Problem Zonal Classification and Contour Interval

Recommended Posts

I'm trying to use the zonal classification to export my data (waterdepth "WSPL_max - elevation" from hydro_as) to get a shape file.

I want get a defined contour interval:

0.01-0.2

0.2-0.4

0.4-0.6

0.6-0.8

0.8-1

1-1.5

1.5-2

2-3

>3

For this purpose i defined in the zonal classification the following "criteria list":

Wassertiefen_HQ30: between 0.01 and 0.20

Wassertiefen_HQ30: between 0.20 and 0.40

Wassertiefen_HQ30: between 0.40 and 0.60

Wassertiefen_HQ30: between 0.60 and 0.80

Wassertiefen_HQ30: between 0.80 and 1.00

Wassertiefen_HQ30: between 1.00 and 1.50

Wassertiefen_HQ30: between 1.50 and 2.00

Wassertiefen_HQ30: between 2.00 and 3.00

Wassertiefen_HQ30: greater than 3.00

The process is beeing started but it deletes the duplicate node points an verticts. So in my new map there is no data.

If i try it with only one criteria - it works and i can export it to a shp-file.

So do i have to export every single contour interval??? I can't afford this time!

Thanks for your help!

P.S. Sorry for my english.

Perhaps we need to expand the documentation of this tool. The tool is setup to identify specific zones that match a list of criteria.

It seems that you are trying to define zones for distinct criteria at the same time. Therefore no zones satisfy all the criteria you have specified. It appears that you want to define a series of zones, each with a single criterion, and then select the option to generate the merged coverage.

You indicate that you can't afford the time to process each criteria independently. Is that because processing one takes too long or because you want to do this over and over again with multiple datasets?

Let me know if I am understanding you correctly and we can look for a solution to you process.
