These data files are commonly referred to as coverages and grids. When viewed from the command line or Windows Explorer, each coverage or grid appears as a subdirectory or folder containing numerous files. The data storage structure of these files is complex and makes use of relational database principals. Simply copying a coverage or grid from the CD to a users computer will likely result in a corrupted version on the users machine. This is because not all of the required files will be transferred and the relational links to necessary portions of the data will be lost. A user may transfer the entire Coverages and or Grids directory to their hard drive or other suitably large storage devise without corrupting the data files contained in the directory. The procedure is different if a user only wants to transfer selected coverages or grids to their computer. Without GIS software, individual coverages or grids must be copied to the user's computer using special export files that allow the dataset to be transferred without corruption. The (zipped) export files for each dataset in the Browser are provided in the Exports directory, and may be copied from the CD to another storage devise using the copy command from the command line or any of the methods available in Windows Explorer. These files can also be downloaded to a location of the user's choice by clicking on the 'Download' button on each data page in the browser. Coverages - all coverages are provided as ArcInfo Export (*.e00) files in the Exports directory, and have been compressed using ZIP or GZIP. Once transferred to your computer, the files need to be uncompressed using Winzipor similar product. A copy of the current version of WinZip is included in the WinZip directory on this CD. Installation of the WinZip software is accomplished by double clicking the winzip70.exe file from Windows Explorer. WINZIP IS NOT FREEWARE. REGISTRATION OF THE PRODUCT IS THE USERS RESPONSIBILITY IF THE APPLICATION IS USED BEYOND THE EVALUATION PERIOD. The Import71.exe file located in the ArcExplorer directory will install the software necessary to convert the uncompressed export (.e00) files into coverages. To install, double click the import71.exe file in the Windows Explorer. Once installed, the Import71 utility prompts the user for the location of the export file to be imported and the location of the directory where the imported coverage should be placed. Numerous export files can be imported into the same directory. Once imported, the individual coverages should only be modified or relocated using GIS software. Grids - the creation of Export (.e00) files for grids is less efficient than simply zipping workspaces containing individual grids. As a result, the grids on this browser are provided as compressed *.zip files for transfer/download. Once unzipped, the grids are ready for use, and do not need to be imported using the Import71 utility. Please do not, however, copy the grids out of the workspace/directory they come in using anything other than GIS software. A workspace is the directory containing the 'info' directory, and the dataset directory. Shapefiles - a shapefile is actually a group of files with the same name, but different file types (e.g. *.shp, *.shx, *.dbf, etc.). For convenience, these files have been zipped/compressed into one file for transfer/download that can be found in the 'Exports' directory. They may also be copied directly from the 'Shapefiles' directory using Windows Explorer, provided that you are careful to copy all of the files with the same base name.
