[GRASSLIST:6151] v.out.mif - export to MapInfo MIF?

GRASS GRASS user
1

I am considering using GRASS (Mac OS X 10.2.4) alongside MapInfo for Power Mac but I am not clear as to whether the GRASS export command for MapInfo MIF, v.out.mif, actually works in 5.0.0 or not.

It is mentioned in some, but not all, command listings and documentation and it is not included among the export formats for vector data in chapter 6 of Neteler and Mitasova's book. It is listed in the command summary in appendix A of this book but MIF does not appear in the supported vector data format listing in appendix B. (The latter appendix doesn't even list MapInfo MIF as a supported import format, despite the fact that importing such files - lines only? - is described in chapter 6.)

Can somebody clear up this confusion please? I would also be grateful for any information about limitations or problems when importing from or exporting to MIF.

Thanks in advance.

I am unsure how to import DEM's into Grass.

I have been trying to use DEM's from Data Depot for US topomap areas. I am
trying to use r.in.gdal which (in man pages) says it can import USGS ascii
DEM's or SDTS format. When I try either of these it get an "Unrecognized
format" error. What the heck?

I know that I have somehow gotten a DEM into Grass in the past but don't
remember how.

Can anyone give me a clue?

thanks to whoever

It depends upon the format.

As well as the formats which GDAL supports, raw binary DEMs (e.g.
GTOPO30) can be imported with r.in.bin.

If you have no idea regarding the format, posting more details (e.g.
file names or the URL) might result in someone recognising it.

I have run gdalinfo for the dem I am trying to import. gdalinfo reports
that it is "unable to load PROJ.4 library (libproj.so), creation of
OGRCoordinate transformation failed."

I don't know where libproj.so is susposed to be or when it would have been
installed. After updating my search database (updatedb) I cannot find
libproj.so.

Anybody know anything about libproj.so and why gdal wants it?

Hopefully,
John Doucette

libproj.so comes from Proj.4, a free geographic reprojection library. You can
obtain it from http://www.remotesensing.org/proj/ .
Why GDAL needs it just to give you info on your datafile I don't know. I would
think GDAL just and only loads this lib when reprojection is needed. It is
not directly linked to it. So you will not have to recompile GDAL after
installing Proj. Just running ldconfig should do.
However, if you can compile the install of proj is easy, and it will probably
solve the error...

John,

The gdalinfo program requires PROJ.4 in order to reproject file corner
coordinates and report them in lat/long. I need to fix gdalinfo so it
doesn't report this noisily, since things work fine without the extra
lat/long corner coordinates if PROJ.4 isn't found.

Best regards,
