Californian Seafloor Mapping Reveals Hidden Treasures

Three products in an ongoing series have been released by the U.S. Geological Survey: a map set for the area offshore of Carpinteria, California, USA, a catalogue of data layers for geographic information systems, and a collection of videos and photos of the seafloor in state waters along the entire Californian shoreline. They contain new imagery, new and specialised undersea maps as well as more data. The USGS is a key partner in the California Seafloor Mapping Program, a historically ambitious collaboration between state and federal agencies, academia, and the private sector to create a comprehensive base-map series for all...

Hydrological Surveying and Mapping Forbidden in China

Hydrological monitoring and mapping will not be allowed in China and hydrological organizations are now expected to strengthen their monitoring of changes in water flow and quality that could potentially threaten the security of water use. The State Council regulation also states that hydrological forecasts should only be released to the public by relevant government departments or authorised hydrological organisations, other organisations and individuals are not allowed to release the information. Organizations and individuals that flout the new law and conduct hydrological activities without authorisation will be fined 50,000 to 100,000 yuan (US$6,500 to 13,000), according to the regulation. China... (read more)

Analysis of CZMIL and Coastal Mapping Technology

A current user of the Teledyne Optech CZMIL Coastal Zone Mapping and Imaging Lidar will make a presentation , comparing various Lidar bathymeters during Shallow Survey 2015, to be held at Plymouth University, UK, from 14-18 September. The presentation ‘A look into the performance of bathymetric Lidar systems’ given by Chris Macon of the Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX) is scheduled at 10:15 on Wednesday, 16 September. JALBTCX spent the summer testing several types of bathymetric Lidar sensors and Mr. Macon will discuss their results. Depth up to 65m The Teledyne Optech booth M14 will have... (read more)

SonarWiz 5 Sonar Mapping Software Accelerated

Chesapeake Technology (USA) has released an updated version of its flagship product, SonarWiz 5. In response to customer feedback, new features were designed to speed up mission planning, target prosecution and change detection.     A new survey-line pattern option that is used when filling closed polygons simplifies the setup of survey lines in complex geographic areas. This feature was also added to the office-based product so that more users can get involved in the survey planning process.   The new target-location function survey-line feature generates a four-line search set at a user-specified range and length centred on a target...

Interactive Marine Mapping Data Product Demonstrators

OceanWise, UK, has released free, interactive Marine Mapping product demonstrators. Built using OpenLayers, the demos allow the user to pan around a defined area and get a feel for different data products. The online services can be used through a web mapping interface or direct to the user’s desktop GIS, thereby removing the headache of holding data and the need for updates. The objective of the demos is to better help businesses make more informed decisions on the purchase of data and also improve the business case for adoption of web services by making the argument easier and more compelling....

SeaZone Launches Coastline Mapping Improvement Programme

SeaZone Solutions has completed the first pilot area as part of its ongoing Coastline Mapping Improvement Programme (CMIP). This is set to change the understanding of the relationship between land and sea. Using CMIP will resolve the serious inconsistencies arising from coastline data that is generated in different ways by the United Kingdom Hydrographic Office (UKHO) and Ordnance Survey (OS) Great Britain. The UKHO and OS have, since the 18th century, independently created their own datasets using different methods, policies and techniques and ultimately for different purposes. Using CMIP will make it possible to deliver marine data that is completely... (read more)

Citizen Mapping and Charting (Part 1)

The Concept of Crowdsourcing and Its Applications
Since the dawn of time people have been making maps. Such mapping was initially done by anyone and everyone. Eventually mapping became the domain of skilled map makers. Then technology changed the game. GPS, digital cameras and broadband internet arrived, and now many successful environmental mapping projects are largely carried out by volunteers, a variation of the phenomenon now known as crowdsourcing. The pace of volunteered geographical information (also known as Citizen Mapping) goes on with or without the involvement of mapping agencies. But what about Citizen Charting? And how may hydrographic organisations be enticed to get involved and help... (read more)

Coastal Mapping Technology at Coastal GeoTools 2015

Optech will show its marine mapping solutions at the Coastal GeoTools 2015 conference taking place 30 March to 2 April in North Charleston, South Carolina, USA. Visitors to the Optech stand will learn how they can generate bottom 3D topo/bathy information for coastal zones, especially in turbid and muddy water conditions with the powerful new CZMIL Nova. This smaller, lighter, lower-power consumption model leverages new laser advances and operates more efficiently with simplified maintenance, but still delivers data up to 80 metres deep in clear conditions and penetrates further than any other system in challenging waters. Besides a 58% reduction... (read more)

Mapping Seabed in and Around Ireland

The inshore waters of Ireland are areas of enormous activity and value. Yet more still needs to be learned about the physical, chemical and biological makeup of the seabed to ensure that effective resource management supports present and future economic and environmental issues. MacArtney supplied sonar equipment is mapping the seabed both in and around Ireland onboard the newly inaugurated vessel, the Keary, and onboard the Celtic Explorer.  Ireland’s inshore water areas are an enormous source of income and activity. Such high activity needs to be carefully measured and monitored to ensure the long-term viability of this valuable asset. The... (read more)
