Missouri Geosciences Technical Resource Assessment Tool
April 3, 2014 | Missouri Geological Survey

The Missouri Geological Survey has recently launched a new online tool called the Missouri Geosciences Technical Resource Assessment Tool. GeoSTRAT is a web application that makes geologic and hydrologic data readily available for public use. GeoSTRAT enables users to easily visualize and explore geospatial data using an interactive map developed on an Esri and Google platform to allow 3D viewing of the land surface. Data can be downloaded in formats compatible with a variety of free and commercial mapping software and includes layers such as geology, bedrock elevation, water wells, sinkholes, historic mine locations, caves, springs, dye traces, well logs, aquifers, losing streams and a host of other coverages and associated metadata. GeoSTRAT can be used in the office or in the field for site assessments in areas such as geologic hazards, geotechnical consulting and engineering, emergency response, local and regional planning, water availability and a multitude of other purposes.

USGS Topo Maps on Your Phone
May 6, 2013 | USGS

“Android and iPhone users can now use their mobile devices as digital topo maps, leveraging USGS maps together with the power of GPS to zoom in on their precise location while hiking, biking, running, or any other activity that benefits from precision navigation.” Quoted from the USGS announcement.

USGS Crowd-Sourcing Test
April 5, 2013 | USGS

“Over a trial period of ten months, 143 volunteers collected, improved, or deleted data on more than 6,400 structures in Colorado. The volunteers’ actions were accurate and exceeded USGS quality standards. In the Colorado pilot project the volunteer-collected data showed an improvement of approximately 25 percent in both location and attribute accuracy for existing data points. Completeness, or the extent to which all appropriate features were identified and recorded, was nearly perfect.” Quoted from the USGS summary.
