Outline

  • How ArcView is organized?

  • What ArcView does?

  • Data


Project

How organized?

Project

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


Documents

How organized?

Documents

  • 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


Views

How organized?

Views

View Document

(View Window)

With One Theme

Tables

How organized?

Tables

(Table Window)


Charts

Layouts

How organized?

Documents1

How organized?

Documents

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

  • They are dynamically linked


Project files apr

How organized?

Project files “.apr”

  • 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. doesn’t save the actual data).


Arcview functionalities

What it does?

ArcView functionalities

  • 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


What it does?

View

  • 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


Table

What it does?

Table

  • displaying tables

  • selecting records by mouse /queries

  • editing tables

  • summarizing attributes of selected records

  • getting a statistics of selected records

  • Joining/linking tables


Chart

What it does?

Chart

  • creating a chart

  • modifying a chart element

  • identifying features/records on the chart


Layout

What it does?

Layout

  • adding a frame

  • manipulating a frame

  • adding a text

  • drawing graphics

  • exporting a layout to a image file


Scripts

What it does?

Scripts

  • compiling/running scripts

  • debugging scripts


Geographic data

Data

Geographic Data

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


Geographic data1

Geographic Data

Spatial Data

Descriptive

Data (Tabular data)

Feature data

Image data

(raster)

Data

Geographic Data


Spatial data

Data

Spatial 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 )


Feature data

Data

Feature 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


Image data

Data

Image 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


Tabular data

Data

Tabular 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.
