Outline How ArcView is organized?

What ArcView does?

Data

Project

How organized?

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

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?

Table of Content

View Document

(View Window)

With One Theme

TablesHow organized?

Table Document

(Table Window)

Chart Document

(Chart Window)

ChartsHow organized? “Proj5” Project With One Chart Document

Layout Document

(Layout Window)

LayoutsHow 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

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).

How organized?

ArcView functionalities ArcView divides functionalities into the core pr

ogram 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 dens

ity map, chart map) measuring distance/area analyzing spatial relationships geocoding

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

What it does?

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

What it does?

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

What it does?

Scripts compiling/running scripts debugging scripts

What it does?

Geographic Data Geographic data stores the

geometric location of particular features, along with attribute information describing what these features represent

Data

Geographic Data

Geographic Data

Spatial Data Descriptive Data (Tabular data)

Feature data(vector)

Image data(raster)

Data

Spatial data Georeferenced to known locations on the Eart

h'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 )

Data

Feature data Coordinate-based representation of map featur

es (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

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

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.
