Isn't the Image Server Extension needed to serve out a mosaic dataset when some of your users do not have access to the file system location containing the mosaic and the imagery? Image Server Extension is pricey so we are still hosting imagery in SQL/SDE. Yes, we know it's not as fast and that we have to save a SQL backup of the data so it does takes basically double the disk space!

If most of the required vertices moves are rather small, you could use the Integrate tool or the topology validation process to snap vertices together. If you do either use copies (or make backups), or apply them in an edit session, since they change the input layer. You may have to play around with the tolerance setting to see what "snaps" most of the vertices together without unacceptably changing shapes. The same can be said for the Snap editing tool. If the foregoing can get a lot of the work done but you still have some manual cleanup there is an align to shape tool on the Advanced Editing toolbar. Another possible approach with gaps and overlaps larger than an acceptable tolerance would be to clean your layer, so that all overlaps and gaps become polygons, and then run an Eliminate selecting these polygons perhaps by size, but filled gaps could be selected by their lack of attributes), and then running the tool. There is no pure clean tool for shapefiles or geodatabase feature classes as there is for coverages, but if you have ArcGIS Advanced you could convert to lines and points and then build polygons from lines and points, or convert to a coverage. ETGeowizards has a polygon clean tool with the option to create points wherever there are overlaps, but I think it is one of the paid tools.

Thanks jbswain that's working alot better now. I have an aerial imagery draped over a DEM. I was wondering the best way to rotate around the image at a fixed point. It gets a bit choppy when I try to do it manually.

Bump to see if anyone else has had success with developing a workflow to do this?

Hi Mark, Here is an example on how to do this using the arcpy.da.UpdateCursor (10.1 or beyond is required): import arcpy from arcpy import env env.workspace = r"C:\temp\python\test.gdb" fc = "featureClass" with arcpy.da.UpdateCursor(fc, ["field1", "field2"]) as cursor: for row in cursor: if row[0] == 1: row[1] = 'Woodland' if row[0] == 2: row[1] = 'Arable' ...... ..... cursor.updateRow(row) del cursor, row Thankyou very much that worked a treat 🙂

I've been playing around with the 'Extrude Between' tool in the 3D analyst extension creating 3D models of layers of geology. I want to create a layer between the last geological layer and a DEM off the surface. Because I have to use TINs for the 'Extrude Between' tool I'm losing some of the detail from the DEM. I was wondering if there is a way to create a 3D model using raster images? So my idea would be to interpolate the geology depth to create a raster surface of depth and then extrude between this and the DEM surface.

Great thanks for your help in this 🙂

Thanks Hornbydd. I've just been looking at applying a Maximum focal filter over say a 50m area and then subtracting this from the DEM. These seems to give an indication of the depth of material removed from the landscape. I'll definitely give your suggestion a go and see what I can come up with.

I have a high resolution DEM and a series of point depths collecting during a survey. The points represent depths of soil as certain points. I can model the soil depths using kriging to produce a soil depth surface. What I was wondering about is what would be the best way to represent the difference between soil depth and the surface elevation of the dem? Also I was wondering if there is some kind of way that I could create a 3d representation of the soil layer? Thanks for any help!

...or can they use float? The problem is I have some elevations I want to compare but for exampe the elevation is 423.617m

Show the difference between elevation and soil depth layers?

Can TINs only use integer values....?
