    Caracterización de los manglares de Centroamérica con sensores remotos
    (Revista de Biología Tropical, 2001) Lizano, O; Amador, J; Soto, R
    Satellite images were used to study the mangrove distribution patterns in two different climatic regions of Central America: Gulf of Fonseca in Honduras-El Salvador and Sierpe-Térraba in Costa Rica. The Gulf of Fonseca has higher temperature and solar radiation, and lower precipitation, which can explain the higher structural development and species mixing of the Sierpe-Térraba mangrove. In the latter the transition between species or between heights in the same species is clear. The automatic classification made by the Geographic Information System (IDRISI) fits well the field mangrove distribution, but it was necessary to regroup some subdivisions that represent the same land use as identified by transects and an aerial video. Mixed species and clouds produced less satisfactory results in Sierpe-Térraba indicating a need for better satellite image resolution.

    Remote sensing at the Centre for Geophysical Research, University of Costa Rica
    (International Journal of Remote Sensing, 1993) Amador, J; Burgos, A; Soley, F.J.; Serpas, G; Vargas, A
    The background of the remote sensing technology in the Central American region is discussed. A brief account is given of the present state of remote sensing in Costa Rica. Although the remote sensing technology was introduced in Costa Rica and in the Central American region in the mid 1970s, it has not had a widespread use yet, specially due to economical constraints and the lack of technical and training facilities. In this respect, special attention has been given to the role of the University of Costa Rica in the transfer and application of this technology. Also, some conclusions are stated pertaining the future of remote sensing in the country.
