Greetings, There are couple things missing from the workflow, so I don't know exactly how you are importing the model.  The thing to keep in mind is that mutltipatches in a shapefile do not support textures.  Only multipatches in a geodatabase support them. Best, Eric ... View more

It's under consideration for a future release. Best, Eric ... View more

Go to the layer properties > symbology tab. Hit the Add button on the left. The Add Renderer dialog will open. Add something like 'Face slope with graduated color ramp'. The other people who reported the issue indicated it was a problem only with 'Face elevation with graduated color ramp'. At least that was my understanding. I didn't submit the defect or work directly with the customers except via forum. The issue eventually made its way to our Support staff would looked into it and found a way to repro using ATI hardware. Don't forget to turn off the elevation renderer. Best, Eric ... View more

Greetings, The Kriging tool from Spatial Analyst honors the Mask setting in the environments.  So, you can set the country of Thailand for the Mask, rather than using it for Processing Extent.  The Processing Extent will still produce a square result that doesn't comform to a nations border (an irregular shape). Environment Settings > Raster Analysis > Mask Since you have a worldwide dataset for countries, you can just select Thailand, then right click the layer in the TOC, and choose Data > Export Data - Export just the selected record.  Use this new layer for the mask. What version are you using? Note, if you don't want to redo the Kriging because it possibly takes a long time to complete, you can just take the result you have, and the newly created Thailand layer, and run Extract by Mask.

Jamal, Your request will definitely be considered for some future version.  It turns out there are some ideas already floating around for zooming to pixels, although not quite like you (from a table selection).  Thanks for the feedback. Best, Eric ... View more

Hi Mark, If you change the renderer to something other than elevation does it speed up the display?  I have a hunch you are encountering a bug that was logged recently.  See this thread, as it pertains to ATI cards. http://forums.arcgis.com/threads/63443-ArcScene-10.1-near-non-functional-with-TIN-(face-elevation) NIM085208: In machines with ATI Graphic Cards, ArcScene freezes or takes very long to display a TIN surface as face elevation with graduated color ramp.

Hi Jamal, Zoom To Selected is short for Zoom to Selected Features. Using your screenshot in the original post, what would you have us do if you selected value = 2? There are 25551 pixels. Where do you want us to zoom? The rows in a raster attribute table are not like rows of discrete features in a feature class, nor is there a shape field containing geometry for easy query. It's not like there is a property within a raster dataset that stores the minimum bounding geometry for each value in the raster that could be used as a zoom extent. The case where the count is 1 is the only time you have a discrete record in a raster attribute table. I would argue its quite uncommon from all the data I've seen over the years. Zooming to selected pixels would have to make sense for all cases to even be considered. There are multiple ways to 'find' this pixel. 1. As stated earlier, convert to features. 2. Create a new raster with just that one pixel. There are several ways to do this one. Raster calculator, conditional statements, or if you want to make it easy just use Extract by Attribute from spatial analyst. Best, Eric ... View more

Greetings, When you create the LAS dataset, there is a parameter in the tool called Coordinate System.  If no spatial reference is explicitly assigned, the LAS dataset will use the coordinate system of the first input LAS file. If the input files do not contain any spatial reference information and the Input Coordinate System is not set, then the LAS dataset's coordinate system will be listed as unknown.  If you forget to set the parameter and the .las files don't contain any spatial reference information, you can go into the LAS datasets properties and go to the XY Coordinate System tab and set it after the fact. You can not reproject a LAS dataset at this time.  Here are some LAS dataset considerations, with spatial reference being one of them... Best Regards, Eric ... View more

Sara, What tool is having a problem with 112,000 points? I routinely work with tens of millions of points, sometimes billions. Best, Eric ... View more

Very good redirect, Mark.  James,  the thing to take away from that pdf in the other thread is that kriging is not an exact interpolator.  The values can exceed the input range, and the surface created will not pass through the sample points. Best, Eric ... View more

Maps units are meaningless to analysis. Check you input coordinate system.  It's probably geographic so you can't put something like 100 (dd) and expect reasonable results. Project your input, or set the Output Coordinate System in the environment settings to something that uses units of feet/meters. Best, Eric ... View more

That looks like a display issue. Check the resampling on each in the layer properties. I bet one is nearest neighbor (the blocky one), and one is bilinear. Another way to see if you got different answers is to just subtract one from the other. You should get all zero's. Best, Eric ... View more

Greetings, It's easiest to put your landsat images into a mosaic dataset, then insert the function. Please read the information on the Tasseled Cap Function for usage tips. I provided a screenshot of where the function exists. Best, Eric ... View more

Your polygons are converted to raster internally at the same resolution of the value raster. Here is the documentation for the tool. Zonal Statistics as Table Relevant parts: If the zone input is a feature dataset with relatively small features, keep in mind that the resolution of the information needs to be appropriate relative to the resolution of the value raster. If the areas of single features are similar to or smaller than the area of single cells in the value raster, in the feature-to-raster conversion some of these zones may not be represented. To demonstrate this, try converting the feature dataset to a raster with the appropriate feature-to-raster conversion tool and specify the resolution to be that of the Value raster. The result from this conversion will give an indication about what the default output of the zonal operation will be. If you have fewer results in the output than you may have expected, you need to determine an appropriate raster resolution that will represent the detail of your feature input, and use this resolution as the Cell Size of the Raster Analysis Settings of the Environment.
