The estate comprises 120 buildings, including the King\u2019s Apartment, the Royal Chapel, and the House of Mirrors. Deeper in the park, visitors will find the Petit Trianon estate; the Versailles Orangerie; and several parks and gardens designed by King Louis XIV\u2019s gardener, Andr\u00e9 Le N\u00f4tre."},{"acf_fc_layout":"image","image":596942,"image_position":"left","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"For much of the estate\u2019s existence, the finer details of managing its parks mostly survived unofficially as institutional knowledge passed down through the years. For example, only a few people at any time understood the water network and which keys operated the extraordinary hydraulic system.\r\n\r\nIn 1995, France\u2019s ministries of culture and budget formalized park operations under the Palace, Museum, and National Estate of Versailles (known by the acronym EPV), a public corporation with administrative and financial autonomy. EPV now employs 900 people.\r\n\r\nIn the mid-2000s, EPV took steps to implement a new management plan. One of the goals was to design a GIS-based tool that would help visitors understand the estate\u2019s history and heritage. Its sheer size proved daunting.\r\n\r\n\u201cThe estate occupies 140 plots, spread over eight cities, with roads and even railways,\u201d \u00c9lise Legrand, EPV\u2019s GIS specialist, said during a talk at a GIS event last year. \u201cThis presents management difficulties and [consistency] problems. EPV had access to digital databases, but there was no common link between them.\u201d\r\n\r\nIn 2017, EPV launched a garden management plan for the estate that called for a GIS solution. The agency partnered with Arx iT, a GIS services company and longtime Esri partner based in France and Switzerland. ArcGIS Enterprise provided the tools to create and publish web maps, web apps, and web services."},{"acf_fc_layout":"image","image":596952,"image_position":"right","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"The GIS infrastructure became operational in 2022. Arx iT integrated existing data from multiple sources. A basemap was gradually assembled by looking at historical documents.\r\n\r\n\u201cIt\u2019s a fantastic challenge to digitize and assemble dozens of Cassini maps in Lambert projection,\u201d says David Boill\u00e9e, a project manager and GIS architect at Arx iT.\r\n\r\nBoill\u00e9e\u2019s team discovered that some of the gardens, waterways, and flowerbeds had remained virtually the same over the centuries. These served as reference points for much of the geographic data.\r\n\r\nEPV uses two GIS applications as part of its management plan.\r\n\r\n<em>Si Versailles m\u2019\u00e9tait trac\u00e9<\/em> (which translates as <em>if Versailles was drawn for me<\/em>), the first app, overlays aerial imagery with 14 georeferenced old maps of the Versailles estate, dating back as far as 1699, and allows users to swipe between the new and the old. The app offers a unique opportunity to discover the estate from a historical perspective, see the evolution of its buildings and the layout of its land, and examine previously inaccessible map archives. From an operational perspective, it is used for architectural studies, archaeological excavation, and historical reconstruction.\r\n\r\nThe second application is solely for internal use and forms the backbone of the management plan. A global viewer within the app uses a dedicated basemap that provides details of the grounds, including the wooded areas, walkways, and buildings, as well as the walls and fences that mark the boundaries of the estate.\r\n\r\n\u201cFor example, the queen\u2019s grove was restored in 2020,\u201d Legrand said. \u201cWith the global viewer, we can see the gap between what currently exists and what existed before restoration work was underway.\u201d"},{"acf_fc_layout":"image","image":596962,"image_position":"left","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"Dedicated map layers provide more specific information relevant to the maintenance of the park. These include details on the gardens, driveway conditions, sculptures, benches, and trash receptacles. Clicking on a pop-up window reveals related details for every attribute.\r\n\r\n\u201cA user can examine the maintenance history of an individual bench,\u201d Legrand noted.\r\n\r\nOver time, she added, the viewer will evolve as more data and layers are added to the map.\r\n\r\nIn the coming years, EPV will focus on the behind-the-scenes networks\u2014such as electricity, water, and fiber optics\u2014that are essential for the ongoing management of Versailles. EPV also plans to create a history of the landscaping of Versailles, displaying the evolution of trees and plantings over the years. A mobile app is also in the works.\r\n\r\nAs information accrues and layers are added to the map, details of Versailles\u2019 past are revealed, helping to ensure its future.\r\n\r\n\u201cIn effect,\u201d Legrand said, \u201cGIS helps different sources of information exist in a dialogue with one another.\u201d"},{"acf_fc_layout":"sidebar","layout":"standard","image_reference":null,"image_reference_figure":"","spotlight_image":null,"section_title":"","spotlight_name":"","position":"Center","content":"Xavier Fodor, editor in chief of <em>SIGMAG SIGTV.FR<\/em>, the largest quarterly French-language magazine dedicated to GIS and French-speaking users of ArcGIS technology, contributed to the reporting of this article.","snippet":""}],"references":null},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v25.9 (Yoast SEO v25.9) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>GIS Reveals the Details of Versailles\u2019 Past to Help Plan for the Future | Summer 2023 | ArcNews<\/title>\n<meta name=\"description\" content=\"Two web apps are now used to manage the nearly 2,000 acres that make up the Palace of Versailles.
