Based on the Belgian soil map at 1/20,000, this digital map of Wallonia (DSMW) is composed of a cartographic database describing the soil characteristics of the region. Tool for a better soil management, this database will be integrated in a geographical information system where the soil layer could be used in relation with information concerning other aspects of land development. The different operations include : map drawing finalization of non edited sheets, creation of an image layer, vectorial capture of source objects, building up of the topology, characterization of the objects, geometrical corrections, creation of a continuous layer (edge-matching), creation of a homogeneous legend, integration in a geodatabase. The DSMW in figures corresponds to : 16,000 km2; 600,000 soil polygons delimited by 15 million intermediate points (vertex); 6,000 pedological symbols; 700MB. The advantages of this computerized cartographic database are continuity, legibility, accessibility and many possibilities of thematic analyses. [less ▲]

The usefulness of various soil parameters to predict naturally occurring levels of some metallic trace elements (MTE) in soils has been studied for some agricultural and forest soils of Southern Belgium. The driving factors of the content in Cu, Ni, Pb, and Zn were investigated through multi-scale comparisons. This paper deals with multivariate and regression analysis of the results. [less ▲]

Ce rapport final présente la synthèse de l'ensemble des activités menées dans le cadre de la convention d'étude pour la "Mise en oeuvre du projet de cartographie numérique des sols de Wallonie". L'objectif général de cette convention s'est déroulé sur la période du 1er février 2001 au 30 avril 2004. Objectif général : "Mise en oeuvre du projet de cartographie numérique des sols de Wallonie sur base de la carte des sols de l'I.R.S.IA." Objectifs particuliers : 1. Scannage et géoréférencement des planchettes couleurs éditées à 1/20 000. 2. Digitalisation des planchettes éditées (1/20 000) et non éditées (1/10 000) couvrant le territoire de la Région wallonne. 3. Evaluation de la faisabilité d'une récupération des planchettes ou parties de planchettes digitalisées dans le cadre des conventions financées par la Région. Le travail de digitalisation intégrera les considérations suivantes : * Géoréférencement des données cartographiques dans le système Lambert 72 ; * Ajustement des plages de sols de vallées et de dépressions par rapport au réseau hydrographique du fond topographique I.N.G. à 1/10 000 ; * Ajustement des plages de sols par rapport aux figures de terrain présentent sur le fond topographique I.G.N. à 1/10 000 ; * Etablissement de la continuité cartographique et thématique entre toutes les planchettes digitalisées ; * Mise au point d'une légende pédologique unique et homogène pour tout le territoire wallon.

Among other soil characteristics, those related to the nutrient status and the content in metallic trace elements (MTE) originate from both natural factors and land management. A methodological framework has thus been set up to evaluate the importance of natural driving factors -the so-called pedo-geochemical background- of the spatial distribution of mineral elements in soils and also to compare the current levels of MTE content in agricultural soils with natural values. References for natural, typical, and suspicious values are stated in a Reference Soil System (RSS) which is based on the identification of relationships between geology, relief, and soil, and on the consideration of soil volumes. It integers the land cover and also takes into account the spatial dependance between measurement points in order to estimate the change detection sensibility. Thanks to a comparison-based methodology, to the existence of a detailed soil map, and to the integration of various spatial representation techniques, an image of the state of the soils has been drawn and can serve as a reference for the prediction and the interpretation of point values, for the evaluation of a particular land utilization type, and as a base for the monitoring of soil quality. The reference values about natural and usual content in MTEs for various soil horizons that are proposed reveal especially a relatively weak level of contamination for agricultural soils. [less ▲]
