I am trying to extract stream raster from a flow accumulation raster using Conditional Tool in Spatial Analyst.
Here's my input:
- Input Raster: FLOWACC.tif
- Expression: Value >= 3.5
- True Raster: 1
- Output raster: Stream.tif
Error gives me invalid expression. Basically my objective is to isolate all values >=3.5 and consider them as stream raster.
I am using ArcGIS 10.2 for Desktop.
