ArcGIS: Introduction to ArcView 9

1. ArcGIS: Introduction to ArcView 9 Shelly McCoy

2. Workshop Topics What is GIS? Data used in ArcGIS Performing basic operations in ArcGIS Looking at table data Changing Symbology Making queries Making a layout Campus Resources

3. The amount of information you can get from a paper map is limited to what is shown�

4. A geographic information system (GIS) is a computer-based tool for mapping AND analyzing things that exist and events that happen on Earth.

5. These abilities distinguish GIS from other information systems and make it valuable to a wide range of public and private enterprises for explaining events, predicting outcomes, and planning strategies.

6. With digital mapping technology, maps can be used to help� A water department find the valves to isolate a ruptured water main An engineering department monitor the conditions of roads and bridges and produces planning maps for natural disasters A business evaluate locations for new retail outlets by considerations concentrations of nearby customers A transit department produce maps of bicycle paths for commuters A hydrologist monitor water quality to protect public health A biologist study the impact of construction plans on a watershed.

7. Major Companies Using GIS Federal Agencies Chase Manhattan Sears Roebuck & Co. Domino�s Pizza Realtor.com MBNA Metropolitan Life Police and Fire Depts Ace Hardware Gold�s Gym US Postal Service Minolta Corp. Conectiv UPS AAA State/Local Gov�t

8. Simply said: Geographic � maps Information � data System � digital A GIS links information to geographic location (connects the what to the where), allowing you to seek patterns and relationships that may not otherwise be apparent.

9. What GIS Can Do for You Explore �see and interpret spatial relationships Analyze �create new information and find hidden patterns Present results: ready your maps for output

10. GIS uses more than just geographic data: Start with geographic data, such as a county Attribute data that has a relationship to this county can include: mean monthly humidity average rainfall average acres of crops population and demographics zip codes, census tracts, etc.

11. So, each layer contains 2 kinds of information: Spatial information �location and shape of the geographic features Attribute information �other characteristics of the features

12. Geographic Data Think of your local neighborhood and all of the things along your street.Think of your local neighborhood and all of the things along your street.

13. Descriptive Data There are also many descriptive pieces of information about all the things in your neighborhood.There are also many descriptive pieces of information about all the things in your neighborhood.

14. Geographic Information Associated with every thing is a story, or this descriptive information.Associated with every thing is a story, or this descriptive information.

15. Example from the most common GIS software application called: ArcView. Showing tax parcels and where water lines are located. Not only where they are located but more information such as depths of water lines, etc. All of the layers are located on the left-side in the table of contents.Example from the most common GIS software application called: ArcView.

16. Part of the new wave of GIS software uses is making 3D map images. It would not only show where this house and car is, but how many people live there, what kind of car it is, etc.Part of the new wave of GIS software uses is making 3D map images.

17. The current trend in GIS is on web-based mapping. This capability can allow users to view an already created map or create maps, based on their own specifications, on their personal computers. Web-based mapping is expected to widely expand the use of GIS in the workplace, in schools, and in homes. Sometimes a nice geographic map is enough. For example�

19. D a t a Possibly the most important component of a GIS is the data. A GIS will integrate spatial data with other data resources A GIS provides the path to the data, which are shown in the software as layers

20. A bit about layers Layers can be features or surfaces Maps and layers are important ways of organizing and displaying data in ArcGIS. Layers are drawn on the map in a particular order.Maps and layers are important ways of organizing and displaying data in ArcGIS. Layers are drawn on the map in a particular order.

21. Where do you get this data? GIS CD-ROMs/DVD-ROMs Morris Library, RDMS, or commercially Internet Colleagues YOU provide it!

22. Data Formats in ArcGIS Shapefile Coverage Geodatabase ArcIMS Feature Services ArcIMS Map Services Geography Network Text files (.TXT) OLE DB tables PMF Rasters ESRI� GRID ERDAS Imagine (.IMG) Windows Bitmap (.BMP) ER Mapper (.ERS) Graphic Interchange Format, GIF (.GIF) ADRG Image (.IMG) JPEG File Interchange Format, JIFF (.JPG) Portable Network Graphics (.PNG) LizardTech MrSID (.SID) Tagged Image File Format, TIFF (.TIF)

23. ArcView 9 has a two part interface:  ArcCatalog � for navigating spatial data ArcMap � for creating, viewing, querying, editing, composing, and publishing maps ArcCatalog is similar to the Windows �explorer�, or the �My Computer� icon on your windows desktop. It is a tool for navigating through your GIS datasets. Preview data by clicking and expanding the C: drive on the left side and clicking on one of those files. View or edit Metadata. ArcToolbox contains analysis, conversion, and data management tools �most of which use wizards to walk you through the steps. If you click once on one of the topics, it will give you a description of what it covers below.. Arc Map is the interface where you will spend most of your time as this is where GIS data layers are drawn and listed in the Table of Contents (on the left side where you see �Layers�). The map display can be viewed in two ways: Data View is the default view and is where most of the analysis and visualization takes place, and Layout view is where you gain access to cartographic tools to ready your map for presentation. You can tell what view you are in by going to the View menu and seeing what is selected.ArcCatalog is similar to the Windows �explorer�, or the �My Computer� icon on your windows desktop.
