In this paper, we evaluate eleven image descriptors for urban-rural classification using aerial images. The eleven image descriptors are composed by seven texture-based descriptors and four combinations of texture and color descriptors. The classification is carried out using Support Vector Machine (SVM) with radial basis function as kernel function. The performance of these images descriptors are...

Continuous monitoring of physical parameters such as soil moisture is crucial to improve food sustainability and risks mitigation. To estimate soil moisture, there are direct and nodirect measurement methodologies; each of these ones has its own advantages and disadvantages. Therefore, no-direct measurement methodologies have the ability to get wide spatial coverage of inaccessible places than other...
Remote sensing methods for the understanding of physical phenomena has been used since the last 50 years. Satellitebased sensors and ground-based sun photometers provide quantitative and qualitative knowledge about the composition of different elements that exists within the atmosphere of the Earth. One of the current tasks relates to understanding the changes of the climate on different regions throughout...
Geomatics offers answers to socioenvironmental problems through the use of technological tools and methodologies linked to spatial analysis and representation. There is a high demand in the labor market of highly competent human capital to solve this type of problems and to influence on decision making. The aim of this work is to highlight the advantages that a Diploma program in Geomatics by competencies...
Land surface evapotranspiration (ET) data is required accurately and in near-real time for operational applications such as regional drought monitoring. Satellitederived ET data products are promising for this purpose, particularly for poorly gauged areas such as south-eastern Mexico. Products (and algorithms) such as MODIS Global Evaporation Project (MOD16) are readily and publicly available but...
Currently, Mexico City is facing a growing concern about the production and treatment of urban waste (RSU of its acronym in Spanish), also known as municipal solid waste (MSW), due to the lack of long-term planning and because many landfills (RESA in Spanish) have exceeded their capacity. In addition, finding new sites for landfilling waste is difficult because many studies and analyses from specialists...
Radiometry of earth’s gravity (gravity gradiometry) and gravimetry have become key tools to perform reconstructions of geological strata in the upper earth’s crumble. In several locations, it is being intensely used to locate unknown oil reservoirs by determining the gravity anomalies produced by salt bodies. Nevertheless, in most cases, gradiometric or gravimetric data are obtained by ships or airplanes,...
In this paper, we report the main functionality of the Mexican ground station for receiving satellite information (ERIS), located in the facilities of the research public center El Colegio de la Frontera Sur, Unidad Chetumal. In this year, after a period of inoperability, 2013-2015, under a new national consortium, the ground station will be fully operating at the end of the year. Thus, details about...
The system presented in this paper is capable of extract information about cities in Mexico. These cities or objective areas are identified using a spatial database and open data from the National Institute of Statistics and Geography (INEGI). The aim of this first version is to establish a data flow and process optimized in computational resources, quickly expandable in remote sensing algorithms...
The objectives of this work were to identify areas in probability of being deforested in the west of Chihuahua, Mexico, and their causal variables, using a logistic regression model. The work was developed in a Geographic Information System, through the deployment and statistical regression between ten layers of geographic information (biophysical and socioeconomic) related to deforestation and deforested...
The objective of this research was to determine the relationship between the inefficiency of furrow irrigation, the geometric characteristics of agricultural plots and the depletion of the aquifer of the Laguna Bustillos basin (Chihuahua, Mexico) in recent decades (1991-2012). The main results were: i) the analysis of geometric characteristics showed that the Mennonite properties have the least favorable...
