David, I had your incident escalated, and I just checked with the analyst and we are awaiting your data. Jorn, Can you contact Support?  Or can you post a TIN here? Jakub, Have you had a chance to upgrade and work with your TIN's? All, We are very interested in getting to the bottom of the issue you are experiencing.  Best, Eric ... View more

Ken, Is the data you have available for download? Could you point me in the right direction so I can download the same as you? SDTS dem data from USGS should just work in ArcGIS per the link I previously provided. If the data was just in-house data and not recently downloaded we can work together to get the data here via our ftp site. I'm more concerned about it not working in its native form. The only oversight would be if all SDTS raster data is not readable in ArcGIS. When the 8.x toolbar, which was VBA, was removed along with pretty much anything VBA in ArcGIS, we added native support for this format. At ArcGIS 10.1, customizations built using VBA are no longer supported. We began this transition in 10.0. I downloaded sdts dem rasters from GeoCommunity this morning and after unzipping the file, I could add the .ddf file right into ArcMap and begin other processes such as hillshade, slope, and contour. Attached is the native sdts dem raster displaying in ArcMap 10.1. It should be the same for 10.0, and you should not have to run any conversion tool.  Perhaps you could contact Esri Support so they can troubleshoot - they have better tools for interacting with you than I do here on the forums.

Greetings, You can go the the View menu > View Settings and check the box for 'Directional Arrow'. The arrow shows you the x, y, and z axis in the scene and has an indicator for North. See screenshot. This is in 10.1. As for scale, it varies when in a perspective view like ArcScene. A scale bar would only represent one location in the scene, hence no scale bars. ... View more

Hi Ken, Have you tried just adding the data to ArcMap?  SDTS (DEM) is listed as a supported format in terms of reading ability.  If you need it in another format you can just run Copy Raster tool. Best Regards, Eric ... View more

Hi Eric, I don't have the right answer for you, but I have some things for you to think about. 1. It's common for horizontal accuracy of pixels to be measured by pixel size/2, which would put your orthophoto at a 3" horizontal accuracy. This would be amazingly accurate. This measure of accuracy is more typical of satellite imagery though. 2. Your orthophoto as the name implies, was orthorectified using a DEM. The resolution of that DEM is critical to know. A 30m v 10m v 1m DEM could easily account for the pixel not being where your GPS point data indicates it should be. 3. What was the accuracy of the source data the image was georeferenced to? 4. Did you really 'georeference' the image in ArcGIS? What was the RMSE? What was the transformation used? How many control points? Or did a vendor supply an image that included georeferencing information? 5. Do you have other datasets to add to the mix to compare? These should have known accuracies. 6. Is your point shift uniform - like all to one direction? If yes, I would suspect the points in this case, but if not then I would suspect the image is slightly wrong. 7. Does the provider of the orthoimage provide metadata regarding its accuracy? (if applicable) I'm inclined to think your points are more correct. Perhaps you could re-georeference the image using highly accurate gps points once they are all collected. Just a thought. Best Regards, Eric ... View more

Hi Jose, You can run Create ArcSDE Connection File tool. Best, Eric ... View more

Jakub, The product wouldn't make it out the door if ArcScene crashed on ALL systems simply by adding a 3d feature class to the application. As for the TIN issue, I have no problems rendering TIN's of all sizes in ArcScene. Mike and Darroch should probably contact Esri Support so they can troubleshoot their systems. Below is a screenshot of the new LAS Dataset in ArcScene. It has ~ 144 million points inside. The default setting is to have a max point in display of 12.8 million. It renders fine and I can navigate seamlessly even after switching the default rendering (points) to be a surface using elevation - which is how a TIN would display. Please upgrade (at your convenience) and repost your results to this thread. If I were seeing the same as others on this thread I would not suggest that, but I am comfortable going out on a limb here and saying the issues described thus far are isolated issues and not a trend in the software.

In ArcGIS 10.1 the Topo to Raster tool was enhanced and you can now use the 'Cliff' option when setting the type of layer for input.  It should work like a 'barrier' or 'fault'. Kieran, If you have contour data you can use Topo to Raster, or if it is very large (since Topo has some limits) you could build a TIN/Terrain dataset, then convert to raster using one of the conversion tools. What problems are you encountering, if any? Best, Eric ... View more

Craig, You can't technically do it directly with the multipatch, but you can run the MultiPatch Footprint tool, then the Create Random Points tool using the footprints as the constraining feature class. The 3rd usage point in Create Random Points documentation indicates how to assign random values to randomly placed points, if you needed random Z's so you could later convert the points to 3d points. Best, Eric ... View more

Hi Craig, Have a look at the Inside 3D tool.  This will give you a table telling you which points are inside the multipatch.  Join it back to points and make selections accordingly. Best, Eric ... View more

The points are converted to raster internally. You probably have a resolution large enough that two or more points are in a single cell. Since the cell can only be 1 value it takes the point with the highest feature ID. This is discussed in the tools documentation under "Usage". You should note that since you are using points, not polygons, your really just sampling the input value raster. It's not actually calculating a mean value.  You should see that Min, Max, and Mean are all the same value.  If you were to buffer the points and use those polygons as the zone features, then you would get a real mean calculation.

Where is the source data? Is the catalog managed or unmanaged? You indicated this was someone elses project...Do you know if they loaded the catalog with UNC paths or with some mapped drive letter to a network location? Perhaps the data was local to their machine? Typically if you are going to have multiple people accessing a catalog you would load with UNC paths so that anyone who connects would just see the data. If they loaded it from a network location, like Z:\\data\ then you to would have to map that network location with the same drive letter. If you are mapped there but you have Y:\\data\ then the catalog won't find the data. What happens if you build a small raster catalog of your own since you have access to the data? You can run Export Raster Catalog Paths tool with the 'Broken' option to see if the paths are indeed broken. Eric ... View more

Greetings, Is it a raster catalog you're working with?  What happens if you zoom in to just 1 or 2 footprints?  By default, if more than nine images are in the current display extent, raster catalogs are displayed as a wireframe; otherwise, the actual raster data will be displayed. Using the wireframe speeds up the display of raster catalogs. The default of nine images can be changed in the display properties of your raster catalog or on the Raster tab on the Options dialog box. -Eric ... View more

Hi Julian, What exactly do you mean they are in the same coordinate system and geoid?  Any Bing service should be using WGS_1984_Web_Mercator_Auxiliary_Sphere on GCS_WGS_1984 datum.  Are you saying that you projected your OS data to that coordinate system?  What was it originally if you did project.  The OS data I'm familiar with uses OSGB36 datum which can vary from WGS84 by as much as 120m.  The shift you describe could be because the appropriate geographic transformation was not set at the time you projected the data, if you did...
