Administrative:
    (1) Tell us if you did *NOT* get class email today
    (2) We will meet in W31-301 on Mondays 2:30-5:00 for lab
	    and in 14E-310 on Wednesdays at 2:30 pm for lecture

LAB #1:  http://mit.edu/11.188/www/lab1
    (1) Understand basic setup of machines and ArcMap
    (2) Experiment with basic GIS functions and analysis
    (3) Prepare PDF 'printout' of thematic map of Cambridge

Getting into the 9-251 computing lab: (another place where you can do class exercises)
	Combo is different from MIT public clusters: <<< combo given in class >>>

WinAthena PCs:
	login, your MIT "Athena" home directory is on Drive I:
        (Drive H:\ is your locker for Windows-specific stuff)
	Find class locker in either of two ways:
		(1) in Z:\athena.mit.edu\course\11\11.520
		(2) in Drive M after you run this command in a DOS window
			net use M: \\afs\athena.mit.edu\course\11\11.188
		[ makes Drive M: = /afs/athena.mit.edu/course/11/11.188
		  datasets: mostly in M:\data ]

Datasets:
	shapefiles: e.g., cambbgrp.shp (one name, many files)
	  [ArcGIS also supports 'coverages': this file format stores geometry in a 
	   coverage folder, and attributes in 'info' folder]
	Access ArcGIS datasets via the ArcCatalog tab along right side of ArcMap or
	   use the Windows/Catalog choice from the main menu
	Copy all sizeable datasets into C:\temp before using them in ArcMap
	-- Use ArcCatalog to copy shapefiles and coverages
	-- OK to use Internet Explorer for copying if entire workspace is copied 


ArcMap: (key elements of Lab #1)
	Map window: experiment with buttons and geometry/attribute links
	Layer properties: experiment with thematic maps, symbology, ...
	classification: think about choices 
		-- quantile, equal interval, ...
		-- be sure to look up description of classification choices in ArcGIS Help    
	Saving & Printing:
		-- ArcMap - View as 'layout'
		-- save PDF copies of what could be printed; 
		-- See Pharos and CRON instructions for actual printing
		
Google Earth: 
	Think about what Google Earth needs to know in order to overlay your map
	Edit properties of your overlay and set transparency to 50%
	Zoom in/out and pan around to see the accuracy and perspective changes

Software on your machine:
	Download ArcGIS 10.1 desktop software from: 
		http://ist.mit.edu/software-hardware?type=27 (MIT certificate required) 
		or during lab from our external USB drive
	  Also need: (see http://ist.mit.edu/software-hardware)
	  	Kerberos for windows 3.2.2 or later
	  	VPN Client (Cisco AnyConnect VPN)
	For AFS file access:  http://openafs.org
	
	Mac alternative: Citrix server (https://citrix.mit.edu/)
