A) the procedure of combining one or more data ranges into a new data range to create a new data layer
B) the procedure of establishing a relationship between two spatially correlated environmental variables
C) the procedure of estimating values at unsampled locations within an area covered by an existing set of discrete observations or samples
D) the procedure of determining which sampled points lie within the boundary of an area feature

Question

Quizplus · Accepted Answer

Spatial interpolation is the procedure of estimating values at unsampled locations within an area covered by an existing set of discrete observations or samples. It involves using mathematical algorithms or statistical models to estimate unknown values based on known values at nearby locations. This is commonly used in GIS and remote sensing to create continuous surfaces or maps of environmental variables such as temperature, precipitation, and elevation. Options A, B, and D do not accurately describe spatial interpolation.
