Outline

• How ArcView is organized?
• What ArcView does?
• Data

3
Project
How organized?

• One project contains five types of components
  (called documents) Views, Tables, Charts,
  Layouts, and Scripts

4
Documents
How organized?

• work with a theme in Views
• manage a table in Tables
• create charts from a theme or a table in Charts
• create a high-quality map by putting together
  graphic elements in Layouts
• customize in Scripts

5
Views
How organized?
View Document (View Window) With One Theme
Table of Content
6
Tables
How organized?
Table Document (Table Window)
7
Charts
How organized?
Proj5 Project With One Chart Document
Chart Document (Chart Window)
8
Layouts
How organized?
Layout Document (Layout Window)
9
Documents
How organized?

• Each document displays data differently each has
  its own related menus, buttons, and tools
  organized in a unique interface
• They are dynamically linked

10
Project files .apr
How organized?

• allows all the works (e.g. creating maps,
  joining tables, making charts) to be saved in one
  file.
• saves only descriptive information about the
  work (i.e. doesnt save the actual data).

11
ArcView functionalities
What it does?

• ArcView divides functionalities into the core
  program and extensions.
• Core program generic capabilities
• e.g. menu/button/tool supported in the
  documents when no extensions are loaded
• Extensions additional capabilities loaded onto
  the core program
• e.g. Spatial Analyst, Network Analyst, 3D
  Analyst, Geoprocessing, Digitizer, Image Support
• We are going to learn the core program

12
View
What it does?

• displaying spatial data
• identifying features attributes
• selecting features
• thematic mapping (e.g., choropleth map, dot
  density map, chart map)
• measuring distance/area
• analyzing spatial relationships
• geocoding

13
Table
What it does?

• displaying tables
• selecting records by mouse /queries
• editing tables
• summarizing attributes of selected records
• getting a statistics of selected records
• Joining/linking tables

14
Chart
What it does?

• creating a chart
• modifying a chart element
• identifying features/records on the chart

15
Layout
What it does?

• adding a frame
• manipulating a frame
• adding a text
• drawing graphics
• exporting a layout to a image file

16
Scripts
What it does?

• compiling/running scripts
• debugging scripts

17
Geographic Data
Data

• Geographic data stores the geometric location of
  particular features, along with attribute
  information describing what these features
  represent

18
Geographic Data
Data
19
Spatial data
Data

• Georeferenced to known locations on the Earth's
  surface (i.e. employs a specific coordinate
  system, unit of measurement and map projection)
• primarily feature based (e.g. topology)
• organized thematically into different layers, or
  themes (e.g. streams, landuse, elevation, and
  buildings )

20
Feature data
Data

• Coordinate-based representation of map features
  (i.e. A point is stored as a single x, y
  coordinate, a line as a pair of x, y coordinates,
  and a polygon as a set of x, y coordinates)
• Good to represent discrete entities (e.g.
  school, event location, lake)
• Supported format in Arcview includes ArcView
  shapefiles, Arc/Info coverages, SDE layers, VPF,
  and so on

21
Image data
Data

• Cell-based representation of map features (e.g.
  satellite imagery, aerial photo)
• Good to represent continuous entities (e.g.,
  temperature, elevation, toxic level)
• Supported format in ArcView includes TIFF, JPEG,
  MrSID, Arc/Info GRID, BMP, BIL and so on

22
Tabular data
Data

• stored in a table
• ArcView supports data from database servers such
  as Oracle, Ingres, Sybase, Informix, etc, dBASE
  files, Arc/Info INFO tables, text files with
  fields separated by tabs or commas.
