2010 USDA Forest Service, Rocky Mountain Region Aerial Detection Survey Data. This data depicts the occurrence and location of forest insect, disease, and other biotic and abiotic causes of tree mortality and tree damage. Aerial survey data is collected by observing areas of tree damage or tree mortality from an aircraft and manually recording the information onto a map. Due to the nature of aerial surveys, this data will only provide rough estimates of location, intensity and the resulting trend information for agents detectable from the air. Many of the most destructive diseases are not represented in the data because these agents are not detectable from aerial surveys. The data presented should only be used as...

NAIP horizontal accuracy specifications - From 2003 to 2004 the specifications were as follows: 1-meter Ground Sample Distance (GSD) imagery was to match within 3-meters, and 2-meter GSD to match within 20 meters of reference imagery. For 2005 the 1-meter GSD specification was changed to 5 meters matching to reference imagery. In 2006, all states used the same specifications as 2005 except for Utah, which required a match of +/- 6 meters to true ground. In 2007, all specifications were the same as 2006, except for Arizona, which used true ground specifications. In 2008 approximately half of the states acquired used true ground specifications and the other half used reference imagery. The 2008 states that used absolute...

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system were developed to define an updated hydrogeologic framework as part of the U.S. Geological Survey Groundwater Resources Program. This feature class contains the first magnitude springs of the first magnitude springsheds.
