Snow Avalanches

Snow avalanches are one of the most hazardous winter phenomena that occur in mountainous areas. They are dangerous to human lives, especially in tourist areas used as ski resorts.
The Alps are the highest mountains in Europe. They are located across seven countries, but Switzerland is where the highest mountains ranges with the steepest slopes occur. On the scheme map and the pie chart below, we see that the Alps constitute a large part of Switzerland.

United Nations International Conference on Space-based Technologies for Disaster Risk Reduction - "Building Resilience through Integrated Applications" | UN-SPIDER Knowledge Portal | Everything is related to everything else | Scoop.it
The Office for Outer Space Affairs will host the 7th United Nations International Conference on "Space-based Technologies for Disaster Risk Reduction – Building Resilience through Integrated Applications Risk” in Beijing from 23 to 25 October 2017. The conference will be organised by the UN-SPIDER Beijing Office and follows six conferences held since 2011. Previous conferences covered the themes of “Best practices for risk reduction and rapid response mapping” in 2011, “Risk assessment in the context of global climate change” in 2012, “Disaster risk identification, assessment and monitoring” in 2013, “Multi-hazard disaster risk assessment” in 2014, “A consolidating role in the implementation of the Sendai Framework on Disaster Risk Reduction 2015-2030” in 2015 and “Understanding disaster risks” in 2016.

High-Res Satellites Want to Track Human Activity From Space

High-Res Satellites Want to Track Human Activity From Space | Everything is related to everything else | Scoop.it
Hopkinsville, Kentucky, is normally a mid-size town, home to 32,000 people and a big bowling ball manufacturer. But on August 21, its human density more than tripled, as around 100,000 people swarmed toward the total solar eclipse.

Hundreds of miles above the crowd, high-resolution satellites stared down, snapping images of the sprawl.

These satellites belong to a company called DigitalGlobe, and their cameras are sharp enough to capture a book on a coffee table. But at that high resolution, they can only image that book (or the Kentucky crowd) at most twice a day. And a lot can happen between brunch and dinner. So the Earth observation giant is building a new constellation of satellites to fill in the gaps in their chronology. When this new "WorldView Legion" sat-set is finished in 2021, DigitalGlobe will be able to image parts of the planet every 20 minutes, flashing by for photos dozens of times a day.

Getting started with GeoMesa using Geodocker | Everything is related to everything else | Scoop.it
In a previous post, I showed how to use docker to run a single application (GeoServer) in a container and connect to it from your local QGIS install. Today’s post is about running a whole bunch of containers that interact with each other. More specifically, I’m using the images provided by Geodocker. The Geodocker repository provides a setup containing Accumulo, GeoMesa, and GeoServer. If you are not familiar with GeoMesa yet

At Red Ventures, we partner with the nation’s top brands to seamlessly connect customers with the products and services they need most using our advanced digital marketing and sales capabilities. Along a customer’s journey, each interaction with Red Ventures presents an opportunity to make an influential decision: from the website creative they see to the time they spend waiting in a queue to speak to an agent. However, those decisions aren’t meaningful if they can’t use data and make a recommendation in real time. To that end, we have developed a machine learning platform that is constantly making decisions and is constantly learning to account for new data and trends.

New UN-GGIM strategic framework provides guidance for use of geospatial information and services in disaster risk management | UN-SPIDER Knowledge Portal

New UN-GGIM strategic framework provides guidance for use of geospatial information and services in disaster risk management | UN-SPIDER Knowledge Portal | Everything is related to everything else | Scoop.it
The Working Group on Geospatial Information and Services for Disasters (WG-GISD) of the United Nations Committee of Experts on Global Geospatial Information Management (UN-GGIM) has published a "Strategic Framework on Geospatial Information and Services for Disaster" to guide all stakeholders and partners in the management of geospatial information and services in all phases of disaster risk management.

The role of geospatial information has been widely recognized as an important aspect of all phases of disaster risk management (DRM). While calling on Member States to find solutions to improve availability and accessibility of geospatial information and services, the strategy document highlights the need for strengthening coordination and communication among stakeholders to ensure they are not collecting concurrent or inconsistent data.

GIS users come from every field : Geospatial Solutions

GIS users come from every field : Geospatial Solutions | Everything is related to everything else | Scoop.it
I just returned from the 38th Annual Esri International User Conference (Esri UC), which is the largest gathering of GIS (geographic information systems) professionals in the U.S. No GIS event in the U.S. is close to its scale.

Every year for the past 38 years (I presume, as I’ve only attended the last 11), Esri President Jack Dangermond begins by spending time during the kick-off plenary session painting his GIS vision. I appreciate that he doesn’t just dive into Esri-product-specific information. Granted, I know he’s setting the stage for that, but why wouldn’t he? He has a vision, and the products Esri develops will naturally follow that vision. Every year during his plenary presentation, I look for striking statements he makes.

Fast, optimized 'for' pixel loops with OpenCV and Python - PyImageSearch

Fast, optimized 'for' pixel loops with OpenCV and Python - PyImageSearch | Everything is related to everything else | Scoop.it
Have you ever had to loop over an image pixel-by-pixel using Python and OpenCV?

If so, you know that it’s a painfully slow operation even though images are internally represented by NumPy arrays.

So why is this? Why are individual pixel accesses in NumPy so slow?

You see, NumPy operations are implemented in C. This allows us to avoid the expensive overhead of Python loops. When using NumPy, it’s not uncommon to see performance gains by multiple orders of magnitude (as compared to standard Python lists). In general, if you can frame your problem as a vector operation using NumPy arrays, you’ll be able to benefit from the speed boosts.

Spatial Unmapped ~ GIS Lounge

Spatial Unmapped ~ GIS Lounge | Everything is related to everything else | Scoop.it
Geographic maps aren’t the only means by which to communicate spatial information.  These alternatives to communicating geographic information revise space so that a singular focal point emerges, unfettered by the standard depiction of spatial entities.

The Quasi-Map

Styles I like to refer to as quasi-maps are data visualizations that evoke geographic patterns but don’t adhere to absolute space (i.e. space marked by measurable distances).  Like cartograms, the geography of this type of spatial visualization has been disassembled to the extent where the geographic entity is only recognizable when viewed as a whole.
