Title:

2010/11 UMRS Color Infrared Aerial Photo Mosaic

Geospatial_Data_Presentation_Form: raster digital data

Other_Citation_Details:

In 1989, UMESC and the Upper Mississippi River Restoration-Environmental Management Program (UMRR-EMP) began collecting aerial photos of the Upper Mississippi River System (UMRS) from Cairo, IL to Minneapolis, MN and the Illinois River from its confluence with the Mississippi near Grafton, IL upstream to Joliet, IL. In years past the extent was road/railroad to road/railroad. Starting in 2000, the area photographed was expanded to base-of-bluff to base-of-bluff. The data are stored in Universal Transverse Mercator (UTM) projection, zone 15 and North American Datum 1983 (NAD83).

Description:

Abstract:

The Upper Mississippi River Restoration-Environmental Management Program (UMRR-EMP) partnered with the U.S. Fish and Wildlife Service (USFWS) Region 3 to collect digital color infrared (CIR) aerial photography of Pools 1-13, Upper Mississippi River at 8"/pixel resolution and Pools 14 - Open River, Mississippi River and the Illinois River at 16”/pixel using a mapping-grade Applanix DSS439 digital aerial camera. The photography shall be at a minimum accuracy of 5-10 meters and allow for the development of orthorectified photo mosaics by U.S. Geological Survey – Upper Midwest Environmental Sciences Center (USGS-UMESC) for all or portions of the coverage area. The flights occurred during times of peak vegetation biomass, typically from late August through early September. The primary use of this photography is for the development of Land Cover / Land Use (LCU) databases of the UMRS by the USGS-UMESC. The photography and LCU databases are used in support of all stages of HREP project development and monitoring. In addition, the photography and maps are used for research and monitoring efforts conducted by the LTRM component in support of UMRR-EMP. The imagery is served over the internet as orthorectified pool mosaics by USGS-UMESC.

Purpose:

In 1989, UMESC and the Upper Mississippi River Restoration-Environmental Management Program (UMRR-EMP) began collecting aerial photos of the Upper Mississippi River System (UMRS) from Cairo, IL to Minneapolis, MN and the Illinois River from its confluence with the Mississippi near Grafton, IL upstream to Joliet, IL. In years past the extent was road/railroad to road/railroad. Starting in 2000, the area photographed was expanded to base-of-bluff to base-of-bluff. The data are stored in Universal Transverse Mercator (UTM) projection, zone 15 and North American Datum 1983 (NAD83).

Process_Step:

Process_Description:

Raw imagery is developed using Applanix PosPac MMS 5.4 (details like Mission Statistics are calculated, Histogram optimization, Lens Falloff corrections applied).

Process_Step:

Process_Description:

Rapid Orthos are generated, using 1/3 Arc Second DEMs, lens distortion correction, and POSPac Batch Global Navigation Satellite System (GNSS) processing in Applanix PosPac MMS 5.4 using ImageView and Applanix DSS Rapid Ortho

Process_Step:

Process_Description:

These rapid orthos are mosaicked using Erdas Imagine 2011's Mosaic Pro tool, Using most nadir seamline generation as a template, we are manually adjusting some seamlines to account for sun glare, lens flare and any unique features (bridges and islands) that can be captured by one image, the seams are further enhanced by a small amount of feathering (2-5 meters). The output is being saved as JPEG2000

Process_Step:

Process_Description:

Inpho OrthoVista 4.5.1 is being used to color balance the mosaics. The options being adjusted include, global tilting adjustment- adjust color- maximum grey difference 20 percent
