The United States Geological Survey has created a new map that highlights where natural and man-made earthquakes could cause damage around the country.
Launched in 2013 by NASA, Landsat 8 is the latest satellite in the series. The mission of the orbiting satellite is to map and track changes on Earth. Under the control of the USGS, the satellite continues the more than forty year earth observation legacy of the Landsat program. Available in […]
The U.S. Geological Survey’s Center for Integrated Data Analytics (CIDA) has created an open source visual description of California’s ongoing drought using free and publicly accessible GIS data sources. Noting that many state, federal, and tribal agencies make routine observations of the water cycle, the USGS developed this graphic to visualize […]
On July 23, 1972, the first Landsat spacecraft was launched. At the time it was known as the Earth Resources Technology Satellite and it was the first satellite launched to study the earth’s landmasses. In 1975, the name was changed to Landsat. Since then, this program has been continuously monitoring changes […]
The USGS recently published a report looking at case studies of Landsat Imagery use in water resource management within public and private entities. The Landsat satellite imagery program has been collecting data since 1972 and is available for free to the public. Entitled, “Landsat and Water—Case Studies of the Uses […]
The U.S. Geological Survey and Esri are working together to make over 178,000 maps of the United States available to the public via an online map explorer. The USGS Historical Topographic Map Explorer lets users browse the extensive collection of scanned maps. Since its official launch in September of 2011, the USGS has led an effort […]
Between the 1880s and the 1950s, the USGS produces engravings used to reproduce topographic and geologic maps within the agency. Many of the excess engravings are being readied for sale or donation by the USGS. The metal engravings are mostly copper alloy with a few made of zinc. Most of […]
The U.S. Government shutdown has led to the unfortunate darkening of many of its sites. Many sites that offer sources of GIS data have been shuttered. Many of these government sites like the USGS, Census Bureau, NASA, NOAA, USDA, and Data.gov are invaluable sources of geospatial information. Only sites like weather.gov from […]
Visitors to the Menlo Park USGS library will notice a painting entitled, “Cartographers in the Field”. The painting depicts two cartographers out in the field. The picture was painted by Hal Shelton in 1940 who was a fieldman at the time with the USGS. A side plaque notes, “The painting […]
The U.S. Geological Survey is putting out a call for citizen scientists (that means you) to help them track and gather geographic information on what is happening all around the globe. Here are the some of the most well-known USGS crowdsourcing projects.
There are several map services that USGS supports. These allow you to view nationwide data from The National Map in your GIS software. To use these in ArcGIS – select Add Data button then choose GIS Server from the list, then “add ArcGIS Server” To add the tiled map cache (these are […]
The series of Landsat satellites has been collecting global imagery continuously since 1972. A total of eight satellites and millions of pictures (and trillions of pixels) has resulted in a hugh amount of imagery which, when compiled, visualizes the massive amount of global change over the past thirty+ years. Landsat […]
