3D Geoinformation from Satellite Sensors
The notion of “3D GIS” has been gaining momentum in the geospatial industry for a few years now. Realistic 3D vector data, Building Information Modeling (BIM), 3D terrain and imagery are all important components of building a GIS infrastructure that goes beyond two dimensions. The convergence of GIS, photogrammetry and remote sensing data, tools and methods has now matured to the point of making integrated 3D GIS applications a reality.
ERDAS Engine - Increasing Throughput in a Cost-effective Fashion
As geospatial analysts process the extremely large imagery datasets that are typical in this industry, they are faced with a choice: save money by slowly generating data products using existing resources, or purchase additional software licenses to increase the number of processes that can be executed simultaneously. ERDAS Engine enables organizations to radically boost processing efficiency for less money.
Rein in 3D Point Clouds with the LAS Format
The advent of LiDAR sensors has been valuable for the geospatial industry, but there have been some challenges as the community attempts to fully leverage the technology.
The New Paradigm: Leveraging the "Information Cloud" with the Dynamic GIS
The Dynamic GIS, which completely connects sensors to software and software
to solutions through specific vertical market services, ultimately provides a means
to protect lives, infrastructure, and society. An integrated geospatial system, the
Dynamic GIS is able to translate change, on the fly, into actionable information. The
earth is constantly changing, and snapshots of geography can be captured from
airborne, orbital, terrestrial, or hand sensors and saved as a permanent record of
events happening on the earth’s surface.
Volumetric Measure Using Geospatial Technology
Using high-resolution terrain information generated from stereo imagery, you can obtain volumetric measurements for monitoring and surface analysis. In this whitepaper, we detail workflows that could be used for such a task. We will prepare the project and stereo imagery, create a digital surface model (DSM), and take volumetric measurements. For our demonstration, the goal is to collect volumetric measurements that show how much earth has been removed from a quarry or mine. However, this process could also be used for a variety of applications.
