2010 Southeast Michigan Imagery Project

 
AirplaneLogo_Modified


Background

The 2010 flight is a coordinated effort, based on the model we used in 2005, to acquire digital orthoimagery for the Southeast Michigan region. SEMCOG lead the partnership in cooperation with Livingston, Macomb, Monroe, Oakland, St. Clair, Washtenaw, and Wayne Counties, Detroit Water and Sewerage Department, and the United States Geological Survey.

The contract to acquire and process the imagery was awarded to 
Woolpert.  They acquired three-band, true color, plus Color Infrared (CIR) imagery. Click here to learn more about CIR imagery. The base resolution for the seven county region is one-foot pixel resolution.  Monroe, Oakland, Washtenaw and Wayne Counties have opted to buy up to six-inch pixel resolution.

No Cost LiDAR - Light Detection and Ranging
 
SEMCOG was awarded an ARRA (American Recovery and Reinvestment Act) grant to acquire LiDAR data at 1.5-meter average post spacing for the Livingston, Macomb, Monroe, and St. Clair Counties in Spring 2010. This will align with the 2008 LiDAR acquired for Oakland County and the 2009 LiDAR captured for Washtenaw and Wayne Counties. With the addition of this LiDAR data, we will have a current, seamless LiDAR dataset. As well, the LiDAR will be used to support the 2010 imagery project and future applications. Having a large regional dataset will support applications that don’t recognize political boundaries, allowing all seven counties to benefit from the additional LiDAR data. This project includes collecting LiDAR at 1.5 meter post spacing for the entire four-county, 2,351-square-mile area during leaf-off conditions. All of this data will be provided to the counties at no cost.

LiDAR data is proving to be one of the most useful data sets, in conjunction with the CIR imagery, in terms of the attributes that it provides. LiDAR data not only stores accurate coordinate data (X, Y and Z) allowing for the creation of three dimensional terrains, but it also provides a number of additional attributes which can be queried for feature verification. LiDAR data can be used to create a number of datasets and support applications, such as building footprints, impervious surface data and analysis, contours lines, drain office apportionment, stream/drain profiles, and emergency management plume modeling.
