I am working on the damages made by the typhoon Haiyan. I use QGIS 2.0 with extensions and toolbox, and MapInfo. I have vectors, rasters of the place.
I want to map the flood area along the coastline with analyze of the height of water. The picture below shows a result approaching what i would like to obtain
Beside i have a set of 70 points, with long/lat, area inundation, height of water
that are represented on this map
I suppose that a Satellite image has been used to get the points.
My questions are:
- is it possible to represent the areas of inundation with the attributes in the table?
- If no, what is the method they could have used ? (may be not easy to guess it!)
- If yes, what is the method to proceed?
Anyone has an idea ? Thanks a lot for your help:)
