DDF to mapinfo converter

[Martin Rodrigue]

I download a SDTS file (DLG) and when I unzipped it, it was a DDF file. Does
someone know a freeware to convert it to mapinfo

Martin,

Sol Katz wrote the sdts2mif utility which you can get at:

ftp://ftp.blm.gov/gis/sdts/dlg/sdts2mif.exe

There are various other SDTS related utilities on the same site.

The commercial FME software also includes SDTS support now.
(disclosure: I wrote it for them on contract). I also maintain a free
library for accessing ISO8211 (the encoding underlying SDTS) if you want
to build a translator of your own.

Best regards,

I don't know this format or a freeware to translate it, but you can have
a look to a canadian company called Global Geomatics which develop tools
to access directly native formats. To my knowledge, they support over 40
formats.

Hope this help,

John

Martin, John,

MapInfo does not yet have direct import capabilities for SDTS data (.ddf),
but there are several third-party solutions.

The SDTS tutorial and translator documents are at
http://mcmcweb.er.usgs.gov/sdts/warning.html
and the translator document is directly at
ftp://sdts.er.usgs.gov/pub/sdts/articles/ascii/translators.txt
with a section on how to convert SDTS DLG data to MapInfo format.

For SDTS vector data, including SDTS DLG data, there are a number of
translators, including
GeoMorph
http://www.active-ware.com/geo/index.html
GIS Tools
http://www.gistools.com/
Safe FME
http://www.safe.com/
and likely Global Geomatics in the near future as John noted.

Vertical Mapper software
http://www.northwoodgeo.com/
adds SDTS raster (DEM) capabilities to MapInfo.

Additional SDTS information is on the web at
http://mcmcweb.er.usgs.gov/sdts/
and questions can be sent to the SDTS experts at
sd...@usgs.gov

Lots of great MapInfo information from Bill Thoen is at
http://www.ctmap.com/gisnet/
and now at
http://www.directionsmag.com/mapinfo-l/

HTH,
Charley
