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
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.
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
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
