==Resize==
'''"-resize<factor>"'''<br>
Resize the grid based on the factor above. The factor must be an integer (greater than 1). The output grid has the same origin (lower left) coordinates as the input grid. The new cell size is the factor times the old cell size. For example if a -resize5 is used on a 2m resolution grid the output grid will be 10m. For processing the grid three options are available:
===Average (default)===
This is the defualt processing method, which can also be specified with the '''-rm_avg''' (resize method - average) input flag. When processing for each tile in the new grid, the average of all non-null values in the input grid is taken. For example with a resize factor of 5, the 25 values in the input grid are averaged.<br>
Example:
*Creates a new 10m DEM based on the the 2m DEM using an averaging approach.<br>

===Minimum===
Alternative processing method for resize, specified with the '''-rm_min''' (resize method - minimum) flag. At each output grid the values isare the minimum of the values in the input grid.<br>
Example:
*Creates a new 10m DEM based on the the 2m DEM using an minimum approach.<br>
Line 113:
 
===Maximum===
Alternative processing method for resize, specified with the '''-rm_max''' (resize method - maximum) flag. At each output grid the values isare the maximum of the values in the input grid.<br>
Example:
*Creates a new 10m DEM based on the the 2m DEM using an maximum approach.<br>
