Size and Height are Relative but could Eagles Dare?

With important upcoming events for our profession, Gordon Johnston reflects on the global market for spatial data, height reference frames (both personal and established) and a novel potential survey platform.

I’ll take this opportunity to declare my interest in the coastal and offshore sectors of our profession, an area which is growing in importance with an increasing awareness across the media and the public of the potential benefits and opportunities that responsible sustainable development of our seas could offer. The terms Blue Economy, Blue Growth and Blue Horizon all link to this strategic concept of beneficial development of our seas.

为了衡量该行业如何胜任，抑郁症油气价格对新技术和自动化系统的影响冲突，我将在3月份访问伦敦Excel的海洋学国际，见www.oceanologiceinternational.com/。世界各地的海上石油部门的城市被努力打击资本支出和运营项目的减少，从而对人民的生活造成损失。此类事件非常重要，因为这是这一重要地理空间部门的创新，灵活性和多样性，这些行业从这些周期性下滑的最严重的影响中消除了我们。

虽然海洋部门正在经历一些真正粗糙的补丁，但很明显许多基于陆地的活动继续发展和扩展。一种这样的自动化 - 空间数据的收集，处理，分析和管理中的常量主题。自动化导致机器人，因此我读到了通过使用它们来抓住或破坏远程试点的空中系统（RPA或许多简单，无人机）来评估训练有素的老鹰乐队的消息。虽然几乎每个电视频道的新闻计划定期设法包括从无人机的镜头，但在拥挤的地区的规定和使用时越来越担心。也许替代方案是将老鹰用作调查的平台。

我有许多同事，分裂意见量化了地理空间市场的规模。所以我想不应该令人惊讶的是，发现美国的一项研究发现，山坡的尺寸，陡峭，爬升或高度的评估是受个人的个人状况和健身的影响。较大的人似乎看到并判断了比一个小人更大的东西。这可能是一个户外现象，因为我不相信它在室内抱着真正的堂兄（2.03米或6英尺8英寸）在进入每个房间时都必须鸭，并抱怨小床。所以当谈到身高时，事情通常是相对的和主观性......也是许多其他测量。这就是为什么要采用和维护标准的一致性和重复性。

Talking of height... vertical things are on the up! Sorry, that was a bit too obvious but it is a topic that appears, after many years, to be getting a broader and more engaged audience with some serious groups generating new guidelines and actively promoting its relevance. The Vertical Offshore Reference Frame (VORF) was developed in the UK to assist in resolving the vertical dimension. Across the North Sea, the EU’s BLAST project provides “harmonized” data across the land and sea interface, with the main challenge being the vertical. Elsewhere, NOAA has the VDatum online tool and Australia has the AusGeoid09 model. These initiatives are important but it would be beneficial if users could rely upon a consistent and standard approach to how these models are described, accessed and supplied. The importance of standards and good practice guidance for professional users is key. Look out for work being completed by the IOGP (International Oil & Gas Producers) Geomatics division to assist users interested in this dimension.

As this edition of GW goes to press the third of ESA’s Sentinel satellites has been launched. With three land and ocean observation satellites, providing high quality hyper-spectral data, the opportunities to use and benefit from these initiatives is tremendous, especially considering the data is free for most users.

展望未来有许多即将推广和提高我们对更广泛的社区职业的认识。5月初（2-6）无花果持有其年度工作周，今年在基督城新西兰，其中一个毁灭性地震挑战了许多生活和工作的人。无花果社区是一个强大的一个，海外游客将能够为自己的影响和决心恢复到昔日的荣耀。图的主题是“从灾难中恢复”强调空间数据对社区空间的规划和可持续管理的关键重要性，是城市，农村或沿海海洋地区。看：www.fig.net/fig2016

Later in May (24-25) is GEO Business in London, a showcase for the geospatial industries and profession, which is again set to break records. It offers the chance to hear experts present the latest developments and to meet and network with companies and fellow professionals. See:http://geobusinessshow.com
