Description
This tool allows collecting successively cell-wise statistical information from grids by subsequent calls. The targeted data sets, particularly the histogram, should have been created with 'Build Statistics for Grids' tool. The collected information can be used consequently as input for the 'Evaluate Statistics for Grids' tool. These three tools (build, add, evaluate) have been designed to inspect a large number of grids that could otherwise not be evaluated simultaneously due to memory restrictions.
