U.S. Geological Survey, Upper Midwest Environmental Sciences Center, 2630 Fanta Reed Road, La Crosse, Wisconsin 54603; 608-783-6451 Unknown raster digital data USGS-NPS Vegetation Mapping Program Apostle Islands Vegetation Mapping Project La Crosse, WI UMESC http://www1.usgs.gov/vip/apis/apisortho.zip doi:10.5066/F7736NTQ Color infrared (CIR) aerial photographs were acquired as baseline imagery data to produce vegetation spatial database coverages of Apostle Islands National Lakeshore (APIS) and environs. The aerial photos were collected on October 9, 2004 at a scale of 1:12,000 to capture peak fall leaf phenology. The U.S. Geological Survey (USGS) Upper Midwest Environmental Sciences Center (UMESC) of La Crosse, Wisconsin has produced spatially referenced aerial photo mosaic images of the aerial photographs for the individual island complexes that make up the Apostle Islands. The photo mosaics are raster datasets compressed with MrSID (LizardTech), projected in Universal Transverse Mercator (UTM), Zone 15, using the North American Datum of 1983 (NAD83). The 2004 color-infrared aerial photo mosaics were developed for use as a general reference image and to assist in the identification of vegetation. The aerial photo mosaics were produced as by-products from the Apostle Islands National Lakeshore Vegetation Mapping Project, USGS-NPS Vegetation Mapping Program. The USGS-NPS Vegetation Mapping Program is a cooperative effort by the U.S. Geological Survey and the National Park Service to classify, describe, and map vegetation communities in more than 270 national park units across the United States. This landmark program is both the first to provide national-scale descriptions of vegetation for a federal agency and the first to create national vegetation standards for its data products. Its goal is to meet specific information needs identified by the National Park Service. The software program MrSid Geospatial Encoder version 1.4 was used to compress the photo mosaic, at a rate of 20:1. The 9x9-inch aerial photo transparencies were collected at a scale of 1:12,000 and scanned at a resolution of 1270 dots per inch by Ayers Associates in Eau Claire, WI. A software program capable of viewing these data is required to access the compressed mosaic. Freeware viewers are available from the LizardTech software company, at http://www.lizardtech.com/. Some of the newer viewers have difficulties reading this particular image. Users need to make sure they download a viewer capable of accessing images created using version 1.4 MrSid Geospatial Encoder software. Also, web browser plugins that allow anyone to view, measure, or export any MrSID images using Internet Explorer or Firefox can be found at http://www.lizardtech.com/downloads/index.php. 20041009 ground condition Complete None planned Apostle Islands National Lakeshore and environs -91.080338 -90.372212 47.105877 46.662120 None Aerial Photograph Aerial Photography Color Infrared Photo Mosaics Color Infrared Apostle Islands National Park Service U.S. Geological Survey NPS USGS USGS-NPS Vegetation Mapping Program Orthophoto None Apostle Islands Wisconsin USA Bayfield County Ashland County If the user wishes to view the data as georeferenced data, a computer software program capable of reading and displaying data stored as a georeferenced image is required.

None Unclassified None Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.2.2.1350 As the orthorectified images were created, each processing step included procedures used to check the content and spatial accuracy. If at any time the product did not meet the standards set for a processing procedure, the procedure was repeated. Every aerial photo was orthorectified within the project boundary (APIS park boundary with 400-meter buffer). The horizontal positional accuracy was tested by visual comparisons between the orthorectified APIS color-infrared aerial photographs and existing high-resolution true-color orthophotos for the same area. The referenced orthophotos had a horizontal root mean square error (RMSE) of no greater than 2.0 meters.

Orthorectifying was completed using Orthomapper. U.S. Geological Survey Eros Data Center Unknown 1 data The U.S. Geological Survey has developed a National Elevation Dataset (NED). The NED is a seamless mosaic of best-available elevation data. The 7.5-minute elevation data for the conterminous United States are the primary initial source data. In addition to the availability of complete 7.5-minute data, efficient processing methods were developed to filter production artifacts in the existing data, convert to the NAD83 datum, edge-match, and fill slivers of missing data at quadrangle seams. One of the effects of the NED processing steps is a much-improved base of elevation data for calculating slope and hydrologic derivatives. The specifications for the NED 1 arc second and 1/3 arc second data are: Geographic coordinate system Horizontal datum of NAD83, except for AK which is NAD27 Vertical datum of NAVD88, except for AK which is NAVD29 Z units of meters http://gisdata.usgs.gov/website/seamless/viewer.htm unknown Digital database file unknown ground condition 1/3 NED Data NED was used as the elevation data for orthorectifying the 2004 CIR Aerial Photographs. Orthorectifying was completed using Orthomapper. The software program Orthomapper version 3.23 was used to orthorectify the individual aerial photographs. During this process, existing orthophotos for the region were used to obtain coordinates for various points on the photos, and existing elevation data were used to provide elevation information. The orthorectification process uses these data inputs to (a) determine where on earth the image was collected, and (b) remove distortions that may exist within the image, or were caused by changes in elevation. The output images contained 0.25x0.25-meter pixels. 2004 CIR Aerial Photographs True-Color Orthophotos 1/3 NED Data Unknown Each image was trimmed to remove camera fiducials (i.e., registration marks) from the images Unknown The software program MrSID GeoSpatial Encoder 1.4 was used to mosaic the orthorectified aerial photos for all 19 islands.
