hi again! here's another primer in how to convert usgs data to mapinfo found on the ftp site. greg [EMAIL PROTECTED] SDTS TO MapInfo MIF 1. Go to: http://edcwww.cr.usgs.gov/doc/edchome/ndcdb/ndcdb.html 2. Pick up SDTS data (For examples below we used: 1:2,000,000 Missouri boundaries(Mo.bound.sdts.tar.gz), 1:100,000 Rolla West boundaries (RY1.bdy.sdts.tar.gz) and 1:24,000 Salem boundaries (D3609142.bd0s.1.sdts.tar)). 3. Go to: ftp://sdts.er.usgs.gov/pub/sdts/software/tools 4. Pick up: gunzip.exe and tar.exe (Place in directory with SDTS files. 5. Decompress and untar data as follows: a) gunzip <SDTS file name>.gz (RY1_bd~1.gz or whatever Windows95 called it) b) tar xvf <SDTS file name> (RY1_bd~1) 6. This will give you a bunch of .ddf files 7. Go to: ftp://ftp.blm.gov/pub/gis/sdts 8. Pick up: SDTS2MIF.EXE (Place in directory with .ddf files) 9. Go to a DOS prompt and change to the your file directory 10. For this step, different procedures are required depending on the data scale involved: FOR 100K MAPS: Type: sdts2mif BD01 bd100k1 01 sdts2mif BD01 bd100k2 02 sdts2mif BD01 bd100k3 03 sdts2mif BD01 bd100k4 04 where: sdts2mif = the executable BD01 = first 4 characters in SDTS file name 01-04 = tile numbers bd100k? = your name for the mif file FOR 7.5' MAPS: Type: sdts2mif BD01 bd24k 01 where: sdts2mif = the executable BD01 = first 4 characters of SDTS file name 01 = numbers in the 7 and 8 positions in the file name bd24k = your name for dxf file FOR 1:2,000,000 MAPS: Type: sdts2mif MOBD bd2m 01 where: sdts2mif = the executable MOBD = first 4 characters of the SDTS file name 01 = numbers in the 7 and 8 positions in the file name bd2m = your name for the dxf file 11. Start MapInfo 12. Click Table/Import 13. Change file type to .mif 14. Save file with your name 15. Choose Open file and highlight your file 16. Choose Open This creates an empty .mid file and while there is an attr2mid.exe translator I have not yet figured out how to use the 2 translators together. If bringing in the 100K you will need to import all 4 tiles. Conclusions We hope this information helps you make use of SDTS data.
