hello everyone, i dont know if anyone is familiarized with spatial analyst courses from ESRI but right now im trying to make some exersises that were made for arcgis 9.3 like making a raster from a selection (this is in the second chapter) ussing raster.field worked in earlier versions but now i dont know how to do it to get the same results as in the earlier version (i almost solved this by using the extract by atribute but not with the same results and the questioning continues... have someone tryied to make this excersices with the arcgis 10.?
There are some slight syntax changes from 9.3 to 10. There is also the ability to carry out many of these processes with the Python window. Please give an example of the statement that is not working and I'd be glad to look at it.
in earlier versions you just write layer.attribute and then just with that you were able to create a raster based on that attribute only now this sintaxys gives trouble, for example ersoil.Soil_Ph to calculate only that field or if i want to add for example ersoil.Soil_Ph + ersoil.Soil_Ph2 what would be the sintaxys. thnx 4 the answers!
I thought I had put this in my post, but looks like I forgot. You can use the Lookup tool, to create a new raster based on a field, and then use that in the Raster Calculator.
Thnx Patrick! ok ive tried that two, but what happens if i have to make a add opperation like the one i mentioned earlier e. soil.Ph + vegetation.Ph can i do this on the calculator or do i have to make more steps?
thnx for your answers ive been playing with this and discover alternative ways, unfortunately the calculator is not as powerfull as before you have to ake some steps more to reach the same results as before. 😞
