Land cover Mapping in Data Scarce Environments: Challenges and Opportunities. Another paper on Land Cover

Land cover maps are a critical component to make informed policy, development, planning, and resource management decisions. However, technical, capacity and institutional challenges inhibit the creation of consistent and relevant land cover maps for use in developing regions. Many developing regions lack coordinated capacity, infrastructure, and technologies to produce a robust land cover monitoring system … CONTINUE READING

Primitives as building blocks for constructing landcover maps – New paper out on RLCMS and Google Earth Engine

Land cover maps play an integral role in environmental management. However, countries and institutes encounter many challenges with producing timely, efficient, and temporally harmonized updates to their land cover maps. To address these issues we present a modular Regional Land Cover Monitoring System (RLCMS) architecture that is easily customized to create land cover products using … CONTINUE READING

Validation of a cadastral map created using satellite imagery and automated feature extraction techniques: A case of Nepal

Estimates suggest that only 30 percent of the world’s population has access to formal land administration systems to register and protect their land rights. Surveying and mapping cadastral boundaries using traditional, field-based methods is accurate but can prove to be extremely time, cost and labor-intensive. This makes it difficult to create or update existing cadastral … CONTINUE READING

Intricacies of implementing an ITU-T X.1303 Cross-Agency Situational-Awareness Platform in Maldives, Myanmar, and the Philippines

Maldives, Myanmar, and the Philippines are vulnerable to natural disasters. Sendai Framework of Action calls for risk reduction by implementing early warning systems. A prevailing challenge is for authorities to coordinate warnings across disparate communication systems and autonomous organizations. Cross-Agency Situational-Awareness platforms and the ITU-T X.1303 Common Alerting Protocol (CAP) interoperable data standards present themselves … CONTINUE READING

An Operational Before-After-Control-Impact (BACI) Designed Platform for Vegetation Monitoring at Planetary Scale

In this study, we develop a vegetation monitoring framework which is applicable at a planetary scale and is based on the BACI (Before-After, Control-Impact) design. This approach utilizes Google Earth Engine, a state-of-the-art cloud computing platform. A web-based application for users named EcoDash was developed. EcoDash maps vegetation using Enhanced Vegetation Index(EVI) from Moderate Resolution … CONTINUE READING

Annual continuous fields of woody vegetation structure in the Lower Mekong region from 2000‐2017 Landsat time-series – A paper with GLAD at UMD

As a SERVIR-Mekong, we have been working closely with our Applied Science Team (AST)  at The Global Land Analysis and Discovery (GLAD) laboratory in the Department of Geographical Sciences at the University of Maryland led by Dr. Peter Potapov. The annual product on the Tree Cover Canopy (TCC), Tree Cover Height (TCH) and Primary Forest … CONTINUE READING
