APHEO GIS Interest Group

Why did you Join? 86% -- General 46% -- New analytical methods 32% -- Core indicator development 73% -- Promoting the use of GIS in

public health 54% -- Access GIS support

APHEO GIS Interest Group Focus

Standardizing processes so that there is the ability to compare between PHU's, LHINs, etc.

Establishing a basis level of proficiency in each organization Coordinate educational sessions to increase awareness,

knowledge and use of GIS in public health units Putting together some sort of resource list for members to

access Analysis issues Skills development Development of spatial indicators Develoment of an inventory of what has been done Sharing of templates/worksheets that can be used by others Exploring potential for advanced spatial analysis Immediate and long-term training needs Methods of expanding the use of GIS in public health

APHEO GIS Interest Group Ideas for education topics

Demonstration of ArcView Basic cartography Basic spatial data handling - creating geospatial databases Software for statistical approaches Geocoding , address cleaning, standardization Available data sources and what you can do with them Case studies - use of GIS in public health (local, relevant topics) Learning about/how to incorporate enhanced graphics Advanced GIS tips and tools Interactive mapping tools for on-line mapping Cluster analysis and spatial statistics Potential uses of GIS in infectious diseases surveillance given

limitations of low numbers and limited resource Interfaces with other software Time series and trend analysis using GIS
