Hi Jayanta, Thanks for the reply. Ive jotted some answers to your Q below.
Could you explain the "non-cartographic" nature of the contours? I was hoping for contours that look like the attached screenshot of wellington city (image on the right). i.e not so many islands and odd shapes as in mine. Possible?
What is the cell-size of the DEM? 1,1
In Focal Statistics, did you use the following parameters?
Statistics_Type = MEAN. Yes
Neighbourhood = 3X3. Yes
Try using 5X5 or 7X7 for more smoother effect. But the cell values will become more diluted. The attached screen shot, (image on left) shows the outcome with the 7x7 = similar result.
I also tried the fill option and the result remains identical. Am i incorrectly doing the order of operations here? i.e With focal statistics I have been imputing the DEM then applying the contour operation to the new layer - focal statistic DEM.. if that makes sense.. Likewise with the fill - I used the DEM as the input raster then applied contours to the modified raster.
Thanks again!
Simon
