Raw terrains built from LIDAR tiles for some villages of the Nied catchment

The dataset contains digital terrain models (DTM) built from ground and building classes of LIDAR HD tiles produced by IGN, and saved as .raw images to be imported as Terrain objetcs in the Unity game engine.The process is carried out by using the ReFlood LIDAR viewer (based on the lastools package). The viewer also allows for local modifications to take out structures, or correct inaccuracies. To date, the dataset contains raw terrains for Boulay-Centre and Filstroff vilages.

本数据集包含由法国国家地理研究所（IGN）生产的激光雷达高清瓦片（LIDAR HD tiles）的地面与建筑分类结果构建的数字地形模型（DTM），并以.raw格式图像存储，可在Unity游戏引擎中导入为地形（Terrain）对象。该数据集的生成流程依托基于lastools工具包开发的ReFlood激光雷达查看器（ReFlood LIDAR viewer）完成。该查看器还支持进行局部修改，以移除冗余结构或修正精度偏差。截至当前，本数据集已收录布拉伊中心（Boulay-Centre）与菲尔斯特罗夫（Filstroff）两个村庄的原始地形数据。
