Hyperspectral and colorimetric patterns were determined from anatomical and physical aspects for the characterization of Peltogyne dry wood Pittier purpurea, from trees of natural forest.
The objective of the research is to generate the urban sprawl of cities Central American capitals of the years of study through a methodology with remote sensing and the implementation of various techniques for processing and post-processing of Landsat satellite images; in addition, techniques were used in photointerpretation, classification and digitization with Information Systems Geographic (GIS).

The article describes the contributions and challenges of the PRIAS Laboratory in the fields of geomatics and Earth observation. It includes a review and systematization of historical data from the beginning of PRIAS as a program, its transformation into a laboratory, and its progress through 2023. It was published in the proceedings of the International Astronautical Congress organized by the International Astronautical Federation 2024 at the Earth Observation Symposium.
It describes the use of Earth Observations in the MOCUPP project and the impact on land use change management in productive landscapes. It was published in the proceedings of the International Astronautical Congress organized by the International Astronautical Federation 2024 at the Earth Observation Symposium.
The article presents the initiative of the PRIAS Laboratory's computational creative space for outreach and education in the field of Earth observation, which was published in the proceedings of the International Astronautical Congress organized by the International Astronautical Federation 2024 at the Space Education and Outreach Symposium.
Inappropriate or excessive use of fertilizers mobilizes excess nitrate ions into surface and groundwater through runoff and percolation processes. The impact is a deterioration of ecosystems and water quality. In this research, the concentration of nitrate ions in the surface waters of a territory was modeled under the same land use model, Costa Rica, with 88.2% accuracy. Free access physicochemical data and geographic information were used in the modeling, processed with the Random Forest learn
Final report on the results of the Monitoring of Change in Use of Productive Landscapes (MOCUPP) Project, led by the PRIAS Laboratory, CeNAT CONARE
Introduction: Until today, the fishing effort by foreign fleets in the Costa Rican Pacific has not been analyzed. Objective: To determine the spatial distribution of their fishing effort, variables that shape that distribution, and if those fleets interact with management figures and highly fragile ecosystems. Methods: Using fishing effort data from 2012 to 2020, obtained from Global Fishing Watch, an Index of Fishing Effort (IEP) was calculated to apply geospatial and multivariate statistics, a
Modeling of chlorophyll-a with satellite data can be achieved by finding a best fit function between spectral bands of reflectance related to its concentration. Google Earth Engine (GEE) is a platform designed for the processing of multispectral satellite databases used for the temporary observation of terrestrial phenomena. This tool was selected to model the chlorophyll-a concentration of the Sierpe River, which is located within the Térraba Sierpe National Wetland (HNTS), Costa Rica. For the
