Introduction to GIS and Arc. GIS How a GIS works Introduction to Arc. GIS
A GIS integrates five basic components software methods hardware data people
Data
Types of datasets Vector formats (“feature classes”) Points Lines (”arcs”) Polygons
Types of datasets Raster formats Matrices of square cells (grids, pixels)
Types of datasets Attribute tables: tables of data describing spatial features
Methods
Basic GIS Functions Capture Store Query Analyze Display Output
Capturing data Digital images Paper maps GIS GPS output Coordinate lists
Query Identifying specific features Where is parcel No. 2945? Identifying features based on conditions Find all trees with DBH > 35 cm
Analysis Proximity : which roads are within a 100 ft from a stream Overlay: combines the features of two or more layers to create a new layer (intersections, unions…) Network: examines how linear features are connected

How a GIS works Introduction to Arc. GIS
What is Arc. GIS? Arc. GIS Clients Arc. Reader E X T E N S I O N S Arc. GIS Desktop Arc. GIS Engine Arc. Info Custom Application Arc. Editor Arc. View Components Arc. Pad Arc. Objects Network Arc. GIS Server Application/Data Servers Arc. IMS Arc. SDE RDBMS E X T E N S I O N S Web Browser
Arc. GIS Desktop Products Arc. Info Arc. Editor Arc. View Increased Functionality
The history of ESRI products Arc. Info Arc. View Arc. GIS Arc. View time Arc. Info Arc. Editor
All Arc. GIS products share common applications Arc. Info Arc. Editor Arc. View Arc. Catalog-window to database Arc. Map-displaying Arc. Toolbox-geographic processing functions
What is unique about Arc. GIS? • GUI (Graphic User Interface) • Customization • Extensions • Scalability & Programming to Increase Functionality
GUI Beware: The Arc. GIS GUI is complicated and manylayered. There is no command-line control; all automation must be scripted.
Customization & Programming • Many functions are not available from the GUI • Custom functions and operations can be created with various programming languages • Repetitive tasks can be automated • New functions and operations can be added to the GUI menus, buttons, and tools • Entire new applications can be developed • But: Scripting is not easy to learn
Extensions -> Increase Functionality § Functionality not included in the core Arc. GIS product can increase productivity § Some extensions are built-in, but just need to be enabled § Other extensions are available for free (web); some are available for sale § We will be using several extensions during the course
Arc. GIS Desktop Scalability Arc. Info Custom Application Arc. Editor Arc. Reader Arc. View Arc. Pad Web Browser Arc. Objects Network Arc. GIS Server The Arc. GIS suite contains Arc. IMS Arc. SDE RDBMS §Desktop application (we will be using this quarter) §Data server application (Arc. SDE) §Application servers (Arc. GIS Server) §Internet mapping servers (Arc. IMS)
