today! Some possibilitiesResources

Mapping & GISA 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 @LSNCEarly adopters and one of the

most sophisticated users of GIS in our community.

Example

Data created using Map

Getting started with mapping today

Google Earth – Quick look

The processWhat 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

Google Earth- Census data

Using case dataA 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 don’t need to send any other information to the geocoder.

It is exactly what you do when you type addresses into MapQuest or into your car’s 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

Raw case data to aggregate data

EarthPlot – aggregate data on a map

Case data by zipcode aggregate

The size of the blue circles is proportional to the number of cases in that zip code area.
