Thoughts - Creating Contours From SRTM Data Using Global Mapper
Eiao Island - SRTM/DEM With Contours
Eiao Island - Contours 50-Meter Intervals
This was going to be a "How To" post, but I am not ready to tell you "How To" yet. I am still figuring all of the intricacies that apply to creating contours from Global Mapper. Needless to say, it is a fairly simple process. Load the SRTM DEM/HGT file, determine contour criteria, select "Create Contours" from the File Menu and you have created a series of contours.
Obviously, the contours are only as good as the underlying data (SRTM). As I work more with the data and how it foots with Landsat and Google Earth 1-Meter Imagery, I will gain greater confidence in creating a new layer of information to be included with some of my high islands.
I think it could be a great addition to my EVS Islands. Just have to wait and see.
Enjoy!

Does any GIS staff has experience with many types of visual analysis, can you tell me about some who can help us
