I did find a work around. I loaded the WMS into ArcMap (which has always rendered this service just fine). I created a layer file for the service and then added the service using this layer file. The WMS worked fine this way. But if I tried to add it directly as a WMS service in ArcGIS Pro, it won't render at all. ... View more

I had something similar occur. I'm not sure what's going on. I tried one imagery service and it didn't work. This service had multiple layers. However, I added an imagery service using a layer file that only had one layer in it and that drew fine. One other difference was the format of the service. The one that worked used a REST endpoint. The one that didn't used some other kind of configuration. This is the one that didn't work - http://geoint.lmic.state.mn.us/cgi-bin/wms? ... View more

For anyone who reads this, I ultimately just dumped StereoAnalyst and switched to Summit Evolution Lite from DAT/EM. It has been working much better for me. I'm about to import projects covering 10,000 square miles and thousands of stereo images and still remains quite responsive. ... View more

When you use the georeferencing tool you should end up applying a transformation model to the image. When this happens, the pixels of the image are realigned to according to the model and to do this the pixel values will have to be resampled (e.g. nearest neighbor, bi-linear interp, or cubic convolution). I suspect that the precise orientation and alignment of the pixels will also be affected by your environment setting. Try setting your output coordinates. You could create an extent rectangle for your entire project area and then converting it to a simple grid and using that grid as your Snap Raster in the Output Coordinate section of your Environment Settings. ...

I think this is best handled in the interpolation process rather than on the back end of the interpolation process. My suggestion would be to use 3D Analyst to create a terrain dataset from your bare earth LiDAR points. Create the terrain (3D Analyst>Terrain Management>Create Terrain) Add your LiDAR points (3D Analyst>Terrain Management>Add Feature Class to Terrain) If you don't have edge of water breaklines, you will want to delineate them yourself and add them to the terrain model. Add breaklines. (3D Analyst>Terrain Management>Add Feature Class to Terrain) Then build the terrain dataset. (3D Analyst>Terrain Management>Build Terrain) After this step you should be able to view the terrain data on-screen and see if it is interpolating correctly over water features. If it doesn't look right, you may have to change the surface feature type for your breaklines. Here's the link to the help page. http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//005v0000000z000000.htm Once you have everything looking right in the terrain dataset you can simply convert it to a DEM (3D Analyst> Conversion> From Terrain> Terrain to Raster) OTHERWISE: If  you don't have 3D Analyst, you could digitize a region for your water body, convert it to a grid with a constant elevation, and then use the Con tool in Spatial Analyst to replace the values of the original DEM with the new values from your newly created water elevation grid. Digitize water polygon and specify the desired elevation in an attribute field. Convert to raster using the elevation field as the raster value. (Conversion Tools>To Raster>Polygon to Raster) Use the Con tool to replace the original values with the new water body elevation values. (Spatial Analyst Tools>Conditional>Con) ... View more

Fernando; Lady Jane is right that you can use the ArcHydro tools to burn your culvert data layer into the DEM, assuming you have a data layer for the culverts in your study area. You can download ArcHydro for ArcGIS10 at this ftp site. ftp://RiverHydraulics:river.1114@ftp...Hydro/Setup10/ The function to burn in your culverts is found under Terrain Preprocessing>DEM Manipulation>DEM Reconditioning. You can also achieve a similar effect with out-of-the-box tools in ArcGIS. 1) Assign each culvert a unique ID. 2) Use Zonal Statistics (Spatial Analyst Tools>Zonal>Zonal Statistics) with the culverts being the zone layer and the DEM being the raster layer. Select the statistic type to be the minimum. This will give you a new grid with the minimum elevation under each culvert and NULL for grid cells where there is not a culvert. 3) Use the Raster Calculator (Spatial Analyst>Map Algebra>Raster Calculator) and enter in the following code. Con(IsNull("burn_elev") == 1,"dem","burn_elev") Where "dem" is the name of your original DEM and "burn_elev" is the output from the zonal statistics tool (minimum elev beneath each culvert. This code will tests the output from zonal stats and if it is NULL (no culvert) it will substitute in the original DEM elevation, if not it will use the minimum elevation under each culvert. This method also assumes you have a data layer for your culverts. If you don't have a data layer for your culverts it gets considerably more complicated and time consuming. Here's a link to a potential semi-automated method if you don't have culverts. http://pubs.usgs.gov/sir/2010/5059/ ... View more

Here's one possible concept for a process. You can select specific colors from an image and create a new raster dataset with the selected colors. You can even do this sort of color filtering/selection with software like Adobe Photoshop. You can then use a raster to vector conversion tool. This would probably work better if the image were originally stored as an 8-bit, unsigned integer raster. JPEG often uses dithering and thus the edges of your symbols are likely to be some gradation of color from the pure symbol to the background color. Adding few more details to this concept. 1) Convert the image to a single band format, with 16-bit data or less (probably better if you can use 8-bit). I don't know the specific tool to use in ArcGIS, but this type of image processing is readily available in lots of basic image software like Adobe Photoshop. 2) Bring the image into ArcMap and use the georeferencing tool to georeference the image (if it isn't already georeferenced). 3) Add a color map (Data Management>Raster>Raster Properties>Add Colormap) 4) Use the reclassify tool (Spatial Analyst>Reclass>Reclassify) to reclassify the specific color that corresponds to one of your desired features to a value of 1 and all other colors reclassified to a value of zero. 5) Use the tool Raster to Point (Conversion Tools>From Raster>Raster to Point).

My first thought (a semi-educated guess) is that it could be a problem with your pyramid files. If you go to ArcCatalog, you can right click on each of the raster datasets and select "properties". Scroll down the properties to the section called "Raster Information". There should be an entry in this section called "Pyramids". You can see if pyramids have been created for each dataset, what the parameters are for the pyramids (e.g. how many levels and resampling method). If the pyramids property is different between your DEM, aspect, and slope, that might provide a clue regarding this problem. If you don't have pyramids for the slope dataset, calculate one. If you do, you may want to rebuild the pyramids. ... View more
