Hello, could you provide a example template that we can submit results or an API to transfer our image into the corresponding format.
Thank you very much.
Hello,
The required format for the solution is a csv with 4 columns
See below for a snippet:
ImageId: The Image name of the chip without the extension or the Image Type description.
i.e. AOI_2_Vegas_img2144
BuildingId: The Building Id. This is a number starting at 1 and increasing in count for each polygon. If the Image is empty set the building id = -1
PolygonWKT: This is a WKT String of the Polygon Describing the building footprint. (https://en.wikipedia.org/wiki/Well-known_text) If this is an empty chip set this to "Polygon Empty"
Conf: This is the confidence ranking of the polygon.
An example of how to generate the PolygonWKT is to use https://rasterio.readthedocs.io/en/latest/topics/features.html#extracting-shapes-of-raster-features
