Inverse Distance Map


This map shows the precipitation grid of Idaho using an inverse distance interpolation method. IDW is an interpolation method that lays a grid over the points we already have data for (the control points) then interpolates the values of the grid by taking into account the values of nearby control points. Like the last time I exported a map as a jpg the border of the map is not showing. I have no idea why this is.
