Census of brownfields in 2018 in the department of Marne.

Description:

Since 2009, the departmental directorate of the Marne territories has been carrying out a census of the land resources available within the main urban areas of the Marne. This census concerns land rights of way for known or probable brownfields of all types (industrial, railway, military, etc.). The area retained for brownfields is 2 000 m², threshold defined as potentially an issue. This census is not exhaustive.
Census conducted until October 2018.

Genealogy:

A first census of brownfields was carried out from the databases of the Ministry of Ecology, Sustainable Development and Energy “BASIAS” and “Basol”, listing polluted sites. Visits by the territorial referents (RT) of the departmental directorate of the territories were then carried out on site and made it possible to complete the first census. The data is geolocated in the form of polygons using the parcelal cD (default of digitised cadastre).

Metadata:
ID: identification of wasteland by number
ENTITE: current state (fridge or wasteland converted)
CD_INSEE: INSEE code
NOM_COM: name of the municipality
DESCRIPTION: current state of land or built at census date
ACTIV: past or new activity for brownfields
ENTER: name of company and/or owner, who is or was installed
ADDRESS: address of the wasteland
PROJECT: project in progress at census date if known
COMMENT: further information on the situation of the wasteland at the last date of its census.
SOURCE: Source of information.
Date_MAJ: date of update

The geolocation data is in the form of a polygon.

### 普查概况
自2009年起，马恩省（Marne）领土管理局便针对马恩省主要城区范围内的可用土地资源开展普查工作。本次普查覆盖各类已知或疑似棕地（brownfields）的土地通行权与产权，涵盖工业、铁路、军事等多种类型。本次普查设定的棕地最小面积阈值为2000平方米，该阈值被认定为具备潜在关注价值的临界标准。本次普查并非全覆盖，且数据采集工作已于2018年10月终止。

### 数据溯源
首轮棕地普查依托法国生态、可持续发展与能源部的"BASIAS"与"Basol"污染场地数据库开展，初步梳理出污染场地清单。随后，马恩省领土管理局的属地专员（RT）开展实地踏勘，完成了首轮普查的补充完善工作。本次数据以多边形矢量形式进行地理定位，采用地块数字化地籍（parcelal cD）作为定位基准。
