I am editing metadata via a VB.NET Addin. Update information comes from ASCII files and I am and looking for a way to insert new lines. In this simple example the ASCII text provided might look like: "Administrator: Person A"  Using the IXmlPropertySet2 interfacemy code looks something like this: Dim sName As String = "mdContact/rpPosName" Dim sValue As Object = "Administrator:  \r\n  Person A"            'update string with escape sequence added XmlPropertySet2.SetPropertyX(sName, sValue, esriXmlPropertyType.esriXPTText,  esriXmlSetPropertyAction.esriXSPAAddOrReplace, False) Setting the property type to esriXPTText suggests that the value parameter (sValue in this example) should be a string. However any escape characters inserted in the string are not interpreted correctly and instead are shown as normal text in the metadata viewer. Being at a loss what the correct escape character might be I tried quite a variety: <\r\n>    &lt;br&gt;,    &#013;   &#10;  <br>  \r\n I have seen the somewhat similar thread     https://community.esri.com/thread/213315-new-line-in-metadata-summary-description but this does not fit my problem. Any ideas how to insert new lines? ... View more

I have been loading a DEM (.img file). It displays alright but when changing vertical exaggeration nothing happens. Is there anything else to do to make vertical exaggeration work? Thanks, Axel ... View more

I need to recreate the functionality of the link table in the georeferencing toolbar. I have sets of ground control points (usually between 5 to 30 gcps for an image) and need the resulting RMS errors for a given transformation - there is no need to actually rectify the images. I have trouble understanding the DefineFromControlPoints Method. The documentation says. 'Defines the best affine transformation between two sets of points' but the arguments are defined as        ByRef fromPoints As IPoint which I understand is one point, not a set of points. This sample (rather old, but one of the few available I found) http://edndoc.esri.com/arcobjects/9.1/ComponentHelp/esriGeometry/DefineFromControlPoints_Example.htm states pAffineTrans2D.DefineFromControlPoints 4, pPtFrom(0), pPtTo(0) which appear to be single points from a point array, so again actually only one ground control point. I am confused... So again my question: can anybody show me how to use a set of points with DefineFromControlPoints ? Any help is appreciated! Cheers Axel ByRef fromPoints As IPoint ... View more

Hi all, when georeferencing a raster data set t he standard link table saves only coordinates. Residuals and errors are shown but are not saved in the link table. Is there a way to export a link table including RMS errors? Thanks in advance Axel ... View more
