comment How to convert raster to polyline in QGIS?
Just run that and it crashed. I will download grass itself and try in GRASS. I was trying version 7 on a different machine and just about every function in GRASS was crashing so I am hoping that in Windows 7 i will have better luck. So far my QGIS/GRASS experience is such - constant crashing.

comment Methodology for creating accurate drainage networks (and catchments) from high resolution LiDAR DEM?
Just wanted to say that this is great! Running some preliminary tests with a colleague of mine on our Lidar datasets and early results are looking very promising. Amount of features and parameters and the ability to even add some cartographic touches is great. Results are matching up with actual streams. Also finding out just how outdated the ESRI algorithms are - unchanged since the mid 80s. That explains a lot. Thank You!

Very Interesting! You are able to produce the same error I am seeing using ESRI tools. This leads me to believe that the ESRI algorithm is simply not capable to deal with high resolution data. This pretty much answers the question. Thanks for the visuals - amazing! I have next to no experience using GRASS tools for watershed/drainage analysis. I would greatly appreciate if you could point me to a basic "how-to" tutorial.

Fair enough, wanted to double check before I write my own. Can you please make your comment an answer?

Did you turn on the extension in Customize -> Extensions in both ArcMap and ArcCatalog?

Do you have the 3D analyst extension? If not you can't create terrain dataset or TIN.
