  1. Introduction to GIS

  2. Introductions

  3. Introductions • Your name • Where you work • Your professional field • Have you used GIS before? • What we expect to get from this training?

  4. Course Times 9:00 AM to 11:45 PM (Morning Session) 11:45 AM to 1:00 PM (Lunch Break) 1:00 PM to 4:00 PM (Afternoon Session)

  5. Morning Session Introduction to GIS Demo & Execerise: Navigate ArcMap Attribute and Location Queries Afternoon Session Navigate ArcCatalog Compose Maps Edit and Create Data Course Schedule

  6. So … what is mapping ? • Location, Location, Location • Almost everything that happens, happens somewhere. Knowing where? and why? something happens & why do I care? is critically important! ‘Pin map’

  7. Geography is the Science of Our World Increasingly Being Seen as a Framework for • Understanding • Patterns • Relationships • Processes • Conceptualizing • Modeling • Visualizing . . . Integrating What We Know

  8. Data - Data - DataWe’ve all “got data” • Location Data -- How Many -- What Kind -- Where • Scale of Data -- Local to Global • Data Presentation -- Words, Charts, Graphs, Tables, or Maps Exploring data using GIS turns data into information into knowledge

  9. How is information normally ‘seen’? … non-spatially?

  10. How do you “see” your data? Visualization Worth a Thousand Words

  11. What is GIS? • A method to visualize, manipulate, analyze, and display spatial data • “Smart Maps” linking a database to a map

  12. A geographic information or geographical information system (GIS) is a system for creating, storing, analyzing and managing spatial data and associated attributes. Data– Accuracy and availability. Hardware – Performance of GIS functions Software – GIS and other support software People– The most component in a GIS. The people who create and manipulate the system to produce products What is GIS?

  13. GIS … a ‘spatial blend’ of location & information • Spatial location- usually geographic location • Information – visualization of analysis of data • System – linking software, hardware, data • Personnel – a thinking explorer with procedures using GIS to manipulate, analyze and present information

  14. GIS is a TOOL! • Displaying and editing data • Querying and analyzing data • Charting and reporting data • Creating layouts

  15. Data/Layout View Title bar Menu bar Standard toolbar Table of Contents Data Frame Layers Toolstoolbar Context menu Layout toolbar A tool that you apply …

  16. Components of a GIS

  17. Combining Data From Many Sources

  18. Data For GISApplications Business, Survey, & Demographic • Purchased, donated, free (Internet) • Created by user Databases -- Tables of data (such as address, permit, etc..) GPS -- Global Positioning System – Accurate locations Remote Sensing and Aerial Photography

  19. Where is GIS used? • Planning for government, education, & military • Environmental – Monitoring & Modeling • Public Safety – Fire, police & medical • Homeland security (first responders are local cities!!) • Business & Industry – Site Location, Delivery Systems • & much, much more …

  20. Concepts are most importantSoftware can be learned more easily • What remains constant: • GIS is a powerful tool • Mapping for Visualization • Spatial Analysis • What changes frequently • Data formats • User interfaces, inclusion of additional capabilities (e.g., 3D, spatial statistics)

  21. GIS strengths • More efficiently visualized updates • Easy and effective display • Good database management system for spatial information • Able to integrate data from many different sources (but…)

  22. GIS Weaknesses • Cost and difficulty of database creation • Higher accuracy, higher costs • Integration of data from diverse sources can result in poor overall accuracy if not well managed

  23. ArcGIS Desktop Licensing • ArcGIS is comprised of three levels of Licensing: • Arcview, • ArcEditor, • Arcinfo • Tool availability is dependant upon licensing type • Extensions have to be purchased at extra cost and do not come with the three basic licensing types

  24. What is ArcGIS Desktop ? • ArcGIS Desktop is an integrated suite of advanced GIS applications and interfaces, including ArcMap, ArcCatalog, ArcGlobe, ArcScene, ArcToolbox, and ModelBuilder. Using these applications and interfaces, you can perform any GIS task, from simple to advanced, including mapping; geographic analysis; data editing,compilation, and management; visualization; and geoprocessing. ArcGIS Desktop is scalable to meet the needs of many types of users. It is available at three functional levels: • ArcView focuses on comprehensive data use, mapping, and analysis. • ArcEditor adds advanced geographic editing and data creation. • ArcInfo is a complete, professional GIS desktop product containing comprehensive GIS functionality, including rich geoprocessing capabilities.

