Not sure what NHN is, I think raising the water above ground level would take some of the Hydrology toolsets to model, but I'm not smart enough to advise on those. Also I'm sorry, I really don't understand the question either, maybe its a translation issue. Good luck.

Are you saying you want to calculate the amount of 45cm cell values in your DEM? The method would be similar to this one: Re: How to calculate percentage of land covered by... - GeoNet, The Esri Community If you need the area, multiply the count by the pixel size.

You should be able to create a Raster Attribute Table (Save the raster into an FGDB first I think). Raster dataset attribute tables—Help | ArcGIS for Desktop Then you'll have a table of each raster value and the corresponding sum of cell counts. It would then be fairly easy to sort this out in excel, or you could reclassify the raster first before building the attribute table.

You could generate a near table, get rid of any values over 1300 and then use the XY to line tool to generate the edges you need. What's your end-goal with this?

You should be able to point directly to it by adding content in Portal via a url (Content -> Add Item -> From the Web , in this case something like MyDomain.server/rest/services/MyStuff/MapServer/0) which then becomes a feature layer.

It's a bit dated, but the technique should still be the same Connect point to closest feature in ArcGIS 10.2 - Geographic Information Systems Stack Exchange generate a near table and then create the lines from that. (I guess you delete any table values over 1300 before you generate the lines) As to the other questions, it might be better to state what you want to achieve rather than us helping you with a solution you've proposed.

I've tried it and seems fine. Could you provide a screenshot(s) and what version of Pro you're using? You've also downloaded the data from here right? Python Scripting for ArcGIS Pro (Esri Press)

Did you colour balance before building the footprints? Have you got a stretched symbology renderer applied on the RGB? Maybe set it to None. Maybe check the skip factor on the statistics as well. The only thing I could say is to mess about with some of the balancing / dodging options. 😞

With the value as 0, its calculating a huge slope in those areas, which is logical. I'd definitely call those lines of 0 value missing data.

Looks like a logical result of the mismatched tiles, what are you expecting or wanting to see instead? I guess you could interpolate the missing DEM values.

Sure, when you find the longest segment of a line within the polygon, it would have coincident geometry with the original line to match it back.

You can add the attributes of all intersecting lines to your polygon in the field mapping options of the spatial join. psb excellent article on it. Spatial Join’s hidden trick or how to transfer attribute values in a One to Many relationship | Esri Australia Technical Blog (wordpress.com) you could of course script it, but I'd just to the spatial join, appending all the SHAPE_LENGTH s to a delimited field which would look like - 123.45, 45.56, 789.9... you could then create a new field then do a field calculation, something selecting the largest value from yourfield.split(",") edit - just read that you want the longest line WITHIN the polygon, I'd guess you'd have to clip all the lines to all the polygons, then split the lines again by the boundaries of the polygons (run a polygon to line I think for the split) and then do the join.

you just need to change the output name of Slope_1 to Slope_%n% %n% gets replaced by the number string of each iteration, Slope_1, Slope_2 etc. The link blow should cover all aspects of this: Examples of in-line variable substitution with ModelBuilder system variables—Help | ArcGIS for Desktop
