Description
Northern Territory gamba grass class A eradication register 10 km grids.
0.1 x 0.1 degree (approx. 10 km x 10 km) grids of gamba grass eradication status (Active, Monitoring or Locally Eradicated) as of June 2025.
Status assessed annually (1/6 to 31/5) since 2008 (1/6/2007 - 1/5/2008). Scale up of 1 km grids. If there are any active 1 km grids, 10 km is active. If no active, but at least one monitoring 1 km grid, 10 km grid would be monitoring. If no active or monitoring 1 km grids within 10 km grid, but there is locally eradicated, then 10 km grid would be locally eradicated.

Data Quality
Lineage:10 km grids of all known gamba grass presence within the NT Weeds dataset, created using 1 km GGMU grids rounded down to 1 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 1 decimal places (0.1) and dimensions of 0.1 east and 0.1 south.
Completeness:Completed
