in raster calculator how you take Flow accumulation > = 10,000 ? can you please tell me how to decide this 10,000 ? i did'nt get the answer anywhere

[@beesalg618]

1 percent of highest value of flow accumulation which is 1.23*10^6.

Can I create a drainage density map from an available stream shapefile? So I don't to derive stream network based on DEM since I already have a shapefile of stream network in my study area.

[@geotechstudio]

If you have necessary parameter determining drainage density in shape file you donot need to create stream network

I have downloaded the SRTM map of my area but when I load the map in ARC Gis I cannot see anything. It is completely grey in colour. It has both upper and lower values as zero. What to do?

[@geotechstudio]

Download again and try it once

[@TejassKadam]

I downloaded the SRTM 1 Arc-Second Global map from USGS. Can you suggest which map should I download?

[@geotechstudio]

Its just threshold value created for creating suitable drainage channel or stream channel.

What is the meaning of 10000 in raster calculator? Thank you

[@geotechstudio]

threshold value

Hello Sir. I already have the shp but there is no grid code in the attribute table. So I will not get the density?

[@geotechstudio]

Gridcode should be there otherwise it cannot be done.
