Both large full size satellites as well as small satellites are now being used for various purposes around the globe. In addition, constellations of satellites are being developed for specific purposes, such as internet satellites. We also include here maritime surveillance that relies on Satellite Automatic Identification System (AIS) payload.

This questionnaire is aimed toward those who do research and development on traditional artificial satellites and “smallsats,” as well as those customers of satellites, and companies providing third party solutions for them. Since companies of larger satellites produce small satellites as well, larger satellites, their features and their pros and cons are included in this questionnaire.
Front and center in the news right now is Hurricane Harvey and resulting devastation, which will most likely remain in the news for awhile.
Climate Migrants is an Esri Story Map that tells the story of people misplaced geographically by climate change and in some cases, other change factors. Allan Carroll of Esri and his team wanted to create a climate change map that was oriented toward people.
The primary goal of the team is to produce apps that enable other people to tell stories. An analysis report by the Wilson Center in Washington, D.C. was an influence in the development of the Story Map, which charts what factors contribute to people becoming “climate migrants.” In some cases, such as Syria and Darfur, droughts have precipitated migrations and led to violence and war.
“Some like these, are caused by both climate change and political indicators, sometimes by shortsighted government policies, but climate is a factor in all of them,” said Carroll.
Reviewing 2016 through the lens of GIS, there has definitely been a lot of growth in certain areas. While we have had the cloud on our list of important technologies for a few years now, it is gaining more traction as more organizations take advantage of its fluidity, ability to house big data and allow teams to work together, and also roll out product releases with more ease.
About two weeks ago, Esri launched a collection of web maps that display NOAA forecast streamflow data for the continental U.S. NOAA’s recently released National Water Model. Data from the Model combined with the National Hydrography Dataset and fed by NOAA’s National Weather Service data, forecasts the flow of water along the 2.7 million stream segments in the continental U.S. in ArcGIS Online.
