Lesson 6 Project - Map of Precipitation and Elevation in Oregon

Design a map that visually communicates Oregon precipitation and elevation data, and their connection, based on skills and concepts learned in Lesson 6. Fit it on an 8.5" x 11" page, and make sure to show:

  • contoured precipitation
  • tinted raster values of the precipitation data, with the color breaks corresponding to contoured precipitation intervals
  • either a legend interpreting precipitation, or labeled contours/classes on map
  • a second data frame (or inset) of Oregon at a size of your choosing that shows:
    • shaded relief (a hillshade image), and
    • hypsometrically tinted elevation
  • Also include title and other appropriate marginalia to complete the map

Note: for the second data frame, the shaded relief and hypsometrically tinted elevation should both be showing, so whichever one is on top will have to be partially transparent. We did not create tints with elevation data in this lesson, but it is simply symbolizing the grid that you made the hillshade from. Go into the symbology tab of the eagtopo30_grd and explore the color ramps available.  Remember that you can make your own color ramp very easily like we did in lesson 4. You can also right-click on a ramp and go to its properties to edit a ramp there. For hypsometric tinting inspiration view the examples at reliefshading.com, shadedrelief.com, and at www.maps.com. The first two are sites worth knowing about if you are interested in creating more shaded relief maps.

When your map is complete, export the following two versions of your map:

  1. Export your map as a PNG
    • File > Export Map...
    • Navigate to the appropriate lesson folder.
    • Name it "LASTname_FIRSTinitial_L6" (using your name).
    • Save as type: PNG.
    • In the expanded Options menu, on the General tab, set the Resolution to 100 dpi (Recall 72 dpi is suggested for online images, but 100 dpi will make the images a bit larger when viewed at full size. This will be useful for viewing each other's work.)
    • On the Format tab, make sure the Color Mode is set to 24-bit True Color.
    • Click the Save button.
  2. Export your map as a PDF (which I will use for feedback)
    • File > Export Map...
    • Navigate to the appropriate lesson folder.
    • Name it "LASTname_FIRSTinitial_L6" (using your name).
    • Save as type: PDF.
    • In the expanded Options menu, on the General tab, set the Resolution to 300 dpi (Recall 300 is most commonly used for print.  I will be commenting on the images onscreen, but the increased resolution will allow me to zoom in more, and allow you to print your map, if interested.)
    • On the Format tab, place a checkmark in the boxes to "Convert Marker Symbols to Polygons" and to "Embed All Document Fonts."
    • Click the Save button.

Submit both versions of your map via the Create Submission link at right (must be logged in to see link).

  • Select Lesson 6 Map for Assignment Type.
  • Enter name for Author.
  • Enter title of map.
  • Under Map Image File, browse for the PNG file version of your Lesson 6 map. Click Upload.
  • Under Assignment File, browse for the PDF file version of your Lesson 6 map. Click Upload.
  • Click Save.

Note: I will only publish your maps for each other to see after all students have turned in work, and possibly after you receive feedback. If you do not want me to publish your map, please let me know, but also remember that we are all here to learn and improve no matter where we are or what skills we have learned. Sharing work will help you learn about your own work, provide opportunity for further feedback, provide exposure to work of others, and provide opportunity to give feedback to others. Thank you for participating!

Reminder - Complete all of the Lesson 6 tasks!

You have reached the end of Lesson 6! Double-check the to-do list on the Lesson 6 Overview page to make sure you have completed all of the tasks listed there before you begin Lesson 7.

If you have any questions, feel free to post them to the Lesson 6 Discussion Forum.
