Can you elaborate on the file being 'too long'?  ArcGIS Pro should be able to handle a large volume of features.  What's the data source? If you have a 'County' attribute or another attribute which distinguishes the polygons/features from each County, you could use a Definition Query to limit the results.

I think it should be deleted but it's been a while.  It may be due to delete protection being on the Hosted Feature Layer. it shouldn't be a weird duplicate in any case, rather just another hosted feature layer with the same name.  The XLS should point to the new service.  You'll see different endpoints in the REST interface e.g. service_784373byg478erjgjrg439 You should see the new endpoint referenced in the .iteminfo and debug\createService.json files in MySurveyDesigns folder for your Survey. ...

Can you open the developer console in AGOL or Survey123 site and check for network messages when adding an attachment via the web apps or data tab?  I'd check the settings of the hosted feature layer and see for any differences between the envs. ... View more

Do you have a Network Dataset built or can you obtain one for your area?   otherwise: Cost attributes—ArcGIS Pro | Documentation an example cost for car_drive_time could be: time (hours) = length (km) / speed (km/h) for a segment/edge 60km long and a speed limit of 120kph: time = 60/120 = 0.5 hours for truck_drive_time, the speed limit might be 60kph, so time = 1hr     ...

It's likely going to be part of the Route Layer in the Layer List which you can expand and turn off by clicking the eye symbol, or it's a Sketch Layer you can again turn off by clicking the eye symbol. ... View more

What's your input arguments to the tool and what format is the DSM in? Possibly projection?  Something like trying to calculate for 25 decimal degrees if the raster is in WGS84. Or try Geodesic Viewshed. I'd be tempted to export a subset 30km square as a tiff and use that as a test to rule out anything. ... View more

Nothing immediately obvious to me, If there's an operation to clear out data from the GDB then I can't see it. I think you need to share your full code and also not a screenshot, it's not very helpful. Code formatting ... the Community Version - Esri Community ... View more

how I understand it is that the the Geodesic buffer in NAD1983 Geographic is not a regular annulus or circle.  The circle or annulus will be like a squash ball squished against the poles.  This greater area of the buffer above the buffer origin point (for Northern Hemisphere) then forces the Centroid up to account for the changed centre-of-mass.  This will increase non linearly as you increase the buffer distance.     I'd use a big (1000km) geodesic buffer and then visualise it in the same geographic projection.  I think when you see that it would make sense what's occurring. For the UTMZ13 coordinate system I may be wrong in this one as this topic is admittedly very confusing - but it seems to me that it's showing the distance distortion away from the central meridian of the transverse mercator projection (105 West?).   I would then say your buffer point is West of -105 degrees, and if you recreated the example with a point East of -105 degrees you would see the centroid shift in the opposite direction.  ...

I've done the same using a 'normal' coordinate system and all the Centroids are the same as I'd expect.  Calculate Geometry Attributes and Spatial Join 'Have their Centre in' work as expected. I think this may be Aerial distortions from using WMAS coordinate system.  I would guess that if you did the same experiment in the Southern Hemisphere that you would see the opposite drift of Centroids. Or it's some difference in versions causing the default to be 'inside' which seems a bit unwanted to me. ... View more

I don't understand how or why the Centroids would be different for a donut annulus, even for multipart polygons. ... View more

I think the issue that you're seeing is that if the demand weight is higher than a capacity point can take, then that capacity point is simply skipped. There may be some way, but it might be best to generate points for each student.  Perhaps: Buffer the excess school points a small distance 'Create Random Points' tool -> constraining feature = the buffer, number of points = excess student field Spatial join 'intersect' the points to the original buffer to transfer school attribute (maybe used in 'Group' field later?) Run the analysis.  ... View more
