save_poly_cells.RdSave rds files containing data frames of grid cell indices for the intersection of common SNAP spatial polygons with SNAP template raster layers. Indices are stored for two conditions: matching to all raster cell indices and matching to new cell indices based on first removing all NA-valued cells and re-indexing.
save_poly_cells(file_akcan = "cells_akcan1km2km.rds", file_ak = "cells_ak1km.rds", out_dir = snapdef()$celldir, mc.cores = 32)
| file_akcan | file name for cell index table based on the Alaska/western Canada SNAP spatial domain. |
|---|---|
| file_ak | file name for cell index table based on the Alaska "statewide" classic ALFRESCO SNAP spatial domain. |
| out_dir | output directory. |
| mc.cores | number of processors. |
invisible, writes files.
Note that this function also folds in FMO area unions from `snapgrid::swfmo` for the Alaska domain.
