Quick Guide to ArcInfo Data and ArcCatolog

** featuring excerpts from the ArcInfo Help files **

ArcInfo uses a variety of data types to model geographic features:

Spatial Data Concepts in ArcInfo

Work in ArcInfo must be done in a "Workspace":

Users must have read and write access to the workspace for all the ArcInfo commands to work properly -- pathnames can be used to access data in other workspaces, but it is easiest for a user of command-line ArcInfo to have all the data in the same workspace.

What is an ArcInfo Workspace?

Looked at with a file manager, a workspace is a directory which contains a folder called "info" which organizes the information in the directory for ArcInfo:


Workspace uses

Pathnames

Coverages are the main type of data which are used in ArcInfo:

Coverages should be copied only using ArcInfo -- not the Windows file manager.

Coverages are a single geographic datasets stored in multiple files and folders.

ArcCatalog:

Easiest way to examine and copy GIS datasets in ArcInfo

Necessary to refresh often to see if actions actually happened

Has three different ways of looking at data: file manager; graphic/table preview; metadata

file manager view:


view data folder and dataset type
("contents" tab):

 

view dataset propeties: dataset size, feature details
(right-click data and "properties"):

 

view dataset propeties: spatial reference
(right-click data and "properties"):

rename, copy, move, and delete datasets (right-click dataset name):

export datasets (right-click dataset name):

converts between datatypes: coverages, shapefiles, geodatabases

preview dataset graphic
("preview" tab):

 

 

examine metadata
