  1. Data Conversion Can your data be read by me? Can my data be read by you? What software do you use? Are there any standards for data conversion?

  2. Common File Formats: DXF AutoCAD engineering format SDTS Standard Data Transfer System Digital Elevation Model USGS DEM USGS DLG Digital Line graph ArcInfo EXPORT ArcInfo IMPORT ArcView SHAPE files .shp .shx .dbf

  3. NSDI sets standards!!! SDTS: Spatial Data Transfer System All Federal agencies produce data in this format. ArcInfo supports this standard: SDTSIMPORT Several processes must be run before you can run SDTSIMPORT. Tar winzip SDTSIMPORT SDTS2COV.aml SDTS2ARC.aml

  4. AutoCAD format (DXF) Pretty straight forward BUT: If the AutoCAD file is in color and layers there may be some other files in the info directory that need to be joined. (X_code, A_code) Arc:\DXFINFO = inventories the layers in the DXF file Arc:\DXFARC = opens a dialogue to convert the layers

  5. Adding a .DXF file to ArcView

  6. Adding a .DXF file to ArcView

  7. Adding a .DXF file to ArcView

  8. USGS DEM Digital Elevation Model: Converts to a grid Is converted in both ArcInfo and ArcView DEMLATTICE or DEMGRID SDTS2ARC.aml

  22. IMPORT71 Command

  23. Converting Shape files Shape files must have at least 3 different files with the same name to make them valid. .shp file .shx file .dbf file .prj file

  31. Exercise 2 All the files are located at _instruct/ftp_files ftp the four files into your workspace and convert the first 4 of them to an Arc/Info format. assign1_g.dem assign1_topo.e00 counties.zip NV_100k.DXF Assign_g405_605.tif (Save this file for a February digitizing assignment.) Put the different files in an ArcView layout and print the results of your file conversions. Remember to have your name, date, and the exercise number in the layout.
