ArcView 3'13'2

ArcView 3.1/3.2

• An Overview
• As of January 2000, ArcView 3.2 was superceded by
  ArcGIS 8.
• The term ArcView was applied to the lowest level
  tier of ArcGIS 8.
• Progressively higher tiers, all with a common
  interface, were termed ArcEditor and ArcInfo

2
Arcview Components

• projects
• all components associated with a particular
  undertaking
• comprised of views, tables, charts, layouts,
  scripts
• view
• essentially a map which you look at or view
• contains one or more themes
• themes
• layers of spatial data with similar
  characteristics (eg streets, hydrolgy, capitals)
• in ARC/INFO called coverage if vector, grid if
  raster

• tables
• rows (usually geographic locations, linked by ID
  to theme features)
• columns describe attributes (characteristics) of
  locations
• chart
• business graphics to display geographic and
  tabular data
• layout
• graphic output/screen display of views, tables,
  charts
• script
• automation feature written in Avenue which allows
  full customization

Arcview Components Projects

• Project (workspace)
• all components (documents) associated with a
  particular undertaking
• stored in file with extension .apr
• components dynamically updated change one part,
  other parts updated accordingly.
• reopens in identical form to when closed
• five types of documents available views,
  tables, charts, layouts, scripts
• each document has a set of tools for working with
  it

Project
output
Layout
database
Table
Chart
business graphics
View
geographic features (a map with one or more
themes)
scripts (provide automation, special effects,
etc)

ArcView Components Views Themes

• a view is essentially a map which you look at
  (view) on the screen (or print with layout)
• it contains one or more themes (ARCINFO
  coverages/grids) which are layers of spatial data
  with similar characteristics eg streets,
  hydrolgy, capitals
• only one view active at a time
• themes listed in ArcView Table of Contents which
  allows you to control themes to be viewed
• themes are added from View window using View
  pull down menu

Data is organized by layers, coverages or themes
(synonomous concepts), each representing a common
feature.

ArcView ComponentsTables Charts

• contains attribute (descriptive) data
• can create in ArcView or access data from other
  sources (e.g via SQL)
• references to tables are stored, not data itself
  (therefore automatic update)
• event tables contain geographic references and
  can be mapped (non-event tables can simply be
  included in layouts)
• charts can be used to display tabular data.
• 6 types area, bar, column, line, pie, scatter

Since data is stored in dBase tables and Excel
can read these, its often as easy to use Excel
(or similar) for graphing, especially for
one-off charts.

Data Types in basic Arcview (3.2) others
available via standard (free) or optional (extra
) extensions

• Vector (spatial)
• shape file ARCVIEWs native format (object
  database model)

  database model)

  for Windows apps.)
