The abstract should appear at the top of the left-hand column Crop yield estimation are topics of interest in Latin-American countries, for farmers and government officers responsible of managing agricultural national policies. Besides, modern remote sensing methodologies to obtain these predictions represent important steps towards attaining the goals of precision agriculture for the 21st century...
This work was realized in the state of Guerrero, Mexico considered a high marginalization region in the country. The aim of this work was to generate the agricultural frontier and to determine the spatial distribution of maize and beans from satellite images using two classification algorithms. Of the entire state area (6,357, 781 hectares), 15.6% is occupied by agriculture. Of this, 244,585 hectares...
Aquaculture has an important potential in the alleviation of food shortfalls and poverty in many countries. The effective practice of aquaculture is based on several requirements, among which the location of appropriate sites and information which allows merging with activities of local populations are important. This paper reports on the location of appropriate water bodies for inland aquaculture...
The paper analyzes the problem of achieving a coherent operation in Geostationary SAR (GEOSAR) missions intended for continuous monitoring of land surfaces. In contrast to LEOSAR missions, GEOSAR uses very long SAR integration times (from minutes to hours). Accordingly phase errors due to orbit perturbations, radar master oscillator drift, atmosphere propagation and other sources must be conveniently...
Geospatial database items originate from the analysis of images and from the manipulation of geographic data. The corresponding datasets are described via diverse structures of metadata. GeoBase L9 is a project whose aim is to build a geospatial database to support geomatics research in agricultural and natural resource management. The first objective, to support basic browsing access to datasets,...
In central Mexico, specifically in the State of Mexico maize is cultivated under different technological regimes ranging from traditional rain water dependency and native seeds producing yields of under 1.0 ton/ha, up to irrigation and improved seeds regimes with yields above 12.0 ton/ha. The average state yield harvested area for this crop in the past 10 years has been 549, 000 ha with an average...
This paper identifies a dynamic cross-layer architecture for QoS provisioning of multimedia services on an all-IP-based DVB-RCS/S2 satellite network. The proposed dynamic QoS architecture presents three cross-layer interfaces: one between the application and network layers on the satellite terminals (ST), which allows the provision of dynamic guaranteed QoS for multimedia applications and the user...
