Title: Landsat 7 ETM/1G satellite imagery - Hawaiian Islands cloud-free mosaics
Short Name: 8main_hawaii_landsat_mosaic
Status: Completed
Publication Date: 2002-01-31

Cloud-free Landsat satellite imagery mosaics of the islands of the main 8 Hawaiian Islands (Hawaii, Maui, Kahoolawe, Lanai, Molokai, Oahu, Kauai and Niihau). Landsat 7 ETM (enhanced thematic mapper) is a polar orbiting 8 band multispectral satellite-borne sensor. The ETM+ instrument provides image data from eight spectral bands. The spatial resolution is 30 meters for the visible and near-infrared (bands 1-5 and 7). Resolution for the panchromatic (band 8) is 15 meters, and the thermal infrared (band 6) is 60 meters. The approximate scene size is 170 x 183 kilometers (106 x 115 miles). A Nadir-looking system, the sensor has provided continuous coverage since July 1999, with a 16-day repeat cycle. The Level 1G product is radiometrically and geometrically corrected (systematic) to the user-specified parameters including output map projection, image orientation, pixel grid-cell size, and resampling kernel. The correctional gorithms model the spacecraft and sensor using data generated by onboard computers during imaging. Sensor, focal plane, and detector alignment information provided by the Image Assessment System (IAS) in the Calibration Parameter File (CPF) is also used to improve the overall geometric fidelity. The resulting product is free from distortions related to the sensor (e.g., jitter, view angle effect), satellite (e.g., attitude deviations from nominal), and Earth (e.g., rotation, curvature). Residual error in the systematic L1G product is less than 250 meters (1 sigma) inflat areas at sea level. The systematic L1G correction process does not employ ground control or relief models to attain absolute geodetic accuracy.


The Landsat Project is a joint initiative of the U.S Geological Survey(USGS) and the National Aeronautics and Space Administration (NASA) to gather Earth resource data using a series of satellites. NASA was responsible for developing and launching the spacecrafts, while the USGS is responsible for flight operations, maintenance, and management of all ground data reception, processing, archiving, product generation, and distribution. The primary objective of the Landsat Project is to ensure a collection of consistently calibrated Earth imagery. Landsat's GlobalSurvey Mission is to establish and execute a data acquisition strategy that ensures repetitive acquisition of observations over the Earth's landmass, coastal boundaries, and coral reefs; and to ensure the data acquired are of maximum utility in supporting the scientific objectives of monitoring changes in the Earth's land surface and associated environment.

Data Quality



Horizontal Positional Accuracy:

The nominal resolution is achieved within 30 degrees of nadir. Geodetic accuracy is monitored using calibration scenes containing ground control points. Scenes are first radiometrically and geometrically corrected. Control point locations are then measured on the processed imagery and compared to known ground locations. Any terrain effects are removed analytically in the comparison. The post-calibration geodetic accuracy of systematic ETM+ products is approximately 50 meters which is much better than 250 meter specification placed on the system.Band-to-band registration measures the relative alignment of the eight ETM+ spectral bands after processing to Level 1Gs. Measured registration between the primary and cold focal planes in the line direction is typically 0.08-0.10 pixels, well below the design specification limit of 0.17 pixels.Image registration accuracy is measured using cloud-free images of two separate calibration sites. One meter resolution DOQs were mosaicked and reduced to 15 meter resolution. The image registration assessment was performed in two ways. First, the ETM+ images were compared against the DOQ reference images. This provides a measure of image distortion relative to an absolute reference. The 1 sigma accuracy for registration to DOQs is 4.3 meters along scan and 4.2 meters across scan. Second, two ETM+ scenes were cross correlated. This provides a measure of image distortion that changes scene-to-scene although systematic calibration distortions may cancel out. The 1 sigma accuracy for ETM+ to ETM+ registration is 3.2 meters along scan and 1.9 meters across scan.; Quantitative Value: 50 meters, Test that produced the value: Meters

Vendor Product Name - Enhanced Thematic Mapper Plus (ETM+)Vendor Product Description - The ETM+ instrument provides image datafrom eight spectral bands (band designations). The spatial resolution is 30 meters for the visible and near-infrared (bands 1-5 and 7).Resolution for the panchromatic (band 8) is 15 meters, and the thermal infrared (band 6) is 60 meters. The approximate scene size is 170 x 183 kilometers (106 x 115 miles).Processing Level Name - 1GProcessing Level Description - Systematic Correction (Level 1G) includes both radiometric and geometric correction. Image data is provided in rescaled 8-bit (DN) values. The scene will be rotated, aligned, and georeferenced to a user-defined map projection. Geometric accuracy of the systematically corrected product should be within 250 meters (1 sigma) for low-relief areas at sea level.
