10_9 Earth Imaging Broadcast (Land-Cover Change, Seafloor Maps and More)

Hello, and welcome to this Earth-Imaging-themed GeoSpatial Stream. I’m your host, Todd Danielson, and today’s Lead Sponsor is Trimble Geospatial Division.

Today’s Top Story is Land-Cover Change. Researchers at the USGS Earth Resources Observation and Science Center have developed the FOREcasting SCEnarios of land-cover-change model based on consistent and systematic historical data derived from Landsat satellite imagery of rates and spatial patterns of land-cover change over many years.

As part of USGS research to assess potential greenhouse gas fluxes and carbon storage in vegetated landscapes, this model has been used to produce projected, annual land-cover maps from 1992 through 2100 for four future scenarios for the conterminous United States. The land-cover maps provide 250-meter-resolution information for 17 different land-use and land-cover classes.

That was today’s Top Story. I’ll be back with more news after this brief message.

Scientists at Scripps Institution of Oceanography at UC San Diego and colleagues created a new map of the world’s seafloor, creating a vivid picture of the structures that make up the deepest, least-explored parts of the ocean. Here’s a clip from an accompanying video that I’ll also post on GeoSpatial Stream in its entirety:

In this episode, I’m showcasing several cool video clips I’ve recently come across. This 3-D video from NASA describes its new Global Precipitation Measurement satellite:

In industry headlines, Rapidlasso introduced LASzip “compatibility mode” for LAS 1.4, which deploys a point re-coding strategy so legacy LiDAR software can support new point types.

Sewall hired Connie Li Krampf as a certified photogrammetrist/analyst to complement and strengthen Sewall’s imaging and mapping capabilities.

And Optech released its Optech LMS 3.0 Lidar Mapping Suite for airborne and mobile workflows, simplifying the pre-processing and calibration of multi-sensor imaging systems for maximum efficiency and accuracy.

For today’s Final Thought, here’s one more video clip from an Intel contest on wearable technology. It’s a little small to image the Earth, but it’s only a matter of time:
