hello im new here,
so i have problem with my modeling. now im working to modeling migration and accumulation of hydrocarbon. i have got the model builder from someone who has similar project with me. i tried to follow the model builder but have problem when i used "raster to polyline" tools (see the attachment), it became a grid-line. first i think that the problem is my data but when i tried with another data the results still same, it became gridline. can anyone help me with this problem?? thank you
Looking at the layers, I feel you are looking to delineate the stream network.
Are you looking for the polylines of Stream Network? In that Case, you could follow these steps .
1. Add a DEM
2. Fill Sink
3. Flow Direction
4. Flow Accumulation
5. Con Tool (Optional; To delineate appropriate Stream Network)
- Select Flow accumulation as input conditional raster - Set 1 as constant value - Expression: Value > <a threshold pixel value>
6. Stream Link
7. Stream to Feature
See this link Identifying stream networks—Help | ArcGIS Desktop
why are you using 'raster to polyline' if you don't want lines? Are you looking for a polygon? If so, you would have to use the 'raster to polygon with a cell size large enough to close up the space between your polylines.
