Janice,

Please refer to this for additional information on the VRT format.

Thanks, I'll give this a try. Also, does a specification exist for the VRT file? (Helpful for instances where I have a different LayerSRS, geometryField encoding, etc.) The Bentley Map manual just gives the same example you posted here.

So you will need to set up a VRT file to do the import and then reference this file in the interoperability interface.

Creating a VRT file

A VRT file is a text file that describes the feature name, the file name, the layer

type (in this case a point layer), the spatial reference system, and the names of

the columns in which to find the X and Y (and optionally Z) values.

A sample VRT file to import data from a CSV file is shown below.

<GeometryType>wkbPoint</GeometryType>

</OGRVRTLayer>

</OGRVRTDataSource>

Pat attention to the GeometryField, LayerSRS and the SrcDataSource tags.

Then set up the PBA string as you normally would do in the interoperability interface for the import.

The file is in .xyz format (x,y,depth). It is a comma-delimited file, like .csv but with a different file extension. Sebastian, I had tried loading the file via the Interoperability Dialog (I know you can set PBA there) but I receive the following error message once I select the file:

Are there any other options for loading a file in this (.xyz) format and defining PBA?

What is the source of your data ?

Hi,

In the Interoperability dialog, in addition to the symbology options, you can define a literal or a PBA.

Please refer to Bentley Map Help file by clicking to the following link: docs.bentley.com/.../MicroStationMaphelp58.html
