Simple download service (Atom) of the dataset: Modelling of urbanisation (urban stains), situation in 1980 in Franche-Comté

Urban stain modelling in Franche-Comté in 1980. 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.1980年弗朗什-孔泰（Franche-Comté）地区城市斑块建模研究。 “城市化动态——Urban Taches”工具可对随时间演化的城市化空间进行建模分析。城市斑块通过下述模型生成：先以建筑为基准向外扩张50米，再向内侵蚀40米。 该动态地图依据建筑建造年份呈现城市斑块的空间分布，自1950年起以每10年为时间间隔对城市斑块进行可视化展示。 城市斑块对象源自法国国家地理研究院（IGN）的数据库（BDParcellaire与BDTopo）中的建筑数据。 建筑的“建造年份”信息取自2011年1月1日起的法国公共财政总局（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将生成“无日期标注”的城市斑块（此类建筑主要为农业与工业用途）。文件“Tache_urbane_NC_R43.TAB”包含“无日期标注”城市斑块的地理信息系统（GIS）数据。 请注意：公共领域建筑未被纳入MAJIC数据库。 人口数据取自法国国家统计与经济研究所（INSEE）官方网站。
