Create a polygon or some other feature that can model the new height of the water and set that at the base height(assuming the water level elevation is constant) and then you can see the areas that will flood. If you have a raster that indicates the water height, you can then use the Raster Calculator to add the depth change to each pixel and then set the base height to that and see the areas that are inundated. So depending on your data there are options.

The presence of the pyramids will affect how many overviews are created. If you remove the pyramids and then generate new overviews you are not really gaining much. I am not sure where you are going with this, but perhaps if you are looking to generate more overviews, you can use the define overviews to force more overviews to be created. This will give the image service more levels to choose from and increase performance. Perhaps you should take a look at this blog.

NetCDFs are primarily always WGS 1984. The ArcMap NetCDF tools work off the idea that the coordinates are always WGS 1984. There are a few exceptions in regards to the format and this document discusses some of them. The datum are always considered to be WGS 1984 even with the gridded attribute is included that is referred to here. Take a look at the information here and see if it helps.

Very open ended question. It is usually data specific. Usually if you ignore the pyramids, it will generate more overviews to cover for the data. The overviews increase the performance.

Also be sure to check the symbology of the raster in the mosaic dataset. If it is grey and you see the standard deviation stretch as None, then you will need the statistics. If it is grey and you have statistics, then apply a stretch. If the rasters are still grey then be sure that you have access to the data. By default, if the raster is not available a Constant Function will be appllied and the missing overview or raster will be grey.

The Delineate TIN should take care of the outside edge. The triangles you are seeing seem to be an issue with the data. Does your LAS Dataset have the same downward spikes? It seems that the issue is more with the data, the triangles that the delineate is to clear up the gaps along the edge, not remove from the inside. I would caution running the delineate not just on the outside.

Did you convert the contours to 3d in ArcMap prior to exporting them to CAD/Microstation? I would use the tool Feature to 3d by Attribute to convert the 2d contours to a 3d line. Then export to CAD/Microstation.

You also might consider the LAS Tools and specifically the txt2las tool. There is also the option to convert to an LAS with ArcMap using Data Interoperability.

File System rasters, would that be Esri GRIDs? If so can you indicate if the path has spaces or special characters in them? Or if you maintain the same location, but change the format of the rasters to a .tif or .img with the Copy Raster tool, will the process work. My assumption is that the tool fails due to the path of your data.

You have added a single band raster with a different spatial extent to another raster with a separate spatial extent and not gotten partial or incomplete output? You can add the bands with the same spatial extent like I described with the Combine bands tool. That is a normal workflow. Simply using a mosaic dataset to store data in a regionally similar area regardless of the number of bands is not necessarily a good idea. When I use Erdas Imagine to add a raster with one band to one with 3 bands, I am confronted with an error message and the process halts. I am not sure how you were able to successfully complete the task. [ATTACH=CONFIG]19450[/ATTACH] However, I would still recommend using the mosaic datasets, but be mindful of the number of bands for good output.

I would not consider adding a 1 band raster to a multiband mosaic 'basic' raster functionality and not being possible. If you try the same process with Imagine or Envi you will likewise get bad output. The mosaic dataset is built to handle varying spatial resolutions, but you set the bit depth and band combination when you create it. The rasters you add have to have those minimum requirements. If you created a 1 band mosaic and then added 3 band data, then it will succeed, but you will probably not like the results. You could use 4 band rasters in a 3 band mosaic dataset as well, but will lose access to the 4th band. The only workaround would be to create one mosaic with all your single band data and then one with your 3 band data in the same geodatabase if you desire, but not the same mosaic dataset. If you are trying to create a way to store the data then having the two mosaic datasets in a geodatabase will work.

There is documentation on how to create a group animation and one of the options is to turn the layers on and off. Per the help, you can create tracks that successively turn visibility on and off for each layer within the group.

I would consider upgrading your computer/video card. The unmanaged raster catalog maintains the links, so unless the network path is being altered after you create the mxd, which is highly unlikely. It appears that during the load of the mxd, your computer makes the decision of what to display each time due to available memory. Have you run the tool here to see if your system meets the minimum requirements?

It is not an Esri Tool. It was an ArcScript and the last published one looks like 9.3. I would recommend using the Interpolate Shape tool within 3d Analyst and then use the profile graph toolbar button. You can then export the values to a table that way.

If you add a single band raster to a multiband raster, then you will get bad results as you have seen. Perhaps you could use the Composite Bands tool and then repeat the 1st band two more times to generate a '3 band' raster, but I think you would have lost what you are looking for in that scenario. So based on your description, you have a single band classified raster and want to maintain that classification? Is that your desire? The mosaic dataset will not necessarily do that. The attribute table created will have information about the mosaic dataset, but not your custom attribute table. I would consider other alternatives to transfer the information, because you see your current result will not work. Perhaps you could use a map service and attempt to overlay the two.
