Data Quality

Lineage:1 ha grids of all known gamba grass presence within the NT Weeds dataset, created using their latitude and longitude rounded down to 3 decimal degrees.

Positional Accuracy:Original presence points positional accuracy is based on collection method. See NT Weeds Dataset metadata.

Attribute Accuracy:Attributes are assigned based on analysis of presence and absence points locations and dates. See NT Weeds Dataset metadata.

Logical Consistency:Grid polygons are single part, with top left corner lat/long at 3 decimal places (0.001) and dimensions of 0.001 east and 0.001 south.

Completeness:Completed
