Map Viewing Service (WMS) of the dataset: Urbanisation modelling (urban stains), situation in 2011 in Franche-Comté

Urban stain modelling in Franche-Comté in 2011. The Urbanisation Dynamics — Urban Taches tool offers a modeling of urbanised spaces over time.Urban spots were generated by the application of the following model: expansion distance of + 50 m around the buildings then erosion of -40 m. The dynamic map depicts urban spots according to the building years.Urban spots have been visualised in 10 years since 1950. Urban spot objects were generated from the buildings of the IGN databases (BDParcellaire and BDTopo). The “year of construction” information of the buildings comes from the DGFiP land database (MAJIC files) as of 1 January 2011. This source is not exhaustive. Buildings whose year of construction is unknown have generated “undated” urban spots (mainly for buildings for agricultural and industrial use). The file “Tache_urbane_NC_R43.TAB” contains GIS data for “undated” urban spots. Please note: the public domain is not listed in the MAJIC database. Population data have been downloaded from the INSEE website.2011年弗朗什-孔泰（Franche-Comté）城市斑块建模研究。 「城市化动态-城市斑块（Urban Taches）」工具可对随时间变化的城市空间进行建模。城市斑块通过以下规则生成：先以建筑物为中心向外扩张50米，随后向内侵蚀40米。该动态地图依据建筑建造年份呈现城市斑块，已按10年为间隔可视化了1950年以来的城市斑块分布。 城市斑块对象源自法国国家地理研究所（Institut Géographique National，IGN）的数据库（BDParcellaire与BDTopo）。建筑物的「建造年份」信息取自2011年1月1日的法国公共财政总局（Direction Générale des Finances Publiques，DGFiP）土地数据库（MAJIC文件）。 该数据源并非全覆盖：建造年份未知的建筑物会生成「无日期」城市斑块，此类斑块主要对应农业与工业用途建筑。 文件「Tache_urbane_NC_R43.TAB」包含地理信息系统（GIS）的「无日期」城市斑块数据。 请注意：公共域建筑未被纳入MAJIC数据库。 人口数据取自法国国家统计与经济研究所（Institut National de la Statistique et des Études Économiques，INSEE）官网。
