Abstract:
This paper presents the drainage network extraction of South American region using Shuttle Radar Topography Mission (SRTM) data set with 90 meters of horizontal resolution. Using different thresholds, the user can generate different drainage networks. The Height Above the Nearest Drainage (HAND) procedure was applied for each drainage. HAND determines the variation of relief in relation to the nearest drainage segments of each point, considering a regular grid structure representing the relief of the study geographic region. HAND is used to determine the areas with greatest potential for flooding. Results for South American region were shown illustrating the potential use of HAND process. The main benefit of this work is to show the viability of using this tool to study and simulation areas that can be flooded by natural processes or anthropic actions.
