Interpolated NTM (interpolated digital terrain model) from LiDAR - SCoT Lille Metropole and MEL - 2018

Description

The 2018 NTM was produced from LiDAR data. The influence of this product covers the limits of the Territorial Coherence Scheme (SCoT) in application on the communes forming part of the MEL, the Community of Communes of the Haute Deûle (5 communes south of the metropolitan territory) and the Community of Communes Pévèle Carembault (38 communes south-east of the metropolitan territory). In addition, this right-of-way slightly exceeds this administrative limit, making it possible to have data on the border sector to the north-west and north-east of the current metropolitan territory as well as the neighbouring territories, on 2 to 8 kms outside the limits of the SCoT. This type of data makes it possible to represent the terrain relief in the form of a raster grid.The source data (LiDAR) makes it possible to discriminate between soil and over-ground data, and therefore to exclude built information, vegetation, etc. **Warning about the use of the product:** Unlike the non-interpolated NTM, areas without data (covered by frame, vegetation too dense for the signal to reach the ground or water areas) were interpolated so that the frame was continuous. The data are therefore calculated afterwards and not by the sensor during the acquisition campaign. The relief under very dense forest cover should be considered as possible relief, the areas in water and covered by buildings also. To benefit from an uninterpreted field data, it will be necessary to use the *MNT (digital field model) from the LiDAR - SCoT Lille Metropole and MEL - 2018*. The data is available for download, in WMS and WCS streams. The WCS feed gives access to the raw data without downloading it completely and thus makes it possible to perform calculations. This method is therefore indicated if studies are carried out at sub-municipal level. For larger-scale studies, downloading may be considered. **Associated data:** * Point cloud from LiDAR - SCoT Lille Metropole and MEL - 2018 * MNT (digital field model) from LiDAR - SCoT Lille Metropole and MEL - 2018 * MNE (digital elevation model) from LiDAR - SCoT Lille Metropole and MEL - 2018 * MNTB (digital model of land and buildings) from LiDAR - SCoT Lille Metropole and MEL - 2018 **Reference sheet for the acquisition of derivatives:** * LIDAR - MEL - SCoT - 2018
