Inland Water Mapping

Focus: Inland Water Mapping

Every month we will focus on a specific theme, featuring a selection of articles which have previously been published in Hydro International magazine. By including a mix of older and more recent articles, we will present a complete recap of the subject. Furthermore, we will be bringing you a bi-weekly round-up of ‘Focus Stories’ related to the theme through our newsletter (sign up here). The theme for September 2017 is:

Even when for inland water mapping the hydrographic techniques are familar, there are special requirements and challenges often due to the specific characteristics of inland survey and positioning. Often it's related to the reduced depth, accessibility or working space. This also creates opportunities to use techniques like airborne Lidar bathymetry or USVs.

Centralised Data for Hamburg Port Authority

The Port of Hamburg is the third-largest container port in Europe and among the biggest in the world. There are almost 300 berths with a total of 43 kilometres of quay servicing around 9,000 ships per year. The Hamburg Port Authority (HPA) is responsible for the ma... (read more)

Multi-purpose ENCs for Ports

Ports require access to a wide range of data and information to function safely and efficiently. Some of that data is acquired from external stakeholders but most is generated internally within the port. It is very often managed and held within a single software application,... (read more)

Riverbed Surveying

In order to meet the requirements of the European Water Framework Directive (EU-WFD), authorities face the problem of performing area-wide surveys of all kinds of inland waters repeatedly. Especially for mid-sized and small rivers, a traditional survey approach imposes almos... (read more)

IENCs in Flanders

Safety of navigation on inland waterways is as important as in maritime waters. To guarantee this, Electronic Navigational Charts (ENCs) have now been produced for several years. As inland waterways have specific features and regulations different from the maritime area, the... (read more)

Inland Water Mapping

Robust Data in Sensitive Environments

There are settings where an unmanned survey represents more than a safe, cost-effective alternative; it may be the only option. Capitol Lake in Olympia, WA, USA, is such a location. In this article, we report on a recent survey that highlights the advantages offered by an un... (read more)

Technology in Focus: Acoustic Doppler Current Profilers (ADCP)

Rather than a spinning propeller, the Acoustic Doppler Current Profiler (ADCP) – just like dolphins and bats – uses sound to explore its environment. Operating underwater, the method works like hand-held radars used by police to catch speeding motorists. This art... (read more)

When Bathymetry Determines Who Might Live and Who Might Die

The importance of bathymetry may be obvious to mariners, ocean modellers and marine geologists, but among the general public only the boating community seems to understand the importance of knowing water depths and the shape of the sea bottom. Most uses of bathymetry are not... (read more)

ALB Operations, Standards, Specifications and Stuff

In his column in 'Hydro International', Mark Sinclair from Fugro writes that he commends the ‘Technology in Focus: Bathymetric Lidar’ article; it is right on the money. Amongst other things, it describes the crucial factors leading to a successful... (read more)

Environmental Data Sharing and Publishing

The Port of London Authority (PLA) has had an extensive tide gauge network for many years. However, the existing system, installed in the 1990s was becoming increasingly unreliable providing inconsistent information due to a number of factors. There was a pressing need to de... (read more)

Surveying Japanese Inland and Coastal Waters

In March 2015, Leica Geosystems conducted a series of demonstration surveys in Japan with the HawkEye III Airborne Topographic Bathymetric Lidar system. This demonstration was designed to prove the depth performance and general capabilities of the HawkEye III system in... (read more)

Industry Brings Innovation to Inspire the New Generation

For the fifth year in a row, the Lake Survey was held in the Netherlands. This year Teledyne CARIS collaborated with Boskalis and Fugro in a one-week all-encompassing practical survey week. From 26 to 30 June 2017, 14 students worked with some of the most advanced equipment... (read more)

Lidar Bathymetry on the Alaskan North Slope

In June 2014, the Bureau of Economic Geology, a research unit at the University of Texas at Austin, was contracted to conduct an airborne bathymetric Lidar survey on the Alaskan North Slope. The purpose of the project was to further determine, understand, and map the local l... (read more)

Integrating UAS and Multibeam Echosounder Data

Knowing the volume of material present in a gravel quarry can make the difference between profit and loss. A gravel quarry in Hartheim am Rhein, southwest Germany, is partially covered by artificial lakes. To determine the volumes of the above-water gravel dumping grounds an... (read more)

Crowdsourcing Enhances Navigation Awareness

In this internet age, crowdsourcing is fast providing practical contributions to our understanding of the world around us. Whether it be software developed in an open-source environment, inputs from ‘those in the know’ to create and maintain wiki pages, or the pr... (read more)
