Abstract

These SPOT10 images of Maine are a statewide USA Select SPOTView product of the SPOT Image Corporation. The tonal balanced, 30'x30' frames are designed to be load-n-go into GIS and image processing systems. The source imagery is SPOT PAN, panchromatic 10 meter data. Images are orthorectified to an accuracy of 12 meters or better, and range in date from April 30, 1998 to September 7, 2001. Most images are from leaf-on periods, but a few are from late October and early December.

Purpose

For aerial orthoimagery over large areas or areas where no digital orthophotoquadrangles or other higher resolution orthophotography are available, and for remote sensing purposes.

Access Constraints

These data are LICENSED, not sold, and are available for share to all levels of government and state universities, and contractors working for those licensed categories, on government and university projects only. Distribution is prohibited unless license conditions are met and confirmed with the Maine Office of Geographic Information Systems.

Use Constraints

Users must assume responsibility in determining the usability of this data for their purposes. Digital maps retain the accuracy of their source materials. The best use of data mapped at scales of 1:500,000 and 1:250,000 is in statewide planning and studies; at 1:100,000 in regional planning and studies; at 1:62,500 and 1:24,000 in detailed studies and local planning; and at 1:12,000 and 1:5,000 or larger scales in parcel level studies and detailed local planning. In the use of Maine GIS data, please check sources, scale, accuracy, currentness and other available information. Please confirm that you are using the correct copy of both data and metadata from the Maine GIS Data Catalog. Updates, corrections, and feedback, incorporated in the Maine GIS database are made in accordance with "Data Standards for Maine Geographic Information Systems", 2002, and coordinated by MEGIS

Logical Consistency Report

The USA Select SPOT10 product for Maine was delivered in 30'x30' frames in GeoTIFF SPOTView product format. One half the size of a USGS 1:100,000 scale 30 x 60 minute series, the files are stored on the Maine GIS server in directories labeled <100k tile> -e and <100k tile>-w. A statewide image mosaic is served to Maine GIS SDE users as the MEGIS.Spot10 SDE layer.

Horizontal Positional Accuracy Report

The data follows SPOTView specifications for a positional (horizontal) accuracy of 12 meters or better with 90% confidence.

Series Name	SPOT Satellites
Issue Identification	SPOT 1, 2, 3, 4, 5
Other Citation Details	Four SPOT (Satellite Pour l'Observation de la Terre) satellites have been launched since 1986. Each satellite carries two electro-optical sensors. The panchromatic sensor acquires single-band imagery in 10-meter spatial resolution, while the multispectral sensor captures 20-meter imagery in three wavelengths-visible green, visible red, and near infrared. On March 23, 1998, SPOT4 was launched with two additional capabilities: image acquisition in the middle infrared wave length band, and the "Vegetation" sensor for daily monitoring of the entire Earth at 1km resolution. The "adjustable viewing angles" on the sensors allow SPOT to acquire side-to-side stereoscopic imagery for three-dimensional surface viewing. This also allows SPOT to acquire repeat imagery of any point on the earth every day. On board recorders store image data for later transmission when the satellites are out of ground station receiving range. SPOT 1, 2 and 4 continue providing commercial service. SPOT 5, scheduled for launch in 2001, includes major advancements: panchromatic imagery with 2.5 meter resolution in a 60x60 kilometer scene size; a "fore-aft" sensor suite for stereo image acquisition to produce high-quality digital elevation models; additional imaging modes -5m panchromatic, 10m multispectral/4 band, 120 km swath width.

Process Description

The USA Select product is a statewide tonal balanced, 30'x30' SPOTView product designed to be load-n-go into GIS and image processing systems. The source imagery is SPOT PAN 10 m data. SCENE SELECTION: Fall/Winter/Spring (leaf-off) scenes were preferred, but summer (leaf-on) imagery was used if scene gaps were present. SCENE DATABASE: The "scenelat.shp" file delivered with the product contains ARC/VIEW shape files that include detailed information of the SPOT PAN scenes that were processed to create the final product. This file is unprojected. The "sceneutm.shp" file contains ARC/VIEW shape files that have the same information in UTM projection. The attached "sc_met.doc" describes the most commonly used fields of the scenes file. FRAMES: The dataset was provided as 30'x30' frames. These frames were defined as quadrants of the USGS 1 deg. x 1 deg. grid and were produced for all 30'x30' cells which intersect with the state boundary including coastal islands. Data file names on the delivered product were composed as follows: The 1st 3 digits refer to the Latitude and the 4th - 7th digits to the Longitude of the lower right corner of the 1 deg. by 1 deg. block in which it belongs. The 8th digit is the 30'x30' tile number as determined by the tile's position in the 1 deg. x 1 deg. block. Tile 1 is in the upper left, tile 2 in the upper right, tile 3 in the lower left, tile 4 in the lower right. File name example: N34W1094.TIF. The "framelat.shp" file contains ARC/VIEW shape files that indicate the extent and file name of each 30'x30' frame. This file is unprojected. The "frameutm.ahp" file contains ARC/VIEW shape files that indicate the same information in UTM projection. FILE FORMATS: Files are in GEOSPOT VERSION 4.1 format. File format consists of these files: framename.TIF - This is the imagery file, imagery is in GEOTIFF untiled format. This file is compliant with the TIFF version 6 specifications issued by Aldus/Adobe Corporation in June 1992. Contains the georeferencing tags compliant with the GeoTIFF specification 1.0 issued by NASA Jet Propulsion Laboratory in September, 1995. ASCII .DSC File - lists all files on media ASCII .REP File - the first file of each product is the Geospot Report File. It has the same name as the product and describes the content of the product it belongs to: product general information, structure definition (numbering and names of files), cartographic parameters and framing information. ASCII .HDR File - all pertinent georeferencing information for the image data including file sizes in pixels (columns) and lines (rows), pixel size, and map coordinates for georeferencing the upper left corner of the image file. ASCII .CLR File - prescribed standard lookup table for image display. Use of this file is optional. This file can also be used for pseudo-coloring an image or thematic map. ASCII .RSC File - the Raster Source Description File provides information about the sources of the raster file (origin, sensors.) SOFTWARE REQUIREMENTS: The dataset requires a software package capable of loading and displaying SPOTView raster images. Most major GIS (Geographic Information Systems) and IP (Image Processing) software that work in the geographic domain are capable of loading, translating, and ingesting SPOTView data. PROJECTION INFORMATION: This dataset is provided in UTM NAD83. ACCURACY: The provided dataset follows our SPOTView specifications for positional (horizontal) accuracy of 12 meters or better with 90% confidence.
