Measurement Issues with Buffering Polygons

Permanently deleted user

Has anyone experienced measurement issues when buffering lines and polygons in Essentials Viewer.  For example, when doing a buffered identity with a line or polygon, my distance options are degrees or radians.

(/customer/servlet/servlet.FileDownload?file=00P6000000e88WAEAY) /customer/servlet/servlet.FileDownload?file=00P6000000e88WAEAY

However, when doing a buffered identity with a point, my distance options are feet, yards, metres, kilometres, miles, natautical miles.

/customer/servlet/servlet.FileDownload?file=00P6000000em1eGEAQ

I would prefer my distance units for line and polygon buffers to be the same as that for points (feet, yards, metres, kilometres, miles, nautical miles)

I am using WKID 2193 (NZTM2000) and have set the measurement units to be metres for distance, hectares for area, WKID 2193 and projection units as metres.

/customer/servlet/servlet.FileDownload?file=00P6000000e88WFEAY

And I have set up a geometry server as well.

/customer/servlet/servlet.FileDownload?file=00P6000000em1j6EAA

What else can I do?

Your help would be appreicated.

Thank you

Regards

Dianne

  Hi Nico,

  No, I haven't found a solution for this issue.  The issue is still present in version 4.1.

  Hi All,

  I just had the same problem and after talking to Ralph found that the following fixed pretty much all of my problems, some of which I already had either in place or documented.

   

  I believe the bit that ultimately fixed it was the WKT section but the rest gives some other niceties.

   

  Set the GIS Services -> Geometry Service URL to:

   

  http:// <ArcGIS Server Name>/arcgis/rest/services/Utilities/Geometry/GeometryServer

   

  Set the WKID in Tool Behavior section of the viewer to:

   

  2193

   

  Set the WKT in Tool Behaviour section of the viewer to:

   

  PROJCS["NZGD2000 / New Zealand Transverse Mercator 2000",GEOGCS["NZGD2000",DATUM["D_NZGD_2000",SPHEROID["GRS_1980",6378137,298.257222101]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse_Mercator"],PARAMETER["latitude_of_origin",0],PARAMETER["central_meridian",173],PARAMETER["scale_factor",0.9996],PARAMETER["false_easting",1600000],PARAMETER["false_northing",10000000],UNIT["Meter",1]]

   

  Edit C:\Program Files (x86)\Latitude Geographics\Geocortex Essentials\Default\REST Elements\Sites\ <Site Name>\Viewers\ <Viewer Name>\VirtualDirectory\Config\Viewer.xml and put in the following somewhere inside the <Modules> section - in my case I put it after </Toolbar>:

      <Measurement>

   

        <Views>

   

          <View Region="MeasurementToolsRegion" />

   

        </Views>

   

        <Configuration GeometryServiceUri="{GeometryServiceUri}">

   

          <MeasurementOptions DefaultUnit="meters" OverrideUnits="{MeasurementOverrideUnits}" PredictionEnabled="{MeasurementPredictionEnabled}" />

   

          <Projection Wkid="2193" ProjectionUnits="meters" />

   

        </Configuration>

   

      </Measurement>

   

      <CoordinateTool>

   

        <Views>

   

          <View Region="CoordinateToolsRegion" Type="Geocortex.EssentialsSilverlightViewer.CoreModules.CoordinateTool.CoordinateToolView" />

   

          <View Id="CustomCoordinateView" Region="ModalWindowRegion" Type="Geocortex.EssentialsSilverlightViewer.CoreModules.CoordinateTool.CustomCoordinateView" Visible="false" />

   

          <View Id="MouseCoordinatesView" Region="CoordinatesRegion" Type="Geocortex.EssentialsSilverlightViewer.CoreModules.CoordinateTool.CoordinatesView" Visible="{MouseCoordinatesShow}" />

   

        </Views>

   

        <Configuration ShowCoordinatesEnabledbyDefault="True" GeometryServiceUri="{GeometryServiceUri}">

   

          <CoordinateSystems>

   

            <CoordinateSystem DisplayName="NZTM" WKID="2193" NumDigits="3" DisplayAsDMS="false" DisplayAsLatLon="false" />

   

            <CoordinateSystem DisplayName="NZMG" WKID="27200" NumDigits="3" DisplayAsDMS="false" DisplayAsLatLon="false" />

   

            <CoordinateSystem DisplayName="Web Mercator" WKID="102100" NumDigits="6" DisplayAsDMS="false" DisplayAsLatLon="false" />

   

            <CoordinateSystem DisplayName="Lat/Lon (DD)" WKID="4326" NumDigits="4" DisplayAsDMS="false" DisplayAsLatLon="true" />

   

            <CoordinateSystem DisplayName="Lat/Lon (DMS)" WKID="4326" NumDigits="4" DisplayAsDMS="true" DisplayAsLatLon="false" />

   

          </CoordinateSystems>

   

        </Configuration>

   

      </CoordinateTool>

   

  Cheers, Brett
