Item Identification

Title: Great Lakes Restoration Initiative: Lake Superior Imagery
Short Name: 2010_epa_glri
Status: Completed
Publication Date: 2008-06-10

The data contained in this file contain hydrographic and topographic data collected by the Fugro LADS Mk II system along the Lake Superior coast of Minnesota, Wisconsin and Michigan. FLI was contracted under Fugro Earth Data Inc (FEDI) by NOAA Office for Coastal Management (OCM) to collect data under the Great Lakes Restoration Initiative. During standard bathymetric data collection digital imagery is collected for data verification. The specific images are georeferenced and joined into an overall mosaic. Digital Imagery was created on a tile by tile basis for all 91 tiles. This file is to be used for all Minnesota tiles, Wisconsin tiles and Michigan tiles 01-05

This data was collected as part of the Great Lakes Restoration Initiative (GLRI) an inter agency initiative lead by the Environmental Protection Agency (EPA) targeting areas with the most significant problems in the Great Lakes region.



Supplemental Information:

Digital imagery covers the majority of the survey area. During sortie 7 digital images were not collected due to a hard drive failure. The area covered by sortie 7 contains gaps in the digital image coverage and therefore there are gaps in the digital mosiacs over some tiles. Specific gaps in the imagery can be seen in the Report of Survey.

Process Steps

Process Step 1

CC ID: 665345

This data was collected using the LADS Mk II bathymetric Lidar survey system. It is owned by Fugro LADS Corp. and was operated by Fugro LADS Inc. The system collects bathymetric/topographic data at 1kHz. The system also collects digital imagery at 1Hz. Aircraft position information is collected with Wide Area Differential (WADGPS) through Omistar and is logged with GrafNav. The LADS Mk II system operated on a stabilized platform. Raw data are copied from the LADS Air System (AS) to the LADS Ground System (GS) where post processed GPS is applied as the raw data is processed, producing a 3-D position for each waveform in the dataset. Digital images were combined into a digital mosaic with the use of the LADS Mosaic Build Tool and exported as a geotiff. Sun angle, low light and other environmental conditions were automatically removed from the mosaic building process. Each mosaic/geotiff was georeferenced to UTM Zone 15 or 16 North using Global Mapper and exported in ECW format. The ECW imagery was imported into ERDAS Imagine and converted to .img format. The .img files were processed into four large image mosaicks, with the overlap values set to the minimum pixel value.
