topic Updated Syntax for Raster Calculations in ArcGIS Spatial Analyst Questions https://community.esri.com/t5/arcgis-spatial-analyst-questions/updated-syntax-for-raster-calculations/m-p/6479#M135 <HTML><HEAD></HEAD><BODY><SPAN>Hello,</SPAN><BR /><BR /><SPAN>I'm a current GIS student working on a capstone project at my school. For part of my project, I am doing a watershed analysis. I've been following a slightly older tutorial from '08 to do this and I recently ran into an issue that I can't seem to get around. The tutorial has me "deriving a specific watershed for each point". I've hit the point where I have to use the raster calculator. The syntax the tutorial gives me is: watershed([flowdirection], [pourptgd]). Unfortunately, this seems to be an older syntax and I can't seem to get it to work. I was wondering if anyone had suggestions about what the proper syntax would like for arc10? </SPAN><BR /><BR /><SPAN>Thanks Much</SPAN></BODY></HTML> Sat, 09 Jun 2012 16:32:04 GMT GeoffreyMarcus 2012-06-09T16:32:04Z Updated Syntax for Raster Calculations https://community.esri.com/t5/arcgis-spatial-analyst-questions/updated-syntax-for-raster-calculations/m-p/6479#M135 <HTML><HEAD></HEAD><BODY><SPAN>Hello,</SPAN><BR /><BR /><SPAN>I'm a current GIS student working on a capstone project at my school.
