摘要 加勒比地区容易遭受自然灾害，频繁遭受洪水、飓风和地震就表明了这一点。由于经济规模和地理面积较小，加勒比岛国对此类自然事件做出有效反应的能力特别低。这反过来又会对获取当前准确的空间信息产生负面影响，而这对于相关机构有效应对危机至关重要。航空摄影测量的创新使其成为捕捉和评估自然灾害造成的损害程度和数量的宝贵工具。然而，由于用于测绘的公制相机和飞机成本高昂，因此有必要研究小岛屿发展中国家负担得起的其他替代系统。对于小区域覆盖，与标准机载航空测量相比，这种系统具有更灵活、快速、高效且不受天气影响的其他优点。本文对与低成本相机和获取航空照片的平台相关的技术进行了概述和评估。考虑到加勒比热带小发展中岛屿的成本因素和业务性质，本文建议采用无人机（UAV），因为它们是灾害测绘和管理活动中其他测绘系统的可行替代解决方案。最后，本文提出了考虑合适系统的某些标准。
SUMMARY 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 current and accurate spatial information that is critical for the effective response to a crisis by the relevant agencies. Innovations in aerial photogrammetry have allowed it to become a valuable tool in capturing and assessing the extents and amount of damages due to a natural disaster. However, due to the high cost of metric cameras and aircraft for mapping, it is imperative to examine other alternative systems affordable for the small island developing states. For small area coverage, such a system would have the other advantages of being more flexible, rapid, efficient, and weather independent when compared to standard airborne aerial surveys. This paper presents an overview and assessment of the technology relevant to low cost cameras and platforms to acquire aerial photographs. Considering the cost factors and the operational nature in the tropical small developing islands of the Caribbean, the paper recommends adopting unmanned aerial vehicles (UAV) as they represent a viable alternative solution over other mapping systems for disaster mapping and management activities. Finally, the paper presents certain criteria for considering a suitable system.
