Napoleonic cadastre (section leaves)

Napoleonic cadastre by section sheets (original and georeferenced) in the territory of the department of Hauts-de-Seine. * * * The cadastre refers to the documents used to establish the property tax base. This dataset concerns the plans of the “napoleonian” cadastre, drawn up in 1802 for certain municipalities, but regulatoryly carried out from 1807 and modified until the 1860s for all the communes of the future department of Hauts-de-Seine. Produced by the tax administration, the Napoleonic cadastre entered the archives départementales des Hauts-de-Seine by devolution of the Archives départementales de Paris (for the municipalities belonging to the former department of the Seine) and the Yvelines (for municipalities belonging to the former department of Seine-et-Oise), as well as by payments from the tax services and the department of the Ponts et-chaussées de Boulogne, which explains the multiple quotations. The plans are thus rated in D6P, 3P1 and 3P3, depending on their origin. There have been several successive revision campaigns for the municipalities of the former department of the Seine. It should be noted that the territory of Hauts-de-Seine experienced many changes during the 19th century: creation of the communes of Levallois-Perret in 1866 (from the communes of Neuilly-sur-Seine and Clichy), Malakoff in 1883 (from the commune of Vanves), Bois-Colombes in 1896 (from the commune of Colombes), La Garenne-Colombes in 1910 (from the commune of Colombes) and finally of Villeneuve-la-Garenne in 1929 (from the commune of Gennevilliers). Moreover, the Haussmann reform of 1860 had the effect of integrating into Paris all or part of certain communes, such as Montrouge, Vanves, Issy-les-Moulineaux, Neuilly-sur-Seine, Clichy, while the village of Billancourt, which belonged to the commune of Auteuil, was attached to Boulogne. Finally, some exchanges of territories were carried out, such as between Vélizy and Meudon, or between Arcueil and Montrouge. Cadastre plans can be a first step in the search for landowners of a plot or built property. It is then necessary to consult the states of sections and matrices. **Context** After posting the departmental assembly of the Napoleonic cadastre in January 2020, the Hauts-de-Seine Department completes its offer by offering this same data to the section sheet. Indeed, the Napoleonic cadastre was formed throughout the 19th century and several vintages may exist for the same section leaf. For the departmental assembly, only the oldest section sheets were georeferenced and assembled in order to offer a coherent and homogeneous product. This dataset offers for download all available section sheets (source sheets and georeferenced sheets), by municipality and for each existing vintage. **Glossary** Georeferencing Georeferencing is the action of linking a plan, a geographical object or an image to a system of geographical coordinates in order to ensure its geolocation and superposition with other geographical objects. The leaves of the Napoleonic cadastre were georeferenced in projection RGF93 — CC49, which is the coordinate system operated by the Hauts-de-Seine Department. **Specific observations** The Napoleonic cadastre is made available by municipality and vintage. For each municipality of the department, one or more vintages of the Napoleonic cadastre are offered. It is then possible to download by clicking on the file name, the so-called source sheet in JPG format or the georeferenced sheet in ZIP format containing the sheet in JPG format and the georeference file in JGW format. According to vintages and municipalities, the listings of the cadastral leaves differ. In order to make these quotations comprehensible for users of the Open Data Portal of the Hauts-de-Seine Department and homogeneous from one vintage to the next, the following nomenclature has been put in place: CODE-COMMUNE_DATE_CODE-SECTION_NUM-SHEET. For example, for sheet 2 of section A of the 1808-1809 vintage, Antony has the following name: ANT_1808-1809_A_2. In the case where there are several parts for a sheet (as is the case for sheet 1 of Section A of the 1808-1809 vintage to Antony), an incremental number makes it possible to distinguish the two parts. This gives our example the following names: ANT_1808-1809_A_1_01 and ANT_1808-1809_A_1_02. In case the date is missing, it is noted n.d in the file name. The same applies to the section and the sheet. If they are missing, they are marked s.s and s.f. Georeferenced leaves have the same name as the source leaves but with the _cale suffix. **Related links** Link to the website of the cadastre archives [Departmental Archives: cadastre Online](http://consultation.archives.hauts-de-seine.net/mdr/index.php/rechercheTheme/requeteConstructor/1/1/R/0/0) **Related data** Link to the departmental assembly of the Napoleonic cadastre (Napoleonian cadastre (departmental assembly)](https://opendata.hauts-de-seine.fr/explore/dataset/fr-229200506-cadastre-napoleonien-assemblage-departemental)
