Efficient Calculation of Distance Transform on Discrete Global Grid Systems

open access: yesISPRS 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

Correlation Analysis and Reconstruction of the Geometric Evaluation Indicator System of the Discrete Global Grid

open access: yesISPRS International Journal of Geo-Information, 2021
Although a Discrete Global Grid (DGG) is uniform in its initial subdivision, its geometric deformation increases with the level of subdivisions. The Goodchild Criteria are often used to evaluate the quality of DGGs.
