They represent data, data analysis, and data output/mapping. Extensions are add-ons that increase the capabilities of ArcGIS. Digitizing and raster analysis are examples of extensions. Another point to note about ArcGIS is that it give you the ability to convert data between one format and another, and to reproject data.PART 3: Google EarthIf the lab computer does not have google earth, go to http://earth.google.com/ where you can download it for free to your personal computer.Spend a few minutes exploring and searching at home. Type in your address. Type in a country name.Know and remember for future assignments than in ArcMap, you can export maps to Google Earth. This requires that you convert the Arc file into a “kmz” file. Instructions as to how to do this can be searched for on the web. You will not be asked to do that as a part of today’s exercise!Please complete the questions on the following page and save them to your class folder within a folder named Lab1. Remember that the “modified date” of the write-up file is being used to determine that you have completed the lab on time. Therefore, be certain not to make changes to your lab write-up after the date the lab is due, because this will change the modification date of your lab write-up and will make it appear late. Late labs will be assessed a 10% penalty per day. You may use classmates as resources for questions, but all lab work must be done independently. Lab partners/lab groups and joint write-ups are not acceptable.Geography 370Lab #1 QuestionsGEOG 370 – Spring 2008Lab #1: Introduction to UNC Network Computing and GISDue Dates: Tuesday Labs: Tuesday, January 22, 2008 by 11:00AMWednesday Labs: Wednesday, January 23, 2008 by 2:00PMThursday Labs: Thursday, January 24, 2005 by 11:00AMPART 1Introduction to the Server at UNCThe purpose of this part is to introduce you to the structure of ISIS, the server that wewill be using in the lab portion of Geography 370. During the semester you will be using a program called ArcMap to learn about GIS. Thisprogram is stored on the central UNC Server. It is imperative that you understand this lab,because you will need to understand how the server is set up and where the various filesyou'll be using are located. You will also need to know where to save your work.Academic Technology Networks (ATN) manages all of the computer labs at UNC.Because ATN manages all the labs, there is a consistency to the computers no matterwhich lab you use. So the following information should apply no matter what lab you arein. *If for some reason you do not have an onyen, go to http://help.unc.edu/ and get one now.Introduction to Computers in ATN LabsLogging in:The one thing that you will notice when you sit down at the machine is that you have tologin before you can begin work. Type your ONYEN ID in the user id space and put yourONYEN password in the password space.Saving Files:This will be discussed in greater detail in the Folders Section and in the SoftwareSection, but briefly stated, you should save your work on either network space (H:\ or J:\)or a personal flash drive. Our class space should be “mapped” to the M drive.*DO NOT save your work on the computer's local hard drives (C:\ or D:\)!!Applications:All machines in every lab should be able to run ArcMap. There are two ways to startArcMap: (1) From the Start Menu (bottom left hand corner of screen)Select programs. Then GIS applications and then ArcGIS. You should find ArcMap.(2) From a Folder on the Desktop* *Having a GIS folder on the Desktop will vary from lab to labMeet IsisUnderstanding which folders you should save your work to will save you headacheswhen it comes time to turn in your lab. All of the computers in ATN labs are connected to a collection of computers that areknown as "ISIS". For simplicity's sake, think of this group of computers as one bigcomputer. There are a lot of things stored on Isis, many different application programs(ArcMap being only one), as well as countless files and directories. Every person whohas an ONYEN ID has a folder where they can store files and set up directories, and evenset up web pages.There are countless folders on ISIS, most of which you'll never have to worry about.There are three however, that are important. 1. The folders where you will go to get the data for the lab2. The folders where you will put your completed work3. The folder where the applications are.Below is a simplified picture of the structure of ISIS, showing the three foldersmentioned above. 2Address of course information: J:\isis.unc.edu\html\courses\2008spring\geog\370\006You can use the My Computer icon to navigate to the class course materials. Doubleclick the icon. Then essentially follow each piece of the address. Click on the J: drive,then isis, then html, then courses, then 2008spring, then geog, then 370, and then 006.This is the main folder for our class. In it will be sub-folders containing data for each lab as well as individual folders for each student (within a \students sub-folder). Mapping the drive:!!!!You must do this for every computer for which you do work for this class becauseof the structure of ArcMap!!!Go to the AFS Client (the lock icon on the lower right hand side).Click on the Drive Letters tab and select the add button.3 ArcMap) are storedSelect drive letter M and type in the path:\afs\isis.unc.edu\html\courses\2008spring\geog\370\006There are two areas of the class space you will need to become familiar with: 1) The space where lab data will reside2) The student space that you will create1) DataData for the labs will be stored in J:\isis\html\courses\2008spring\geog\370\006\data 2) Your SpaceEach student in Geog 370 will create a folder where they can save the lab assignments.The only people who will have access to this space are the instructor, the TAs and theperson whose ONYEN is on the folder. Students do not have access to each other’sfolders. The location of your folder will
