Water is one of the vital sustaining components of all life. We as humans add to, subtract from, and interact with this dynamic, ever changing system on a regular basis. It’s important to maintain the health of the water system, especially where our impact is the most concentrated in areas that matter the most to humans: areas of high population.
Earth Imagery at Work
Occasionally I’m disheartened when I meet someone who isn’t familiar with the term massive open online course (MOOC). But then I realize that’s a teachable moment, and I explain what MOOCs are and why they’re relevant and valuable.
MOOCs matter to GIS professionals because they help generate that content but also because they enhance participants’ geospatial skillsets while adding substance to their resumes. That’s significant value, especially in the context of today’s flagging economy.
What’s a MOOC?
A MOOC is an online course offered by a company, university, non-profit, or other provider. MOOCs are typically open to large numbers of students and are nearly always free. Those with a fee typically have a “free option” that has fewer bells and whistles.
Show me my home! The human era of GIS begins
Little more than a decade ago, seemingly the whole world snapped awake to the power of imagery of the earth from above. We began by exploring a continuous, multiscale image map of the world provided online by Google and other mapping companies. A combination of satellite and aerial photography, these pictures of Earth helped us to experience the power of imagery, and people everywhere began to experience some of what GIS practitioners already knew. We immediately zoomed in on our neighborhoods and saw locational contexts for where we reside in the world. This emerging capability allowed us to see our local communities and neighborhoods through a marvelous new microscope. Eventually, naturally, we focused beyond that first local exploration to see anywhere in the world. What resulted was a whole new way to experience and think about the world.
Initially, we zoomed in on our homes and explored our neighborhoods through this new lens. This experience transformed how people everywhere began to more fully understand their place in the world. We immediately visited other places that we knew about. Today, we continue by traveling to faraway places we want to visit. Aerial photos provide a new context from the sky and have forever changed our human perspective. This map tour visits selected areas in several communities where ultra-high-resolution imagery is available.
These simple pictures captured people’s imagination, providing whole new perspectives, and inspired new possibilities. Today, virtually anyone with Internet access can zero in on their own neighborhood to see their day-to-day world in entirely new ways. In addition, people everywhere truly appreciate the power of combining all kinds of map layers with imagery for a richer, more significant understanding.
Almost overnight, everyone with access to a computer became a GIS user.
A range of applications
By now, it’s apparent that imagery enables whole new perspectives and insights into your world and the issues you want to address. Imagery also has numerous advantages and capabilities.
Almost daily access to new information
Image collection is rapid and increasing. And access to imagery is increasingly becoming more responsive. Many satellites and sensors are already deployed with more coming all the time, collecting new data, adding to a continuous collection effort—a time series of observations about our planet. These image collections are enabling us to map, measure, and monitor virtually everything on or near the earth’s surface. All of us can quite rapidly gather much of the data that we need for our work. Imagery has become our primary method for exploration when we “travel” to other planets and beyond. We send probes into space and receive returns primarily in the form of imagery that provides a continuous time series of information observations. And it enables us to derive new information in many interesting ways.
Looking back in time
The use of aerial imagery is still relatively young. While imagery only began to be used in the twentieth century, it is easy to compare observations for existing points in time that reside in our imagery collections. In addition, we can overlay imagery with historical maps, enabling us to compare the past with the present.
Imagery data collections are becoming richer every day
Imagery is creating an explosion of discovery. Many imagery initiatives are repetitive and growing, expanding and adding to image databases for our areas of interest. ArcGIS is scaling out, enabling the management of increasingly large, dynamically growing earth observations. This points to the immediacy of imagery and its capacity for easy integration, enabling all kinds of new applications and opportunities for use—things like before-and-after views for disaster response, rapid exploitation of newly collected imagery, image interpretation and classification, and the ability to derive intelligence. Over time, many of these techniques will grow in interesting new ways, enabling deeper learning about our communities, the problems and issues we face, and how we can use GIS to address these.
Imagery enables powerful analytic capabilities
Imagery and its general raster format enable rich analysis using ArcGIS. And, in turn, these enable more meaningful insights and perspectives about the problems we want to address.
This post is excerpted from The ArcGIS Imagery Book: New View, New Vision. Imagery is suddenly a big deal, and those who are adept at finding it, analyzing it, and understanding what it actually means are going to be in demand in the years ahead. The purpose of this book is to help everyone from GIS professionals to app developers, and web designers to virtually anyone how to become smarter, more skillful, and more powerful appliers of image data. The book is available through Amazon.com and other booksellers, and is also available at http://www.TheArcGISImageryBook.com for free.
The White House Initiative on Asian Americans and Pacific Islanders (WHIAAPI) will be celebrated on Friday, October 7, 2016. Earlier this year, the Department of Education and the University of California, Riverside launched the Elevate: AAPI Data Challenge, inviting the public to show new ways to analyze, interpret, and present data about Asian American and Pacific Islanders (AAPIs).
AAPIs are the fastest growing racial group in the USA, and the most diverse. Publicly available data sets include classification by national origin, such as Chinese, Filipino, Hmong, or Native Hawaiian and Other Pacific Islander. Quality of life may be enhanced for communities when they know about and participate in federal programs, so this challenge is one way to generate new insights.
At the March launch of the opportunity Project, White House Domestic Policy Council Director Cecilia Muñoz said Monday, “ZIP code should not determine destiny.”
Personally, this is why I chose to work in public service and then Esri, a forward-leaning organization that supports civic innovation and community solutions through smart mapping.
Maps can highlight the inequality we face as a nation today, and also provide a guide to resources and solutions that can help expand economic opportunity to every American, regardless of geography.
We at Esri were excited to participate in the second sprint of the Opportunity Project, because maps and spatial analysis offer real solutions to problems that every American faces. This second sprint has allowed us to work closely with subject matter experts to understand more completely how to design tools for communities participating.

Starting today Microsoft will be providing a public preview of a free, powerful, Esri-built mapping visual inside Microsoft Power BI. The new visual, ArcGIS Maps for Power BI, will provide a focused set of ArcGIS capabilities in both the cloud and desktop Power BI offerings. With ArcGIS Maps for Power BI you can do more with maps in your BI than ever before:
- Get your location data on the map in a snap using addresses, standard geographic boundaries (such as postal code, city, or state), or latitude and longitude values. Our industry leading geoenablement services have high accuracy and let you display your locations as points or boundaries (when possible).
- Get serious with map visualizations. Use the best map visualizations possible to make your case and tell your story.
- Make your maps easier to read with map themes such as heatmaps or clustering. In areas where you have many points on the map, aggregating the points helps you understand patterns at a glance.
- View your locations by size, color, or both. Visualize sales data by size while using color to show which sales rep owns the account to quickly identify the rock stars.
- Control the data classification used to display your points. You know your data, and you know how it should be displayed. Use common statistical classification methods such as natural breaks, equal interval, quantile, or standard deviation to show your data appropriately.
- Use reference layers to spatially analyze relationships in your data and complement your tabular analysis. A reference layer can help you understand what’s going on in the areas that are important to you. The boundaries of these areas can be used to select your Power BI data and filter the other charts and graphs in your reports and dashboards.
- Use a demographic reference map such as population growth, median household income, or median disposable income to identify interesting areas.
- Use community-submitted ArcGIS reference maps to go beyond the basic standard geographies offered in demographic reference maps. A world of community-shared maps is at your fingertips.
