U.S. Geological Survey Upper Midwest Environmental Science Center 20070406 raster digital data http://www1.usgs.gov/vip/indu/induortho.zip doi:10.5066/F7BG2KZW Color infrared (CIR) aerial photographs were acquired as baseline imagery data to produce vegetation spatial database coverages of Indiana Dunes National Lakeshore (INDU) and environs. The aerial photos were collected on October 21, 2004 and October 24, 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 East Unit, West Unit with Calumet Prairie, Pinhook Bog, Heron Rookery, Hobart Prairie Grove, and Hoosier Prairie units and their environs. The photo mosaics are raster datasets compressed with MrSID (LizardTech), projected in Universal Transverse Mercator (UTM), Zone 16, 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 Indiana Dunes 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 Williams Aerial & Mapping, Inc. in South Bend, Indiana. During the registration process the data were resampled by UMESC using the software program IrfanView, to a resolution of 635 dots per inch, to produce a final image containing 0.5-meter square pixels. 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/plugins.php. The initial product delivery for the Indiana Dunes National Lakeshore Vegetation Mapping Project was in October 2008. An update to select products was completed in September 2009. Since the initial delivery of products, the program name has undergone a name change. For purposes of this metadata, most references to the "USGS-NPS Vegetation Mapping Program" are now the "NPS Vegetation Inventory Program." Occasionally, references to point of contacts are now the "USGS Vegetation Characterization Program." 20041021 20041024 ground condition Complete None planned Indiana Dunes National Lakeshore and environs -87.484003 -86.823354 41.726286 41.497692 None Aerial Photographs Aerial Photography Color Infrared Photo Mosaic Orthophoto U.S. Geological Survey National Park Service USGS-NPS Vegetation Mapping Program Geographic Names Indiana Dunes National Lakeshore INDU East Unit West Unit Calumet Prairie Pinhook Bog Heron Rookery Hobart Prairie Hoosier Prairie Lake County La Porte County Porter County Indiana USA None None Software capable of viewing MrSid format image files (version 1.4) is required to access these data.

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 (INDU park boundary with 400-meter buffer). The horizontal positional accuracy was tested by visual comparisons between the orthorectified INDU 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.

U.S. Geological Survey Eros Data Center Unknown raster digital data Sioux Falls, SD U.S. Geological Survey 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 24000 Digital database file Unknown Unknown 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 0.5x0.5-meter pixels. 2004 CIR Aerial Photographs True-Color Orthophotos 1/3 NED Data 20061001 Each image was trimmed to remove camera fiducials (i.e., registration marks) from the images. Unknown The software program Image Analysis 1.1 was used to mosaic the orthorectified aerial photos for three of the units (East Unit, West Unit with Calumet Prairie, and Hobart Prairie Grove), and the software program Orthomapper version 3.23 was used to mosaic the remaining three units (Pinhook Bog, Heron Rookery, and Hoosier Prairie). These images were stored in Tagged Image File Format (TIFF). 20070301 The software program MrSid Geospatial Encoder version 1.4 was used to compress the individual mosaics using a 20:1 compression ratio. The result was six orthorectified MrSid (.sid) format images. 20070301 USGS - Upper Midwest Environmental Sciences Center Resource Mapping and Spatial Analysis Team mailing and physical address
