03-03: Low-cost ways to establish cadastral systems
Precision geolocation at the service of least developed countries
GNSS is a technology that enables location of objects, points and maps anywhere in the world with the same level of accuracy. In particular, it allows emerging countries to set up internal databases in perfect complementarity and continuity with international information.
In France, the “Ordre des Géomètres-Experts” launched the TERIA project in 2005 to deploy a network able to offer an NRTK satellite data processing service with centimetric accuracy. This network served as a basis for the deployment of the Géo-Foncier digital portal, which is today the keystone of the management of land rights and public constraints.
The TERIA process can be replicated in least developed countries and participate in their autonomy. It is a powerful lever for setting agricultural policies and boosting the global economy by offering a leading basic tool for advanced technologies (robotics, navigation, transport ...).
Fit for Purpose, scalable GNSS data collection
Leica Geosystems, Germany
It is not uncommon for the user of a software or hardware product to touch only a small percentage of the tools available to them. Functionality correlates highly with cost and can be a contributing factor to users being excluded from innovative new technology. GNSS data collection vendors have a responsibility to ensure their products are not only fit for purpose but also flexible enough to reach a wide range of users.
Scalability has become an expectation of the user and you no longer have to be locked into a large, complex workflow when you can pick and choose which elements of a system are relevant for you. Software and hardware should align to user’s needs as their own industries are developing and changing as rapidly as the technology is advancing. Users need a solution which is tailored to their knowledge and experience. This is especially important for developing countries.
Customized earth observation based information services
1GeoCodis Ltd., Slovenia; 2ZRC SAZU, Slovenia
Earth observation (EO) data enables a quick assessment of regions of interest. This is particularly relevant for areas undergoing social and economic change that may lead to increased pressures on natural resources. The present work focuses on the development of a cloud-based end-to-end processing chain which provides easy-to-use services for rapid overviews of on-the-ground conditions. The resulting EO-based information including maps, time series graphs and derived statistics can be integrated into geospatial systems or reports.
Using Sentinel-1 and Sentinel-2 data, and customized generic modular workflows to provide Information Layers (IL), the product is designed to assist monitoring and safeguarding actions by International Development Banks.
Broader areas of interest are arid zones, where there have been conflicts, big population changes, and/or urban expansion. Four thematic IL are conceived: Extent and status of dwellings of forcibly displaced persons, Surface water extent, Grassland extent and status, and Degradation risk assessment.
Deploying titling and customary land registration systems with a blockchain element
Medici Land Governance, United States of America
Medici Land Governance, working with communities and governments, has written systems to gather ownership claims and also to register titles with governments. We describe the work in Zambia for a systematic titling project, which includes features for transparency using a public blockchain network. We then describe an approach that applies to customary land, where the communities are able to assert their ownership and later verify their claims on a public blockchain in a semi-public way; this approach requires smart-phones and thus currently applies to areas outside Africa (eg. Peru), but it allows for independent affirmations. We will discuss the designs and tradeoffs for these systems, mostly from an engineering point-of-view but including lessons learned in policy and logistics.
