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).市镇尺度土壤观测平台（Observatoire des Sols à l’Echelle Communale，简称“OS communale”或“OSCOM”）是一款地理信息学工具，其开发依托于跨机构合作框架，参与方包括原上诺曼底大区的大区农业、食品与林业局（DRAAF，由本项目发起倡议）、塞纳-马恩省领土与海洋局（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的大区环境、规划与住房局（DREAL），相关工作由DRAAF/DREAL/DDTMs跨部门SIG指导委员会（Copil SIG）主持开展。该工具通过对一组同年代参考矢量图层（森林图层除外，其数据年代为2000年）采用逐次集成算法生成目标矢量图层，所用参考数据源包括法国国家地理研究院（Institut Géographique National，简称IGN©）的BD-TOPO®地形数据库与BD-FORET®森林数据库、农业服务与支付局（Agence de Services et de Paiement，简称ASP）的农业用地GPR数据库，以及法国公共财政总局（Direction Générale des Finances Publiques，简称DGFiP）的Majic地块数据库。本工具的研发目标为，依托纯计算机处理异构图层的务实方法，实现市镇或跨市镇尺度下的土地覆被及其变化估算；鉴于不同图层在精度层面存在差异，使用所得结果时需采取必要的谨慎措施。本项目采用的分类体系基于CORINE土地覆被（Corine Land Cover）分类体系的二级分类标准。该分类体系包含5个一级分类单元（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个二级分类单元（00-混合用地、11-城区、12-工业/商业用地与交通设施、13-矿山、填埋场与建筑工地、14-非农业人工绿地、15-待改造未开发用地、20-混合农业用地、21-耕地、22-多年生作物用地、23-草地、24-其他农业用地、31-森林、32-灌丛与/或草本植被区域、51-内陆水域）。
