ESRI: ArcGIS Software
ArcInfo
Same functions as previous software, plus contains more tools
to analyze spatial data.
ArcEditor
Same functions as ArcView, plus abilty to create, & edit
spatial data formats that ArcView cannot.
ArcView
Display map, query & analyze spatial
relationships, features & attributes
ArcGIS
ArcView, ArcEditor, & ArcInfo are
transparent to the user:
user does not need to know software type for
many GIS functions & applications
can open, display, & query data from any of
the 3 softwares.
Training focus will be
View & display data by color & symbol
Create thematic maps
Find/ locate attribute data on maps
Query and analyze data through spatial & attribute characteristics
Edit features
Creating presentation quality maps to print
ArcMap will be the application used, with some ArcCatalog &
ArcToolbox functions
ArcGIS is composed of 3 applications:
ArcMap
ArcCatalog
ArcToolBox
ArcMap:
Create maps from spatial data
Choose colors and map symbols
Analyze spatial relationships
Design map layouts for printing
ArcCatalog:
Browse spatial data (hard drive, network, or internet)
Preview spatial data & add it to ArcMap
Create & view metadata (information about the data
such as source, creation date, description, etc.)
ArcToolBox:
Tools to convert data from different formats
Change to or from shapefiles, coverages, tables,
or geodatababases
Tools to manage data
Aggregate, generalize, projections, topology, etc.
Tools to analyze data
Extract, overlay, proximity, statistics, or surface
Using ArcMap
Main Menu Toolbar
Standard Toolbar
Data Frame
Table of Contents
Map Display
Tools Toolbar
Drawing Toolbar
01_Exercise_ArcGIS
Open & display data through use of a map document (.mxd)
- map document (.mxd) window. The data layers’
characteristics contain settings such as pre-set colors, line
thickness, fill, and a specific view or scale.
Add to the Table Of Contents (TOC):
- layer A category of the data to display in the ArcMap display
window as well as listed in the table of contents; Layers can be many
formats- shapefiles, coverages, geodatabase features, raster, etc.
- data frame A collection of data layers that displays in the
display view window. Multiple data frames can exist in a map
document.
01_Exercise
Context menu- right click a layer in TOC to display the context
menu contains many more GIS options of the data layer
Navigate using Tools Toolbar such as pan, zoom in & out,
identify, and find.
01_Exercise
Open / Save Map Document
Layer Properties:Changing the appearance of displayed
data symbols
Open data layers from Arc GIS filetypes: shapefile, coverage
and geodatabase feature class
Type Name on Map & Print the map window
