Hello Jeff, thank you for the video. I have a question. When you have created the gdb in Arcgis the data are structured in Arcgis but these are organized links to the actual data that are kept on the desktop's folder. The data in folder are still not organized. Actually my question is how to organize the data - all these files with different extentions.

@jeffsun_GIS 5 ай бұрын

If I understand your question right. The gdb when you look at it outside of ArcGIS does not look organized, in fact it’s just a bunch of non sense, programming language to me. It only makes sense when you look at it in ArcGIS. Does that answer your question?

I have 2 questions here : 1. Can I use DTM file to create the flow direction? 2. Why I cannot compute the D8 flow direction type? It only show me black and white result

@jeffsun_GIS 10 ай бұрын

Does your DTM contain elevation data? Or is it simply a hillshade model. The D8 tool needs elevation to work. If it is elevation data try running the full tool on it first to eliminate any errors in it.

@shazrielimran430 10 ай бұрын

@@jeffsun_GIS It does, because I can produce contour line from the DTM file. But still, it can't create the flow direction as you did in the video.

Good video! Thx! Just bought an eTrex Legend on eBay, like new, for $15+shp. Came with original box. manual, cables etc.... not a scratch on it. It came with a serial and USB cable, but I don't think the USB can be used on this old eTrex! I'm looking forward to learning and use it! 😎😎

Yes! If you select the features you want In the geodatabase first then export it into the GDB. That should work

Hi Jeff, I am getting the same issue you were having with very small watersheds. I am not sure what you changed to get the result in 16:40. Can you please explain? I have been stuck on this for a long time. Thanks!

@jeffsun_GIS 2 жыл бұрын

Yea sometimes because the DEM may have errors in it, or your POR point may not be right on the stream, you will get those small one pixel watersheds. What I have found is that you will have to move the POR point slightly up or down the stream. Also make sure the POR point is right on the stream network line. You can use the snapping tool to make sure the point is on the stream line. I hope this helps. :)

Excellent video. Stupid question maybe, but can you confirm that all projection made 'On the Fly" carry over to the finished map layout you might then export or print? I assume this is the case but I haven't really seen a confirmation of that, and also wondering if there are any conditions where that would not be the case

From my experiences the projection has always carried over to your map layout. I’ve never had it not do that. Glad the video was useful!

Thanks for your efforts to make this amazing work. I am trying to digitize and edit houses or buildings but i am being confused regarding the type of feature class. Will i choose points or polygons to the type of feature class that represents buildings and houses?

@jeffsun_GIS 2 жыл бұрын

It depends how you want to represent them. If you are needing the area of the house or if the rooftop then you would use a polygon. If you are just wanting the location of a house you could simply put a point on top of the house. I hope this helps.
