ArcView Data Storage

Introduction to ArcView

Objectives

Recognize function of a “map document.mxd” file

Recognize what happens when a map document is copied or moved

Move a map document successfully with data.

Definitions

Map Document - the ‘file’ that organizes and keeps track of data and documents in ArcView

Data - a collection of related facts or numerical values

Documents - a window component of ArcView that allows viewing of data.

the data, it merely “points” to where it is stored.

Computer 1 Computer 2Any data on:

“C:” must be copied over to 2nd computer

any networked drive is okay if 2nd computer has access

Zip disk: or any other movable storage must be moved to the new computer- keeping same “drive allocation”

ArcView Map Document

ArcView Map DocumentMap document.mxd saved to floppy disk

Data stored on C: drive

and on G: network drive.

Map Document will open in different computer.

But only data on floppy or network drive will display. This computer can’t see the first computers “C:” drive.

If data on “C:” drive of first computer is copied to second computer…

Then entire Map Document can be viewed.

A Map Document.mxd does not store the data… It merely points to where it is stored!
