be 128 bits (32 characters). The following formats are supported:

  • A0EEBC99-9C0B-4EF8-BB6D-6BB9BD380A11

  • {a0eebc99-9c0b-4ef8-bb6d-6bb9bd380a11}

  • a0eebc999c0b4ef8bb6d6bb9bd380a11

  • a0ee-bc99-9c0b-4ef8-bb6d-6bb9-bd38-0a11

  • {a0eebc99-9c0b4ef8-bb6d6bb9-bd380a11}

schemaId

Image

Tiled imagery

Yes

The ID of the schema that contains all of the information needed for rendering your annotation.

dataRow.id

Image

Tiled imagery

Yes

The ID of the Data Row where you want to attach the imported annotations.

polygon.x

Image

Tiled imagery

Yes

x-coordinate for a single point on the Polygon annotation. For Tiled imagery, this value is the longitude.

polygon.y

Image

Tiled imagery

Yes

y-coordinate for a single point on the Polygon annotation. For Tiled imagery, this value is the latitude.
