[gdal-dev] Projection definition issue with Mapinfo files

[Yves Jacolin]

Hello,

One of QGIS user report an issue with mapInfo file (TAB file). If you understand 
french you can see the thread here:
http://georezo.net/forum/viewtopic.php?pid=197022

I try to sum up the issue in english in this email. The process is basicly as 
follow:
1. check projection information with ogrinfo 

> DATUM["GRS_80",
>             SPHEROID["GRS 80",6378137,298.257222101],

2. update projection information file with ogr2ogr:
> ogr2ogr -f "MapInfo file" -s_srs "EPSG:2154" -t_srs "EPSG:2154" new.tab 
origin.tab

3. check projection information with ogrinfo

> DATUM["WGS_1984",
>             SPHEROID["WGS 84",6378137,298.257223563],

1 and 3 show differents projection information! If I try to change file format 
to shp, it seems that projection information are correct.

I can share tab files if needed.

Any idea? Thanks.

Y.
