黑匣子，全球机会和道德

Surveying is dead easy isn’t it? Of course it is, we did all that trigonometry stuff at school for GCSE. With that fantastic new Topocorp Trigo measurer we’ve just bought we can survey anything. Lovely job!

This has become a repeated worry for survey firms: the rise of cheap blackbox technology that encourages unqualified users to get started in survey. It’s only when our new user runs into surveys that don’t close and discovers things like scale factor, control or orthomosaics, that suddenly they need a bit more than GCSE Maths. A bit like Brexit in a way: easy to vote leave, rather more complicated to disentangle the complexity of rules and regulations for trade let alone projects planned or half way through.

Fortunately for would-be surveyors, there are a range of courses available from The Survey Association’s Survey School at Worcester. There’s even an apprenticeship scheme starting soon, which could lead after six or more years to full membership of RICS. This is excellent news for our industry. More details of this and the construction industry’s CSCS card scheme, which you’ll need if you’re planning a site visit any time soon, can be found from page 28.

Global Opportunities

该问题的GW将在Geo Business（5月23日至24日）发行；对于大多数地理学从业人员来说，它有很多关于世界银行土地与贫困会议的报告，这是测量师的真正见解。詹姆斯·卡瓦纳（James Kavanagh）在引用和介绍最相关的论文方面做得非常出色。土地转移，收购，地理空间信息，新技术，土地估值，税收，经济适用房，采矿和矿产权，性别问题和土著人民的土地权等。RIC清楚地看到了全球的机会，地理技能可以真正改变（开始第13页）。

We also examine aspects of BIM: how Bentley is migrating to the cloud and the gap between the data requirements of facilities managers and a BIM as prepared by the design and construction team. How do you geo-reference objects like, desks, printers, desktop PCs etc. planned for a room?

另一个复杂的挑战是如何在经济上衡量和记录平面表面的公差。比利时公司的减少与Tower Surveys联合提出了现有技术以衡量和记录铸造地板的水平的改编（第33页）。

Light detection and ranging continues to evolve and we look at the advantages that single photon Lidar brings to airborne scanning. Denser point clouds and faster capture rates are possible but at what point will SPL become a viable alternative to linear-mode systems? Turn to page 31.

道德挑战

Is it possible under all circumstances for a surveyor to act with integrity when work goes to the lowest bidder? Richard Groom examines the boundary between unethical and criminal behaviour and just when should you be prepared to walk away. The problems identified are all around us. I recently decided to change my broadband provider. Instantly the existing provider was offering all sorts of inducements for me to stay. The days when customers were rewarded for loyalty with better prices than the newby seem to have gone. How many times when shopping for an insurance quote have you been asked, ‘How much have you been quoted?’ Is this ethical? Shouldn’t they be quoting you honestly at their best possible price based on the risks? If tenderers for major projects were allowed to do this it would become a chaotic race to the bottom and could leave clients picking up the bill from failed contractors.

最后，不要错过Geo业务。我们在第22-27页上的评论仅赋予了商店中的内容。它有望比以前的事件更好。期待在5月23日或24日在伦敦与您见面。
