Tanto los Sistemas de Información Geográfica como la Recuperación de Información han sido campos de investigación muy importantes en las últimas décadas. Recientemente, un nuevo campo de investigación llamado Recuperación de Información Geográfica ha surgido fruto de la confluencia de estos dos campos. El objetivo principal de este campo es definir estructuras de indexación y técnicas para almacenar y recuperar documentos de manera eficiente empleando tanto las referencias textuales como las referencias geográficas contenidas en el texto. En este artículo presentamos la arquitectura de un sistema para recuperación de información geográfica y definimos el flujo de trabajo para la extracción de las referencias geográficas de los documentos. Presentamos además una nueva estructura de indexación que combina un índice invertido, un índice espacial y una ontología. Esta estructura mejora las capacidades de consulta de otras propuestas

ka-Map ("ka" as in ka-boom!) is an open source project that is aimed at providing a javascript API for developing highly interactive web-mapping interfaces using features available in modern web browsers. ka-Map currently has a number of interesting features. It sports the usual array of user interface elements such as: interactive, continuous panning without reloading the page; keyboard navigation options (zooming, panning); zooming to pre-set scales; interactive scalebar, legend and keymap support; optional layer control on client side; server side tile caching

Process supervision is the activity focused on monitoring the process operation in order to deduce conditions to maintain the normality including when faults are present Depending on the number/distribution/heterogeneity of variables, behaviour situations, sub-processes, etc. from processes, human operators and engineers do not easily manipulate the information. This leads to the necessity of automation of supervision activities. Nevertheless, the difficulty to deal with the information complicates the design and development of software applications. We present an approach called "integrated supervision systems". It proposes multiple supervisors coordination to supervise multiple sub-processes whose interactions permit one to supervise the global process

Shape complexity has recently received attention from different fields, such as computer vision and psychology. In this paper, integral geometry and information theory tools are applied to quantify the shape complexity from two different perspectives: from the inside of the object, we evaluate its degree of structure or correlation between its surfaces (inner complexity), and from the outside, we compute its degree of interaction with the circumscribing sphere (outer complexity). Our shape complexity measures are based on the following two facts: uniformly distributed global lines crossing an object define a continuous information channel and the continuous mutual information of this channel is independent of the object discretisation and invariant to translations, rotations, and changes of scale. The measures introduced in this paper can be potentially used as shape descriptors for object recognition, image retrieval, object localisation, tumour analysis, and protein docking, among others
