By Patrick TuckerA little-known California company called Esri offers a “Facebook for Maps” that promises to change the way we interact with our environment, predict behavior, and make decisions in the decades ahead.
The setting is central California’s Yosemite National Park. A hiker, let’s call him Steve Clark, has gone missing on one of the trails. As the head park ranger, your job is to lead a search-and-rescue mission to find him. All you have to go on is the point where he was last seen, your training, and a computer; from this, you have to predict the behavior of a lost hiker. Sunset is approaching, and in some parts of the park the temperature will be below freezing in a matter of hours. What do you do?
Many experienced hikers know that the recommended course of action when lost is to follow a stream downhill and this will eventually lead to civilization. But you can’t assume that Steve Clark is aware of this, or that he’s even seen the Discovery Channel. He might elect to stay put, or, if he has a cell phone, he might be movinguphill to find a signal. You also don’t know if he’s injured. A person with a sprained ankle is less likely to walk up, but he may not move down, either.
Unlocking the Full Potential of GIS across Your Organization
Most of us using GIS take advantage of only a fraction of the capabilities, and over time we get comfortable in what we know and do. While this allows us to improve our work and optimize our processes, it also limits our impact across the organization. But expanding the scope of your GIS is a lot of work. At least it used to be.
Enter ArcGIS Solutions. Now you don’t need to dedicate significant resources and learn new areas from the ground up. We are committed to providing you easy to use apps, maps, and platform configurations to base your work on.

Spatial analysis has always been a hallmark of GIS, the “numerical recipes” which set GIS apart from other forms of computerized visualization and information management. With GIS we pose questions and derive results using a wide array of analytical tools to help us understand and compare places, determine how places are related, find the best locations and paths, detect and quantify patterns, and even to make spatial predictions.
As Chris Cappelli duly notes: “The greatest potential for change and success occurs when we all understand and speak the same language—the language of spatial analysis.” And what better way to speak that language than by way of a story map? As people continue to explore and share their world using the medium of story maps, some are venturing beyond the simple map tour mode of points linked to photographs, toward “stories” that examine, explore, and showcase the results of a spatial analysis. We’ll likely see more of these analytical stories as the story map medium is introduced into more GIS courses, particularly at the university level.
Here is small catalog of analytical story maps. Please come visit again as I will try to add to this page throughout the year!
We use high quality climate data from ground meteorological stations in the Iberian Peninsula (IP) and robust drought indices to confirm that drought severity has increased in the past five decades, as a consequence of greater atmospheric evaporative demand resulting from temperature rise. Increased drought severity is independent of the model used to quantify the reference evapotranspiration. We have also focused on drought impacts to drought-sensitive systems, such as river discharge, by analyzing streamflow data for 287 rivers in the IP, and found that hydrological drought frequency and severity have also increased in the past five decades in natural, regulated and highly regulated basins. Recent positive trend in the atmospheric water demand has had a direct influence on the temporal evolution of streamflows, clearly identified during the warm season, in which higher evapotranspiration rates are recorded. This pattern of increase in evaporative demand and greater drought severity is probably applicable to other semiarid regions of the world, including other Mediterranean areas, the Sahel, southern Australia and South Africa, and can be expected to increasingly compromise water supplies and cause political, social and economic tensions among regions in the near future.
Copernicus provides a unified system through which vast amounts of data are fed into a range of information services designed to benefit the environment, the way we live, humanitarian needs and support effective policy-making for a more sustainable future.
Here are a few examples of the possible applications in different thematic areas. Additional ones will be regularly published, so check back for more to come!
Why would anyone want different versions of data? Don’t we all want data we can trust, that doesn’t vary from copy to copy? The answer is yes, sometimes. Boundless CTO Juan Marin explains how GeoGig can manage versioned geodata.
In their wonderful book about the science of successful learning, Make It Stick, Peter Brown, Henry Roediger, and Mark McDaniel spell out some truths that I believe are instructive as to how we should approach teaching with GIS.
First, the authors claim that ”learning is deeper and more durable when it’s effortful. Learning that’s easy is like writing in sand, here today and gone tomorrow.” Despite the fact that teaching and learning with GIS is far easier than it was a decade ago, I think we as educators do a disservice to our colleagues in education or to students when we say, “it’s easy.” First of all, teaching and learning are difficult tasks–neither is for the fainthearted. Second, think of everything that goes into teaching with GIS–a balance between content knowledge, skills, and the geographic perspective. Yes, it may be easier technically to bring in a CSV file into ArcGIS Online than it was to bring in a spreadsheet into ArcInfo back in the 1990s, but even this skill relies on some key foundations. A few of these are: What is a database and how can I create one? How can locations be mapped? How can I work with latitude and longitude pairs, or street addresses? What are the pros and cons of choosing a certain map projection over another?
South Australian motorists are turning to a cutting-edge mapping website that’s helping them avoid traffic congestion and plan quicker, more efficient road trips. The interactive Traffic SA mobile site – which highlights traffic accidents, road closures and major events across metro and country areas – is attracting up to 1,500 unique daily visitors.

Esri is compiling a human geography database of demographics and statistics about all countries in the world and mapping this data using an innovative methodology.
Sociodemographic data is a valuable asset for businesses, governments, and society. Describing and understanding the human geography of the world requires tools to assimilate data in a statistically valid way that will allow for meaningful decision making.
Traditionally, people are counted in a census. But a census is time-consuming, costly, and does not collect the types of statistics at the level required to address today’s complex societal issues.
New real-time technology is expected to shave millions of dollars from the operational costs of Australian businesses, according to an industry expert. Esri Australia Business Solutions Manager Doug van Gelder has advised leading asset managers how smart mapping technology is set to revolutionise the way organisations manage their infrastructure at the Asset Management and Maintenance …
Topcon Positioning Group and MAVinci have announced that the latest version of the Sirius Pro surveying UAS (Unmanned Aerial System) is designed to be compatible with existing RTK (Real Time Kinematic) base stations or NTRIP (network transport of RTCM data over IP). The system will be available at the Intergeo trade show for geodesy in October and thereon.
The Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS) takes advantage of the 30 year Landsat archive to inventory recent disturbances and forest-cover change. Using mid-summer, cloud free Landsat data from the Global Land Survey (GLS) project, LEDAPS first corrects the images to remove atmospheric effects from surface reflectance (source code for LEDAPS) before applying [...]
