in spatial analyst extension, i am using hydrology tool. my goal is to extract stream network or stream segment from the given raster data, that i have in tiff format. I am applying CON tool to the output of flow_accumulation tool, for obtaining the stream network, am i doing right ?. after that i am applying stream to feature tool to the output of CON tool, to obtain the output in vector line format but still this output is shown as points not as line.
