What is an overlay analysis?
टीपा लिहा
उत्तर
Overlay Analysis Operations is the hallmark of GIS. An integration of multiple layers of maps using overlay operations is an important analysis function. In other words, GIS makes it possible to overlay two or more thematic layers of maps of the same area to obtain a new map layer similar to the sieve mapping, i.e. the overlaying of tracing of maps on a light table to make comparisons and obtain an output map.
