Introduction to GIS and ArcGIS How a GIS works Introduction to ArcGIS

A GIS integrates five basic components data method s software people hardware

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 Paper maps Digital images GPS output Coordinate lists GIS

Query Identifying features based on conditions Find all trees with DBH > 35 cm Identifying specific features Where is parcel No. 2945?

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

Analysis

Display Maps Graphs Reports/Tables

Examples of GIS maps surface drapes & 3-D modeling

Examples of GIS generated maps detailed topographic maps

How a GIS works Introduction to ArcGIS

What is ArcGIS? ArcGIS Clients Application/Data Servers Components ArcGIS Desktop EXTENSIONSEXTENSIONS ArcGIS Engine ArcObjects RDBMS ArcSDE ArcGIS Server ArcIMS EXTENSIONSEXTENSIONS Network ArcReader ArcView ArcInfo ArcEditor Custom Application ArcPad Web Browser

ArcGIS Desktop Products Increased Functionality ArcView ArcInfo ArcEditor

The history of ESRI products time ArcInfo ArcView ArcGIS ArcView ArcEditor ArcInfo

All ArcGIS products share common applications ArcView ArcInfo ArcEditor ArcCatalog-window to database ArcMap-displaying ArcToolbox-geographic processing functions

What is unique about ArcGIS GIS? GUI (Graphic User Interface) Customization & Programming Extensions to Increase Functionality Scalability

GUI Beware: The ArcGIS GUI is complicated and many- layered. 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 ArcGIS 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

Scalability ArcObjects RDBMS ArcSDE ArcGIS Server ArcIMS Network ArcReader ArcView ArcInfo ArcEditor Custom Application ArcPad Web Browser ArcGIS Desktop The ArcGIS suite contains  Desktop application (we will be using this quarter)  Data server application (ArcSDE)  Application servers (ArcGIS Server)  Internet mapping servers (ArcIMS)
