U.S. - Mexico Border Environmental Health Initiative The map is a seamless, binational 1:5,000,000-scale geologic map of the entire U.S.-Mexico border region, and is a clipped-out portion of The Geologic Map of North America, published by the Geological Society of America (GSA)(Reed and others, 2005-see citation below). The map is a geo-referenced image that can be loaded on the U.S.-Mexico Border Environmental Health ArcIMS website as a backdrop for analytical comparison with other geographic, biologic, or hydrologic GIS datasets. In addition to the geology, the map includes selected major cities, rivers, and state and country boundaries.

Lesson: Identifying Geological Structures in DEMs: Background Information Background information on Mount Hood Snow-clad Mount Hood (3,426 meters - 11,239 feet) dominates the Cascade skyline from the Portland metropolitan area to the wheat fields of Wasco and Sherman Counties. The mountain contributes valuable water, scenic, and recreational resources that help sustain the agricultural and tourist segments of the economies of surrounding cities and counties. Mount Hood is also one of the major volcanoes of the Cascade Range, having erupted repeatedly for hundreds of thousands of years, most recently during two episodes in the past 1,500 years. The last episode ended shortly before the arrival of Lewis and Clark in 1805. Regional Geology Mt. Figure 1: Structures in the Mount Hood Region.

New York City < back up to USA New York State GIS Clearinghouse some layers are free available for the whole state: DRG, NLCD there are beautiful color Orthoimagery for most the western and central counties (but not NYC), and false-color (CIR) image for nearly the whole state, excepting parts of NYC others layers are expensive, but free to member of the NY State GIS Data Sharing Cooperative 1:100k Hydro, public roads in ArcInfo format from May 2002 to November 2003, a lot of the data was put offline due to paranoia, including NYC DRGs, but it appears that it's currently (nearly) all back up City of Ithaca Attractive for visualization because of amazingly complete and public GIS data for the whole city: includes parcel boundaries, building footprints, road widths and curbs, sidewalks, driveways, even every individual planted tree For years it was at , but as of 2011 that is gone and the data is probably somewhere inside CUGIR: Cornell University Geospatial Data Information Repository (CUGIR) State Plane Base Map

Mount Hood: Interactive timeline traces peak's history Mount Hood, the highest point in Oregon, is a state icon. Located about 50 miles east of Portland the mountain is one of the most climbed glaciated peaks in North America. It is part of the Cascade Mountain Range that also includes Mount Adams, Mount St. Helens and Mount Rainier. Mount Hood is a popular ski and snowboarding destination with multiple resorts. Olympic snowboarders from around the world train here during the summer months. The most well known lodging destination on the mountain is Timberline Lodge. Mount Hood has 12 named glaciers and snowfields, the largest glaciers, Coe and Eliot, are located on the north and northeast side of the mountain. The 11,240 foot tall mountain is the heart of the Mount Hood National Forest, a million-acre forest that more than 2.6 million people visit annually, according to the U.S. There are 314,078 acres of designated wilderness in the forest.

SGIS - Orthoimagery - Web Map Service GIS web services allow users to connect to data sources through the internet rather than downloading and storing copies of the data on their own systems. The NYS ITS GIS Program Office is pleased to provide access to statewide orthoimagery coverage through web services. Users are encouraged to use the services to display orthoimagery in their desktop GIS and web applications. All available NY Statewide Digital Orthoimagery Program (NYSDOP) data (2000-2012) and the USGS National Aerial Photography Program (1994-1999) data are available through web services hosted by the NYS ITS GIS Program Office. Information on connecting is available at gis.ny.gov/gateway/mg/webserv/webserv.html. In partnership with USGS, NYS ITS GIS Program Office also has made many years of the NYSDOP imagery available through services hosted by USGS.

Using GIS to Digitize Historic Geologic Maps | Annotated bibliography summarizing resources related to georeferencing and digitizing historic geologic maps using the GIS. Completed as course requirement for GIS 565, Geographic Information Systems & Scienc Data.gov The National Map: Historical Topographic Map Collection Historical Topographic Maps - Preserving the Past In 2009, USGS began the release of a new generation of topographic maps (US Topo) in electronic form, and in 2011, complemented them with the release of high-resolution scans of more than 178,000 historical topographic maps of the United States. The topographic map remains an indispensable tool for everyday use in government, science, industry, land management planning, and recreation. Historic maps are snapshots of the nation's physical and cultural features at a particular time. The goal of The National Map’s Historical Topographic Map Collection (HTMC), which started in 2011, is to provide a digital repository of USGS 1:250,000 scale and larger maps printed between 1884, the inception of the topographic mapping program, and 2006. GeoPDF® versions of HTMC maps can be downloaded free of charge from these applications: For tutorial information on download and product use, see the US Topo Users Guide.
