Abstract
In this paper we present the interim results and the methodology applied to create web GIS ready cartographic representations of agricultural performance related information and environmental parameters. The main aim of the research is to eventually create a web GIS based decision support system that can enable decsision makers and general users to create useful and representative map layouts of certain environment and agriculture related phenomena that can be easily analyzed and interpreted to make strategic decisions on environmental issues. In this aim the initial steps are to evaluate the available data for cartographic representation, analyze the possibilities of visualization, create a GIS ready data structure and implement the database and revise additional possibilities to incorporate further environment related datasets of auxiliary sources. The main results of the study are a comprehensive set of visual layouts that could serve as guideline for mapping statistical information of agriculture and some steps towards the incorporation of environmental parameters to the system.
Highlights
Decision support systems are widely used in analysis and interpretation of environment and agriculture related processes and phenomena (Papamichail and French, 2005)
In environmental and earth sciences with the penetration of Geographic Information Systems (Herrero-Jiméne, 2012) it became possible to analyze certain phenomena in the spatial domain. This can lead more accurate decisions over environmental issues and allows the incorporation of spatially distributed information to be treated in its domain. This exceptional feature of GIS systems enable to build very specific GIS systems that serve as decision support system tool by combining the descriptive multivariate attribute variables with exact location in the spatial domain as in (Wanmei Ou et al, 2010)
In this study we introduce the initialization of such spatially enabled decision support system (Seffino et al, 1999) to address issues arising in agricultural production and environmental treatments in the same time
Summary
In this paper we present the interim results and the methodology applied to create web GIS ready cartographic representations of agricultural performance related information and environmental parameters. For the purpose of agricultural analysis we use standard agricultural performance related datasets (Briassoulis, 2007) combined with traditional statistical information that is collected and stored in a non optimized manner for spatial representation and modeling During this initial phase of the research elementary steps were defined to build the geospatial database, establish a way to convert the non-spatial datasets to geodata by geocoding them, and a number of visual representations were created to assess the best way of presenting users with the data. Such indices are the D'Hort index (Cox, 1991) or index of large heads per capital
