You could use the Zonal Statistics as a table tool to obtain many statistics about the polygons based on the underlying raster.  You can then take the table and join it back to the polygon feature class. ... View more

To display the pipes in 3d there is information about creating the multipatch pipes here.   What you will want to do is use ArcScene to display the lines and then use the option to select Multiple Attributes to display the layer as a cylinder and then select the attribute for size and display that.  Once you have the display as desired, use the Layer to 3d Feature Class to make it a multipatch. ...

Not a problem Wilbert!  I am glad that the uninstall worked for you.  I encourage forum posters, who have maintenance to make an incident with Support.  We are here to help speed you along, so rather than frantically posting in forums, for individual help, make a Support Incident and get your very own Analyst to help with your particular issue. ...

Per the help documentation, it is recommended that you, When using commercial NITF imagery, such as Quickbird, GeoEye, IKONOS, WorldView-1, WorldView-2, or RapidEye, you will want to first ingest one image into the mosaic dataset using the NITF raster type. This will create a mosaic dataset using the NITF fields. Then use the sensor-specific raster type to add the remaining imagery. When the first image is added it will create the NITF fields, any subsequent additions of imagery will populate the fields accordingly. So in this workflow, you should add one raster as a NITF and then it should work once the fields are set.  Within the Worldviews properties, there is an option to select the bands that you are looking to add.   [ATTACH=CONFIG]13986[/ATTACH] Also if you prefer to add them all and only choose the ones to display there is the Extract Bands Function. ...

There is help documentation on the subject of how a raster is stored that is good reading prior to making a decision.  Depending on the version of software you are using, I would consider 3 factors: 1. Is data storage size an issue? 2. What is the final client you want the rasters displayed in? 3. Who will be accessing the data? If you are using ArcGIS 10, I would strongly consider the mosaic dataset as an option, to retain the original native format and increase the performance.  However, if you are using another version or are seeking a specific client then I would consider the SDE.  If you plan on publishing the raster, then you will have to look into the necessary licensing for publishing a mosaic dataset vs publishing the raster via SDE.  If you are concerned about the look of the SDE raster, be sure the cell size, resampling display and pyramid resampling match the original raster.  That may be causing the issue to make it 'bad.' ...

With the spot heights, you could use that information and apply that information to the point files in order to create mass points that could be used for the interpolation and then use the stream if it is 3d as a breakline, but it seems like you are working this backwards.  You have all of the DEM products but not the DEM.  The contours, spot elevations, and hillshade are all derived from the DEM.  If you had the contours you could use the Topo To Raster tool and then derive a DEM from that.  You may take a look at the USGS Seamless site to download a DEM for your area. ...

There is a tool in 10.1 called the Stack Profile tool.  This tool will create the desired effect. ... View more

There is a tool called LAStools that should be able to help with the conversion to LAS.  There is an enhancement request mentioned here for the same behavior in ArcMap.  After you have the points in LAS, then you will need to utilize 10.1 to take advantage of the functionality to set the codes for the individual points with the Set LAS Code Class with a Feature Tool. ...

There is no direct conversion from Multipatch to TIN.  What I was trying to emphasize earlier is that you can use the multipatch you create in some of the 3d tools.  There is an ArcScript Tool and an enhancement request that is currently among the ideas to be considered in the future.  Currently you cannot do it with out of the box tools. ...

Import 3d Files will read a .3ds file and then convert it into a multipatch file.  You can then use the multipatch file in 3d analysis in ArcMap, but there is not direct conversion to these formats. ... View more

Since you said Lidar from ascii points, it may be rather difficult since you did not mention LAS format.  If you had the LAS format and if it was classified, you would just need to select the proper class.  Since it may not be LAS and it may not be classified, you may have to look to other means of selecting points. In ArcGIS with LAS data, you can use the information on the LAS to Multipoint tool to select the proper class.  Otherwise, you face the daunting prospect of having to manually classify the data.  There are additional tools at 10.1 to help you classify them, but they require the data to be in the LAS format. ...

If you are georeferencing them to the same coordinate system and choosing the option to 'Rectify' instead of 'Updating the Georeferencing,' then you should have created new rasters that have been resampled and should be 'oriented' the same way.  It sounds as if you may have updated the georeferencing or perhaps have them all georeferenced in the same MXD.  I would be sure they are rectified into the same coordinate system and then you should not have mis aligned pixels. ...

I would consider the Zonal Statistics as a Table tool.  Specify the Zone Layer as the polygon file with the field of the land cover and then specify the value raster as the one you would like to survey.  The output will be in a table,which you should be able to join back to your original feature class.  Area is one of the statistics generated. ...

There is some information here about subsurface modeling here.  There is also further discussion about it here on the forums and a video here.  To obtain the angled nature, you may consider trying to generate the model as a series of points or convert to a line, rather than try to force the extruded point to angle a certain way. ...
