Overcoming from above

爸爸新几内亚只有该国只有18％的人口居住在城市中心，是世界上最农村和未探索的国家之一。雨林和其他多样化的生态特征，地形是测量师的持续障碍。限制进入关键领域的访问，测量专业人员必须找到创新的手段来收集所需的数据。

When Benchmark Survey & Design, a survey firm in North Queensland, Australia, was contracted by the Porgera Mine Survey Team to map spill grounds around the secluded mine located at the head of the Porgera Valley in highlands at an altitude of 2,200 to 2,700 metres, the firm specialising in topographic site surveys knew it needed to find a new method of surveying. As the captured data would be used to environmentally monitor the dump sites of the spill generated by the mine, accuracy was of the utmost importance.

用无人机绘制危险的地形

In an area where landslides and earthquakes are common and with only five days available to map, Benchmark Survey & Design determined a survey by air would be the safest and quickest survey method. The firm turned to Spatial Technologies, an Australian firm with more than 20 years in GIS, to provide an UAV pilot. Flying theAibotix Aibot X6UAV and collecting data in various environments for the past two years, Spatial Technologies was up for the challenge.

在矿山周围捕获两个地点，安乔尔克（Anjolek）的380公顷和250公顷的阿纳维（Anawe），飞行员安东·范·威克（Anton Van Wyk）必须仔细地计划他的路线。面临几个挑战，例如直升机只能访问的许多地形，直升机只能使用五天中的一个可用的地形，以及下午的早晨和雨中的极端天气，每天只剩下几个小时to survey, van Wyk’s precise plan rested upon the durability and dependability of theAibot X6.

“TheAibot X6provided better results than what Porgera Mine Survey Team expected, even in such rough terrain,” said Wayne Storey from Benchmark Survey & Design. “Though the mine survey team had someone prior fly this mission, the team didn’t receive the expert mapping and processing of the data theAibot X6带有更高级的传感器。”

每次约10分钟的总飞行总数为32个，空间技术在5 cm的接地采样距离处收集了9,100个正射。尽管基准测量和设计仅需要该项目的子量表精度，但空间技术实际上可以通过策略性放置的控件与AIBOT X6上的RTK一起提供10-20厘米的精度。整个项目在大约96小时内进行了处理，以提供溢出场中体积变化的视觉文档。
