MIDTERM
Effective graphical representation of data seeks to inform an audience in a clear, simplistic manner. Your layouts will be evaluated on the basis of how well you convey fairly complex data into graphical forms that are both aesthetically pleasing and informative.
A
Powerpoint
presentation that briefly introduces the planning or policy issue that you have
chosen. Your presentation should includes between
four and eight different
layouts using at least six skills learned during class.
Each
layout should be somewhat distinct and should display your data in a
clear
and
uncluttered
way. Slide2
Boundaries are important
The “Clip” tool is your friend
Does this look right? Slide3
How clip works – the holiday cookie..
Input =
cookie dough
Clip features = cookie cutter
Output = Christmas tree cookie! Slide4
Use surrounding land features to fill in areas

Don’t create islands that don’t exist Slide5Slide6Slide7Slide8

What I DID NOT do
Get crime ratesSuccessfully teach myself to georeference an image using control pointsKeep my sanitySlide11
Low income areas are concentrated:
East LA South LAThe Valley
Aggregated field creation:
(public assistance+SSI) / Tot. Pop.

Poverty is centralized in the same areas that people receive the most public assistance.

FINAL
POLICY QUESTION: What district-wide, violence prevention policy can LAUSD middle and high schools utilize to help educate students on the skills needed to prevent violence?
FIRST WE MUST KNOW
What are the demographics of LAUSD schools?Where is violence centralized in LA County?What are the needs of LAUSD students?Slide15
Skills
Inset Map: LAUSD MapPoint graduated Symbol: displayed the number of drop outs in LAUSD high schoolsAggregating attribute fields: adding together public assistance and SSI and then dividing by the total pop. Per census tract. Attribute Subset Selections: selected LAUSD schools from all LA County Schools, selected major Interstates from an LA County roads shape file
Create Indices:
Calculated percent of people that receive public assistanceAttribute sub-set selection: Selected City of LA from LA County Places for all maps. Selected interstates from LA County roads for all maps.Geocoding: Created address locator for LAUSD High Schools and Middle Schools. Geoprocessing: Clipping: Clipped LAUSD from County of LA school districts, clipped interstates to LA County, Clipped LA County from CA Counties, Slide16
How do coastal cities impact beach water quality?
Christine M LeeCivil and Environmental EngineeringSlide17
Santa Monica Bay spans between 50-60 miles of the Los Angeles County coastline.Slide18
Heal the Bay regularly monitors 61 beaches in this region (and more if we go farther south)Slide19
These coastline communities were defined using a 1 mile buffer; however, visitors often travel much farther than this to access the beach.Slide20Slide21

Questions to ask yourself about your map
During my presentation, how much will I need to explain my map? Your key point should not require any explanation; it should be apparent to the audience.Does my inset map effectively put the study area in context?
No new islands!
Do my labels distract from the main point I am trying to show on my map?Play with the color and size of your text so important labels ‘pop’ while secondary labels fade into background. Be picky about what labels and text you include; the image should be your main method of communication, not text!
Does my presentation flow?Make sure you are using the same graphic ‘language’ from slide to slideGenerally speaking (but not always) your legend, sources, north arrow and other information should be shown in the same area from slide to slide. Your maps should be able to ‘stand alone’ AND build on each other throughout the presentation.
