New Earthquake Maps from the USGS Also Factor Human Activity Induced Causes

April 1, 2016By Elizabeth BornemanGIS Learning

The United States Geological Survey has created a new map that highlights where natural and man-made earthquakes could cause damage around the country.

The 2015 earthquakes caused great damage in Bhakatpur, Nepal. These photos are overlaid on a damage proxy map derived from COSMO-SkyMed satellite data. Colors show increasingly significant change in terrain/building properties (including surface roughness and soil moisture). Red is most severe.

Virginia Quake Maps

August 25, 2011By Caitlin DempseyMaps and Cartography

A magnitude 5.8 earthquake hit Virginia on August 23rd and was felt across a large portion of the eastern side of the United States. The epicenter was located in central Virginia. The last time an earthquake that strong hit the Virginia areas was one reported in May of 1897, a magnitude 5.9 […]

Using Satellite Imagery to Track Volcanic Ash Clouds

Researchers have developed an algorithm that can distinguish between volcanic and non-volcanic clouds using high-resolution satellite imagery.

Using Machine Learning and Satellite Imagery for Street Address Generation

Researchers from Facebook and MIT Labs have proposed a new methodology that uses machine learning and satellite imagery to generate street addresses in areas of the world where individual buildings don’t have a unique address.

Elements of a Map

Maps are the primary tools by which spatial relationships are visualized. Maps therefore become important documents. There are several key elements that should be included each time a map is created in order to aid the viewer in understanding the communications of that map and to document the source of […]
