Making HIV-related maps in minutes: "Indiemapper" - free mapping tool for everyone AIDS-2014 Workshop, 24/07/2014, Melbourne, Australia Yuliia Sereda, PhD Institute for Economics and Forecasting, NAS, Ukraine

Objectives Basic concepts, reasoning and software Indiemapper tools Practical exercise “ HIV prevalence and affected populations in Europe ” Questions and answers

Basic concepts

What is map? A graphic representation of spatial concepts, where some real characteristics of geographical regions are replaced with symbols Photo credit: UNICEF Ukraine

Historical note The first known world map was made in 2300 century BC Babylonians (modern Iraq) on a clay tablet

Geographical Information Systems (GIS) Type of software Tool-kit Approach to deal with spatial data

Data Attribute data – what a feature is Nominal data – names or of objects Categorical data – separates data into groups or classes Ordinal data – separates data based on quantitative rank Numerical data – data based on numbers with a standard interval between them Spatial data – where the feature is (co-ordinate based data)

Layers Data on different themes are stored in separate “layers” Layers from different sources can be integrated using location Complex maps of HIV/AIDS related subjects from widely disparate sources

Why do we need maps?

Comprehensible format to multiple audiences Estimated prevalence of HIV among young adults (15-49) in Africa (2005, UNAIDS)

John Snow (London, 1854) Certain diseases tend to occur in some places and not others Spatial relations

Map for responses  Where are the transmission main spots?  Where are the prevention services?  Are the right services in the right places?  Do we have adequate coverage? Needs assessment, program planning and evaluation

Spatial distribution of disease Mapping populations at risk Trends, both temporal and spatial Input, process, output and outcome evaluation Planning and targeting interventions Maps for HIV/AIDS

GIS software

Mapping software (1) General: ArcGIS, GeoCommons, Target Map, CartoDB, Quantum GIS, MapBox, OpenHeatMap, Google Earth License, registration, extensive analytical capabilities

Mapping software (1) HIV-related tools: STATmapper - interactive maps from 54 surveys in 46 countries. Topics include HIV indicators. HIVmapper - maps based on standard HIV indicators from surveys in over 20 countries HIV Spatial Data Repository – HIV-related data for 49 countries AIDSvu - AIDS information for the USA on a map Limited number of countries and indicators, non-targeted to specific project
