1 Review of File Management and Introduction to ArcGIS RNR/GEOG 417/517 Overview of Presentation Discuss the objectives of the lab exercise Introduce the class directory structure General file policies Introduce ArcGIS ArcMap interface ArcMap functions Overview of the lab exercise 1

2 Objectives of the lab exercise Verify basic digital file management practices File creation, edit, and management Provide an overview of the functionality of ArcGIS desktop GIS Explore digital geospatial data Geographic feature representation Related feature attributes Provide some hands-on experience in query, display, and edit of geospatial data Develop familiarity with the applications ArcCatalog and ArcMap, which will be used extensively in the lab. Get to know the course file system user areas PowerPoint data folder 2

3 General File Policies Always submit a readme.txt file Use only this file name, not variants Place it where you are instructed Presence of this file is part of score for lab Never use spaces in file or folder names Always be sure your files are in the correct location Backup your files USB drive What it is: What is ArcGIS? A system of software applications for enterprise GIS What it is not: A single software product 3

4 ArcGIS Applications ArcGIS consists of two main applications ArcCatalog ArcMap ArcCatalog View GIS Data Holdings Preview Geographic Table 3D View/Edit Metadata Work with Tables 4

5 ArcMap Perform map based tasks Mapping Editing Queries Analysis Charting Reporting ArcMap Interface Menu Bar Standard Toolbar Title Bar: Shows Map Name Table of Contents: Data Views and Layer Legends are Listed in the Dockable Table of Contents Context Menus: Right-click Data or Layers Sizable! Drag divider Status bar: Describes Selected Buttons and Menu Items; Reports Coordinates Display Area: Map Features Draw in the Display Area 5

6 Table of Contents Drawing Order Drag Layers To Reorder Show, Hide, Remove Layers Rename Objects View Source Data Layer Context Menu Layer Symbology and Color Viewing a Map Layout View Work with the Map Page (Place Map Elements) Data View Work with the Data (Edit Features) 6

7 Layout Elements Data Frames Legend North Arrow Neatlines, Guides, Grids Scale Bar Scale Text Pictures OLE Objects Data Frames Containers for Layers and Graphics Have Indexes and Graticules Have a Coordinate System Projection On-the-fly First Layer Sets Default Layout View USA Data Frame (Albers Equal Area) World Data Frame (No projection) 7

8 Data frame properties Units Frame and Background Symbology Coordinate System Illumination Grids Labels and Annotation Show Extents for Other Data Frames Layout View View Multiple Data Frames All Interactive Tools Work in Layout View Pan, Zoom, Edit, Labeling Page-centric Tools Zoom %, 1:1, Zoom to Paper 8

9 Maps Contain Layers Layers Have a Data Source Layers Have Symbology Layers Can be Saved with a Map (USA.mxd) Layers Can be Saved as a File (Streets.lyr) Layer Properties General Source Selection Display Symbology Visibility Fields Definition Query Labels Joins and Relates 9

10 Layer Properties Setting Visibility Scale Minimum Display Scale Maximum Display Scale Visible scale Layer Properties Symbology Right-click a Symbol to Set its Color Left-click to Change Symbol Properties 10

11 Page Setup Dynamically Resize Page Create Printer- Independent Pages On-the-fly Raster Resampling for Faster Printing Adding Layer Data Using ArcCatalog Drag Data from ArcCatalog to ArcMap Using ArcMap File>Add Data Table of Contents Add Data Button ArcMap Generates a Layer for Data Added 11

12 Map Interaction Identifying a Feature Identify Features Across Layers Search Tolerance Identify Options Set Bookmarks Add Hyperlinks Map Interaction Finding a Feature Search All Layers Selectable Layers Specific Layer Result Options Flash Zoom Identify Set Bookmarks Select the Feature 12

13 Storing Map Documents Saved as.mxd File by Default Can Save as a Template (.mxt) Can Store Relative or Full Path Names File > Map properties > Data Source Options Overview of Exercise Part One: file creation and management Create a new directory in your user area Find the class data directory w:\rnr417\rnr417data Copy the ASCII text file read.me to your new directory Edit the file as directed (note the format of the file) Save file as readme.txt Your Name Lab Section Number Lab Assignment Number FILELIST Name Type Description readme.txt ASCII text file delivery documentation 13

14 Overview of Exercise Part Two: ArcGIS Exercises Copy the exercise folder from [drive]:\rnr417\rnr417data to your new lab2 folder Folder contains a map document (mxd) and some spatial data Complete the activities in the lab assignment Overview (part 2, continued) Navigate to the copied map folder and open the file qstart.pdf Do not use the default path specified in the tutorial Place all output files in your map folder Do not print any maps (skip those instructions) Manage your windows using the taskbar 14

15 Deliverables Completion of all steps in the Instructions section of the assignment One readme.txt file (ASCII text) in your lab2 folder that describes the contents of the exercise folder Due next lab period 15
