Introduction to the Geography Computer Network Dr Andrew Klein Introduction In the beginning of the lab the Teaching Assismnts will guide you through learning how to login to the Geography Departmenfs computer network navigate our directory structure and make sure that you have the appropriate printers installed on your account After this week your TAs have been instructed to assume that you understand the basics of the Geography Computer Network and they will be moving on with instruction in GISsci THERE IS SIMPLY NO WAY YOU CAN LEARN GIS WITHOUT UNDERSTANDING THE BASICS OF THE COMPUTER SYSTEM YOU ARE WORKING ON The Geography Computer System The computers that you will be using in this lab run the Microsoft Windows XP operating system There are two things of special note The first is that all computers are networked together Second the lab is setup with a server Our server is known as GEOGSTUDENT and it is where in your home directory which we often call your H drive you are to save all your work DO NOT SAVE YOUR WORK ON OTHER MACHINES OR IN OTHER DIRECTORIES AS YOUR WORK MAY DISAPPEAR All the computers have ENVI insmlled so it does not matter which machine you use Login to the Geography Computer Network In order to use the GIS computers you must provide a valid LoginID and Password The same login will work on all the machines Your LoginID and password have already been created for everyone in the class and will be provided to you Everyone should try to login and if you encounter any problems let your TA know Your Home Directory Every student has a home directory also known as a folder The home directory is physically located on GEOGSTUDENT computer However to make things easy it will appear on every computer you login to as H The H drive points to your home directory so everyone39s H will be different This is done to assure user privacy You should navigate to the correct location and determine if your folder exists If your folder does not exist then please inform your TA The Windows XP Desktop After you have logged in you should familiarize yourselfwith the Windows XP desktop There is gray bar with a START button on the bottom Placing the cursor over the button using the mouse and clicking the left mouse button should bring up a set of options In the Geography computer network most of the commonly used programs can be accessed under the Apps Menu An example showing how to start ENVI is shown below R1ght7cl1cl 1ng wh1le the cursor 1s over My Computer w11l br1ng up a set of opt1ons Selecttng Explore w111 start Windows Explorer Th1s program w1ll allow you to eas1ly see how the network 1s set up and allow you to move between mach1nes and folders on rnachmes You can also nav1gate around the systems by usmg the 1cons 1n the upper left corner By the t1rne you leave you should be very comfortable with the computer system so in the future you can locate the les and folders you need Connecting to the Class Share containing Lab Exercise Maten39als The laboratory exerc1ses 1n th1s class w1ll make use ofrernote sens1ng 1mages and other Lnforrnatton that have coranled for your use In order to gam access to the class shares along w1th

to connect to the easiestway is to simply select a drive letter designation U and specify the folder we want to connect to You must also make sure this drive is reconnected each time you log into the network by checking the appropriate box To map the network drive simply fill in the required elds as shown below Map Nelwnrk Drive E Wndaws an nab yau tanner la a shaved netwmkfa dev and man a dee

known as the 83 naming convention The rst 8 characters were the lename and the last 3 characters were the extension often a smndard abbreviation describing the le type While recent versions of the Windows operating system and Unix Linux and the Macintosh operating systems allow many more characters than original 83 some ArcGIS functionality requires the 83 convention so whenever possible you should stick to the 83 naming convention to minimize problems It is a good skill to learn to recognize what le types usually distinguished by the XXX extension are associated with what programs Note that some common le extensions such as z39mg may be used by more than one program File Type Extensions Some Common Files Types Text Files txt Comma Delimited les csv Microsoft Word Files doc Microsoft
