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

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
