  "Description": "Rasterize polygon, line, and point geometry without\nmaterializing any pixel values. For polygons it computes exact\ncoverage fractions for polygon-grid intersections, returning\nsparse tables: run-length encoded interior cells and\nindividually weighted boundary cells. The scanline algorithm is\nO(perimeter) in both time and memory, using the scan line fill\nattributed to Wylie et al. (1967)\n<doi:10.1145/1465611.1465619>. Exact coverage fractions use the\n'exactextract' algorithm by Daniel Baston, vendored from the\n'exactextractr' package\n<doi:10.32614/CRAN.package.exactextractr>. Derived from the\n'fasterize' package by Noam Ross.",
