GameSim announces CRADA with the NGA

Thursday, December 4th, 2014

The notion of gaming and geospatial coming together has been explored for some time. Gaming simulation and GIS software provider GameSim Inc. announced a Cooperative Research and Development Agreement (CRADA) with the National Geospatial-Intelligence Agency. (NGA). This agreement will give credence to GameSim’s 3D environment with standards and data created and validated by the NGA.

In 2013, GameSim, ranked by Inc. Magazine as one of the 500 fastest growing companies in the U.S., introduced an innovative software product, Conform (gamesim.com/conform), which generates a 3D representation of an environment from GIS data (vectors, elevation, and imagery) in near real-time. The integrated scene can be viewed in both 2D and 3D, or exported, into other run-time formats.

GameSim was interested in furthering their process of fusing together a single 3D environment by supporting additional data products (e.g., LiDAR, OTW video, and thermal video), to create a more accurate and rich 3D environment, while still maintaining near real-time performance. GameSim had previous experience working with these formats. The agreement with NGA through CRADA will provide the company with proper standards and data validated by NGA. In addition, GameSim and NGA will research the creation of a low bandwidth, browser-based visualization of that fused environment, according to GameSim company materials.

“We are creating a product that can fuse a variety of formats that adheres to established standards,” said Andrew Tosh, GameSim founder and president. “By collaborating with NGA it helps assure that GameSim produces a product that can meet the demands of the intelligence community, in terms of accessing their content and producing valuable visualizations.”

 

Special GISCafe Coverage: 3D Cities: Envisioning Communities of the Future

Friday, November 21st, 2014

Cities worldwide are charged with the same challenge: that of creating or retrofitting sustainable, intelligent infrastructure. Cities need the best in design, geospatial, visualization and analytical tools to realize a viable and intelligent city design. 3D City design is architectural design times thousands, plus it must have the ability to be interwoven with other surrounding infrastructure and foster an urban conversation.

Special Coverage: UAS: Disruption in the Skies

Thursday, October 23rd, 2014

Unmanned Aerial Systems is one of the disruptive technologies of this century. Whomever would have thought that small flying planes, that look very much like the hobbyist planes that people fly remotely, would someday take the role of carrier pigeons in delivering packages and also providing aerial surveillance, both on a government and citizen level.

Special Coverage: Online GIS Courses Change the Face of Geospatial Education

Thursday, August 28th, 2014

The face of GIS and Geospatial education has changed dramatically over the past few years, with online courses being offered in numerous subjects, ranging from GIS fundamentals to Spatial Analytics and Geodesign. What is more phenomenal is that these courses reach out to all corners of the earth, making a GIS/geospatial education a possibility for almost everyone on the planet.

NASA needs help from citizen science

Tuesday, August 26th, 2014

A recent CNN report announced thatNASA is asking for the help of citizens in viewing hundreds of thousands of images taken from space over the years, from the 1960s Mercury missions to the present images snapped from the International Space Station.

North Korea is barely lit when juxtaposed with neighboring South Korea and China.

Via The Gateway to Astronaut Photography of Earth, NASA is making these images available for citizens to examine.

NASA says the hope is that the images “could help save energy, contribute to better human health and safety and improve our understanding of atmospheric chemistry. But scientists need your help to make that happen.”

The catalog contains more than 1.8 million photos, about 1.3 million of them from the space station and roughly 30% of them taken at night.

The CNN report said that before 2003, night images from the space station could be blurry, even with high-speed film and manual tracking, because the station moves at about 17,500 mph. In that same year, astronaut Don Pettit used a drill and assorted parts he found on the station to cobble together a “barn-door tracker,” a lower-tech predecessor to the European Space Agency’s NightPod, which was installed at the space station nine years later.

According to the report, NightPod’s motorized tripod compensates for the space station’s speed, providing what NASA scientist William Stefanov says are the highest-resolution night images from orbit. Satellites collect data more regularly, but the photos tend to be lower resolution. “Now the pictures are clear, but their location may not be, which limits their usefulness,” the NASA news release says.

Citizen science has a better handle on location than the night images from the space station and satellite imagery. The Complutense University of Madrid is spearheading efforts to get citizen input and organize the photos.  They have broken down the  the images into three components requiring different levels of participation:

1. Dark skies. This is the easiest project, as it requires no scientific expertise. “Anyone can help” by sorting the images into the categories: cities, stars or other objects, said Alejandro Sanchez, doctoral student at Complutense.

“Without the help of citizens, it is almost impossible to use these images scientifically. Algorithms cannot distinguish between stars, cities and other objects, such as the moon. Humans are much more efficient for complex image analysis,” he said.
