Basic concepts

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

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
![Page 7: Making HIV-related maps in minutes: " Indiemapper " - free mapping tool for everyone](https://reader033.fdocuments.us/reader033/viewer/2022042822/56813b91550346895da4c0fc/html5/thumbnails/7.jpg)
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?
![Page 10: Making HIV-related maps in minutes: " Indiemapper " - free mapping tool for everyone](https://reader033.fdocuments.us/reader033/viewer/2022042822/56813b91550346895da4c0fc/html5/thumbnails/10.jpg)
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 responsesWhere 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
![Page 15: Making HIV-related maps in minutes: " Indiemapper " - free mapping tool for everyone](https://reader033.fdocuments.us/reader033/viewer/2022042822/56813b91550346895da4c0fc/html5/thumbnails/15.jpg)
Mapping software (1)
• General:
ArcGIS, GeoCommons, Target Map, CartoDB, Quantum GIS, MapBox, OpenHeatMap, Google Earth
The most commonly used GIS software usually cost $1500 per
user license!
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
