stream network is showing as set of points, how to change it to line network ?

[sandeepgarg1]

I have raster stream network, which is showing as set of points and after converting it polyline (using raster to polyline tool), it is still showing the network as set of points.

image? show what you mean

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.

Im assuming that you have a raster DEM to start with. Run Fill, Direction, then Accumulation. From accumulation you can manipulate the raster by changing symbology or using raster calculator (if you have a large range of accumulation Log(10)accumulation will create a much more visible stream network. From here you can reclassify so that areas that aren't in the stream network are given values of NoData and areas within the stream network have a value of 1. (go into symbology and set it to classifications, change the number of classifications to 2 and mess around with the placement until you have found what the classifications capture the stream network). From here you can use the stream to feature.

Hope this helps
