This was extremely helpful, thank you so much. Also, 'let it rip', indeed. I say 'giver'a'go' and I think I like let it rip much better.

@MapPractical 3 года назад

Glad it helped. "Let it rip!"

That is a great video. Thank you. Narration is simplified and clear.

@loganpenman4376 4 года назад

Legend thanks! I'm gonna start saying "Let's rip that" instead of "Run this bitch" from now on

@ligiaalves4182 4 года назад

Fantastic! Really well explained, thank you.

Unbelievable.. awesome..great..

@jessescopa5916 3 года назад

Thank you for this video! Any plans on creating a detailed video explaining the workflow of using groundwater tools?

@MapPractical 3 года назад

I'll look into it, but I cant put a date on it. Cheers!

very good tutorial!

amazing! many many thanks!

Well done tutorial!

@davidrudberg6076 3 года назад

You need to set the "distance" parameter in the "snap pour point"-tool to something above 0 for the tool to have any effect. Otherwise you are saying that you should look for a higher accumulation within 0 meters from the point, which will always give the same point as you have already made.

@MapPractical 3 года назад

True if you are not precise with the vector point that you make. I zoom way in and place it right on the accumulation pixel. The snap to pour point creates a raster with a pixel that matches the accumulation pixel exactly. This operation is done after the accumulation tool, so has no effect on it. It is for calculating the watersheds. Cheers.

@oscarsteve8181 10 месяцев назад

I keep getting a blank view on my map when I run the flow accumulation spatial analyst tool. Everything looks good until I run that tool.. I don’t get to see the water courses even when I zoom in. Help

thanks a lot, it was very useful for me :)

@jatinpandya4732 2 года назад

Thanks a lot! This was very helpful in understanding the entire hydrology workflow in ArcGIS Pro. Being not from hydrology background, what does the watershed polygons (or areas delineated as watershed) represent? What information does it convey?

@MapPractical 2 года назад

It represents where the rain water would flow over a given landscape. Cheers

Awesome 👏

@nilankahewa3039 3 года назад

this is next level of what I studied, good thing ,this session starts exactly where my studies ends, btw..this is like a whole semester of lessons, clearly explained in 20 mins, unbelievable

@MapPractical 3 года назад

Thanks, glad it helped! Cheers

@breaarvidson1026 3 года назад

Your video has been endlessly useful! Thank you! What's your resolution? I have a dem that's 0.7m res and I'm trying to figure out what's the best raster number to put in the raster calculator for the stream network. I want to make sure I'm capturing 1st order streams, but don't want to go so far as to include any areas of flow that aren't actually flowing. Right now, the layer I've created is using 30000 as the condition.

@heyzel302 3 года назад

Hi Ma'am, how do you quantify the condition that you should use based on the resolution of your DEM? I just wanna capture even the small flowing rivers...

@breaarvidson7593 3 года назад

@@heyzel302 Were you replying to me or the creator of the video? It seems like you're asking the same question as me! I have a general understanding of the major streams flowing into the lake that I'm working with so I'm able to justify the largest stream orders but not the smallest. I'm still having a hard time knowing where to stop to get just 1st and 2nd order streams because the resolution of my DEM is high enough to create flow paths where streams, even intermittent, don't actually exist. Its also includes urban areas so stormwater flow paths are also incorporated and cause trouble.

@xploregloballtd4575 4 года назад

This is really well explained and useful, thank you for posting.

@khalidsalim1079 3 года назад

My mind just can't understand the flow direction, I think it is the other way around!

@justinahern9729 Год назад

You're making me look like a rockstar at my job! Fantastic video and pace. I look forward to watching and learning more!

@MapPractical Год назад

Glad to hear it!

@sureshbhattarai4471 3 года назад

thoroughly enjoyed the learning..please keep sharing

@kellycoles5736 2 года назад

Thank you so much for sharing this. So helpful. You are a great guide through all this.

@mikebosko6880 2 года назад

This was a great instructional video - thank you!

@trailblazersonline Год назад

Since the clipped DEM does not include all the area for both watersheds, will the areas calculated be inaccurate?

@MapPractical Год назад

Yes, the tools will only calculate watersheds within the extent of the DEM.

@michaelghartcher863 3 года назад

Extremely helpful! Thank you.

@yoshuareece8785 2 года назад

awesome.

@goodgabi655 Год назад

First off, thank you for the very helpful video. When going through these steps with my DEM, my final stream network results in a lot of straight lines that do not follow the topography of the land. Could this be a result of the coarseness of my DEM, which I believe is at a 15m interval contour? Or should I experiment with some of the parameters in the GeoProcessing tools?

@MapPractical Год назад

The data link is below the description. It's a zipped gdb with one DEM in it. Cheers

@TheEsperanza91 Год назад

Thank you so much for this tutorial. Could you share again the data for this tutorial? I couldn't open the sources🙄

@reecesamuelson2274 Год назад

Awesome tutorial! I was struggling with attempting to do this on my own for so long. Done in 20 minutes....

@gisforforestry2336 3 года назад

thank you verry match its so usuful for us

@Don_n_2D 3 года назад

Great tutorial. I have a question. When I snap pour point, I had to move the point several times to get it to snap where it should have been. Is this normal, or where am I messing up? I zoomed way in to make sure I was on the correct pixel, but it kept placing it into an adjacent pixel. I have 8 points if that is relevant.

@alexandragodre9050 3 года назад

I also was wondering the same thing and have this same exact problem

@MapPractical 3 года назад

I haven't had that problem when I zoom way in and place the vector point. Try using the distance setting in the tool.

@robertwebb1125 2 года назад

I don't know if anything has changed since this video posted, but I am having issues with the last raster calculator, I have Con("FlowAccummulation", > 1000, 1) just like the video, but am getting a python syntax error. (ArcGIS Pro 2.9)

@MapPractical 2 года назад

It may be the version of Python. Try to build the statement from scratch with the prewritten statements.
