The Observatoire des Sols à l’Echelle Communale (also referred to as “OS communale” or “OSCOM”) is a geomatic tool developed in the framework of a partnership work involving the DRAAF of the former Haute-Normandie region (on the initiative of the project), the DDTM Seine-Maritime, the DDTM de l’Eure and the DREAL of the former region Haute-Normandie under the auspices of a Copil SIG interservice DRAAF/DREAL/DDTMs. It consists of generating vintage graphic layers using a successive integration algorithm of a set of reference graphic layers, of the same vintage (except the forest layer dating from 2000), e.g. from the BD-TOPO® and the BD-FORET® of IGN©, the agricultural GPR of the ASP and the Majic parcel of DGFiP. The objective is therefore to be able to estimate land cover and its evolution at the municipal or supra-communal level using a pragmatic approach based on a purely computer-based processing of heterogeneous layers, in particular in terms of precision, which implies taking precautions as to the use of the results obtained. The nomenclature used for this project is based on level 2 of the Corine Land Cover nomenclature. It consists of 5 posts at level 1 (0-Mixed spaces, 1-Artificised territories, 2-Agricultural territories, 3-Forests and semi-natural environments, 5-Wurfaces in water) and 14 level 2 posts (00-Mixed spaces, 11-urbanised areas, 12-industrial or commercial areas and communication networks, 13-Mines, landfills and construction sites, 14-Non-agricultural artificialised green spaces, 15-Unbuilt spaces awaiting requalification, 20- Mixed agricultural land, 21-Arable land, 22-Permanent crops, 23-Prairies, 24-Other agricultural land, 31-Forests, 32-Milieux with shrub and/or grass vegetation, 51-Mainland waters).市镇尺度土壤观测系统（Observatoire des Sols à l’Echelle Communale，下称“OS communale”或“OSCOM”）是一款地理信息工具，由原上诺曼底大区农业食品与林业局（DRAAF）发起项目，联合滨海塞纳省领土与海洋局（DDTM Seine-Maritime）、厄尔省领土与海洋局（DDTM de l’Eure）以及原上诺曼底大区环境规划与住房局（DREAL），在DRAAF/DREAL/DDTMs跨部门地理信息系统（SIG）指导委员会（Copil SIG）的统筹下合作开发而成。 该系统通过逐次整合算法，对一组同年代的参考制图图层（2000年的森林图层除外）进行融合，以生成对应年代的制图图层；所用参考数据源包括法国国家地理研究院（IGN©）的BD-TOPO®、BD-FORET®数据集，法国农业与食品署（ASP）的农业宗地登记（GPR）数据，以及法国公共财政总局（DGFiP）的Majic宗地数据。 本工具的研发目标是：通过纯计算机化的异构图层处理路径（尤其需考量各图层间的精度差异），以务实的方式实现市镇或跨市镇尺度的土地覆盖及其动态变化估算，这意味着对所得结果的使用需采取审慎态度。 本项目所采用的分类体系基于欧共体环境信息观测站（Corine Land Cover）土地覆盖分类体系的二级分类标准。该分类体系包含5个一级分类项（0-混合用地、1-人工地表、2-农业用地、3-森林与半自然环境、5-水域），以及14个二级分类项（00-混合用地、11-建成区、12-工业或商业用地与交通网络、13-矿区、填埋场与建筑工地、14-非农业人工绿地、15-待更新改造的未建成用地、20-混合农业用地、21-耕地、22-多年生作物种植地、23-牧草地、24-其他农业用地、31-森林、32-灌丛与/或草本植被生境、51-内陆水域）。
