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

Following on from this thread Re: Creating multiple non-overlapping buffers - Esri Community I've noticed that Centroid calculations for GCS features seem to be calculate as if the lat/lon coords were transcribed onto a cartesian plane i.e. Plate Carree and the Centroid calculated from that. It all seems a bit off to me. Am I missing something obvious?

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.

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.

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

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.

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

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.

Just to be clear - you want to transfer the attributes of the census polygons to the points? What do you mean by 'the polygons do not show on the map'? Do you mean they don't show on the map when you display the original census data on the map? otherwise - if you mean where are the polygons in the output feature class then the target is points and only the attributes (not geometry - as it's either a point or a polygon, not both) of the join layer (census polygons) are transferred to the target point layer. i.e. I'm assuming you just want the census area attribute transferred to the points so I don't understand the 'polygons' not displaying part. If they don't display from the outset - then that's the issue. You could run a Check Geometry and Repair Geometry on both features, but I'd first reference your data in the Geoprocessing tool by selecting it from the file browser option or dragging from the Catalog pane. This stops any layer issues such as definition queries/filters etc. I'd also look at your filenames and ensure they have no strange characters or spaces, and are stored as Geodatabase Feature Classes. Also change the output file location to a local drive rather than OneDrive etc. and again make it a Feature Class inside a Geodatabase. I'd also be tempted to just use the 'Intersect' spatial relationship option rather than 'Within'

I think you'd use option such as .STIntersects(), .STContains(), .STWithin() Whichever operations are available within your database engine (may not be ST geom type etc.) We're talking outside of Esri here so go to your DB documentation. A query layer in ArcPro might achieve the same thing also (with extra steps).
