Los datos de uso de la tierra fueron obtenidos mediante evaluación visual multitemporal (EVM) de puntos de muestreo utilizando imágenes satelitales de alta resolución a través de Collect Earth. Las estimaciones de áreas de cambio de uso se realizaron según categorías generales de cambio, y según las actividades específicas de REDD+, además de evaluar distintos tipos de estratificaciones. Se demostró que es posible hacer las estimaciones de datos de actividad requeridas para el MRV de REDD+ CR a partir de Collect Earth, sin embargo, es necesario intensificar el muestreo en las áreas de interés para reducir las incertidumbres, y mejorar la disponibilidad de imágenes de alta resolución en Collect earth para disminuir la cantidad de puntos clasificados como &#8220;sin información&#8221;.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract This study examines the capacity of the software Collect Earth to generate activity data as required by Costa Rica&#8217;s REDD+ program. Thereby, estimations of land use changes for the 2014-2015 period were made according to the Costa Rica&#8217;s REDD+ monitoring, reporting and verification (MRV) system. Land use data was obtained through multitemporal visual interpretation of sampling points using high resolution satellite imagery via Collect Earth. Estimations of areas of change were made in accordance with general REDD+ land use change categories and REDD+ CR activity classes. Evaluation of two different types of stratifications were also made. The study demonstrates that it is possible to estimate activity data following the REDD+ CR MRV system using Collect Earth. However, it is necessary to intensify the sampling in areas of interest in order to reduce uncertainties, as well as to increase accessibility the high resolution imagery in Collect Earth to decrease the number of sample points without data.]]></p></abstract>
