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.

Landslide Mapping Needed in North Carolina
November 26, 2013 | WSPA.com

Hundreds of landslides occur every year in North Carolina but lawmakers have almost eliminated a program that can help developers avoid building homes, commercial and public buildings on ancient landslides and slide-prone areas. It can also help the state highway department and utility companies avoid building roads and pipelines across ancient landslides and slide-prone areas. This one-time job was costing about $350,000 per year and would only require mapping the western part of the state where most landslides occur.

In a 24-year period landslides in the state killed 7 people and destroyed 85 homes. Not available is how much is spent on repairs to roads and utilities. The annual cost of these is undoubtedly many times the cost of the landslide mapping program – which is temporary.

The economics of this project suggests that millions per year should be spent to get it done as quickly as possible – but lawmakers decided to cut it.
