Each year Esri brings people together from all over the world who share a common interest - to make the world a better place through maps. This year’s Esri User Conference gathered over 16,000 participants in San Diego, California, including 14 representatives from the CGIAR Consortium for Spatial Information (CGIAR-CSI) and HarvestChoice. Participants shared their stories of where with the help of technological innovation in digital mapping, big data, remote sensing, and GIS.

The June 2012 issue of Insights, IFPRI’s quarterly magazine, talks up HarvestChoice’s increasingly popular online tool: MAPPR. So friendly to use that a writer and a graphics designer combined wits to create the MAPPR-generated visuals for the article.

Fueled by a commitment to help society, agriculture is on Esri's mind. In fact, the World Bank asked them to write about it for FARMD: The Forum for Agricultural Risk Management in Development. And what did Esri –The global leader in Geographic Information System (GIS) software and geodatabase management applications – write about? HarvestChoice!

Whether you work directly with spatial data or simply reap the benefits by tapping into mapped data products, you’ve probably heard of Esri.

HarvestChoice uses a so-called meso-scale spatial grid typically at 10km or 5-arc minute resolution.

HarvestChoice uses ESRI ArcGIS Server as a web-based spatial data sharing/exploration platform. This post presents a quick example application using Port Sheds dataset.

Many of HarvestChoice’s spatial analyses are done using raster datasets at various spatial resolutions (e.g., 1 km, 10 km, or 50 km grids).

The travel time maps indicate the degree of accessibility from a pixel to a populated place. The patterns shown here describe the geographic accessibility between places in Sub-Saharan Africa. We define accessibility as the time in hours required to travel from a given single point (1x1km pixel) to the nearest market center. Travel time to market centers is used as a proxy for market accessibility and shows the likely extent to which farming households are physically integrated with or isolated from markets.

To facilitate the exchange of HarvestChoice-developed datasets and analysis results with broader geospatial community, a standard/systematic global grid database was developed for multiple spatial resolutions (from 1 degree to 30 arc-second). The new grid database, called HCID, can be used as a key identifier that links and harmonizes various themes of raster datasets as well as aggregates them even at multiple resolutions. This can be helpful not only for GIS analysts but also for researchers who would need to handle the datasets in relational database management systems.
