Article
Full-text available
Caribbean small island territories are heavily dependent on coastal infrastructure and growth of economies is dependent on further development. Planning for new investment in the coastal zone requires accurate topographic data for flood hazard assessment, protection of coastal resources and ensuring sustainable development. Within this research, un...
Article
Full-text available
Vertical separation models are valuable for coastal zone management and protection against the effects of climate change. To date, the development of such models has been undertaken in areas where long term sea level measurements exist and there are resources for extensive offshore bathymetric and GNSS surveys. Many small island developing states a...
Chapter
This work addresses the 3D character of marine spaces and proposes the application of the Land Administration Domain Model (LADM conceptual standard ISO 19152) to specific jurisdictional MAS or MC, taking into account the S-121 Maritime Limits and Boundaries (MLB) Standard, which refers to LADM. Several modifications are proposed, including e.g., t...

Developing and implementing strategies to achieve, monitor, and measure progress toward the Sustainable Development Goals (SDGs) requires robust and functional national geospatial data ecosystems (NGDE). However, most countries in the Caribbean region are yet to achieve a high level of geospatial data ecosystem readiness. Several factors account fo...
Article
Full-text available
The interests, responsibilities and opportunities of states to provide infrastructure and resource management are not limited to their land territory but extend to marine areas as well. So far, although the theoretical structure of a Marine Administration System (MAS) is based on the management needs of the various countries, the marine terms have...
Chapter
In the last few decades in particular, Trinidad and Tobago has suffered a perennial flooding problem. Extensive physical development in most of the watersheds of the country has led to extensive flooding in low-lying areas. The problem is exacerbated when the tides are high during periods of heavy rainfall since the flood waters are prevented from...
Conference Paper
Full-text available
The use of Unmanned Aerial Vehicles (UAVs) in civilian applications has increased greatly over the last few years. Especially for small area coverage, such a system has the advantages of being more flexible, rapid, efficient, and weather independent when compared to standard airborne aerial surveys. Of high interest is their application in the acqu...
Conference Paper
Full-text available
The Caribbean region lies between North and South America and encompasses the Caribbean Sea, the countries from as far south as Guyana to as far north as Bahamas and the adjacent coasts. The region comprises more than 7,000 islands, islets, reefs, and cays and has a population that exceeds 230 million. The Caribbean Sea is approximately 90 percent...
Conference Paper
Full-text available
Coastal areas in the Caribbean have a high population density which is anticipated to increase in the future. For many of the islands, the coastal zone represents a high economic activity, as tourism based economies are predominant in the Caribbean. Historically and in recent times, coastal hazards such as hurricanes, tropical storms, tsunamis and...
Conference Paper
Full-text available
The Caribbean region is vulnerable to natural disasters as reflected by the frequent exposure to flooding, hurricanes, and earthquakes. The ability of Caribbean island-states to react effectively to such natural events is particularly low due to their small economies and geographic size. This, in turn, impacts negatively on the accessibility to cur...
Article
Full-text available
SUMMARY Traditional methods of Sea Level Rise (SLR) determination in the Caribbean have been plagued with problems of currency and availability of data to establish reliable regional models. Since most of the operational tide gauges used are in the northern Caribbean and the southern Florida coastline, the studies were focused on areas in the north...
