What you're seeing in the popup is default rounding,  I don't think it's truncated your data values.  The easiest way to see this would be to start editing the data and you'll see the true precision of the values. in the general U.S latitude, 8 decimal places would be (roughly) 0.1cm on the ground, 6 decimal places would be 10cm. Are you sure that the coordinates are maybe not a bit funky?  Maybe a check on google maps for 2 values. ... View more

Possibly might accept some html like <br> but unlikely.   I'd enter it manually then read the description value returned from the Python API if you haven't tried that already. ... View more

Possibly these, but never used them. if you don't have smaller zones to use as initial input I might create a Fishnet and then use that to divide up the zones further using the Split tool. https://pro.arcgis.com/en/pro-app/latest/tool-reference/spatial-statistics/buildbalancedzones.htm https://pro.arcgis.com/en/pro-app/latest/tool-reference/spatial-statistics/spatially-constrained-multivariate-clustering.htm ...

i think the simplest way is to create a new polygon using the draw tools which covers your extent/area.  Use this polygons as input features, and the original polygons FC as the erase features in the Erase geoprocessing tool. https://pro.arcgis.com/en/pro-app/latest/tool-reference/analysis/erase.htm ...

I'm guessing the manage bookmarks option isn't working. First I'd save a new copy of your APRX for this: If you open the APRX using winzip or 7zip etc you have a folder called 'map'.  Inside there, the 'map.xml' seems to store the bookmark config. I'd edit/delete what you need from there (When doing this, I would compare the map.xml from another working project with bookmarks to avoid any formatting mistakes or deletions). I've not tried this and it's likely not recommended, and also again - do it on a completely isolated copy of your original, and backup the map.xml just-in-case anyway. ... View more

It doesn't matter.  The network drive-time areas/isochrones are only computed from paths along those routes regardless of restriction polygons outside of a viable route.  You could clip the polygons by the roads/paths (with a small buffer distance), but it would very much be unnecessary for the analysis. ...

I would run your slope analysis and break it into class breaks which define your estimated walking speed. 0-10% = 20% slower  20-50% = 40% slower etc. raster to polygon and set polygon values as 1.2, 1.4 .. (1.2 is 20% slower, 0.5 would be x2 faster - see doc below 'scaled polygon barrier')   https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/barriers.htm#:~:text=A%20restriction%20polygon%20barrier%20prohibits,shortest%20path%20between%20two%20points. set the scaled polygon restriction and that should be it.   however this does not account for the downhill 'speed-up' you want to incorporate.  this is much trickier imho and really needs you to populate the network edges (paths) with to and from values in each possible direction.  You'd also need to first find the direction of the slope with the Aspect tool.  If your analysis can suffer not including downhill/uphill comparisons - I would definitely not go down that rabbit hole.  it may even be easier to produce some cost surface with a masked restriction to only include paths - again a technical rabbit hole. ...

From your pictures it looks like the lowest distance (miles) route is taking a road which isn't on the map at that scale and probably a back-road/lower speed limit.  Have you looked at the speed limits of the road sections to compare? The fastest 'time' route looks to be going into a population centre.  I'd reckon ArcGIS probably isn't factoring traffic factors and is just going off the maximum speed limit if Google Maps is suggesting differently. ...

Good idea.  I can see a few use-cases for this.  Did you run the second picture as batches and clip? ... View more

It's been a while but I think the Webmap doesn't contain feature layers where you can update line that.  It's a big block of JSON - could be wrong however .  I'd try something like: for layer in web_map.definition["operationalLayers"]: if layer["title"] in ["first layer", "second layer"]: if "layerDefinition" in layer: layer["layerDefinition"]["definitionExpression"] = "<insert definition query>" webmap_item.update({"text": json.dumps(web_map.definition)})     ...

What's the process, is it automated?  - something like select by location iterating through the footprints as the selecting polygon?   Select by Location https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/select-layer-by-location.htm Already has a 'Relationship' property - 'Have their center in' which may solve the issue (depending on what your process is).       ...

Also would check for any crash dump files in %LOCALAPPDATA%\ESRI\ErrorReports and Windows event viewer. ... View more

It's most likely not the case of saving into a Project, rather that saving as s shapefile .shp has an error, where saving as a Feature Class inside a File Geodatabase .gdb does not. There are several structural differences to .shp and .gdb Feature Classes such as field name lengths, .shp does not contain topologies, global IDs, only basic field types supported, a 2Gb file size limit, domains, subtypes not supported etc. If I were to guess, you may either have a file over 2Gb, or a Date field (.shp does not store datetime in a  single field - only Date)     ...

It's just wrong really.  The scale text and bar must be linked to the other Map Frame, or the bar and text are static or graphic elements.  I would go into google maps (other map services are available..) and do a quick sanity measurement to see what might be going on. It's very basic, but scale bar for each map is to the left of the centre marker, and 8000ft (2 x scale bars) is to the right.  Green line is difference.   ... View more

It's not completely obvious but it's there.     var words = Split($feature["YourFieldNameHere"], " ") return Concatenate(words, TextFormatting.NewLine) Starter for ten, insert your field name and adjust to suit.  ... View more
