Can anyone suggest best Suitable Algorithm for Digital Elevation Model Generation? Currently I am working on Literature survey of DEM creation so i need to show comparison of 3-4 Algorithmic Methods used to create DEM & Best suitable method among them.
There is no "best Suitable Algorithm" for what you want because it depends on the result you want to get
Each method has its advantages and disadvantages depending on the result you are trying to reach.
So, select algorithms that match the needs of your project and whose strengths match the topography of your study area. Ideally, a different algorithm should be developed for each project area and having more than one available for use will allow for a comparison of results.
