Hi Kory Thanks for the feedback. Good to know issues can be replicated.  Best wishes Mervyn ... View more

Thanks Dan. Just tried that but it did not make a difference.  ... View more

Dear Kory and Jonathan Thanks for checking and responding, much appreciated, but I can still confirm that I have done some more testing and I have a very inconsistent experience. I have been testing a bunch of shapefiles of different projections and I seldom get it to work as expected. I have on occasion managed to get it to snap to two polygons of the same layer that occur on the edge (but more often not).  It also frequently snaps to an unknown intersections.  Please do take a look at this shapefile Dropbox - snapping.zip  I have annotated the below image with where I have had success snapping to intersections and where not. I have tested this on two computers so the results should be reproducible. This is also a multipart polygon. Exploding then resulted in fewer snaps than reported below.  I would appreciate it if you could still look into this. ... View more

Sorry to reopen this again but after a bit more testing I see that Intersection snapping does work but just not the same as it did in ArcMap, it is not as inclusive or consistent and I would like to make a plea for the Pro snapping intersection tool to be revisited.  I would like to illustrate. As stated above, I wanted to snap to the intersection of two farm polygons that occur on the edge of the farm layer. In ArcMap, intersection snapping does snap to where these two polygons meet on the edge.  However in Pro the snapping tool does not identify this as an intersection point. In Pro intersection snapping seems to work best where two different snappable layers intersect, not polygons within the same layer. It can work but then it is strangely inconsistent and inaccurate from what I can tell. That is at least my experience.  From the tool help, it does say "Snap to the intersection of two or more line or polygons features when using interactive map tools" ... so it really should snap to polygons within the same layer.  ...

Correction, after rebooting I did get Intersection snapping to work. I apologize for wasting your time.  ... View more

From my somewhat limited understanding of this .... and I welcome to be corrected here If you have defined a vertical coordinate system, then you may get up to 3 spatial references listed here. The top one is the projection of your data. The second one describes the modelled shape of the earth - your datum/ellipsoid/spheroid (also referred to as  geographic coordinate system by Esri). And if you have a third one, it would be the vertical coordinate system.  From your screengrab, you will notice that the two spatial references are different as only the second one refers to the datum and spheroid. If your data is not projected, and it is in geographic coordinates, then only one spatial reference will be provided to you (the second geographic coordinate system in your screengrab with spheroid and ellipsoid).   Do see Coordinate systems, projections, and transformations—Properties of maps | ArcGIS Desktop  ...

Hi Scott Thanks for writing. I respond below to your questions. 1.  Destination 2. Yes, the layer files references the landuse FC but the layer file is not directly part of the relationship. In ArcMap, I think all the landuse referenced layer files would have opened, not just the one in the relate.  3.  One to many 4. I open the table to which I have added the relate, I then select a record, then I go to Data>Related Data, select my relate, and the related records are not shown. As soon as I remove the lyrx file, and I repeat this process, then the relate shows me the correct attributes from the landuse layer. 5. No 6. I can go one better and provide the data set to you. Dropbox - RelateBug.rar  Firstly, load the Landuse layer and Landuse_Statistics table from the geodatabase. Open up the Landuse_Statistics table and create a relate to Landuse using the Land_use field in both. Select any field from Landuse_statistics and confirm that relate works. Then add the Excluded Lands.lyrx (set the data source to Landuse) file and repeat this process, the relate wont work.  Thanks for looking into this. Mervyn ... View more

What is the source of your GCPs? Offhand I cant think of any reasons why your drone images are placed at different heights. Did you perhaps try adjusting the image properties? Image Properties > Image Options >  Adjust Image Altitudes.  It would be useful to know whether the altitude values for each image also show this abrupt change in altitude? This would be easy to see from the image properties pane as in below image. Therefore pointing to whether the problem lies with the recorded altitude metadata values or the Drone2Map/GCP processes.  What makes you think that the two elevation surfaces are not showing up? They are invisible as they are only used to adjust the height of the 2D layer pixels but you can see them if you turn on Shade Relative To Light Position on the Elevation Surface Appearance tab. Or you could try draping over any other raster surface.  Your situation is certainly unusual and I don't think I have any answers but it will be useful to better understand what is going on.  ...

Hi Diana Do you know what software created the shapefile?  I can view the geoprocessing history of some of my shapefiles but not all of my shapefiles contain that history. It may be more limited than geodatabase feature classes. Regards Mervyn ... View more

Hi Diana There is metadata and metadata. Every feature class has its own metadata which ArcGIS keeps track of.  In what format is your data? A feature class, shapefile, AGOL feature layer? Metadata more limited for shapefiles.  If your data in a feature class, and you change your metadata type under Options to anything else other than the default Item Description, you should see a section called Geoprocessing history which keeps track of all the geoprocessing tools run on your feature class.  Below is an example of the geoprocessing history that Pro keeps track of.  ...

If you are only interested in converting a raster to a format that can be downloaded onto Collector then try creating a tile package (TPK) and side-loading that onto the device. Rasters are not support in vector tile packages. For more detail, do see Go offline—Collector for ArcGIS (Classic) | ArcGIS  and https://community.esri.com/thread/90177  If I am not editing data, then I usually create a TPK of the raster data, then include that in a MMPK with my vector data (with pop-ups and bookmarks) that is easily side-loaded onto Explorer for ArcGIS.  ...
