I am working on an add-in for the ArcGIS Explorer Desktop mapping client and need to take Lon/Lat coodinates and display them in an MGRS formatted string in a Note or MessageBox. Ideally, Lon/Lat (0, 51.4791) would end up being displayed as MGRS 31UBT9168707373 I used sample code from the ArcGIS Resource Center, shown below, but when I do a ToString on the resulting point in the first code sample using the Geographic Coordinate System, I get: resultString = "Point: X = 0 Y = 51.4791000009189" (obviously the original Lon/Lat) In the second code sample using the Projected Coordinate System, I get: resultString1 = "Point: X = -538880.521630103 Y = 5810593.60821005" (something entirely different, but not the final solution) What do I need to do to end up with the string "31UBT9168707373"? Thanks for any help! First code sample:   // Create a Point at Greenwich, UK. By default new Geometries have the WGS 1984 geographical coordinate system.   ESRI.ArcGISExplorer.Geometry.Point projectPoint1 = new ESRI.ArcGISExplorer.Geometry.Point(0, 51.4791);     // Create an instance of the CoordinateSystem we want to project the Point into.   CoordinateSystem projectIntoHTRS96 = CoordinateSystem.GeographicCoordinateSystems.Europe.HTRS96;     // Retrieve suitable transformations between the two coordinate systems.   System.Collections.Generic.IList<GeographicTransformation> suitableTrans1 = GeographicTransformation.GetTransformations(projectPoint1.CoordinateSystem, projectIntoHTRS96);   ESRI.ArcGISExplorer.Geometry.Point outputPoint1 = null;   // For brevity here, simply pick the first suitable transformation.   GeographicTransformation geoT1 = suitableTrans1[0];   // Project the point using the selected transformation. Cast back to a Point - Project does   // not change the type of Geometry.   outputPoint1 = GeometryOperations.Project(projectPoint1, projectIntoHTRS96, geoT1) as ESRI.ArcGISExplorer.Geometry.Point;   String resultString = outputPoint1.ToString(); Second code sample:    // Create an instance of the CoordinateSystem we want to project the Point into.   CoordinateSystem projectIntoHTRS96Z = CoordinateSystem.ProjectedCoordinateSystems.UTM.Europe.HTRS96UTMZone33N;     // Retrieve suitable transformations between the two coordinate systems.   System.Collections.Generic.IList<GeographicTransformation> suitableTransZ = GeographicTransformation.GetTransformations(projectPoint1.CoordinateSystem, projectIntoHTRS96Z);   ESRI.ArcGISExplorer.Geometry.Point outputPointZ = null;   // For brevity here, simply pick the first suitable transformation.   GeographicTransformation geoTZ = suitableTransZ[0];   // Project the point using the selected transformation. Cast back to a Point - Project does   // not change the type of Geometry.   outputPointZ = GeometryOperations.Project(projectPoint1, projectIntoHTRS96Z, geoTZ) as ESRI.ArcGISExplorer.Geometry.Point;   String resultString1 = outputPointZ.ToString(); Other notes: I was hoping for: MGRS 31UBT9168707373 geoT1 and geoTZ are both = {HTRS96_To_WGS_1984_1} _core = {ESRI.ArcGISExplorer.Internal.WrapperCore<ESRI::ArcGISExplorer::Geometry::GeographicTransformation>} Name = "HTRS96_To_WGS_1984_1" projectIntoHTRS96 = {GCS_HTRS96 (4761)} resultString = "Point: X = 0 Y = 51.4791000009189" projectIntoHTRS96Z = {HTRS96_UTM_Zone_33N (3767)} resultString1 = "Point: X = -538880.521630103 Y = 5810593.60821005" ...

I am using a NetworkLink to dynamically update a map.  So far, I am only able to get Point coordinates to change properly.  I need to be able to update the coordinates of a LineString as well as a Polygon.  Create and Delete updates work fine, but the Change does not.  Here is my "Change" kml.  I've ensured that the targetHref and the targetId are both correct. Any ideas?  Does ArcGIS Explorer support updating things other than points?  Any help would be appreciated. <?xml version="1.0" encoding="UTF-8"?> <kml xmlns="http://www.opengis.net/kml/2.2">    <NetworkLinkControl>       <cookie>cookie=CookieFrom2</cookie>       <linkName>Enable Updates</linkName>       <Update>          <targetHref>http://192.168.128.208:7003/MoveEmptyTrackList.kml</targetHref>          <Change>             <LineString targetId="MTG_Track_01_01">                <coordinates>                   -90.88,35.00,363 -89.64,34.58,363                </coordinates>             </LineString>         </Change>       </Update>    </NetworkLinkControl> </kml> ...

I need an outbound connector that works similar to the Publish GeoEvents on a REST endpoint, but I need to produce KML that supports MultiGeometry with a LineString for each GeoEvent.  Since I have not found a way to do this with the connector, I am willing to build my own outbound connector.  I have found little to no documentation on how to create an outbound adaptor.  I have a set of example bundles, but they are processor or inbound.  I need better documentation and or several connector examples.  Any help, Please?

I am new to ArcGIS and can't find an exact answer to my problem. I developing a mapping solution that runs in a closed network.  Where do I get some world maps for prototyping that don't link to the internet? Thanks, Ken ... View more

I am new to ESRi products and also starting a new project that displays a significant amount of data on a map that updates once a second.  For most of the dynamic features, once added they don't change.    Is there pattern than allows me to query changes since the previous query and then update the JMap.  In my limited experiments, I was not able to query and process thousands features every second, but if I could restrict the processing to the changes, it should work. Constraints: 1. I would like to use the ArcGIS Runtime SDK for Java to allow integration into our current product-line.   2. Out product is often delivered to a closed environment, thus ArcGIS online is not an option. 3. With this amount of data, I am sure that the zoom level will have to effect the data shown, but I would like to determine those constraints once I have the best real-time pattern implemented. 4. I am also exploring the GeoEvent Processor for data insertion into ArcGIS Server. If I am heading down the wrong trail, point me to the right direction. ... View more
