Avalanches can be extremely dangerous especially for off-piste skiers as well as for small towns situated below the slopes. As ski season comes upon us, it’s a good idea to check the avalanche conditions of the ski slopes you plan on frequenting. There are over 1000 avalanches occurring every year in the Swiss Alps alone. Local communities put up steel fence barriers along the slopes to prevent avalanches from encroaching near their town. To build such snow barriers, steep rock faces and cliffs need to be surveyed with utmost precision.

The FAA estimates that there will be nearly half a million registered commercial use drones in the U.S. by 2022 (FAA 2018 – 2038 Aerospace Forecast).
Drones, or UAVs or UAS, are being used in the GIS industry for such purposes as military surveillance, real estate, searching for hurricane activity, search and rescue missions, public health and safety, agriculture and in construction and countless other industries. In some cases, drones can provide greater resolution than satellite imagery. Their size and affordability makes them a valuable choice for scientists, power companies, surveyors, military actions and civilians and many others. They are also environmentally friendly and provide a low-cost option for gathering valuable data that can then be fed into a GIS.
Since drones can autonomously collect a vast range of data they are appealing to many use cases. Besides, they are light-weight and high performance. Satellite imagery has provided remote sensing data for mapping, but can often display low fidelity or limited visibility from cloud cover. High precision and accuracy can be achieved with aerial imagery, with planes equipped with high tech remote sensors. Photogrammetry, which makes use of overlapping photos to identify exact measurements between objects, is a useful way of gathering accurate models.
Dublin Airport is a busy international airport with very restricted airspace, which makes it difficult for an aerial survey company to capture data. As a consequence, the airport has been using data collected by laser scanning aircraft from aerial mapping company Bluesky to accurately measure land surface elevation to help reduce the risk of flooding at the airport. Dublin Airport is the 11th busiest airport in Europe, serving more than 31.5 million passengers in 2018, travelling to almost 200 destinations in 43 countries.
This week, GISCafe Voice spoke with Este Geraghty, MD, MS, MPH, GISP, Chief Medical Officer & Health Solutions Director, Esri. Formerly the Deputy Director of the Center for Health Statistics and Informatics with the California Department of Public Health, Dr. Geraghty led the state vital records and public health informatics programs. There she engaged in statewide initiatives in meaningful use, health information exchange, open data and interoperability.
At the GEOINT Symposium 2019 held in San Antonio, Texas, NGA Director Vice Adm. Robert Sharp gave a keynote in which he brought to the audience’s attention new leadership roles including his own as the seventh NGA director.
In an interview with Arnaud de Saint Vincent, Analytics Strategy – Digital Services Intelligence Communications, Intelligence, Security of the Defence and Space intelligence branch of Airbus, he spoke about one of their digital services, Earth Monitor, under the umbrella of their OneAtlas platform. Airbus Defence and Space and Orbital Insight have expanded upon their partnership agreement to create Earth Monitor, a powerful change analysis and insights service which provides situational awareness over archived or newly tasked areas of interest.
The Notre Dame Cathedral has been well-documented both before and after a devastating fire destroyed its spire and roof on Monday, April 15, 2019. What we have going forward is extensive documentation in the forms of satellite imagery, aerial imagery, as well as 3D laser scans to help in the reconstruction of the Gothic cathedral.
