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)

Web Mapping APIs

ESRI announces that its Web mapping APIs are available at no cost to users who are building applications for use in internal and noncommercial environments. ArcGIS Web mapping APIs have always been free for licensed ArcGIS Server users. Now government agencies, nongovernmental organisations (NGOs), and educational institutions can take full advantage of these mapping applications built on top of ArcGIS Server without additional costs or licensing.     Private businesses can also deploy these API-based applications internally for free.   ArcGIS Web mapping APIs are part of ESRI's Web infrastructure. Developers will have access to ArcGIS Online map services for... (read more)

Web Mapping for Education

The latest version of the EDINA Digimap service has gone live. The service is a co-operation of Cadcorp and the EDINA National Data Centre. Launched in 2000, the EDINA Digimap service specialises in the delivery of a number of geographical data resources over the Internet to over 150 academic institutions. National digital map data ranging from Ordnance Survey (OS) products to geology, marine and historical maps can be accessed by staff and students free at point of use. Based on Cadcorp's web mapping software GeognoSIS, the service also utilises a number of licences of Map Modeller, Cadcorp's desktop GIS.The new... (read more)

Mapping an Oil Pipeline

DEMs and Ortho-imagery for Colombia from Dual-band Side-looking Radar
Adverse weather and terrain conditions meant the Cano-Limon oil pipeline in Colombia had never been accurately mapped until orthorectified images and digital elevation models covering an area of 94,000km2 were created using airborne dual-band interferometric IFSAR simultaneously acquired X and P-band data. The authors report on main aspects of the project. The Cano-Limon oil pipeline extends nearly 780km from the Cano-Limon oilfield in Colombia’s Arauca region along the north-western border with Venezuela to a port in Covenas. When fully operational the pipeline can carry up to 20% of Colombian petroleum production, a major source of national revenue. In collaboration with... (read more)

NOAA Shoreline Mapping Contract

Photo Science (KY, USA) has been awarded a five-year IDC contract by the National Oceanic & Atmospheric Administration (NOAA) to provide aerial photography and photogrammetric mapping services to support of the nationwide Shoreline Mapping Program. Through this contract, Photo Science will assist NOAA in delineating approximately 95,000 miles of shoreline and provide an official and accurate delineation of the National Shoreline. This will be accomplished via stereo photogrammetry using tide-coordinated aerial photography controlled by kinematic GPS techniques. This process produces a seamless, digital database of the national shoreline and a database of aerial photography which will help establish the legal... (read more)

Underground Mobile Mapping

Laser Scanning and Imaging of Corridors in Japan
Common mobile mapping systems heavily rely on positioning using GNSS. However, concrete, soil and other materials block GNSS signals, thus impeding their use when inspecting pipelines, subways or other underground corridors. Furthermore, such corridors are often narrow, which requires the system to be compact. Here, the author describes a platform equipped with laser scanners and a camera which has been developed in Japan for mapping a wide variety of narrow underground spaces. Regular inspection of underground corridors is important to detect deformations and damage. The success of above-ground mobile mapping systems (MMSs) triggered us to design an MMS for use...
