Exporting Shapefiles from Georeferenced Files

[lisagravy 32]

I'm having issues exporting shapefiles from VW2020 files which have the geo-referencing settings switched on as default.

 

If I select a simple polygon within a georeferenced / geolocated file, and navigate to File > Export > Export Shapefile; I typically then would choose selected objects, keep projection, and write .prj file (and choose all additional object data). When I do this and click OK, I am prompted where to save the file, and click OK again. Nothing happens, and no file is generated. 

 

What I'm having to do as a workaround is open a new file, turn off all the geo-referencing settings, copy / paste in place my polygon to the corresponding X Y location to the co-ordinate position, and then go through these steps again for a shape file to actually output? Is this a bug or is there a flaw in my workflow somewhere?

Again, I will look into this for you Lisa!

Thanks Tamsin 😳

Have seminar to present early afternoon, then I'm onto this one!

OK - I tested this as follows:

1. Created a file with UK georeferencing.
2. I used the Geolocate tool to search for my home postcode and place the internal origin in my street.
3. I selected the single design layer and georeferenced it to match the document.
4. I then used the option to Align User Origin with Georeferenced Coordinate System.
5. I then used the Geoimage tool to create an image of my street.
6. I traced over the roads with polygons, and added a record that included the street name.
7. I traced over some houses and added a record which categorised the size of house and the poshness vs normalness of the occupants (! - well, it IS Friday).
8. I added a GIS Stake close by, and adjusted its X and Y to give me an easy to remember whole number on the E and N.
9. I then used the Geolocate tool to move the internal origin to the point of this stake. (I did this to help me ensure that the resulting shapefiles ended up in the correct location).
10. I then exported the files, by record. I re-ran the export for each type of record, including the Stake record, so that I would have all the geometry and that all important coordination point. 
11. This seemed to work just fine.

I then imported the shapefiles into a blank document, and had the import process georeference the document according to the shapefile. Everything ended up in the correct place. A Stake placed over the 3D Locus designating my original stake point, showed the correct Easting and Northing. The only thing I had to do was use Geolocate to move the internal origin to my known point (the stake), just for completeness. As we learnt from the Design Layer Viewport referencing of GIS data, the location of the internal origin is important and needs to be consistent for coordinating across files.

 

Now, I will test the export using the selection option instead of exporting everything by record...

 

(P.S. Can't share my files on this one, as my neighbours might take exception to their posh vs normal classification!)

Seems to be working fine. I'll give you a call next week and we can talk through what's going wrong for you.

@Tamsin Slatter I LOVE the poshness v normalness classification! 😂

 

Weird you can get it to work. I've tried on both my machine and a colleague's, and when I hit OK to export the shapefile, the dialogue box goes away but no shapefile is ever created? Can chat next week, I'll maybe send you a basic test file! None of my tests are as fancy as yours though, literally just using a single polygon.

 

Have a good weekend, and thanks very much for all your help on this!! Really excited to roll it out as our new workflow ☺️

Hi Lisa

Do send me a file and I'll be happy to take a look. I've tested in SP1 and SP2 and all is good for me.
