Load the shapefile with raster::shapefile This shapefile is for the Laurentide Ice Sheet, which covered large portions of North America 18 thousand years ago during the Last Glacial Maximum. It contains no unique data, only an index of record offsets. Developed by Esri, shapefiles are now an open format and is a popular option for data transfer. Filter and Select Input Shapefile to New Output Shapefile Like ogr2ogr CLI¶ The ogr2ogr command line tool is an easy way to filter, reproject and trim columns in a shapefile. But it’s not just about plotting reference maps per se; it’s about plotting the reference map over some sort of raster or other data layer, like you would in a GIS application. I tried a couple methods, but both are near logic-less and either run an infinite loop or don't run. As a result you get a geospatial object (my_spdf here) that contains all the information we need for further mapping. So first, let’s look at migrating shapefiles into the geodatabase. com is a data software editor and publisher company. 3 Choropleth mapping with ggplot2.
