Is there a way to get the actual longitude coordinate of a point selected on a map, when a map is panned across the wrap?  Or, do you have to calculate the math manually? IOW, if a user pans to the left and picks a point say around Vancouver (which is actually: -123, 49), the mapPoint.x reports -483.  The math is simple enough I suppose, but is there a way to extract the actual coordinate.

Hello, I have a mosaic raster dataset of surface elevation data.  If I use the Image Analysis window with this dataset and create a hillshade image, it works great. However, if I try to add the Hillshade Function to the mosaic dataset itself, the result is a black image?  I've tried re-calculating statistics after this function was added and the result is the same, black image. Any ideas/suggestions would be greatly appreciated. Warren M ... View more

Hello all, I'm creating an app based on the Clustermap sample by globoserver.  The sample is working great and I've managed to implement a filtering mechanism.  The problem I'm struggling with is trapping an error when no results are returned.  It seems like the error function is not being called? dojo.connect(queryTask, "onError", function(err) { alert("CUSTOM ERROR: " + err.details); }); Any ideas/suggestions would be greatly appreciated.

Hello, I am trying to update Map Document Properties, but am struggling with the syntax for a carriage return/ line feed in the description property. If I use the Python window I can retrieve the description property and it looks something like this: >>> mxd.description u'Test Line 1\r\nTest Line 2' If I set the description property with the Python window with the following string: >>> mxd.description='New Line 1\r\nNew Line 2' It works as expected. However, if I try to specify that same string via a script parameter it adds an extra '\' and looks like: u'Test Line 1\\r\\nTest Line 2' Any ideas/suggestions would be greatly appreciated. Thanks!

Hello all, I have some simple point data in an ArcSDE geodatabase, I have published the data to ArcGIS Server, and I'm getting my feet wet with the JavaScript API. Using the samples provided, and substituting my FeatureServers, I can get updates and deletes to work fine, but adds (inserts) do not work. The response to the applyEdits on an insert is: {"addResults":[{"objectId":-1,"globalId" : null,"success":false,"error":{"code":-2147216100,"description":"Error while inserting populated row into Insert Cursor"}}],"updateResults":[],"deleteResults":[]} Any suggestions would be greatly appreciated.

Hello, I would like to enable a tooltip/maptip when a user hovers over a feature, but then I would like to enable an edit function when the user selects the feature. All of the samples seem to show one or the other method, so I'm wondering if this is possible, and/or, if there are better design options for something like this? Thanks so much, Warren M ...

Hello, I'm trying to determine what is the best tool to accomplish a particular task, and I need help... Scenario: Type of work: Geo-envirnomental planning Say I have original ground 'surface' data in LIDAR, and I need to place create a dam.  I have a polyline representing the top of the dam, and it is 'floating' above the surface at the correct final elevation. Based on this info, can ArcGIS: Create the dam by projecting the polyline (or lines) down to the OG surface at a specific slope, ie 3:1? Calculate the volume of the dam Extract the dam footprint Visualize the dam in 3D I have 3D Analyst, and Spatial Analyst, and I understand functional surfaces (2.5D) and tins in Arc.  I know how to accomplish this is other 3D modeling/CAD packages, so I guess I'm just not clear if, or how, Arc can handle the above scenario. Thanks for any info provided. Warren M ... View more

I have some general comments and questions about transparency and fills in ArcGIS: Why can't you just set transparency on the fill area of a polygon?  I don't want the boundary transparent as well.  Yes, I know it's easy enough to simply copy the layer, and turn of the fill and transparency on the copy, but seems silly to have to do that. With overlapping polygons in a single feature class, many times the transparency fails to show lines underneath of the overlapped polygon? Unless I'm missing something, it seems to me that Arc* does not do a 'true' transparency?  For example, if I have overlapping polygons, the overlapped area should be 'darker' because of 2 overlapping/stacked objects, but that's not what I'm seeing. Unfortunately, the forum is not letting me upload an image, so I cannot provide a sample screen capture. Any suggestions/comments greatly appreciated Warren M ... View more
