Hi,

 

 

How to seperate contours based on Elevation.Ex : we have 0.5 m contours(0.5m,1m,1.5m,2m,2.5m etc...).I need 2m contours from the above 0.5m contour like(2m,4m,6m etc).

 

 Any tool is there for sepetate the contours

Hi,

 

 

If the contour features don't have elevation value as attribute, you can use the ElevationExtractor to extract z-value of each feature.

 

Then, see this similar question.

You could always start with 

 

 

- TestFilter - Filter on Elevation >= 2 (m)

 

- Sorter (Numeric, Ascending)

 

- Sampler

 

          - Sample every Nth Feature 

 

          - Use 4 (if they are every 1/2 meter apart)

 

 

 

Regards,
