Ok bu sooner or later, users may have to manage data in this "projection" system, and they might be puzzled (angry) to see it does not work despite a proper location Join them; it only takes a minute: Sign up Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the Furthermore, if the ~/.Xsession sources the bash startup scripts, the settings aren't limited to interactive shells, but also work for e.g.

EPSG 3416 ETRS89 / Austria Lambert can you comment on if the results are as you expect? These can be updated if necessary to support future revisions of the EPSG database. If I open a "old" mapset (don't remember exactly when it was created), that was created with EPSG 40000, g.region -p will return as expected projection: 99 (Transverse Mercator) zone: 0 The projection information will be read from this file.

When adding to SVN, currently these files are still in lib/gis/. Hamish comment:6 follow-up: ↓ 7 Changed 3 years ago by hamish besides the one on line 1500, maybe also needed in wizard.py line 901, 1346? These are: PROJ_INFO contains the location's projection information PROJ_UNITS contains the location's map units definition DEFAULT_WIND the default region (WINDow file). This approach is sufficient for most cases, but it has two drawbacks: spatial outputs are returned without coordinate system information; GRASS commands that require a coordinate system (e.g.

Can Communism become a stable economic strategy? See the Batch jobs section of the GRASS shell-help wiki page for details. PyWPS creates two mapsets inside this location, the PERMANENT mapset and a working mapset also identified by the PID, where all GRASS commands issued from within the process are executed. We recommend to use the ERDAS/Img format and not to use the ESRI style of WKT: # example for 30x30 pixel resolution (enforce with -tr to avoid odd values) gdalwarp -of

The -d flag will report a human-readable summary of this. The PROJ4 functions are used through wrapper functions in a GRASS environment. The old text based g.setproj location creation tool doesn't have this problem since it creates the PROJ_INFO from terms directly. If compiled without OGR present, the functionality is limited to: Reporting the projection information for the current location, either in conventional GRASS (-p flag) or PROJ.4 (-j flag) format Changing the

Optionally you can put a VAR file in there too to define the default database driver to use.

ps- please try to only use pseudo-mercator if data import/export demands it, it is the cause of much pain. :-) I keep it in mind from then... Restore what ? right, g.proj -jf returns +proj=merc +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +no_defs +a=6378137 +rf=298.257223563 +towgs84=0.000,0.000,0.000 +to_meter=1 while proj.4 epsg file says <3857> +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m [email protected] test 2: no datum setup by terms: proj -> ll, ellipsoid only -> sphere -> error.

comment:10 Changed 3 years ago by hamish (r56160 fixed by r56161, the "test 2: no datum" case is hopefully now fixed too in devbr6 and trunk) datum transform selection by epsg If the user needs a process able to operate on different coordinate systems and keep this information in resulting datasets or if it needs to run GRASS commands that require a Added by Giovanni Manghi over 5 years ago. The most reasonable conclusion, however, was to not use this system at all because of it's weird nature.

the PROJ.4 function called by 'g.proj -c' sees there is missing datum transform opts and decides that it should add one. If the file is not georeferenced or cannot be read, XY (unprojected) will be used. comment:25 in reply to: ↑ 24 ; follow-up: ↓ 26 Changed 7 weeks ago by mlennert Replying to neteler: Can you restore it locally from the last rev and test?

At this stage, I'm not sure what the solution would be.
