WingtraOne and Septentrio GNSS Receivers Team Up to Provide 3D Positioning Accuracy for Avalanche PreventionThursday, November 7th, 2019
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.
Each year at the Bentley Year In Infrastructure thought leadership conference brings a new dimension to digital workflows. Digital Twins were definitely the order of the day this year, and mobile mapping and some other technologies taking front and center stage in the form of acquisitions.
In September, CoreLogic released their 2019 Wildfire Risk Report that analyzes the top regions, states and metro areas at risk for wildfire damage, including number of at-risk homes and their estimated reconstruction costs. The report also includes a breakdown of 2017 and 2018’s major wildfires, which were quite extensive through the western United States. The report focuses on homes in the western states including Arizona, California, Colorado, Idaho, Montana, New Mexico, Nevada, Oklahoma, Oregon, Texas, Utah, Washington and Wyoming.
Some important facts from the report include (from company materials):
- The report found nearly 776,000 homes with an associated reconstruction cost value of more than $221 billion are at extreme risk of wildfire damage.
- The Los Angeles, Riverside and San Diego metro areas ranked as the top three high-risk areas, respectively with more than 42% of residences at high-to-extreme wildfire risk.
- These regions make up more than 51% of the total RCV of the top 15 metro areas analyzed.
- In 2018, the highest number of acreage burn occurred in California (1,823,153 acres burned), Nevada (1,001,966 acres burned) and Oregon (897,262 acres burned).
- 2018 was a record-breaking wildfire year with 8,767,492 acres burned—roughly equivalent to 74 of the 75 largest cities in the United States combined.
- This marked the 6th highest total since modern historical records began in the mid-1900s.
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.
David Smith, Senior Director Model Development at CoreLogic, spoke with GISCafe Voice about CoreLogic’s recent announcement of residential and commercial flood and wind loss estimates for Hurricane Barry before the event occurred. According to this data analysis from the company, flood loss for residential and commercial properties in Louisiana is estimated to be between $200 million and $400 million which includes both storm surge and inland flooding. Insured flood loss from private insurers is estimated at less than $100 million. Wind losses are estimated to be an additional $300 million to $500 million. In total, insured flood and wind losses, excluding National Flood Insurance Program (NFIP) losses, are between $300 million and $600 million.
