Hi I’ve got an issue with Ras mapper, unfortunately when i come to digitise the river string RAS mapper just hangs on me and freezes.
I’ve tried loading an example dem from the tutorials and don’t have a problem.
When I expand the geom tree for the river i can add flow lines etc but as soon as I try to add the river string it freezes. I can also add x sections without a problem.
I’ve set the projection and the dem is 12,000kb so not sure what I’m doing wrong.
Can anyone offer some advice please?
Regards
Paul
Paul, I’ve never heard of that issue before. Not sure what is going on. The only thing I can suggest is to keep trying, but try differently. What I mean is try to draw your river again, but see if there’s a different sequence of mouse clicks or whatever that makes it work. Kind of a long shot, but sometimes you just have to try to “trick” RAS. If you can’t get that to work, you should send a bug report to HEC about it.
I saw your response to the topic previously posted but i will respond here. I would digitize a reach in ArcMap and try importing it into RAS Mapper just to see if the process works. If this doesnt work, try multiple things such as building a new model, adding a new geometry with a different name. Make sure your reach being imported has a simplified geometry. Meaning, if your reach has 5 million vertices then of course it will hang up on you. Try simplifying your input reach in a GIS platform then reimport within RAS
