What file formats (DXF, DLG, DIME, TIGER, IGDF, etc)
can GRASS read and write?

Thanks in advance.

I'm not a great importer/exporter of maps, but
a quick check of [r|s|v].[in|out].* reveals:

r.in.ascii r.in.ll r.in.poly r.in.sunrast r.in.utm r.out.ascii
r.out.tga v.in.arc v.in.dlg v.in.dxf v.in.tig.basic v.in.tig.rim
v.in.ascii v.in.dlg.scs v.in.poly v.in.tig.lndmk v.in.transects
v.out.arc v.out.ascii v.out.dlg v.out.dxf v.out.moss s.in.ascii
s.out.ascii

So, for input, it appears to support ascii, arc, dxf, tiger,
dlg, and sunrast (with pbmplus -> any common image format).

For output, it appears to support ascii, targa, arc, dlg, dxf,
and moss.

Disclaimer: I've never used very many of these.

Two people provided answers to my question "What file formats

Thanks for your help.

Here are their answers:

From markline(a)henson.cc.wwu.edu:

At *least* the following (there's contributed software out there that I
probably don't know about; what's listed here seems to actually work: 8)

Imagery Import:

erdas
MSS tape
SPOT tape
TM tape
generic tape

Raster Import:

ASCII
SUN screendump
USGS DEM tape
DMA DTED on USGS tape
DMA DTED tape
USGS Landuse/Landcover Composite Theme Grid (LULC CTG)

Vector Import:

ARC
ASCII (Coordinates)
ASCII (Transects)
DLG
DLG2
DXF
TIGER

Point Import:

ASCII
U.S. Census PL94-171 dBase3 CD-ROM
U.S. Census STF1A dBase3 CD-ROM

Raster Export:

ASCII

Vector Export:

ARC
ASCII
DLG
DXF
MOSS

Point Export:

ASCII

Also, you can generally convert among GRASS' own formats and between UTM
and Lat-Long.

I'll keep my eyes open for other readers/writers that I might come across.
Hope this helps.

a few thoughts:

perhaps an enterprising programmer could take this summary
and start planning r.export/r.import and v.export/v.import...
type= input= output=

maybe someone with lots of experience could write something
for grassclippings...

I don't have the need to work with a lot of different data
formats, so am admittedly ignorant of the ins/outs
('awk' usually does everything I need).
