Introduction to GIS and Arc GIS Overview What

Introduction to GIS and Arc. GIS • Overview • What is GIS • What is Arc. GIS • Arc. GIS Interface 1

What is GIS and how does GIS work? Combination of coordinate data and tabular data each feature has a record 2

GIS – an integration of five basic components software methods hardware data people 3

What are GIS Functions ►capture, ►store, ►query, ►analyze, ►display ►output 4

Capturing data 5

Storing data Vector formats Discrete representation of reality Pixels – photo images Raster formats Use square cells (grids, pixels) to model reality 6

Query ► Identifying specific features § Where is parcel No. 2945 Find Tail Tree Identifying features Locations with based on conditions DBH>18” 7

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 that contains the attributes of both ► Network: examines how linear features are connected 8

Display ►Maps ►Graphs ►Reports/Tables 9

Examples of GIS maps surface drapes & 3 -D modeling 10

Examples of GIS generated maps detailed topographic maps 11

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 E X T E N S I O N S Web Browser Arc. Objects Network Arc. GIS Server Application/Data Servers Arc. IMS Arc. SDE RDBMS 14

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 15

Arc. GIS Desktop Products Arc. Info Arc. Editor Arc. View Increased Functionality 16

All Arc. GIS products share common applications Arc. Info Arc. Editor Arc. View Arc. Catalog-window to database Arc. Map-displaying Arc. Toolbox-geographic 17 processing functions

What is unique about Arc. GIS? • GUI (Graphic User Interface) • Desktop Use • Customization & Programming • Extensions to Increase Functionality • Scalability 18

GUI • Arc. GIS uses a Graphical User Interface (GUI). • Instead of typed commands, menus, buttons, and tools are used. • Provides access to most controls, functionality, and operations • Each document type in Arc. GIS has its own GUI controls. • Beware: • The Arc. GIS GUI is complicated and many-layered. • There is no command-line control; all automation must be scripted. 19

Desktop Use • Unlike most major GIS software of the past, Arc. GIS will run on a desktop computer. • Desktop computers (PCs) are: • • cheap easy to administer common easy to use_ 20

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 • Beware: • Scripting is not easy to learn 21

The Arc. GIS Interface Arc. Map – viewing, editing, processing…. . 25

The Arc. GIS Interface Arc. Catalog – Data Management Editing Processing 26

The Arc. Map Interface • GUI • table of contents • map display • data frame • layer • scale 27

Toolbars ► demonstration of help tips 28

The Arc. Catalog Interface • GUI • catalog tree • catalog view • folders data sources 29

The Arc. Catalog Interface • contents mode 30

The Arc. Catalog Interface • Preview geography mode 31

The Arc. Catalog Interface • preview table mode 32

The Arc. Catalog Interface • metadata mode 33

Arc. Toolbox & Geoprocessing • Most geoprocessing tasks are accessed through Arc. Toolbox 34

Arc. Toolbox & Geoprocessing • Arc. Toolbox can be “docked” in Arc. Map or Arc. Catalog 35

Arc. Toolbox & Geoprocessing • Geoprocessing tasks can also be performed using the command line 36

Arc. Scene • Application for viewing data in 3 dimensions in “real time” 37

Arc. Globe • Application for viewing global data in 3 dimensions in “real time” 38
