Being an ontologically multidisciplinary topic, language change is among the best candidates to be addressed using Geographic Information Systems (GIS). GIS can integrate datasets from diverse disciplines along with real-world geographical information, hence facilitating the investigation of (i) the spatial relations existing between research items and (ii) (past) landscapes. Drawing from an ongoing project focused on the historical development of the extremely diverse linguistic situation documented in the Lower Fungom region (Northwest Cameroon), this article explores the possibility of placing authentic interdisciplinary research pivoting on linguistic issues within a GIS framework.

Resumen El ordenamiento territorial como disciplina ha venido aplicándose alrededor del mundo desde hace ya mucho tiempo; evidentemente sus procesos se han optimizado, y han evolucionado no solo técnica sino conceptualmente. Sin embargo, la velocidad a la que crecen actualmente las ciudades genera una brecha cada vez mayor con los procesos de planificación, que difícilmente pueden producir políticas o acciones urbanísticas que lleguen a tiempo a los territorios.La aparición en escena de los Sistemas de Información Geográfica ha ofrecido una nueva variedad de métodos y herramientas que en concordancia con los acelerados procesos de desarrollo urbano, han fortalecido la cultura de la planeación en la reducción de sus tiempos de análisis, la adquisición de datos y fundamentalmente en la toma de decisiones. En ese sentido, este artículo plantea la aplicabilidad de los SIG en el Ordenamiento Territorial, con base en la profunda relación existente entre los componentes básicos del primero y las metodologías de trabajo del segundo, y mediante ejemplos de algunas de las aplicaciones prácticas que se le pueden dar a esta nueva tecnología en el ámbito del urbanismo. Palabras ClavePlanificación urbana, Urbanismo, Relaciones Espaciales, Territorio. Abstract Urban planning as a discipline has been used around the world since long time ago; obviously it´s processes have improved and it has evolved not only technically but conceptually. However, the accelerated growth process of the cities is producing an every time bigger breach with the planning processes, that hardly produce on time policies or urban actions to apply on the territories. The appearance of the Geographic Information Systems has offered a new variety of methods and tools that according with the strong urban growth, has helped to improve the planning culture reducing the duration of its analyzing processes, the data acquisition, and mainly the decision making. In that order, this paper set up some of the application methods of GIS in Urban Planning, based on the deep relation that exist between the basic components of the first and the work methodologies of the second one, and using examples about some of the practical uses that may have this new technology at the urbanism field.KeywordsUrban Planning, Urbanism, Spatial Relations, Territory.

Set Up

Cameroon through its Strategy for Growth and Employment (DSCE), has set up the construction of the Yaoundé-Nsimalen highway project. As part of the assessments of its potential effects on the environment, an ESIA was carried out, according to the framework law on the management of the environment. The acquisition of housing has resulted in an '' anarchic '' installation in the urban and peri-urban area. The construction of a highway as planned overlays on these facilities and poses a problem related to the liberation of spaces previously occupied. The purpose of this study is to identify, locate and classify the impacted goods by the highway construction project through Geographic Information Systems (GIS). Our methodology consisted first, making a satellite identification of the impacted goods, then a field campaign and finally a processing of the data collected. This study was also limited to the identification of two types of property, the buildings and parcels of land. Thus, it has been possible to distinguish and locate six categories of buildings, eight categories of parcels of land defined according to the Cameroon law No. 85/009 of 04 July 1985 on the expropriation for public purpose and the terms of compensation and according to Order No. 0082 / y. 15.1 / MNUH / D of November 20, 1987 laying down the bases for calculating the market value of buildings expropriated for reasons of public utility. The result of this study shows that mapping is a very practical tool for identifying and materializing the impacts that a project may have on components of environment. The GIS revealed a potential disappearance of 1502 building spread over 867 parcels of land.

This paper considers the problem of extracting geoattributed entities from natural language texts to visualize the spatial relations of geographical objects. For visualization we use the technology of automated generation of schematic maps as subject-oriented components of geographic information systems. The paper describes the information technology that allows extracting geoattributed entities from natural language texts by combining several approaches. These are the neural network approach, the rule-based approach and the approach based on the use of lexico-syntactic patterns for the analysis of natural language texts. For data visualization we propose to use automated geocoding tools in conjunction with the capabilities of modern geographic information systems. The result of this technology is a cartogram that displays the spatial relations of the objects mentioned in the text.

‘Qualitative spatial reasoning and representation’ is a range of techniques developed in Artificial Intelligence to meet the need for a computational treatment of qualitative spatial relations. Examples of such relations include ‘next to’, ‘overlapping’, ‘to the left of’, ‘separate from’, ‘including’, and so on. These relations occur within the data found in the spatial humanities, but the computational techniques described here do not appear to have been used in connection with this context. While Geographical Information Systems (GIS) are widely used as a means of visualizing and exploring material in the spatial humanities, GIS technology is acknowledged to be ill-suited to information that is vague, uncertain, ambiguous, imprecise or having other qualities that in a scientific setting could be regarded as imperfections. In the humanities such ‘imperfections’ are of course important, and qualitative spatial relations are one source of data that challenges scientifically based GIS. This article reviews the origin of qualitative spatial reasoning and representation in A. N. Whitehead's mereotopology and argues for exploring how these methods could complement GIS as a computational technique in the humanities. Qualitative representation is applicable to modelling spatial arrangements in many domains, not just geographical space. This is demonstrated through an example of spatial relations in lines of printed text.
