莱达Surveys Reveal Devon's Hidden Archaeological Features

Aerial mapping company Bluesky has used aircraft-mounted lasers to create 3D maps of potentially important archaeological sites in Devon, England, UK. Funded by Historic England (formerly English Heritage), the Lidar surveys were commissioned by Devon County Council’s Historic Environment team with support from the Blackdown Hills Area of Outstanding Natural Beauty (AONB) and The East Devon AONB. Using a range of visualisation techniques, the Bluesky Lidar data will be modelled to provide accurate representations of earthwork remains, providing new information for known monuments and revealing previously unknown sites. The Bluesky Lidar data has already been used to provide valuable information in advance of a public consultation on road improvement works on the A30 trunk road.

LIDAR数据是考古学景观研究的宝贵工具，因为它提供了一个非常准确的地面模型，Cain Hegarty评论，AC考古学的项目经理和德文县议会历史环境队的一部分。他补充说，数据可以以多种方式重新可视化以提供同一站点的多种视图，并且在树木状地区可以揭示考古学现场调查和传统的空中调查中往往无法访问的功能。

Due to its quality and detail, the Bluesky Lidar data can also be used to provide accurate georeference for archaeological features – visible on historic aerial photography but not on more recent images. The data also has the potential to provide further insight into the historic landscapetHegarty等阶段诸如视野分析，如诸如视野分析的技术继续。

以前under-mapped

Bluesky捕获的三个地点位于东德文郡和Blackdown Hills Aonb，所有以前映射过的映射，但被认为是出色的考古潜力。LiDar的第一次横断术瞄准了黑阵山的西方围巾，该区域已知在罗马铁工业中一直很重要，局部划分的磨石开采。第二次研究领域是鹅卵石荒地的自然和文化上重要的景观，而从苏茅斯东北延伸到黑黑山的第三和最大的横断面，占据了A30的路线。

LIDAR调查是作为历史悠久的英格兰国家映射计划（NMP）的一部分进行的，用于识别，测绘和记录考古地点和来自航空照片的景观和其他远程感测数据的景观。考古调查是由历史环境咨询专家AC考古学进行的，并将新信息直接记录在德文县议会的历史环境记录（她）中。NMP方法和标准提供了专家空中口译员的手段，以将信息识别和记录到一致的标准，以提高对过去的土地利用的理解，并援助考古景观和古迹的识别和分析。
