Geocoding: Longitude and Latitude by Address
Geocoding takes an address, then translates it to a location on a map. It changes an address to lat long coordinates (latitude and longitude).
Raster Resampling for Discrete and Continuous Data
For raster resampling in GIS, you can use bilinear and cubic convolution for continuous data as well as nearest neighbor and majority for discrete data.
What Is Geographically Weighted Regression (GWR)?
Spatial regression is used to model spatial relationships. Regression models investigate what variables explain their location.
