1.  What version of ArcMap, including service packs, are you running?  Ex:  ArcGIS 10.1 Service Pack 1 2.  What type of geodatabase does your mosaic dataset reside in (i.e. File, Personal, SDE)? 3.  Try rebuilding the overviews with only the options 'Define Missing Overview Tiles' and 'Generate Overviews'.  Make sure the options 'Generate Missing Overview Tiles' and 'Regenerate Stale Overview Tiles are unchecked. ...

Thanks for the data, but I could not reproduce this error. 1.  What version of ArcGIS, including Service Packs are you running?  i.e. ArcGIS 10.1 SP1 2.  If you copy these two excel files to a new directory, so the code is only iterating through these two files, do you still receive the error? ...

This is most likely a problem with the XLS file.  Would you be able to upload the file, or a portion of it if it's too large? Also, when posting code, be sure to wrap it in tags using the # tool above.  This will preserve the format/identation. ... View more

You can extract the endpoints from lines using the Feature Vertices to Points tool.  Choose the option BOTH_ENDS for the Point Type. ... View more

The Raster to Point tool is the easiest way to convert a raster to point elevation.  The Extract Values to Points tool will extract values from an underlying elevation raster to an existing points feature class/shapefile. If you have 3D Analyst, you can use the Interpolate Shape tool to convert your line to 3D based off of an elevation raster.  There is an option within this tool for the interpolation to use the input vertex locations. ...

Hi Colleen, 1.  Does this occur for all polygon feature classes, or just one in particular? 2.  Do you have any service packs installed?  I would recommend installing SP5 if you haven't already. ... View more

Hi Greg, Try the following instead: dojo.require("esri.map"); dojo.require("esri.arcgis.utils"); var map, maxExtent,iniExtent, tiledMapServiceLayer;      function init() {     // configure the proxy URL -- required to access Data not on the local server     esri.config.defaults.io.proxyUrl = "/proxy/proxy.ashx";     var lods = [ {"level" : 6, "resolution" : 2445.98490512499, "scale" : 9244648.868618},                      {"level" : 7, "resolution" : 1222.99245256249, "scale" : 4622324.434309},                      {"level" : 8, "resolution" : 611.49622628138, "scale" : 2311162.217155},                      {"level" : 9, "resolution" : 305.748113140558, "scale" : 1155581.108577},];             var webmap = "longwebmapstring"     iniExtent = new esri.geometry.Extent({"xmin": -7315000, "ymin": 5829000, "xmax": -4967000, "ymax": 6836000, "spatialReference":{"wkid":102100}});     mapDeferred = esri.arcgis.utils.createMap(webmap, "map", {         mapOptions: {             extent:iniExtent,             lods: lods,                         slider: true,             sliderStyle: "small",                         nav:false           }});                         mapDeferred.addCallback(function (response) {             var map = response.map;             dojo.connect(map, "onExtentChange", checkExtents);         });     }   function checkExtents(map){     console.log("checkExtents called");         var extent = "";      extent = "XMin: "+ map.xmin.toFixed(4) + " "            +"YMin: " + map.ymin.toFixed(4) + " "            +"XMax: " + map.xmax.toFixed(4) + " "            +"YMax: " + map.ymax.toFixed(4);                console.log(extent); }         dojo.ready(init); ...

I am assumming the raster datasets are floating point rasters, and therefore do not have an associated attribute table.  Do you have the 3D Analyst extension?  If you do, you can use the Raster Domain tool to create a single polygon feature class of the raster boundary.  Then, if you have the Spatial Analyst extension, you can use the Zonal Statistics as Table tool.  Use the output from the Raster Domain tool for the input features, specify your raster dataset, choose an output table, check 'Ignore NoData in calculations', and specify ALL for the Statistics Type.  The output table will have a COUNT field which contains how many pixels (excluding NoDATA) are within your raster dataset. ...
