  2. Objectives • GIS software • GIS software types • GIS software tasks • Introduction to ArcGIS

  3. GIS Maps + Information = GIS A GISis a collection of computer hardware, software, and geographic data for digitally capturing, managing, analyzing, and displaying all forms of geographically referenced information.

  4. Reality GIS Layers Buildings School Districts Streets Zip Codes Cities Counties GIS integrates all the layers…to create digital reality. • A geographic feature is any real-world object on a map, such as a single building. • A layer is the visual representation of a set of geographic features. Layers must contain spatial data. • Spatial data indicates the geographic location and shape of the feature. • In the example, buildings, school districts, streets, zip codes, cities, and counties are layers that are combined, or “layered,” using GIS to create reality.

  5. GIS software • GIS software refers to a geographic information system application, which is software used to create, manage, analyze and display geospatial data on digital maps.

  6. Types of GIS software • Desktop GIS • used to create, edit, manage, analyze and display geographic data. They are sometimes classified into three functionality categories: • GIS Editor, GIS Analyst and GIS Viewer. • Spatial database management systems (Spatial DBMS) • used to store the data, but often also provide analysis and data manipulation functionality.

  7. Types of GIS software • Web Map Servers • used to distribute maps over the Internet • Server GIS • provide basically the same functionality as desktop GIS but allow to access this functionality via networks.

  8. Tasks accomplished with GIS software Typical tasks carried out with GIS are[: • viewing / exploring data • creating data (the dataset is extended) • editing data (the dataset is modified) • storing • conflation (integrating datasets from different sources) • querying (resulting in a selection from the dataset) • analyzing (resulting in a new dataset, with new information obtained from the original dataset) • create maps

  9. Introduction to ArcGIS

  10. Introduction to ArcGIS • The Environmental Systems Research Institute, ESRI, is largest provider of GIS software today. • ArcGIS 9.2 is the latest mapping software available from ESRI. • ArcGIS is made up of a set of tools which includes the following three products: • ArcMap • ArcCatalog • ArcToolbox.

  11. 1. Arc Map View and edit data Analyze data (Geoprocessing) Create maps

  12. Arc Map ArcMap is the software used to view, edit, and analyze GIS data.

  13. 2. Arc Catalog Graphical previews View data (like Windows Explorer) Tables Metadata

  14. ArcCatalog ArcCatalog organizes and manages all GIS information such as maps, datasets, metadata, and services. ArcCatalog is very similar to the Windows Explorer application. ArcCatalogallows the user to search and browse for, and manage geographic data.

  15. 3. Arc Toolbox Map Projections Tools for commonly used tasks

  16. ArcToolbox ArcToolbox includes an assortment of tools necessary for analyzing, converting, and managing GIS data.
