An orthoimage (DOQ) is remotely sensed image data in which displacement of features in the image caused by terrain relief and sensor orientation have been mathematically removed. Orthoimagery combines the image characteristics of a photograph with the geometric qualities of a map. For this dataset, the natural color orthoimages were produced at 0.3-meter pixel resolution (approximately 1-foot). The design accuracy is estimated not to exceed 6 meter horizontal RMSE for locations within the United States. Each orthoimage provides imagery for a 1500-meter by 1500-meter block on the ground. The projected coordinate system is UTM with a NAD83 datum, spheroid GRS80. There is no image overlap between adjacent files. The naming convention is based on the U.S. National Grid (USNG), taking the coordinates of the SW corner of the orthoimage. --------------------------- Note: This metadata record was created by the Minnesota Geospatial Information Office (MnGeo) based on the metadata provided by 3001, Inc. for individual Zone 15 tiles. It describes the layers that MnGeo created for its WMS service from the tiled dataset. ---------------------------

This dataset contains 265 digital, black and white orthophoto quarter-quadrangles (DOQs), 3.75' x 3.75', covering the 7 county Twin Cities (Minneapolis and St. Paul) Metropolitan Area in Minnesota. Each CD-ROM contains up to 4 quarter-quadrangles of a USGS 7.5 minute quadrangle, where a quarter-quadrangle is included IF it's coverage includes any portion of the Twin cities 7 county area. The orthophotos are in UTM, Zone 15, NAD83 projection. Each image is approximately 120 Mb, with a .6 meter image pixel, and available in TIFF format. There are a total of 76 CD-ROMs plus one CD-ROM that contains one metadata record for the dataset and a header file (.hdr) for each image. These DOQs were produced using the USGS DOQ specifications except for the scan resolution (pixel size is .6m rather than 1 meter) and the file format. The original imagery was collected at 20,000 ft and centered on USGS quarter-quads. This dataset is available for direct use via the MnGeo Image Server.

Orthoimagery combines the image characteristics of a photograph with the geometric qualities of a map. For this dataset, the natural color orthoimages were produced at 0.3-meter pixel resolution (approximately 1-foot). The design accuracy is estimated not to exceed 3-meter diagonal RMSE (2.12m RMSE in X or Y). Each orthoimage provides imagery for a 1500-meter by 1500-meter block on the ground. The projected coordinate system is UTM with a NAD83 datum. There is no image overlap between adjacent files. The naming convention for the original tiles is based on the U.S. National Grid (USNG), taking the coordinates of the SW corner of the orthoimage. [Note: this metadata record was reformatted at the Minnesota Land Management Information Center from the record originally posted on the USGS Seamless Server - several of the fields including the Bounding Coordinates, Transfer Format Name, and Lineage fields were changed to reflect LMIC's data delivery option.]

2006 color Ramsey (stp2006)

The National Elevation Dataset (NED) is the primary elevation data product produced and distributed by the USGS. The NED provides the best available public domain raster elevation data of the conterminous United States, Alaska, Hawaii, and territorial islands in a seamless format. The NED is derived from diverse source data, processed to a common coordinate system and unit of vertical measure. All NED data are distributed in geographic coordinates in units of decimal degrees, and in conformance with the North American Datum of 1983 (NAD 83). All elevation values are provided in units of meters, and are referenced to the North American Vertical Datum of 1988 (NAVD 88) over the conterminous United States. The vertical reference will vary in other areas. NED data are available nationally at resolutions of 1 arc-second (approx. 30 meters) and 1/3 arc-second (approx. 10 meters), and in limited areas at 1/9 arc-second (approx. 3 meters). At present, the bulk of Alaska is only available at a 2 arc-second (approx. 60 meters) resolution, owing to a lack of higher resolution source data, though some areas are available at resolutions of 1 and 1/3 arc-second with plans for significant upgrades of the state over the next five years. The NED is updated on a nominal two month cycle to integrate newly available, improved elevation source data.

1991 bw USGS (doq)

A digital orthophoto is a raster image of remotely sensed data in which displacement in the image due to sensor orientation and terrain relief have been removed. Orthophotos combine the image characteristics of a photograph with the geometric qualities of a map. The primary digital orthophotoquad (DOQ) is a 1-meter ground resolution, quarter-quadrangle (3.75-minutes of latitude by 3.75-minutes of longitude) image cast on the Universal Transverse Mercator Projection (UTM) on the North American Datum of 1983 (NAD83). The geographic extent of the DOQ is equivalent to a quarter-quad plus overedge. The overedge ranges a minimum of 50 meters to a maximum of 300 meters beyond the extremes of the primary and secondary corner points. The overedge is included to facilitate tonal matching for mosaicking and for the placement of the NAD83 and secondary datum corner ticks. The normal orientation of data is by lines (rows) and samples (columns). Each line contains a series of pixels ordered from west to east with the order of the lines from north to south. The standard, archived digital orthophoto is formatted as four ASCII header records, followed by a series of 8-bit binary image data records. The radiometric image brightness values are stored as 256 gray levels ranging from 0 to 255. The metadata provided in the digital orthophoto contain a wide range of descriptive information including format source information, production instrumentation and dates, and data to assist with displaying and georeferencing the image. The standard distribution format of DOQs will be JPEG compressed images on CD by counties or special regions. The reconstituted image from the CD will exhibit some radiometric differences when compared to its uncompressed original but will retain the geometry of the uncompressed DOQ.

2003 color FSA (fsa)

This data set contains photographic information obtained for the National Agricultural Imagery Program (NAIP) and is comprised of scanned photographs that were acquired on color positive film. Acquisition was leaf-on with mature crops prior to harvest. Images have been orthorectified. NAIP imagery is quarter-quadrangle centered to provide consistent and repeatable coverage. The quarter-quad photos have been mosaicked into MrSID format county files. (Note that the Farm Services Agency provided one metadata record per MrSID county file; the Land Management Information Center created this metadata record to describe the whole data set. For information that FSA did not provide, the metadata for Minnesota's NAIP 2002 imagery can serve as a general guide to the NAIP program procedure -- some of the specific processing steps or accuracy assessments may differ from the 2003 program: http://www.lmic.state.mn.us/chouse/metadata/naip02.html )

2008 cir FSA (cir2008)

This data set contains 4-band (natural color plus infrared) imagery from the National Agricultural Imagery Program (NAIP). NAIP acquires digital ortho imagery during the agricultural growing seasons in the continental U.S. A primary goal of the NAIP program is to enable availability of ortho imagery within one year of acquisition. The source files are 1 meter ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy of within +/- 5 meters of reference digital ortho quarter quads (DOQQ's) from the National Digital Ortho Program (NDOP) or from NAIP. The tiling format of NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 300 meter buffer on all four sides. NAIP quarter quads are formatted to the UTM coordinate system using NAD83. NAIP imagery may contain as much as 10% cloud cover per tile. This file was generated by compressing NAIP quarter quadrangle tiles that cover a county. JPEG2000 compression was used. Target values for the compression ratio are (15:1). (Note: The Land Management Information Center has created this metadata record to describe the entire NAIP2008 dataset, using information from Farm Service Agency metadata. Each county file is accompanied by the original FSA metadata for that county.)
