1. User Account
In order to use the GIS lab facility, you need a user account for accessing GIS Lab file server and terminal servers. You must have a UNBC user account set up by ITS (Computing and Telecommunications Services) before applying a GIS user account.
- To get a UNBC account, go to the ITS help desk located the north end of the second floor in the Teaching Lab building.
- If you do have an UNBC account but do not remember your account information, check it out at http://www.userdb.unbc.ca
- Take your UNBC account information to GIS Lab and talk to a Senior Lab Instructor (Ping or Scott). The lab instructor will set up an account for you for accessing GIS facility.
Note: User account should be done in the first week of each semester if you are taking GIS related courses.
2. Lab Protocol
- NO food, drinks, or eating and no sound systems or radios beyond the lab entrance.
- YOU MUST consult a lab instructor before switching on or off a computer.
- Do not touch the computer screen. Use your mouse pointer to point things out to other people.
- You should stay in your assigned lab period. However, if you must switch for a week talk to you lab instructor.
- When you finish your work in the lab time, please close all windows (programs) and logout properly.
3. Lab Schedule
The GIS LAB is open from 8:30am to 4:30pm, Monday – Friday. The lab schedule is posted on the board outside of the GIS Lab and also on our website. Time slots that are not occupied by courses open to everyone.
4. Lab environments
All the lab machines in GIS Lab are dual booting operating systems: Ubuntu Linux & Windows. The default system is Ubuntu Linux. Each lab machine generally is running as a client to access our servers:
|Servers in GIS lab||Description||Usage|
|osmotar.unbc.ca||GIS Window Terminal Server (window sever)||Running the software for window platform|
|pg-gis-lnx-01.unbc.ca||GIS Linux Server||Running the software for Linux/Unix platform|
|ninkasi.unbc.ca||GIS File Server||GIS File Server for data and files access|
GIS Terminal Servers are running window 2008 sever system and act as processor servers. All software for window platform is running on GIS Terminal Servers. The software for Linux/Unix platform is running on GIS Linux Server. The Ninkasi is running Linux system and acts as a file server for files and data access.
The following picture shows the working environment in the GIS Lab.
We have dual booting system (Linux & Windows) for each lab machine; the default operating system is Ubuntu Linux.
Lab machines – Ubuntu Linux
The default login window is Ubuntu Linux. To login to GIS Lab machines, enter your user account name and password. After a while, you will see GUI interface displayed. The icons on your desktop allow you to access GIS terminal servers (Remote Desktop).
Lab machines – Windows
To switch between two operating systems on lab machines, you need to reboot computer by clicking SYSTEM->Quit->Restart Computer on the menu bar located at bottom in Ubuntu Linux or Turn off Computer -> Restart in Windows. A menu screen will pop up to allow for selecting the operating system (Note: this only exists for a few seconds). Use the Up and Down arrow keys on the keyboard to choose the system you want to boot to.
If you choose to boot to Windows on the local machine, the login window will pop up, click GISuser icon to login as gisuser. The password will be provided by your lab instructor.
- Course materials including the lecture notes, lab manual, help and more information and resources related to GIS and Remote Sensing are available at our GIS Website.
6. Connect to Windows Terminal Server
In general, all lab machines are used as a client machine to access GIS Lab servers. In most cases you need to access either GIS Window terminal servers or GIS Linux Server through the local machines. GIS Windows Terminal Servers have most popular window software installed, such as
- Microsoft Office
- OziExplorer & Ozi3D ….
Connect to Terminal Server from GIS lab machines
- To connect to a window terminal server, double click the GIS Terminal Server icon (for osmotar) on your desktop in Linux or double click GIS TServer icon in Windows. The login window will popup allowing you to enter the account informaiton.
Connect to Terminal Server from office machine or home computer (WindowsXP/7)
- If you work from home or your office machine, click
Start -> All programs -> Accessories -> Remote Desktop Connection
- In the popped up login window, make sure osmotar.unbc.ca is set to Computer and click Connect button (image left below)
|In window environment||In Linux/Unix environment|
- Login the server with your UNBC account
7. Mapping GIS file server NINKASI in window environment
All files and data are stored in GIS Lab file server Ninkasi. To access the file server Ninkasi, you need to map a network drive in a window environment to Ninkasi.
Mapping Ninkasi server from Terminal Server and Windows XP/7
- Click Start -> Computer
- Click Map Network drive at top
- In the popped window, choose letter N for the drive letter, set \ninkasihome for the Folder (server path).
- Make sure the check box beside Reconnect at logon is check. This will result automatic connection when you login to terminal server next time. That means you need only to do this at the first time you login to terminal server.
- Select Connect using different credentials and check ‘Remember my credentials’.
- Click FINISH button.
You will be asked to provide user account information. The user account information here is your UNBC username and the your UNBC password (Samba password you got from lab instructor to access Ninkasi)
- Place a check mark for ‘Remember my credentials’. This allows system to remember your account info and wouldn’t ask you next time you login in.
- Click OK. Once you made the connection, a window will pop up where all users’ home directory on Ninkasi are listed here. (You should be able to find out your home directory on Ninkasi server). Click X at upper right corner of the window to close it.
- Now back to My Computer window, you should see a mapped network drive “home on ‘Samba2.2.1a(Ninkasi)(N:) listed in the catalog tree. The drive N is the access point to Ninkasi server.
8. Starting GIS software on the Windows Terminal Server
Two major ArcGIS applications: ArcCatalog and ArcMap
- To start ArcCatalog, click
Start -> All Programs -> ArcGIS -> ArcCatalog
- To start ArcMap, click
Start -> All Programs -> ArcGIS -> ArcMap
Remember to close all programs and logout from the server once you have done your work.
- Click Start -> Logoff from the server window to logoff from the terminal server.
- Before logout, please close all programs running on the system.
- To logout from terminal server click Start->Logoff
- To logout from lab machine simply click System->Quit -> Logout in Ubuntu Linux.
- To logout from Windows click Start -> Logoff
