Setting up Metadata Transfer…After the Fact

What’s that?  Went out in the field and collected a bunch of data but forgot to set your GNSS metadata transfer fields from the desktop before you went out?  Not a problem…this can be done completely after the fact as these values aren’t populated until you ‘Update Features’ after performing your post processing.  Remember that for point features you have two pieces of information available: Horizontal Estimated Accuracy (m) and Height Above Ellipsoid (m).  For line and polygon features you only have one: Horizontal Estimated Accuracy (m).

For the purpose of this post, we’re going to assume that you’ve already collected and post processed data and have one or more sessions in a Trimble Positions project.

For ArcGIS for Windows Mobile projects:

  1. Add new fields to the feature classes in the geodatabase (data type = double) to store the GNSS metadata, if you don’t have them already.  This can be done from ArcCatalog or from the Catalog window in ArcMap.
  2. Create a new mobile cache (or update your mobile service) that contains these new fields.
  3. If using a mobile cache, navigate to the folder where you’ve stored your mobile project (in Mobile Project Center) and replace the cache folder with the new one.
  4. Open up Mobile Project Center and open your previously saved mobile project. The schema will be updated with the new fields.
  5. Select the layer you wish to set GNSS metadata fields for.
  6. Select the ‘Fields’ tab at right and select the desired field for GNSS metadata.
  7. Scroll down to the ‘Auto Fill’ section and select one of the two Trimble Positions entries in the ‘While Updating’ drop down. Select the same value for both ‘While Updating’ and ‘While Collecting’.  The two Trimble Positions auto fill entries will only appear in the drop down for fields with the appropriate data type.
  8. Repeat for additional metadata fields and layers.
  9. Save the project from Mobile Project Center.
  10. Open up ArcMap and open the map document that you used for your mobile project.  If the Trimble Positions project did not automatically load (e.g., if the MXD is not linked), open it using the ‘Projects’ functionality in the Administration window of Trimble Positions Desktop add-in.  Note: If you had the project open this whole time, you will need to re-load it either by closing and re-opening ArcMap or switching to a different MXD and then back.
  11. Select the desired session in the dockable window and click ‘Update Features’.  This will post (or re-post) the updated geometries and GNSS metadata to your feature classes.

For ArcPad projects:

  1. Add new fields to the feature classes in the geodatabase (data type = double) to store the GNSS metadata, if you don’t have them already.
  2. Open up ArcMap and open the map document that you used for your ArcPad project.
  3. Using the ‘Projects’ functionality in the Administration window of Trimble Positions Desktop add-in, select the desired project and click ‘Edit…’.
  4. In the ‘Edit Layer Metadata’ dialog, select the desired layer and choose the fields for GNSS metadata.  Only fields of the appropriate data type will be displayed in the drop down.
  5. Repeat for additional layers as necessary and click ‘Finish’ when done.  The Administration window can also be closed.
  6. Re-load the ArcPad project in Trimble Positions by either closing and re-opening ArcMap or switching to a different MXD and back.  Use the ‘Projects’ functionality in the Administration window if your project does not automatically load.
  7. Select the desired session in the dockable window and click ‘Update Features’.  This will post (or re-post) the updated geometries and GNSS metadata to your feature classes.
