  1. M&E of Programs and the Data Infrastructure: GIS as the Rosetta Stone John Spencer MEASURE Evaluation

  2. MEASURE Evaluation is funded by the U.S. Agency for International Development (USAID) through Cooperative Agreement GPO-A-00-03-00003-00 and is implemented by the Carolina Population Center at the University of North Carolina in partnership with Constella Futures International, John Snow, Inc., ORC Macro International, and Tulane University.

  3. Data

  4. Where?

  5. Why?

  6. Value of Mapping • Provides insight into data • Provides a way to link different data • Strengthens data infrastructure by enforcing data schema standards • Picture worth 1,000 words

  7. GIS

  8. World in Layers

  9. Value of Geography • Maps can be • Decision support tools • Analysis tools • Data display tools • More than just mapping

  10. Geography Can Strengthen The Data Infrastructure

  11. Data Infrastructure • Available data • Systems to support, update and disseminate data

  12. OVC ART PMTCT PublicHealth Data

  13. GIS as Rosetta Stone • GIS can be a “Rosetta Stone” to link different data sets • Produces maps showing linkages that may not have been made before • STRONGER DATA

  14. Geography is key link Population OVC

  15. Geography is key link Population and OVC

  16. Geography is key link • Seems obvious • Data needs to have a geographic identifier • Data must have complimentary structure • Don’t necessarily need a GIS – can be done in Access or Excel

  17. Geographic Identifiers -0.125312 S 34.754180 E -0.125140 S 34.754213 E

  18. Geographic Identifiers • Administrative units • Districts • Province • Ward • Etc. • Village or community name

  19. Nigeria OVC Case Study

  20. One Tool In the Toolbox

  21. Key Steps Implementing GIS • Include Geographic Identifier in Data • Where are things? • Software • ArcGIS • Google Earth

  22. Summary • Adding the “where” can help understand the “why” • Geography can act as a “Rosetta Stone” to link different elements of the data infrastructure • GIS/mapping can strengthen data quality by enforcing data schema standards

  23. Excel and Google Earth Mapping for the Rest of us

  24. Mapping Challenges • Data • Must be well formed and have a geographic identifier • Software

  25. Three shelves of ESRI Manuals and third party materials

  26. Excel to Google Earth Macro • MEASURE Evaluation developed tool that allows Excel data to be mapped in Google Earth

  27. Target Audience • Decision makers • Data and M&E staff • Anyone with Excel data they’d like to map

  28. Not a GIS • Data display tool only • Doesn’t do spatial analysis • Buffering, density estimation, spatial stats, etc. • Can’t manage layers Its niche is: a quick, easy to use tool
