Urbanisation modelling (urban stains), situation in 1960 in Franche-Comté

Urban stain modelling in Franche-Comté in 1960. 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.1960年弗朗什-孔泰（Franche-Comté）城区斑块建模。 「城市化动态——城市斑块（Urban Taches）」工具可对随时间演变的城市化空间进行建模。城市斑块的生成遵循以下规则：以既有建筑物为基准向外拓展50米，随后向内侵蚀40米。 该动态地图依据建筑物建造年代展示城市斑块，自1950年起以每10年为间隔进行可视化呈现。 城市斑块对象源自法国国家地理研究院（IGN）数据库（BDParcellaire与BDTopo）中的建筑物数据。 建筑物的「建造年份」信息取自2011年1月1日起更新的法国公共财政总局（DGFiP）土地数据库（MAJIC文件），该数据源并非完整覆盖所有对象。 建造年份未知的建筑物将生成「无年代标注」城市斑块（此类斑块主要对应农业与工业用途的建筑物）。文件"Tache_urbane_NC_R43.TAB"包含「无年代标注」城市斑块的地理信息系统（Geographic Information System，简称GIS）数据。 请注意：公共领域用地未被收录于MAJIC数据库。 人口数据下载自法国国家统计与经济研究所（INSEE）官方网站。
