Tuscany Region - PIT - Invariants - Qgis Project

This Qgis project brings together the four projects carried out to draw up the maps of the four invariants supporting the cognitive framework of the four invariants identified in the context of the review of the landscape discipline of the PIT of the Tuscany Region. The original projects were designed with the subsequent creation of as many raster cards in mind. This project brings together and partly simplifies the original projects by eliminating duplication of common data, etc. The datasets used in the project, in shape format, are not documented individually as they are functional to the creation of raster maps each of which is self-explained through its own legend and specific metadata, to which, however, please refer for more information (see Download resources: http://bit.ly/1GBJkjL). It should be recalled that the results of any vector processing, in gis environment, of the project data, are to be used at the original scales of the raster cards derived from them (1:50,000 and 1:250,000).The project consists of the following thematic layers:Joining framework 50K – Joining framework of the sheets of the Italian map 1:50,000 of the IGM on the basis of which the sheets of the cards of the invariants I, II, III have been divided. Municipal areas – Municipal limits Landscape areas – Limits of the landscape areas identified by the Regional Landscape PlanInvariant I – Map of morphogenetic systems – Cartography at a scale of 1:50,000, covering the entire territory of the Region of Tuscany, aimed at representing the morphogenetic characteristics of the Tuscan territory, or the objectively recognisable elements of the physical structure of the landscape, defined by a combination of the factors governing the development of the forms of relief such as structural, temporal and geological factors. Invariant II – Map of the ecological network – 1:50,000 scale mapping, covering the entire territory of the Tuscany region, aimed at highlighting the structural and functional elements of the regional ecological network. The map is designed to represent the level of ecological fragmentation at the regional scale, the source nuclei of biodiversity for both forest ecosystems and for agricultural and pastoral ecosystems, the matrix of connectivity as well as the critical elements for the functionality of the network. Invariant III – Map of the urbanised area – Map in 1:50,000 scale, covering the entire territory of the Tuscany region. The association of the attributes relating to the building periodisation allows a series of elaborations aimed at the exclusive representation of the growth of the settlements or the representation of the building at a given time thresholdInvariant IV – Map of rural morphotypes – Map in 1:250,000 scale, extended to the entire territory of the Tuscany region. The map aims to provide a representation in the form of areas of the types of rural landscape present in the region, understood as recognizable forms resulting from the intersection of different factors such as geomorphological, settlement, naturalistic, cultural.本QGIS项目整合了四项相关工程，这些工程用于绘制支撑四项不变量（invariants）认知框架的专题地图，而该四项不变量是在托斯卡纳大区（Tuscany Region）PIT框架下的景观学科审查工作中确定的。原始工程的设计初衷为后续生成多张对应栅格地图。本项目整合并简化了原始工程内容，消除了公共数据重复等冗余问题。 本项目采用的SHP矢量格式数据集未单独归档，因其仅服务于栅格地图的制作；每张栅格地图均可通过自身图例与专属元数据自行阐释，如需获取更多信息，请参阅相关指引（详见下载资源：http://bit.ly/1GBJkjL）。需特别说明：对本项目数据在GIS环境中开展任意矢量处理后得到的成果，必须遵循其衍生栅格地图的原始比例尺使用，即1:50000与1:250000。 本项目包含以下专题图层： 1. 接合框架50K——以意大利地理军事研究所（IGM）制作的1:50000比例尺意大利国家地图分幅为基础，整合得到的分幅接合框架，据此划分了不变量I、II、III的地图分幅。 2. 市域范围——市级行政界线 3. 景观区域——《区域景观规划》划定的景观区域界线 4. 不变量I——地貌成因系统地图：比例尺1:50000，覆盖托斯卡纳大区全域，用于表征托斯卡纳区域的地貌成因特征，即景观物理结构中可客观识别的要素，由支配地貌形态发育的构造、年代与地质等多类要素组合定义。 5. 不变量II——生态网络地图：比例尺1:50000，覆盖托斯卡纳大区全域，用于凸显区域生态网络的结构与功能要素。本地图旨在表征区域尺度的生态破碎化程度、森林与农牧生态系统的生物多样性源斑块、连通性基质，以及保障网络功能的关键节点。 6. 不变量III——城市化区域地图：比例尺1:50000，覆盖托斯卡纳大区全域。通过关联建筑年代分期属性，可开展一系列专属分析：用于仅展示聚落扩张过程，或表征特定时间节点的建筑分布情况。 7. 不变量IV——乡村地貌类型地图：比例尺1:250000，覆盖托斯卡纳大区全域。本地图以区域划分的形式，展示区内现存的乡村景观类型，此类景观可被识别为地貌、聚落、自然保育、文化等多因素叠加形成的可辨识形态。
