Exciting news from the Arctic! Version 2 of the Arctic DEM has been released. Topographic elevation of the Arctic can now be viewed and analyzed like never before. This release extends the detailed 2 meter Alaska elevation data with additional 2m data for Novaya Zemlya and Franz Josef Land, as well as preliminary 8 meter data for the entire Arctic. Additional detailed 2 meter elevation data will be released in quarterly installments over 2017 until the arctic data is complete. This is the result of a partnership between Esri, the National Geospatial Intelligence Agency, the National Science Foundation, and the Polar Geospatial Center at the University of Minnesota.
In September 2016, the White House hosted an Arctic Ministerial meeting, with over 20 countries represented, where this data was showcased and new commitments on data provisions were sought. The goal of the meeting and the function of the new data is to help people better understand, adapt to, and address the changing conditions in the Arctic.
The four key themes include:
- Understanding Arctic-Science Challenges and their Regional and Global Implications.
- Strengthening and Integrating Arctic Observations and Data Sharing.
- Applying Expanded Scientific Understanding of the Arctic to Build Regional Resilience and Shape Global Responses.
- Using Arctic Science as a Vehicle for Science, Technology, Engineering, and Math (STEM) Education and Citizen Empowerment.
Esri Joins ASPRS UAS Mapping Symposium as Keynote Speaker and Exhibitor ― Sharing How Drones are Changing the Face of Remote Sensing
The annual UAS Mapping Symposium is one of the nation’s leading conferences on drones, bringing together geospatial experts from across the country. The symposium is organized by the American Society of Photogrammetry and Remote Sensing, the premier imaging and geospatial information society.
As the world’s leading provider of GIS technology worldwide, my Esri colleagues and I are pleased to join ASPRS for this special opportunity to educate and inspire UAS industry professionals. My keynote session, “The Illusion of Simplicity: The Case for Making Drones Easy to Use”, will explore gaining the geospatial advantage by solving application-specific problems using imagery-derived information from UAS systems. I will share recent examples illustrating several use cases, along with observations on near-term trends related to drone use within GIS systems.
Getting the z-terminology straight
Maps and Scenes
GIS content can be displayed in 2D or 3D views, and there are a lot of similarities between the two modes. For example, both contain GIS layers, both have spatial references, and both support GIS operations such as selection, analysis, and editing.
However, there are also many differences. At the layer level, telephone poles might be shown in 2D as brown circles, while the same content in 3D could be shown as volumetric models—complete with cross members and even wires—that have been sized and rotated into place. At the scene level, there are properties that wouldn’t make sense in 2D, such as the need for a ground surface mesh, the existence of an illumination source, and atmospheric effects such as fog.
A Change in Perspective
3D is how we see the world. With 3D Web GIS, you bring an extra dimension into the picture. See your data in its true perspective in remarkable photorealistic detail, or use 3D symbols to communicate quantitative data in imaginative ways, creating better understanding and bringing visual insight to tricky problems.
The Evolution of 3D Mapping
Throughout history, geographic information has been authored and presented in the form of two-dimensional maps on the best available flat surface of the era—scrawled in the dirt, on animal skins and cave walls, hand-drawn on parchment, then onto mechanically printed paper, and finally onto computer screens in all their current shapes and sizes. Regardless of the delivery system, the result has been a consistently flat representation of the world. These 2D maps were (and still are) quite useful for many purposes, such as finding your way in an unfamiliar city or determining legal boundaries, but they’re restricted by their top-down view of the world.
ArcGIS for Cartographers
The ArcGIS platform provides capabilities that enable everyone to make truly excellent maps, including support for highly sophisticated mapping workflows employed by professional cartographers. Desktop includes tools for rich data compilation, for importing data from a multitude of publication formats, and for integrating this data with your own data to create consistent, accurate, and beautiful cartographic products for both printed maps and online maps.
Imagery is Visible Intelligence
By: Dave Grenley
The next generation of imagery intelligence comes alive in The ArcGIS Imagery Book: New View. New Vision., published by Esri Press. It is now available in print, interactive PDF, and interactive companion website.
The new book provides readers with a wealth of gorgeous, inspiring images and links to powerful web apps and maps that weave interesting stories about our planet and the issues we face. Readers will also gain foundational knowledge about how imagery and remote sensing is used for geographic information system (GIS) technology.
The ArcGIS Imagery Book offers a look back at the fascinating history and rapid evolution of earth observation technology. Readers will learn about modern earth imaging technologies and how imagery data can be used in GIS—for real world applications such as asset management, precision agriculture, emergency response, real estate geolocation, urban planning, natural disaster assessment, and climate studies.
Additionally, readers will gain hands-on experience working with powerful imagery and remote-sensing data through the book’s companion lesson plan from the Learn ArcGIS organization.
The book’s editors, Clint Brown, Esri director of software products, and Christian Harder, Esri senior editor and writer, said they hope the book will help turn readers into “GIS and imagery aces.”
The ArcGIS Imagery Book is the second in a series of publications from Esri (following The ArcGIS Book) that provides an online interactive learning experience for readers to take advantage of, at their own pace. “It comes with intelligent information items: maps, web scenes, analytic models, story maps—just amazing rich content,” said Brown. “We get into real-world problem solving and real-world applications.”
This year the City of New Orleans showcased their great work at the Esri User Conference Plenary. A major theme of their presentation was citizen engagement and creating a real two-way engagement enabling citizens to take in civic responsibility. New Orleans is doing outstanding work, and all of the solutions are configurations that can be repeated for any local government.
The first demonstration was the Property Survey solution in which we have enlisted User Conference attendees to help survey their properties for blight at https://propertysurvey.nola.gov/photosurvey/ This solution can be useful for a variety of applications such as code enforcement, emergency management assessment or tax appraisers. The Photo Survey Solution from the Esri Solutions gallery will allow you to process geo-tagged photos and an application to set up randomized surveys as New Orleans has done. Since 16,000 UC attendees were enlisted to help assess properties and shared on social media, Esri Managed Services was used to make sure the underlying infrastructure was ready for reliability and scalability.
I had the pleasure of being part of the team representing Esri at the American Planning Association (APA) National Planning Conference in Phoenix, AZ (see a picture of the Phoenix Convention Center below). I really feel at home among planners, as I have a Masters degree in Urban & Regional Planning, attained the American Institute of Certified Planners (AICP) certification, spent part of my career as a Planner, as well as worked with planners as a GIS practitioner.
The world is going through some serious changes right now. If you ask city officials what keeps them up at night, the majority of them will say jobs, followed by water scarcity, flooding, traffic congestion and failing infrastructure. For many, it’s the loss of millennials to big cities, or the aging of their population.
More than 4,800 people gathered at the 2016 Esri Federal GIS (FedGIS) Conference to share how government agencies are innovating with GIS. Attendees and speakers talked about making data more accessible and actionable, collecting imagery with drones, and expanding use of cloud technology and mobile apps to more seamlessly execute their missions and better serve their end users.
Keynote speaker and National Geospatial Intelligence Agency (NGA) Deputy Director Sue Gordon shared how NGA is opening non-classified data, including making digital elevation models available, to the public for the first time. Like many federal agencies, NGA is increasingly implementing in a cloud environment and using mobile apps to enhance resource sharing. Doing so supports missions and will support safety at events like the upcoming 2016 Olympics in Rio de Janeiro.
Across the more than 125 sessions, users demonstrated how GIS is providing the framework for applying geography to critical decision making. Here are the top four takeaways you should know: Continue reading
