Dear Colleagues,
I have an ESRI shapefile with approximately 20 000 polygons in a geographic
projection (WGS84). I have used the following command to convert the
shapefile to a utm34s projection.
ogr2ogr wckznwimsextract_utm34s.shp wckznwimsextract.shp -t_srs EPSG:32734
-s_srs EPSG:4326
the coordinate transformation works perfectly however the attribute data in
the new shapefile is incorrect. In fact very little of the original data is
present, dates in the original data are now null (two different formats
2009-01-01 & 23-Mar-2008) with other text and numerical attributes also now
removed. All columns from the original data are present but none of the
original data remains.
If anyone could comment on this problem and or suggest a solution I would
greatly appreciate it.
Wesley,
I think you would need to file a ticket, and make the data available for
us to effectively address this issue. We have encountered some shapefiles
(well dbf files) with dates formatted in unconventional formats that has
defeated the date parsing in the shapefile driver. Perhaps you are running
into this. There has been some progress in GDAL "trunk".
But it is hard to provide meaningful info without seeing the problem
"up close".
Best regards,
--
