Graphic cadastre of the Municipality of Lanester

The cadastre plan is an administrative document that proposes the only large-scale parcel plan covering the national territory. The plan of a commune’s cadastre is divided into sections, which can be divided into subdivisions of sections, commonly referred to as “plan sheets”. — The cadastral section is a part of the communal territory whose perimeter is usually made up of boundaries of relatively stable character on the ground (road, roads, watercourses...). — The plot is the basic cadastral unit. It is a single-contained plot located in the same place and belonging to the same owner. — The plan of the cadastre in vector format derives mainly from the digitisation of the cadastral plan paper or raster carried out in the framework of agreements with local and regional authorities. To a lesser extent, it was produced directly in digital format in the context of the production of new cadastral plans (recasting procedure provided for by Law No 78-645 of 18 July 1974) or agricultural and forestry land development (commonly referred to as “rememberments”). Cadastral plans in vector format in metropolitan France are currently georeferenced in the legal system (RGF93) using “conical 9 zones compliant” projections. Georeferencing of vector plans could be obtained: — during their making (in the case of very recent cadastral plans); — after conversion of their coordinates expressed in the Lambert zones projection; — during vectorisation (cases not initially georeferenced) **Collection context** The cadastral plans in vector format managed and exported by the DGFiP services were produced from the other field. Depending on the plan sheets, vectorisation and georeferencing conditions are diverse. This information is available on the fact sheets of each of the municipalities. **Collection method** The cadastral plans in vector format managed and exported by the DGFiP services were produced from the other field.

Cadastral plans are of several types: —updated plans: these are cadastral plans updated from the frame of the Napoleonic cadastral plans. They're not regular plans. These plan sheets are identifiable by their single letter section (e.g. “section A”). The scales of plan sheets can be variable and are mainly at the following scales: 1/1250, 1/2500 and 1/5000; — ‘regular’ plans: these are plans that were made during the renovation of the cadastre without repeating the pattern of Napoleonic plans. Among these plans, there are two categories: — the so-called “renewed” plans: these are plans which have not been the subject of a conflicting delimitation of the properties on the ground when they were drawn up; — “remade” plans which have been subject to conflicting demarcation of properties; Where the cadastral plan is no longer able to meet the needs (in particular because of its scale or its possible inaccuracy), it may be redrafted in accordance with the ‘reshuffle’ procedure laid down by Law No 78-645 of 18 July 1974. Cadastral plans resulting from land development operations are referred to as “remembered plans”. The identifier of a plan sheet is of the form: “DDCCCPPPSSNN” where: — “DD” is the number of the department; — “CCC” means the INSEE code of the municipality; — “PPP” is the section prefix. By default this prefix is equal to “000” except in the following cases: — in case of absorption of a commune, this prefix shall have the value of the INSEE code of the absorbed municipality; — in the case of municipalities in arrondissements, this prefix contains the district code (for Paris from 101 to 120, for Lyon from 381 to 389, for Marseilles from 201 to 216, in the case of the city of Toulouse, this is the district code taking the values from 801 to 846). — “SS” is the designation of the section “cadastrale” (in case of a single section letter, the section letter is preceded by the number “0” e.g. “section 0A”); — “NN” is the sheet number (“01” by default) For more information, see [the metadata on the Isogeo catalog](https://open.isogeo.com/s/0bd17a2a330842c68ec4a412d1df6824/AiCyPK6W8fg012l-vHV0s5tPry5b0/r/952ed8febd3b4b74b1ddfa39dae78c5a).地籍图（cadastre plan）是一份行政文件，旨在提供覆盖全国领土的唯一大比例尺宗地规划图（parcel plan）。 公社的地籍图划分为若干地籍区段（section），区段可进一步细分为地籍区段细分单元，通常称为“图幅（plan sheets）”。 — 地籍区段是公社领土的一部分，其边界通常由地面上性质相对稳定的地物构成，如道路、水道等。 — 宗地（plot）是基本地籍单元，指坐落位置一致、权属归同一主体的独立封闭地块。 — 矢量格式地籍图主要来源于与地方及区域当局签订协议框架下开展的纸质或栅格地籍图数字化工作。另有小部分矢量地籍图是在新编地籍图（如依据1974年7月18日第78-645号法律规定的重编流程）或农林土地开发场景下（此类成果通常称为“记要图（rememberments）”）的制作过程中，直接以数字格式生成的。 当前法国本土的矢量格式地籍图均采用“9分带圆锥兼容投影”，在地籍法定坐标系（RGF93）中完成地理配准。矢量图的地理配准可通过以下三种途径实现： — 在制图过程中完成配准（适用于极新近的地籍图）； — 通过转换Lambert分带投影坐标系下的坐标完成配准； — 在数字化过程中完成配准（适用于初始未进行地理配准的图件）。 **采集背景** 法国财政公共会计总局（Direction Générale des Finances Publiques, DGFiP）相关部门管理并对外导出的矢量格式地籍图，均源于前述其他数据源。不同图幅的数字化与地理配准条件存在差异，相关信息可查阅各自治市的详情说明文档。 **采集方法** 法国财政公共会计总局（Direction Générale des Finances Publiques, DGFiP）相关部门管理并对外导出的矢量格式地籍图，均源于前述其他数据源。不同图幅的数字化与地理配准条件存在差异，相关信息可查阅各自治市的详情说明文档。 地籍图主要分为以下几类： — 更新型地籍图：此类地籍图以拿破仑地籍图为基础框架进行更新，并非原生常规地籍图。其图幅可通过单个字母标识的区段进行识别（例如“区段A”）。图幅比例尺可变，主流比例尺为1/1250、1/2500及1/5000； — “常规”地籍图：此类地籍图在地籍重编过程中编制，未沿用拿破仑地籍图的编制模式。其中又分为两类： — 所谓“续编”地籍图：指编制过程中未出现地面宗地界址权属争议的地籍图； — “重制”地籍图：指编制过程中针对地面宗地界址开展过冲突界址划定工作的地籍图； 当地籍图无法满足使用需求（尤其是因比例尺过小或精度不足时），可依据1974年7月18日第78-645号法律规定的“重编流程”进行重新编制。 由土地开发项目生成的地籍图被称为“记要地籍图（remembered plans）”。 图幅标识符采用“DDCCCPPPSSNN”格式，各部分含义如下： — “DD”：省份编号； — “CCC”：自治市的法国国家统计与经济研究所（INSEE）编码； — “PPP”：区段前缀。默认情况下该前缀为“000”，以下情形除外： — 若某自治市被并入其他自治市，该前缀需使用被并入自治市的INSEE编码； — 若自治市隶属于区（arrondissement），该前缀需包含区代码（巴黎的区代码范围为101至120，里昂为381至389，马赛为201至216，图卢兹的区代码范围为801至846）； — “SS”：地籍区段标识。若区段为单个字母标识，需在字母前补数字“0”，例如“区段0A”； — “NN”：图幅编号（默认值为“01”） 如需获取更多详情，请参阅[Isogeo目录元数据](https://open.isogeo.com/s/0bd17a2a330842c68ec4a412d1df6824/AiCyPK6W8fg012l-vHV0s5tPry5b0/r/952ed8febd3b4b74b1ddfa39dae78c5a)。
