GIS SHOWCASE: Examples and Resources for Mapping June 26, 2009 Madhu Lakshmanan, LSNTAP
Welcome! If you joined the conference via telephone, please enter your audio pin if you havent already. (The image on the right is an example - your audio pin will be different.) If you joined with a microphone and headset or speakers (VoIP), please be sure your device volume settings are properly adjusted. If your mic & headset is not working, please try unplugging and re-plugging in your device. We will begin promptly at the top of the hour.
Please, let us know your questions and comments during the training Maximize/minimize your screen with the chevron symbol Telephone participants need to enter their audio pin Ask a question in the questions log Raise your hand
Ensuring we can hear you Mic & Speakers users should make sure the microphone volume is turned up. You can always switch to telephone at anytime in the training. Ensure that you have not muted yourself Un-mutedMuted

Todays Presentation Brief introduction Examples from LSNC The Elderlaw of Michigan Experience Getting started with mapping today! Some possibilities Resources
Mapping & GIS A geographic information system (GIS) captures, stores, analyzes, manages, and presents data that refers to location. Mapping is the commonest way of visualizing GIS data. GIS infrastructure, hardware & software are one of the most complex, expensive and dynamic systems now. Decent basic customized systems would run into the 6 figures.
Mapping @LSNC Early adopters and one of the most sophisticated users of GIS in our community.
Using Maps as an Advocacy Tool NTAP Webinar June 26, 2009 Legal Services of Northern CA www.lsnc.net
Why use maps and visual data? A picture is worth a thousand words A picture is worth a thousand words Myth of objectivity Myth of objectivity Makes concepts and certain phenomena visible, e.g. structural racism Makes concepts and certain phenomena visible, e.g. structural racism
Legislative advocacy: Fighting health care cuts
Applying the data and map presentation tool Maps are an advocacy tool Maps are an advocacy tool Use data of opponents and detractors to make your case Use data of opponents and detractors to make your case Maps/compelling data presentations to foster collaboration, problem- solving Maps/compelling data presentations to foster collaboration, problem- solving Maps/data in litigation and other adversarial proceedings Maps/data in litigation and other adversarial proceedings

Mapping @ Elder Law of Michigan Trying to use mapping for targeting services and evaluation.
The process What do I want to do? Map my sample New Mexico case data and also analyze it vis-à-vis the population of senior citizens in that state. What do I need? A mapping application (Google Earth) KML/KMZ files from the census for NM seniors & for my case data Geocoding service (to add lat/long to case data) KML creating application from census data Optional graphing tool
http://ctasgis02.psur.utk.edu/tokml/Default.aspx Online Tool to create KML files from Census data
Using case data A concern for mapping case data directly always remains that of confidentiality. Geocoding your case data would require you to get coordinates (lat/long) for the address portion of your data and you dont need to send any other information to the geocoder. It is exactly what you do when you type addresses into MapQuest or into your cars GPS system to get you somewhere. Aggregating case data by zipcode would be almost as useful in showing you density on a map while preserving confidentiality of a specific case address.
Add lat/lon information to your case data @ www.batchgeocode.com You can download a KML file with this data.
Census data overlaid with case data directly in Google Earth
Case data by zipcode aggregate The size of the blue circles is proportional to the number of cases in that zip code area.
Individual & aggregate representation of case data

Upcoming… Hands-on multi-part trainings using the process outlined here. Increased content in the lsntap.org tech library The GIS list revived! Support @ the helpdesk for mapping
