Tanja -This does work, I use it in my ESG Utilities Wizards (US$279), one of which includes
1. I need to decompress hundreds of ecw files. I found a command line program called import_raster_trans, but it doesn't seem to work.
How can I use this command line in a batch file and what is the correct way of specifying the input/output file directory ?
a wizard that can batch import (decompress) ECW files. If you want to write your
own script, you'll need a fair knowledge of programming basics. It's a bit complicated to
explain how to write the script without actually doing it. Basically you need to ask for
one file or the input dir, generate a list of ECW files in the dir using the "listdir" command,
then recurse through import_raster_trans for each file (using the "system" command to
run the program from within the script). You should give it the full path names
of the input and output files and specify a file with a .ers extension as the output, e.g:
import_raster_trans C:\ECW\Image01.ecw C:\ERS\Image01.ers
2. I have used the Gridding Wizard to create a grid from my XYZ points. Now I would like to relate certain colours to certain elevation values.Does this mean you want to display an exact range of values for each color
How can I achieve this ?
(i.e., 0-100 red, 101-200 yellow, etc.)? If so, you can use Classification layers
to do this. There is an example algorithm in the examples/Miscellaneous/
Templates/Common folder names "Color_coded_intervals.alg" that you can
use as an example. A threshold formula is used in each layer to define the
interval, and the color of each layer is controlled by the color button on the far
right side of the process diagram.
