This lab will help you get familiar with ArcView 3.0b.  ArcView 3.0b is on alai.la.asu.edu so you will need to use eXceed to establish an xterm connection to alai. There will be a set of files in your directory that you will use to complete the assignment.  Remember the lectures in which we talked about UNIX and the Xwindows system.

Connecting to alai.la.asu.edu
1) Find the alai.xterm icon on the PC side of the desktop and doubleclick, and then give your userhane and password for that machine. IF you have forgotten, ask George or Ramon.
2) TYPE ONLY ONCE:
ln -s ~slugg/glg490 gisdatasets
3) TYPE EVERY TIME you login:
source /etc/cshrc
4) To launch Arcview:
arview&

Lab notes for running ArcView:
General activities:
Turn the themes on and off, and change their order and layering.
Add different themes; be sure to change the Data Source Type to Grid Data Source (Digital Topography), Image Data source (Airphotos), or Feature Data source (Geology coverage).
1) To show the Digital Elevation Model, click on Project window, and then under File menu, select extensions, make sure that all of them are clicked.
2) To show the Digital Elevation Model, click on add theme under the view menu, change the Data Source Type to Grid Data Source. Then select Cupertinolat, and you will have a them that is the topography. Once you have selected the theme (not just checked, but also selected), you can perform analyses such as computing slope, hillshade, contours, etc.

3) Making printable maps. Click on Project window, and then click on Layouts and then New. Note that a new window appears.
Note a World symbol on the toolbar appears. Use the tools there to place your View onto the layout, or the North arrow, Legend, scale, etc. All of those tools are available under the World tool on the tool bar when you are working on the Layout.
To fix the scale, go back to the View on which you have been working, and under the View menu, select properties, and then chnage the Map units and the drawing units to meters.
4) Be sure to save the project to your home directory. All of the other datasets that you have generated such as the hillshade and the contours will be saved to your home directory, while the other prepared datasets stay in George's directory, to which they are linked via the gisdatasets directory in your home directory.

The following is a list of files that you will be using for this assignment:

Geology.shp -- The geology of the Rancho San Antonio Study Site
Hydrology.shp -- The surface hydrology of the Rancho San Antonio Study Site
cupertinolat -- The Digital Elevation Model (DEM) of the Rancho San Antonio Study Site
cupertnw1.bil -- Northwestern quarter of the Digital Orthophoto Quadrangle (DOQ) of the study area
cupertne.bil  -- Northeastern quarter of the Digital Orthophoto Quadrangle (DOQ) of the study area
cupertse.bil --  Southeastern quarter of the Digital Orthophoto Quadrangle (DOQ) of the study area
cupertsw.bil -- Southwestern quarter of the Digital Orthophoto Quadrangle (DOQ) of the study area.
 

What you are to do:

1)  Add the geology theme to your view and edit the legend to create a set of aesthetically pleasing colors.  The theme's colors should be based on the "Agelith" field in the theme.
2)  Add the surface hydrology theme to your view and edit the drawing.  The theme should be designated as a "Single Symbol" theme.  Make the lines blue.
3)  Add the digital topography as a Grid Data Source theme to your view.
4)  Add the digital orthophoto quadrangles as Image Data Sources themes to your view.
5)  Using the analysis tools, derive a hillshade for the topography based on the digital topography.  Try several values for the sun's position in the sky to create a demonstrative hillshade.
6)  Using the analysis tools, create 5 foot, 10 foot, and 50 foot contour lines based on the digital topography.
7)  Create a layout that includes the Hydrology, Geology, and Contour data.  The layout should include a title, a north arrow, a key, and a scale.
8)  Create a layout that shows the hydrology on top of the Digital Orthophoto Quadrangle and Contour data.  The layout should include a title, a north arrow, a key, and a scale.
9)  Create a layout that shows the hydrology and contours on top of the hillshaded theme.  The layout should include a title, a north arrow, a key, and a scale.
10) Based on your analysis of these data, where would you infer that the faults are, and are they still active?

Save the project on your home directory on alai.  When you are ready to submit this assignment, send email to glg490@asu.edu to tell us the name of the file on your home directory which is your project assignment. Include the answer to #10 above in your email.
