Información adicional
The expression below won''t work in python, because map algebra take raster object as input, while "Random1.tif" would be treated as string but not raster in the expression ""Random1.tif">0.1". >>> Con(("Random1.tif" > 0.1),"Random1.tif",Con(("Random2.tif">0.1),"Random2.tif",0.1)) In stead, defining a raster object first for this layer, then the complex expression should work. >>> rasob = arcpy.sa.Raster("Random1.tif") >>> outras = Con((rasob > 0.1),"Random1.tif",Con((rasob> 0.1),"Random2.tif",0.1))Solución alternativa
Using the syntax containing the <where_clause> parameter from the following help resources, it is still possible to create complex Conditional expressions. 10.0: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//009z00000008000000.htm. 10.2: http://resources.arcgis.com/en/help/main/10.2/index.html#//009z00000008000000. 10.3: http://desktop.arcgis.com/en/desktop/latest/tools/spatial-analyst-toolbox/conditional-evaluation-with-con.htm.Pasos para reproducir
