CFR 250/590 Introduction to GIS, Autumn 1999 Data & Project Management © Phil Hurvitz, proj_mgmt.ppt 3 Managing non-ARC/INFO data sets: General system file management 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 nomenclature File nomenclature, file sizes, multiple-file data sets Where (file system-wise) is every file in the current project?_

CFR 250/590 Introduction to GIS, Autumn 1999 Data & Project Management © Phil Hurvitz, proj_mgmt.ppt 4 Managing non-ARC/INFO data sets: Setting the working directory Set the working directory early Avoid major headache later Have no doubt about where new files will be placed TIP: Create a new directory for each project Set working directory to the new directory Always use the Startup Project New data sets can be easily archived _

CFR 250/590 Introduction to GIS, Autumn 1999 Data & Project Management © Phil Hurvitz, proj_mgmt.ppt 5 Managing non-ARC/INFO data sets: Renaming & copying 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 projects 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. _

CFR 250/590 Introduction to GIS, Autumn 1999 Data & Project Management © Phil Hurvitz, proj_mgmt.ppt 14 Managing ARC/INFO data sets: Copying & Renaming ArcView will rename & copy grid data sources TIN data sources Possible to convert to and manage as shapefile Loss of informational content _

CFR 250/590 Introduction to GIS, Autumn 1999 Data & Project Management © Phil Hurvitz, proj_mgmt.ppt 15 Managing ARC/INFO data sets: Archiving Standard rename & copy Archive files as you would any other files create archive files copy to “safe” directories write to stable media _ Grid & TIN themes

CFR 250/590 Introduction to GIS, Autumn 1999 Data & Project Management © Phil Hurvitz, proj_mgmt.ppt 16 Managing ARC/INFO data sets: Dealing with ARC/INFO coverages Problematic data sets in ArcView ArcView cannot “manage” ARC/INFO coverages Coverages cannot be copied, moved, or renamed Convert to & manage as shapefile Loss of informational content if polymorphic data set Import to new directory; copy & archive entire directory Never use OS file management to manipulate coverage, grid, or TIN directories Do not alter info directories; you will corrupt data _

CFR 250/590 Introduction to GIS, Autumn 1999 Data & Project Management © Phil Hurvitz, proj_mgmt.ppt 17 Copying and moving projects ArcView project files only contain pointers to data location File locations are “hard coded” into project files Copying & moving projects does not copy or move data sets Data sets must be moved, copied, or specified Data structures must be completely recreated, or Projects that are copied or moved must be altered for new file locations _