  25. ArcGIS Extensions

  26. ArcMapis primary display application, and perform map-based tasks. ArcCatalog is a window to browse and manage your data ArcToolboxis a set of tools for geographic process functions. ArcGIS Components

  27. ArcMapis the central component in ArcGIS Desktop for all map-based tasks, including cartography, map analysis, and editing. ArcMap is a comprehensive map authoring application for ArcGIS Desktop. ArcMapoffers two types of map views: a geographic data view and a page layout view. In geographic data view, you work with geographic layers to symbolize, analyze, and compile GIS datasets. A table of contents interface helps you organize and control the drawing properties of the GIS data layers in your data frame. What is Arcmap

  28. ArcCatalog helps you organize and manage all your GIS information (maps, globes, datasets, models, metadata, services, and so on). It includes tools to: Browse and find geographic information. Record, view, and manage metadata. Define, export, and import geodatabase schemas and designs. What is ArcCatalog

  29. What is ArcToolbox • ArcToolbox is embedded in ArcCatalog and ArcMap and is available in ArcView, ArcEditor, and ArcInfo. Each product level includes additional geoprocessing tools. ArcView supports a core set of simple data loading and translation tools as well as fundamental analysis tools; ArcEditor adds tools for geodatabase creation and loading; and ArcInfo provides a comprehensive set of geoprocessing tools for vector analysis, data conversion, data loading, and coverage geoprocessing. ArcView provides more than 80 tools in ArcToolbox, ArcEditor provides more than 90, and ArcInfo gives you approximately 250.

  30. Introduction to GIS • What is GIS? • GIS Software • Start Exercise

  31. Introduction to GIS: ArcMap • Data Frame (Map) properties • Settings for how map is displayed • Map units (feet, meters, miles, etc.) • Reference scale • Usually the scale that you will plot the map • Coordinate system • Automatically set to same coordinate system as first layer in table of contents. • Bookmarks • Create custom views of your map

  32. Introduction to GIS: ArcMap • Layer properties • Settings for how layers are displayed • Scale dependent display • Controls which scale a layer is visible • Data source • Symbology • Definition query • A SQL Expression that controls which features are visible in a layer • Labels

  33. Introduction to GIS: ArcMap • Data sources • Data layers are not embedded in the ArcMap project. • Data layers reference .shp files, geodatabase feature classes, coverages, CAD files or images • Standalone tables including .dbf, Excel or geodatabase tables.

  34. Introduction to ArcMap Find Parcel 047-332-002 What land use is it? (identify) Find intersection & Address Duarte St. and Eastern Ave. What water feature is near the parcel?

  35. Introduction to GIS: ArcMap • ArcMap • Selecting features • Set selectable layers • Selection tool • Add/remove features from selection set • Switch selection

  36. Introduction to GIS: ArcMap • Selecting features using Queries • Select by Location • Uses geographic relationships of data to select features. • e.g. Select parcels within city boundary • Select by Attribute • Uses a SQL expression to select features in the attribute table. • e.g. Select commercial parcels • Use Statistics • What is total? • What’s average size?

  37. Introduction to GIS: ArcMap Exercise: Combination query, attribute and location How many residential parcels within 1 mile of airport? (1,318) Create New Data Open Attribute Table Create Field and Calculate Sq. Ft. Export to Dbf. Open in MS Excel
