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

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 ArcCatalogand ArcMap, which will be used extensively in the lab.

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

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

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 ExercisePart 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”

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

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
