My task is to calculate the area available for specific plant species in a natural reserve that has been reconnected to the tidal influence.
First step is to create an inundation map for a natural reserve. I have a height map in .dxf format (annotation,point, polyline,polygone and multipatch layers). I can see the height of the points in the attributes layer. I have available the data (for one year) for the tide levels from a connected tide gauge for the fluctuating water level. I'm now combining this with the plant preferences for inundation time. I expect to get a result like for species 1 the height between 1.5 an 1.7 meter is suitable, for species 2 between 1.7 and 1.8 and so on.
How do I implement this in the map and find the total suitable area for each species? I am running Arcgis 9.3 with the Spatial Analyst and 3D Analyst extensions.
