ASSIGNMENT
You may do the first two parts of this week's assignment in pairs or groups of three. These parts should be turned in on paper at the beginning of class next week. The third part, you should prepare individually and bring to class next week.
Part 1 - simple spatial analysis
  1. Using the ArcView_week3 database on the PrintServer in the /Data/Classes/LARP601/ folder, open up the geocode.apr project. If you did not do so in class, please geocode the table you brought to class. Remember that to geocode your address, you will need to index the Phila_Streets theme if you have not already done so. Leaving the Geocode to Streets view open, open a new Layout. Open the Layout > Page Setup menu item to confirm that this layout is on letter size paper and in portrait orientation. Draw a View Frame in the Layout and select your Geocode to Streets view to fill it. Now draw a Table of Contents Frame, adding a legend to your Layout. Using the Text Tool, add a Title to the top of the sheet. You may need to open the Symbol Window to adjust the Font Size or Typeface. Draw a North Arrow Frame and Scalebar Frame in an appropriate location. Using the Text Tool again, make a note on the bottom what your geocode match rate was and any other notes you feel necessary. Finally Print the Layout.
  2. Close your Layout and the Geocode to Streets view. Open the Philadelphia Natural Hazards view. For this part, let's imagine that you have been hired by the Parks and Recreation department. Several of the hospitals in the area are interested in initiating a 'Therapy in the Parks' program in which they will take patients to woods and meadows with the idea that communion with the organic environment will speed their recovery. However, they for logistical reasons, they cannot go more than 1000 feet from any of the hospitals. In this view, you have a Land Use theme that will tell you those area with Woods ([lgds_text]="12") or Recreation ([lgds_text]="9") land uses.

    Open the View Properties dialog box and note that while the map units are in decimal degrees, the distance units are set to feet. The feet units are what you will use to draw a buffer. First use the Select Feature Tool to select all of the Hospitals. Next select the Feature Buffer button on far right side of the button bar. It will prompt you for a buffer. Enter 1000 (for the distance from each hospital). Answer Yes to the next question (this will dissolve the extra lines of any overlapping buffer circles). If you zoom in to some of the hospitals, you will now notice that they each have a circle drawn around them. Notice that the circles have been drawn as graphics on the screen rather than as a new theme. Use the Pointer arrow to select these buffer graphics. Next make the 'Land Use' theme active. If you look to the upper right of the button bar, you will notice the Select Using Graphic button has become active. With the Land Use theme actice, hit this button. The result should be a land use map with those areas inside or touching the buffer highlighted in yellow. However, this has selected all of the land uses within a 1000 ft and we want just those that correspond to Recreation and Wooded areas. We can subtract from this selection set with the Query Builder. Using the Query Builder, construct a query on the Land Use theme that selects Woods ([lgds_text]="12") OR Recreation ([lgds_text]="9") but rather than selecting the New Set button, select the Subtract from Set button. The final result should be map that has the Wooded and Recreation areas within 1000 ft from a hospital. See if you can get this into a new Layout and print it out. You may need to adjust your layers and colors carefully with the Legend Editor to have it appear properly on a B&W laser printer.
  3. The third View I found on the internet and imported it. I just thought it was kind of cool.

Part 3 - prep for 3D modeling
  1. You should each do this part individually.
  2. Please bring to class a drawing of a simple site design. It could be a plaza, a small garden, or almost anything. It should be relatively small scale without large numbers of elements. It should also be relatively flat (we will get into the landform part later). It should be measured and scaled in a way you will understand. It might be an old site design. It might be a simple sketch on the back of an envelope or a piece of trace. The quality of the media is not important at this point.
  3. You will begin drawing this simple site design using FormZ next week in class.
