ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, GIS is more file-intensive than most other computer applications Knowledge of OS file system operation is critical Disk, directory, and file management skills  Disk space  Directory structure & nomenclature File nomenclature, file sizes, multiple-file data sets Where (file system-wise) is every file in the current project? 5 of 26 General system file management

ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, Default location for new files Set the working directory early Avoids major headache later Have no doubt about where new files will be placed TIPs:  Create a new directory for each project  Set working directory to the new directory New data sets can be easily archived 6 of 26 Setting the working directory

ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, Geoprocessing environment: default output directory, etc. 7 of 26 Setting the working directory

ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, Be careful about renaming & copying files Every file of a multiple-file data source must be renamed/copied Files that are renamed/copied will not be “found” in map documents Files to be copied/renamed cannot be in use in current project Data sources are frequently composed of multiple individual files  Shapefiles are composed of at least 3 separate files  Image data sources are composed of at least 1 file, at most 4 8 of 26 Renaming & copying

ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, Use OS find files functionality to identify all files in multiple-file data sources 9 of 26 Renaming & copying

ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, of 26 Renaming - Use ArcCatalog ArcCatalog renames all files with one operation

ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, of 26 Copying - Use ArcCatalog! ArcCatalog copies all files with one operation

ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, ArcCatalog functionality applies to any supported data sets Other files can be copied/moved/renamed using OS file management  images  text files  dBase files (that are not theme tables)  CAD files 12 of 26 Renaming & copying

ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, Create new “backup” directories, copy files Write to stable media (tape, CD, DVD, etc.) Use archiving tool, e.g. PKZip, WinZip, tar  create archive files  copy to “safe” directories  write to stable media 13 of 26 Managing non-ArcInfo data sets: Archiving

ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, ArcCatalog will rename, copy, and move  Coverages  grid data sources  TIN data sources Possible to convert any vector data format to and manage as shapefile or geodatabase  Possible loss of informational content 16 of 26 Managing ArcInfo data sets: Copying & Renaming

ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, Coverage, grid, & TIN themes  Use standard ArcCatalog rename & copy  Archive files as you would any other files  create archive files  copy to “safe” directories  write to stable media  NEVER attempt to manage ArcInfo (coverage, grid, or TIN) source files with the OS; you will corrupt your data 17 of 26 Managing ArcInfo data sets: Archiving

ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, ArcInfo File Structure some of the files in the info directory are associated with files in the geodataset directory 18 of 26 Dealing with ArcInfo coverages

ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, ArcInfo data sets are somewhat problematic in ArcGIS Cannot be edited without ArcInfo run level Convert & manage as shapefile  Loss of informational content if polymorphic data set Import to whole new directory/folder  copy & archive entire directory Do not alter Info directories/folders  you will corrupt data 19 of 26 Dealing with ArcInfo coverages

ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, ArcGIS map document files do not “contain” copies of data sets ArcGIS map documents contain instructions that include pointers to data location File locations are “hard coded” into project files 21 of 26 Copying & Moving Map (.mxd) Documents

ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, Copying & moving map documents does NOT copy or move data sets Data sets must be either:  Moved  Identical file structure  Copied  Identical file structure  Specified  Restructure your.mxd map document 23 of 26 Copying & Moving Map (.mxd) Documents

ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, Map documents may specify absolute or relative path names to data sources 24 of 26 Copying & Moving Map (.mxd) Documents

ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, Map documents may specify absolute or relative path names to data sources  With relative path names, if data sets are in the same folder as the map document, the entire folder can be moved, copied, or renamed.  With absolute path names, file structures must be recreated identically if map documents and data sets are to be copied to a different computer. 25 of 26 Copying & Moving Map (.mxd) Documents
