Interpolation Analyst

In field survey or data gathering, mostly you will survey at some sample locations instead of visiting each location due to the resource and budget. Thus, through the sample data collected, we still can not understand the information of the entire area.

Interpolation Analyst will estimate the other known values by the sample data. That is, to estimate the other unknown points in space based on one point. It is suitable for analyzing rainfall, noise and pollution distribution.

In SuperGIS Spatial Analyst 3, it provides IDW and Trend to estimate the successive surface by multiple samples.

Interpolation Analyst includes two methods:

❖IDW

❖Trend
