Richard Leadbeater, State Government Industry Manager for Esri spoke with GISCafe Voice recently about Esri’s approach to smart cities and takeaways from the Smart Cities DC conference held in October. Leadbeater oversees all the state government stories and the area of smart space such as redistricting and elections.

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.
Among numerous announcements made this week at Intergeo in Stuttgart, Germany, by Trimble, the new Trimble X7 3D Laser Scanning System was introduced, a scanning system that enables professionals with little or no scanning expertise to capture precise 3D scanning data to produce high-quality deliverables.
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.
