    Aplicación de los SIG para la evaluación del estado de conservación del hábitat del Paujil De Pico Azul Crax Alberti (Aves: Cracidae) en el Nororiente de Antioquia, Colombia
    (2014-05-07) Molina-Giraldo, A. M. (Adriana María); Barros-Martínez, J. F. (Juan Fernando)
    The blue-billed curassow, Crax alberti, is a critically endangered endemic bird from the northern part of Colombia, mainly subjected to habitat loss and subsistence hunting. Geographic Information Systems (GIS) were used to compare the conservation status of forested areas, habitat of the blue-billed curassow, in 15 municipalities of the northeastern region of Antioquia for two different time periods (1986 and 2002). The developed application using digital cartography, allowed the classification of eight zones defined for the study area in order to analyze conservation priorities. Recommendations are made as well for future applications of GIS as a management tool for threatened species in Colombia.

    Definición de un método basado en patrones de análisis para la interoperabilidad entre sistemas de información geográfica
    (2013-11-08) Zapata, Carlos Mario; Toro B, Francisco M. (Francisco Mauricio); Marín, María Isabel
    Geographic Information Systems (GIS) are incorporated in the companies to facilitate spatial analysis of the information. This analysis often requires the integration of GIS heterogeneous data to interoperate. In GIS, interoperability is mainly addressed by the specification of standards and the implementation of several mechanisms like ontologies, web services, grid computing, and middleware technologies. In order to implement any of such mechanisms, an analyst should make a detailed and iterative study of the GIS domain for every situation of interoperability is needed. Such study is, commonly, subjective and highly dependent on the analyst experience. Consequently, the entire process seems not to be transparent and traceable. For this reason, in this paper we propose an interoperability method for generalizing the analysis phase of the GIS domain. The method comprises seven steps supported by analysis patterns expressed in pre-conceptual schemas. The method can be integrated with the aforementioned mechanisms for interoperability, thus shortening the analysis phase and providing a communication channel between the user, the analyst, and the developer.

    Proyecto de observatorio de turismo para Medellín y Antioquia
    (2014-05-15) López-Zapata, L. (Ledys); Márquez-Godoy, J. I. (Jose Ignacio)
    The sectorial work require to feed the economic and social forces with updated and reliable information to orient the focus and making of decisions. The observatories, which work like information management centers, are a proposal that keep the consolidation the efforts inside of organizations from the public-private order that guarantee the sector development. In the text are presented functions, organizational structure, reports, services and the way to do the things which have to take into account organizations like the observatory to satisfy the regional and local needs that can have in the tourism sector.

    Los Sistemas de Información Geográfica (SIG) en la planificación municipal
    (2014-05-07) Molina-Giraldo, A. M. (Adriana María); López, L. F. (Luis Fernando); Villegas, G. I. (Gloria Isabel)
    A review of the experiences with GIS technology that different municipalities and governmental institutions in the Oriente Antioqueño and Valle de Aburrá regions have had is presented here, identifying conditions that have made its appropriation in a daily basis easier or more difficult. The advantages of GIS technology are shown here from a simple perspective, achievable practically by any municipality or governmental institution. Based on the experiences of municipalities that for several years have been in the process of using this tool, it is shown how general data that are daily obtained can be easily organized, analyzed, and visualized for decision making in planning helped by GIS technology, starting from simple systems, and making them stronger as experience and familiarity with the technology is gained. The most used GIS software and functions in Colombia are presented, as well as a description of the problem of reliable data availability and interaction between governmental institutions, since this is considered a chief condition for consistent planning processes.
