Filling gaps in electric grid models

A non-transitory computer storage medium encoded with instructions that, when executed by one or more computers, cause the one or more computers to perform operations comprising:

• obtaining first raster image data that depicts an overhead view of electric grid wires within a geographic region, the first raster image data including first pixel values for pixels in a first array, each pixel in the first array corresponding to a respective geographic location within the geographic region, wherein the first pixel values indicate a likelihood of presence of grid wiring at the respective geographic location;
• obtaining second raster image data, wherein the second raster image data depicts an overhead view of at least part of the geographic region, the second raster image data including second pixel values for second pixels in a second array, each pixel in the second array corresponding to a respective pixel in the first array and to the respective geographic location within the geographic region, wherein the second pixel values indicate a characteristic of the respective geographic location;
• processing the first raster image data and the second raster image data using a gap filling model that is configured to fill gaps in raster images depicting overhead views electric grid wires;
• and
• obtaining, as output from the gap filling model, third raster image data that depicts an updated overhead view of the electric grid wires, the third raster image data including third pixel values for third pixels in a third array, wherein the third pixel values indicate an updated likelihood of presence of grid wiring at the respective geographic location.

A system comprising one or more computers and one or more storage devices on which are stored instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
