Accuracy for All


Accuracy for All: Community Land Mapping and the Navigation Satellite Revolution

Join us tomorrow, December 5th 2018 at 12:30PM Eastern Standard Time for a panel discussion on the democratization of property surveying through the developing world. Thanks to advances in technology and the ever improving accuracy of satellite navigation in mobile devices, more people are able to have their land mapped (or map it themselves) at an affordable level. Join Walter Volkmann and other panelists for an in depth conversation on the advent of high-accuracy GNSS technology and the effect it is having on community land mapping projects around the globe.

The rapidly improving accuracy of satellite navigation in mobile devices can help to democratize land surveying throughout the developing world. How can field practitioners best utilize this tech to implement community mapping initiatives and formalize property rights?

Across the developing world nearly a billion people live without legal title to their land. In order to formalize this property, governments need to issue titles and create secure registries in which to record them. Mapping informal land at scale, and especially delineating one person’s property from another’s is a serious technical challenge.

This challenge is all but insurmountable if approached with conventional methods. Professional surveying is prohibitively expensive in much of the developing world, and there are not enough licensed surveyors to do the work. Recent advances in global navigation satellite system (GNSS) technology have weakened the correlation between precision and cost, promising to make survey-grade accuracy widely available in smartphones.

With widespread access to high-accuracy location data, some of the most time-consuming and expensive parts of the formalization process can be completed more quickly and cheaply at the local level. Yet collecting geospatial data is only half the challenge. Land registration also requires the gathering of information about the people living on the land. This data must be collected in a way that respects cultural sensitivities and land use practice, as well as the privacy of landholders. Taken together, these two components constitute the basis for a community land mapping initiative.

Please join the Future of Property Rights Program for an in-depth conversation on the advent of high-accuracy GNSS technology in mobile devices and its significance for community land mapping projects in the developing world.
