从上方克服

作者：本杰明·费德曼（Benjamin Federmann），2016年6月

With only 18 per cent of the country’s population living in urban centres, Papa New Guinea is one of the world’s most rural and unexplored countries. Dense with rainforest and other diverse ecological features, terrain is a constant obstacle for surveyors. Restricting access to key areas, measurement professionals must find innovative means to gather needed data.

当Porgera矿山调查小组签约澳大利亚北部昆士兰州的一家调查公司Benchmark Survey＆Design时，在高地Porgera Valley的头部隔离地面上，高地的高度为2,200至2,700米，在高地的Porgera山谷头上绘制溢出地面。专门从事地形站点调查的公司知道需要找到一种新的测量方法。由于捕获的数据将用于环境监视矿山产生的溢出物的转储站点，因此准确性至关重要。

Mapping dangerous terrain with an UAV

在山体滑坡和地震很常见的地区，只有五天可供映射，基准调查和设计确定了通过空中调查是最安全，最快的调查方法。该公司转向了在GIS工作20多年的澳大利亚公司空间技术，以提供无人机飞行员。飞行aibotix aibot x6在过去两年中，空间技术在过去两年中在各种环境中收集数据。

With two sites to capture around the mine, Anjolek at 380 hectares and Anawe at 250 ha, the pilot, Anton van Wyk, had to carefully plan his route. Facing several challenges, such as much of the terrain only accessible by helicopter, use of the helicopter only available one out of the five days to map, and extreme weather with fog in the mornings and rain in the afternoon leaving only a few hours each day to survey, van Wyk’s precise plan rested upon the durability and dependability of theaibot x6。

“这aibot x6即使在如此崎rough的地形中，也提供了比Porgera矿山调查团队所期望的更好的结果。“尽管矿山调查团队在此任务之前曾有过此任务，但该团队没有收到数据的专家映射和处理数据aibot x6delivered with its more advanced sensors.”

With 32 total flights at about 10 minutes each, Spatial Technologies collected 9,100 orthophotos at a 5 cm ground sampling distance. While Benchmark Survey & Design only need sub-metre accuracy for the project, Spatial Technologies was actually able to supply 10-20 cm accuracy with strategically placed controls in conjunction with the RTK on the Aibot X6. The entire project was processed in about 96 hours to provide visual documentation of volume changes in the spill grounds.
