Integration of Under-utilized USGS Data Sets

This research partition looks at integrating various data sets with The National Map data layers in order to promote scientific endeavors, public safety, economic assets or quality of life. Recent efforts have included:

Historic Geologic Maps

In many areas the next generation geo-referenced, digital geologic maps are as yet unavailable.  Therefore, in order to integrate geologic data some other means of data acquisition is necessary.  A method to conflate historic geologic maps for an area and integrate the digital results with The National Map data was devised for various geologic map fragments from in and around Ste. Genevieve County, Missouri.

The figure on the right shows the map fragments used in conflating the digital map.

Five geologic maps of various publication dates are conflated with the large scale geologic map of Ste. Genevieve County of Weller and Clarke, 1922.  These are then integrated with data from The National Map.

Figure on the left shows the conflated digital geologic map of the area around Ste. Genevieve County, Missouri. Data is also integrated with The National Map layers. (Shoberg, 2016)

Soil Data

Soils are an essential resource for the United States. Several different digital soil data repositories exist, but the Soil Survey Geographic database (SSURGO) has a scale and resolution most compatible with geologic and topographic map data. A method was devised to integrate the SSURGO data set with geologic map and The National Map hydrographic layer “on the fly”. The results are shown for Ste. Genevieve County, Missouri on the right.

Bison Data

Biodiversity Information Serving our Nation (BISON) data from the USGS is integrated with digital geologic map data and The National Map layers to provide geographic context for specimen location. The specimens chosen for the initial study included fossil and fish, but this has since been extended to the other specimens in the BISON dataset. The area of study was Ste. Genevieve County, Missouri.
