Abstract
Methods and systems for extracting and reviewing landcover feature data are provided. An example method involves accessing geospatial imagery covering a geographic area and landcover feature data extracted from the geospatial imagery, subdividing the geospatial imagery into a grid of image tiles, assigning landcover feature data review technicians to review the image tiles and associated landcover feature data through a landcover feature data review platform, and receiving revised landcover feature data that modifies the landcover feature data.
Claims20
A method comprising:
- accessing geospatial imagery covering a geographic area;
- extracting landcover feature data from the geospatial imagery that represents one or more landcover features in the geographic area;
- accessing confidence data associated with the landcover feature data that indicates a degree of confidence that the landcover feature data accurately represents the landcover features;
- subdividing the geospatial imagery into a grid of image tiles, each image tile covering a subset of the geographic area, and, for each image tile, associating the image tile with a subset of the landcover feature data that represents the landcover features covered by the image tile;
- determining a set of image tiles to be assigned for data review, the determination, for each image tile, based on an evaluation of the confidence data associated with the landcover feature data for the image tile;
- for each image tile to be assigned for data review, assigning a landcover feature data review technician to review the landcover feature data with reference to the associated geospatial imagery through a landcover feature data review platform;
- and
- receiving revised landcover feature data from the landcover feature data review platform that modifies the landcover feature data corresponding to one or more landcover features.

A method comprising:
- accessing a landcover feature data review platform;
- receiving, through the landcover feature data review platform, an assignment for a landcover feature data review technician to review landcover feature data associated with an image tile, and receiving access to the landcover feature data and geospatial imagery associated with the image tile, wherein the landcover feature data was extracted from the geospatial imagery to represent one or more landcover features depicted in the geospatial imagery;
- and
- generating, through the landcover feature data review platform, with reference to the landcover feature data and associated geospatial imagery, one or more modifications to, or notifications regarding, the landcover feature data.
