Beginning ArcMap, continued

You created and SAVEd a new page in /ghc/ called maps1.html, and that's where some of today's work will end up

Start
All Programs
Research Tools
ArcGIS
ArcMap

the application opens...

choose to open An existing map ...browse to your H:/ghc/ and open the .mxd you created last time, using the nitelitesgeog raster dataset.

To do the next steps you'll have to unmap and the remap a network drive:

Start menu
Right-click My Computer
left-click Disconnect Network Drive and choose the R: (probably has a red X)
Right-click My Computer again and left-click Map Network Drive...
select R: and type into the box \\acadproj\vol8
click FINISH

NOW you should be able to add data stored on the R: drive:

navigate to R:\ and choose the /esri2003/ folder
open the /world/ folder
double-click cntry02.shp to add it to the map
right-click cntry02 and left-click Properties...
in the Symbology tab, double-click the colored rectangle, and click 'hollow' and OK
click OK again

Add another layer:

from /world/, double-click cities.shp
right-click cities and choose 'Label Features' with a left click

Now SAVE the map you've made by adding the vector layers to the nitelites raster and close

Play around with the various features, changing colors (or whatever) and zooming in and out. When you have a map you like the looks of, choose Export Map... from the File menu, and save as a .jpg in your /ghc/ folder. Make a LINK to that .jpg file on your maps1.html page so everyone can admire your handiwork!

SAVE your map again, to preserve it at the state you've reached (you can always reopen it by entering from the Existing map file on your H:/ drive), and CLOSE ArcMap

Next: OPEN ArcMap again, choose 'New Map' again, and use the + (Add data) button to start a new map. Navigate to R:\global\ and double-click usinequal.shp

You'll see a map of US counties.

Right-click 'usinequal' and choose 'Open Attribute Table'... and look at what you've got to work with. Close the table.

Right-click 'usinequal' again, and choose 'Properties'. Double-click the 'Symbol' rectangle and change its Fill Color to 'No Color'. Click OK and then OK again.

Once again, right-click 'usinequal' and choose 'Properties'; click 'Quantities' and 'Graduated Colors'. Where it says 'Fields' and 'Value', scroll to the very last (GINQ2090)

Under 'Classification', change Classes to 20 and click OK

Use the magnifying glass to zoom to some part of the map that you're especially interested in

Add state boundaries: use the + button, navigate to R:\esri3\usa\ and double-click 'US States.lyr'

right-click US States, left-click 'Properties', select 'Features', and then change the Symbol color to 'No Color' and the Outline color to RED, and OK twice

SAVE this map with a new name, in your /ghc/ folder

Use the File menu to Export Map, saving it as a JPG file in your /ghc/ folder. Add this .jpg image to the maps1.html page. Write a brief summary of the patterns you see in this image... knowing as you do only the bits I told you on Thursday of what the data are that you're describing. You can learn more by looking at Gini Index overview ...and look also at comparison among nations. See INCOME INEQUALITY & DUALISM (François Nielsen) for more background.
