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?

NSDI sets standards!!! SDTS: Spatial Data Transfer System Most Federal agencies produce data in this format. ArcInfo supports this standard: SDTSIMPORT Several processes must be run before you can run : SDTSIMPORT winzip Tar SDTSIMPORT SDTS2COV.amlSDTS2ARC.aml

Common File Formats: DXF SDTS USGS DEM USGS DLG ArcInfo EXPORT ArcInfo IMPORT ArcView SHAPE files Standard Data Transfer System Digital Elevation Model Digital Line graph AutoCAD engineering format.shp.shx.dbf TIGER/LINE Topologically Integrated Geographic Encoding and Referencing system

TIGER/LINE data TIGER/Line 1999 (Bureau of the Census) Topologically Topologically Integrated Integrated Geographic Encoding Encoding and Referencing Referencing system The TIGER/Line files are a digital database of geographic features, such as: roads, railroads, rivers, lakes, political boundaries, census statistical boundaries, etc.

LAB # 1 The purpose of this lab is to develop your skills in file conversion. In GIS there are data stored in many different types of format. In this lab you will be asked to convert 3 different types of data to an Arc/Info format. All the files are located at: ftp://ftp.nbmg.unr.edu/NBMG/gary/GIS_409/ assign1_g.dem SDS _ txt.gz (sdts data) TGR32031.zip (TIGER98 data) G zip.exetar.exesdts2arc.exeWINZIP assign1_topo.e00 NV_BND.DXF Counties.zip Due September ?, 2003 (Thursday 5:30 p.m.)
