Mangrove Mapping and Monitoring

RS and GIS in Conservation and Management Planning
The mangroves of the Sunderban area in India are one of the most productive and diverse ecosystems in the world, and yet they are a threatened habitat. To formulate a conservation and management plan periodic mapping and monitoring of mangroves is a prime requisite. The authors demonstrate that remote sensing and GIS techniques, including visual interpretation, are effective and efficient techniques for this purpose. The objectives of this study are threefold: mangrove mapping and monitoring, database creation and conservation prioritisation. Essential parameters in monitoring mangrove areas are disturbance index and fragmentation level. The disturbance index provides a measure for the... (read more)

Danish Aerial Mapping Company

As part of Fugro's strategy to expand its Aerial Mapping services business in Europe, a new company - Fugro Aerial Mapping A/S - has been established in Denmark to provide Aerial Imagery and LiDAR services in Scandinavia.   Fugro acquired earlier this summer three survey aircraft, various sensors and other related equipment which were formerly owned by the company Scankort A/S and which will be operated in future by the new Fugro company in Denmark.   (read more)

INS for Airborne Mapping

iXBlue, France, has presented ATLANS as a cost-effective georeferencing and orientation system, designed for land and airborne mapping applications. The user obtains a compact, lightweight gyrocompass and motion sensor that consumes little power and yet provides all of the required data for demanding navigation, stabilisation and control applications as in UAS, digital imaging and hyperspectral imaging applications. ATLANS can be easily integrated with standard GNSS and DMI systems and is combined with most commonly used flight management, satellite tracking and mobile imaging systems. All of the interface and computing electronics are contained within a single housing that also features an... (read more)

GGP's FastMAP Field Mapping

GGP Systems (UK) has announced a GPS and laser-assisted field mapping system for creating accurate maps of public-owned property, land and assets. The development follows integration between GGP's GIS and FastMAP, the mobile GIS Data Collection software from the Korec Group. Rugged handheld PC's are used in the field to map features, collect asset information and report incidents, aided by GPS satellite positioning and laser rangefinder instruments that allow pinpoint-accurate mapping including heights. The positioning technologies accurately record the position of an asset or feature against the on screen map display, which is compatible with Ordnance Survey MasterMap, and this... (read more)

Satellite Imagery for Mapping

The ICA Commission on Mapping from Satellite Imagery is responsible for educating and informing the geospatial- data handling community about the link between the raw data captured from satellite imagery and the extraction, presentation and application of information derived from such data. See previous report on this page, GIM March 2007. ToR The Terms of Reference of the 2007-2011 commission, approved at the Moscow ICC, August 2007, include fundamental work: “[…] analysis of existing and forthcoming satellite imagery in view of their potential inputs for producing and updating topographic and thematic maps and databases; and assessment of the cartographic capabilities...

Mapping from Satellite Imagery

The emergence of new, low-cost, internet-based mapping tools like Google Earth, Google Maps, and NASA World Wind that make thousands of satellite images available to a wide audience has greatly influenced perception and awareness. This goes for both the general public and the scientific community, who now see the enormous potential of mapping from satellite imagery. Such tools highlight the crucial role of remote sensing in providing fast, up-to-date cartographic information for informed decision making, particularly for rapid mapping of pre- and post-disaster events, emergency planning, geomarketing, or even simpler activities like planning a holiday trip. The ICA Commission on... (read more)

Hazard Mapping and GIS

Simulating Avalanche, Debris Flow and Rock-fall
The extreme avalanche winters of 1951 and 1999 in Switzerland clearly demonstrated the need for hazard mapping in mountainous areas. Hazard mapping helps in devising mitigation measures such as the construction of natural and artificial protection against avalanches, debris flow and rock-fall. The authors developed a new system called RAMMS (Rapid Mass Movements) comprising avalanche, debris-flow and rock-fall, protect and visualisation modules linked to a GIS.<P> Nets provide one example of an artificial protection against rock-fall. Natural protection is afforded by stands of forest on mountain slopes. Knowing how trees dissipate energy, by for example either the trunk or root... (read more)

Mapping the World

GIM International Interviews Steve Coast
Steve Coast founded OpenStreetMap in 2004. It's a free, editable map of the world which has been made by people across the globe and allows users to view, edit and use geographical data in a collaborative way from anywhere on the planet. GIM International spoke to him about the project and what lies ahead.   What motivated you to start an ‘open' street map? Back in 2004, Wikipedia had become an extremely successful project and I thought it would be a good idea to apply the same principles to the creation of maps of local areas around the globe. By...

Rwanda Pioneers UAV Mapping

After Rwanda made waves in the news early last year for allegedly being the first country to approve drone-based deliveries, people started paying attention. The country, with its rolling hills and one of the fastest-growing economies in Central Africa, has already established regulations regarding drones and become a vanguard of sorts for the region. To support this development, in 2016 the University of Twente organised a course in Rwanda on the latest drone mapping techniques. There is a huge market in Africa at the moment, according to Francesco Nex, assistant professor at the ITC Faculty, University of Twente. The country is growing very fast, with... (read more)

Mapping Flood Vulnerability

Deriving Risk Indicators from Open Data
Floods have a high impact in densely populated areas, especially when strategic infrastructure is affected. There are various human and territorial factors that influence an area’s vulnerability to flooding. Intensive agricultural activity and large urbanised areas are examples of such human factors, while the soil’s ability to absorb water is a major territorial factor. A quantification of flood vulnerability can be created by combining numerical indicators for the various factors into a single index number that is easy to interpret for decision-makers. GIS tools can easily be applied to calculate these indicators from various open spatial data sources, offering a... (read more)
