Thank you for the quick reply. I have ArcGIS in hand. Let me check HEC-HMS and will report back how I do. NOt very clear to me right now, how do you model which area gets flooded, since I think not every area under the waterheight will get flooded, only area close to the river/bassin, and even then, waterlevel is not getting as high as where the gauge is.

Hi All,
I would like to model floods and evaluate damages it could have had on crops in a particular area. The problem is however, I do not have clue where to start and what processes are.
So far, the dataset I have :
- Digital Elevation Model (DEM)
- Land use map (with crop types)
- measure from gauge : water height (in meter) and debit (in cubic meter per second)
so, from there, where I am going, any other datasets needed?
Thank you
Hi all, I came accross something and I am stuck, need your help :
- I have a point shapefile
- I also have a raster file
I want to append the raster pixel value into the shapefile attributes (equivalent to append in shapefile/shapefile, but I don't know how with raster)
I am using arcGIS, but also erdas (thanks lomex)
thank you
Hi all,
it is too late now but it may be helpful to others
- save the signature file
- change the image association from the signature editor, edit menu
- the .sig file is now associated with the image to be classified
