11.188 Labs #3:  In-Lab Notes on Feb. 24, 2014]

REMEMBER HOMEWORK SET #1 DUE Wednesday, MARCH 6

LAB #3: Spatial queries and joins
  (1) Main Idea: Compare Cambridge housing prices with the 
      socio-economics of the neighborhood and proximity 
	  to Mass Ave
  (2) Add new columns to data tables
  (3) Merging, editing, saving data (e.g., to compute
      the percent with high school education)
  (4) Spatial joins to find neighborhood containing each sale
  (5) Buffering Mass Ave and comparing sales prices of 
      housing that is close/far
  (6) Extracting Mass Ave street segments with a specific coordinate system
  (7) File locations and ArcMap startup: 
      -- Checking ArcMap's 'scratchspace' location to avoid performance problems
	  -- You can start this week's lab with the same 11.188_lab2_web.mxd document
         and shapefiles as were bundled into the zipped cambridge_shapefiles for 
         last week's lab.  That way, you will have the MassGIS and ESRI web 
	     services and you can add the additional shapefile (middle_county.shp) 
	     after copying  it to c:\temp.

Homework grading:
  A. Some comments have been posted for Lab #1 - review them to see what
     we want for a basic map to be readable and meaningful.
  B. Note, for lab #1 we do not emphasize readability of maps, but we will
     from now on
  C. Lab #2 deadline is extended 24 hours (to 2:30 pm tomorrow)
     so you can tweak your submission based on Lab #1 feedback
