Efficient Calculation of Distance Transform on Discrete Global Grid Systems
ISPRS International Journal of Geo-Information, 2022 Geospatial data analysis often requires the computing of a distance transform for a given vector feature. For instance, in wildfire management, it is helpful to find the distance of all points in an area from the wildfire’s boundary. Computing a distance
