The math involved with calculating Slope usually results in floating point rasters. i.e. 32 bit float.  The conversion tools only accept Integer values.  You can run the Int tool to truncate the values or you could reclasssify your slope map into integer values, then do the conversion to polygon.

Brett, Those links are pretty much all related to ArcGIS 10.0.  For CIB in 9.3.1 you should make an MA (military analyst) Catalog that resides in a File Geodatabase.  ArcSDE MA Catalogs will take some time to build because you're actually loading everything in the database vs referencing it from its location on disk (known as unmanaged). Depending on the amount your loading it may work or may not.  Esri recommends File Geodatabase, unless you actually have a CGA, which comes with custom data loading tools to get around some of the issues with loading massive MA catalogs into SDE in 9.3.1.  Here are some links to get you started. An overview of data management Military Analyst RPF catalogs Please make sure you're loading the data to the FGDB MA catalog using UNC paths rather than a mapped drive letter. For the level of detail comment -  This often refers to creating cache at different scales. e.g. creating a cached map service.  For CIB and MA catalogs though, I would interpret this to mean what product within the MA catalog is most appropriate to display given the current map scale (level of detail) - This the software just handles for you but only if its in a MA catalog.

A Tiff file is a raster dataset.  Perhaps you want to look in the 'Convert from Raster' area.  It sounds like you want to run Raster to Polygon.  What kind of data is represented in the Tiff? Regards, Eric ... View more

Hi Brett, Did you make a raster catalog or a mosaic dataset to store the CIB?  In either case, you probably just need to zoom in to see the data.  This is a really good starting point for working with CIB in version 10.0. Imagery Basemap Template "The Imagery template and the walk-through exercise in the accompanying "Using the Imagery template" document are designed to teach you how to add military imagery data in CIB format to mosaic datasets using ESRI recommended practices. Mosaic datasets are new at version 10 of ArcGIS and are the recommended data type for storing CIB data in ArcGIS." Getting Started with the Imagery Template PDF For working with DTED I recommend this 3 part series.

Hi Esther, There are a few things that stand out.  First, the gray image with weird Min/Max values - that is an indication that your dataset does not have statistics.  Please run the Calculate Statistics tool on that dataset, especially if that is the original.  The second image that has the right values, but looks crummy... What were the settings when you exported? Lastly, the image you display from GlobalMapper is not a DEM - it's a color shaded relief (fancy hillshade), so the image you display at the bottom should look strange if you applied a hillshade function to a dataset that is already a hillshade. Do you have the original DEM's?  If not, all you should have to calculate stats. Regards, Eric ... View more

Ben Ok, so some of your data is using a geographic coordinate system.  This is the problem.  LxWxH can't have mixed units of decimal degrees and meters.  The precise method you inquire about is to project those rasters that have units of DD to a projected coordinate system that uses Meters.  To do this, open the Project Raster geoprocessing tool. Since this is elevation data, please make sure that when projecting the data you change the resampling method to Bilinear.  If you happen to switch datums be sure to set an appropriate geographic transformation for your area.  Once X,Y,Z (I'm assuming Z is already meters) are the same the volumes should make a lot more sense. -Eric ...

Hi Ben, The delimiter doesn't sound like the issue for now.  What is the coordinate system of the data?  To check, open the layer properties and go to the source tab.  Is it using meters for the unit?  We need to verify that your X,Y,Z units are all meters. How large are these datasets?  Are they publicly available for me to download somewhere? -Eric ... View more

Hi Ben, If your projected coordinate system is in units of meters and the pixel values are in units of meters, then the volumes will be calculated in cubic meters.  What coordinate system are both inputs using and what are the z units?  You are using the DEMs of the glacier surface as the "After Surface", correct?  Essentially you have no cuts -only fill.  If ultimately you want to visualize these volumes in the form of a multipatch feature class or perform analysis on these volumes (shapes), I would suggest having a look at the Extrude Between tool followed by the Add Z Information tool.  It only works on TIN's though, so you'd have to convert your raster data to TIN.  If they are very large, it may not work because we have to dump everything into memory for that particular tool and you can run out resulting in tool failure.  If it were too large (too many nodes) you can thin the TIN during the conversion or post conversion with Decimate TIN Nodes tool.

Greetings, See Zonal Statistics as Table.  You can use this tool to get the mean value per zone (polygon). Regards, Eric ... View more

Hi Marie, Both of the tools I mentioned honor the Mask Environment Setting.  You can set your polygon as the mask.  Alternatively, you can Clip the data using your shape to create a subset, then perform any additional processing on the smaller dataset. Regards, Eric ... View more

Ben, If your polylines are 3d lines, then you can run Add Z Information.  If your polylines are 2d, and you have a DEM (which you do), then you can run Add Surface Information.  Both tools require a 3D Analyst license. Regards, Eric ... View more

Greetings, Are you referring to this? http://arcscripts.esri.com/details.asp?dbid=13307 Installation: Unzip the "Spatial_Analyst_Plus.dll" file somewhere on your system. Start ArcMap and go to the "Tools -> Customise Dialog" Click the "Add from File" button and select the "Spatial_Analyst_Plus.dll" - this can take a long time to load the first time so be patient - up to a minute on my machine. A "Spatial Analyst Plus" item will be added to the Toolbars tab. Check this and click close. The Spatial Analyst Plus Toolbar should now be visible Do you have a license for Spatial Analyst?  Is it installed? Is it activated?  Spatial Analyst PLUS is 3rd party. It relies on Esri's Spatial Analyst product being installed and licensed.  Regards, Eric ... View more
