Alaska Revealed

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.

Important 3D Terminology

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.

This scene shows the global pattern of airports and the interconnected air traffic routes using the openflights.org data.

Mapping the Third Dimension

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.

Some stories lend themselves very well to 3D storytelling. The Mountains of Fire story map is composed of a number of 3D web scenes.

The Art of Mapmaking

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.

Swisstopo is the official name for the Swiss Federal Office of Topography, Switzerland’s national mapping agency. With all the mountains in Switzerland, it should be no surprise that they developed many of the classic cartographic techniques, like the Swiss Hillshade.

The ArcGIS Imagery Book: A Geographic Rosetta Stone

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.”

New Orleans at Esri UC – a Behind the Scenes Look and Repeatable Solutions

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.
