Introduction to GIS and Remote Sensing with R

Learn to import and visualize spatial data by loading a shapefile with the sf package in R, then plot and interact with a five-layer Congo National Park dataset using mapview.

Learn to read and merge multiple shapefiles in R for GIS tasks. It demonstrates listing shapefile paths, applying read to each file with map, and exporting the merged data.

Learn to convert a csv to a shapefile in r by loading packages, reading the csv, specifying x and y coordinates, and creating a point shapefile for locations in chile.

Join an Excel sheet with a shapefile to map population across communes in a Chile region by aligning column names and performing a shapefile join in R.

Filter points that fall within a polygon, use contains to identify their indices, then visualize and export the selected results in R.

read a raster from a bucket, use the roster function to read the raster, inspect layer dimensions, number of columns, resolution, extent, and values, then plot the raster for visualization.

Learn to convert a polygon shapefile to a raster by setting a 30-meter resolution, matching the extent to the shapefile, and assigning polygon areas to raster values.

Convert raster data to polygons in R by loading packages, applying the raster to polygons function with dissolve = true, and desegregate to refine boundaries.

Learn to create a raster mosaic from overlapping rasters using the mosaic function, layering two rasters and adding a third, then export the final mosaic as a raster file.
