Drones and robots complement traditional platforms, delivering insights in unique use cases. Guest column by Mike Fuller Geographic surveys have changed in the last 150 years. What started with early film cameras strapped to hot air balloons, kites and homing pigeons has advanced — both in terms of sensors and the platforms on which they’re deployed. These innovations — which include... read more

Guest column by Sanchit Agarwal Vice President, Field Operations, Nearmap With high-resolution imagery comes the ability to model reality, creating real-life visualizations for engineers, planners, construction teams and many others. A quantum leap in computing capacity has allowed us to model and analyze the real world — all from our desktop and mobile devices. In days past, maps were purely for... read more

6 story maps show how data can illustrate the world

Story maps combine geographic data with  multimedia to tell a story and present information in a useful, interesting way.  While many story maps are designed for general, non-technical audiences, some story maps can also serve highly specialized audiences. They use the tools of GIS, and often present the results of spatial analysis, but don’t require their users to have any special... read more

Making cities cleaner, providing better services and housing, and decreasing pollution are all achievements of nine cities recognized for using data to improve citizens’ lives. In January, Bloomberg Philanthropies announced that nine cities have achieved What Works Cities certification, a first-of-its-kind national standard of excellence in city governance. What Works Cities certification rates how well cities are managed by measuring the extent to which city leaders... read more

Descartes-search

Where are all the windmills on Earth? Or oil derricks? How about baseball stadiums? You could scan through the millions of satellite images snapped by hundreds of satellites now circling the planet. Or you could try Descartes Labs’ demo search engine. Satellites are snapping images of the Earth every day. Alongside Planet Inc. and DigitalGlobe satellites, constellations are planned from companies such as Urthecast... read more

The media is buzzing about the Great American Solar Eclipse that takes place Monday, Aug. 21.  It’s a historic event that last occurred 99 years ago. To be clear, 99 years ago is when the last total solar eclipse traversed the entire continental United States (lower 48 states). To put that timeline in perspective, only one of the following inventions... read more

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... read more

By Will Fellers Remote sensing technology has come a long way and is delivering serious benefits across a wide range of industries. Since the early 1970s, when the first LANDSAT satellites were launched, there has been rapid technological innovation in platform architecture and sensor technology used to collect both active and passive spectral information. These advancements have dramatically changed the... read more

Esri Collector

I’ve attended a couple of Esri events these past couple of months. They are on the move. For a big software company (est. $1 billion in annual revenues), they are reasonably nimble. Of course, if you’ve worked with Esri software, no doubt you’ve been frustrated at times, but considering the size of the organization and the dynamic nature of GIS... read more
