Geospatial object geometry extraction from imagery

A method, comprising:

• supplying a plurality of truth pairs to a first machine learning algorithm and a second machine learning algorithm, each of the truth pairs including a truth image and a truth shape image, the truth image having first pixel values depicting a structure and second pixel values depicting a background of a geographic area surrounding the structure, the structure having an outline, the truth shape image having third pixel values indicative of a truth shape indicating the outline of the structure, wherein the truth image and the truth shape image have a same pixel resolution;
• generating a synthetic shape image of the structure from the truth image using the first machine learning algorithm, the synthetic shape image including pixels having fourth pixel values forming a synthetic shape of the outline of the structure;
• passing the synthetic shape image of the structure from the first machine learning algorithm to the second machine learning algorithm;
• comparing the synthetic shape against a truth shape from the truth shape image;
• and
• providing feedback from the second machine learning algorithm to the first machine learning algorithm to train the first machine learning algorithm to minimize any differences in the synthetic shape and the truth shape.

A method, comprising:

• receiving, with one or more computer processors, an image of a structure having an outline, the image having pixels with first pixel values depicting the structure and second pixel values outside of the structure depicting a background of a geographic area surrounding the structure, and image metadata including first geolocation data;
• generating a synthetic shape image of the structure from the image using a machine learning algorithm, the synthetic shape image including pixels having pixel values forming a synthetic shape of the outline, the synthetic shape image having second geolocation data derived from the first geolocation data, wherein the synthetic shape of the outline is a vector outline of the structure;
• mapping, with the one or more computer processors, the vector outline onto the image of the structure, based at least in part on the first and second geolocation data;
• and
• changing the second pixel values of the image so as to not depict the background of the geographic area surrounding the structure.
