[Gvsig_english] New User -problems withsplitting geometries andattributes.

Hello,

As Wolfgang said, your shapefile contains 3D linestrings. Unfortunately, some parts of gvSIG are still written as if 3D geometries did not exist. I have sent a bug report and a patch to try to solve this. Hopefully this patch will be applied soon.

I cannot think of a way to find out in gvSIG if a layer contains 3D geometries. The software used by Wolfgang to convert it can be downloaded from http://fwtools.maptools.org and includes also a command-line program that will tell you if your shapefile is 3D or not:

C:\DATA>ogrinfo tb.shp
INFO: Open of `tb.shp'
      using driver `ESRI Shapefile' successful.
1: tb (3D Line String)

As for the attribute issue, I have added a new field of DOUBLE type to your shapefile without a problem, and set a random value which was correctly inserted. When do you see the value switch to zero? Does it happen when you hit [enter] or when you exit editing mode?

Now it's my turn to say wow - I've never heard the term "inexpugnable" before - mssrs Google and Wikipedia tell me it means 'impregnable', so I see where you are coming from...

I've attached one of the shapefiles in question; ff you can have a look at it that would be great, but no problem if not.  I'm afraid it is a mess, but I didn't collect it!

Regards

Cain

Wow,

If we were archaeologists we would say it's an "inexpugnable" shapefile.

If  nobody tells you the solution in a reasonable time, you can send one of those shapefiles to the list so we can test it ourselves.

Dear Juan Lucas - I can get lines I have digitised to split, or imported from other sources, just not the shapefile I have imported from the GPS...

Dear Anna - Thanks for that.  I have already been using your manual, and very useful it is too. 

And I can't update ANY attribute tables manually; is there a freetext option when adding fields to tables, or are they all numeric?

Thanks again,

Cain

A basic tutorial on splitting geometries (and vector data editing in gvSIG) can be found within our Open Source Survey & GIS Manual: http://library.thehumanjourney.net/367/

All best,

Anna

Hello,
the split geometry tool is enabled when a geometry is selected. Use this tool to select the geometry you wish to split:

http://forge.osor.eu/plugins/scmsvn/viewcvs.php/*checkout*/trunk/extensions/extIconThemeBase/images/22x22/edition-geometry-select.png?root=gvsig-desktop&rev=15922

As for the input issue, I have no idea. Try to input simple values, perhaps you are trying to input too many digits?

Regards,
Juan Lucas Domínguez Rubio

Hi,

Can anyone help? I am a new user, learning on the job, and I'm having a few problems.

I have new layers from shapefiles exported from a GPS; I can open the data, manipulate it (move, copy etc) but cannot do anything more fundamental to it.

For instance, I want to split polylines but the Split Geometries tool remains permanently greyed out. Also, if I try to add information to the new fields I have added to the attributes table, when I [return] after inputting, it reverts to '0'.

I have probably missed something incredibly basic, so please, any suggestions (apart from 'have you made the layer editable'!) are very welcome!

Thanks in advance
