[FWTools] FWTools Digest, Vol 71, Issue 2 - ogr2ogr convert MIF to SHP file that contains Text Object

[Jiang, David]

Hello, Richard,

Sorry, could you please explain a little bit more on how to use "Update
column" to assign text to an attribute in MapInfo for this case?

To me, seems that after I run [ogr2ogr.exe -f "ESRI Shapefile" -where
ogr_geometry='POINT' drawing_layer_#3_point.shp drawing_layer_#3.mif],
the above command generates 4 files (in the attachment). But
drawing_layer_PT.dbf doesn't keep the description. How can I update
description column when I open these files in MapInfo? There are Point
and Text objects in the MIF file. Should I use a different ogr_geometry
value for Point object?

In MapInfo Prof, there is this Universal Translator tool. When I use
Universal Translator to convert drawing_layer_#3.mif to ESRI shape, it
does generate a separate set of shape files for the text object in MIF
besides the shape files for lines, regions and points. And I can see the
description in the dbf file.

What I am trying to do is: from our application, execute DOS command
calls ogr2ogr.exe to convert MIF file to ESRI Shape. But it seems that
ogr2ogr.exe cannot handle Text type in MIF file at this point.

Thanks very much!
David

Shape files don't have text objects, so you'd need to assign the
MapInfo text to an attribute. This can easily be done in MapInfo using
the "Update column" menu option with the objectinfo(obj,3) function.

HTH,
Rich
