The project is divided into three geographic areas: Area 1 2011 - Indiana central counties: St. Joseph, Elkhart, Starke, Marshall, Kosciusko, Pulaski, Fulton, Cass, Miami, Wabash, Carroll, Howard, Clinton, Tipton, Boone, Hendricks, Marion, Morgan, Johnson, Monroe, Brown, Bartholomew, Lawrence, Jackson, Orange, Washington, Crawford, and Harrison. Area 2 2012 - Indiana eastern counties: LaGrange, Steuben, Noble, DeKalb, Whitley, Allen, Huntington, Wells, Adams, Grant, Blackford, Jay, Hamilton, Madison, Delaware, Randolph, Hancock, Henry, Wayne, Shelby, Rush, Fayette, Union, Decatur, Franklin, Jennings, Ripley, Dearborn, Ohio, Scott, Jefferson, Switzerland, Clark, and Floyd. Area 3 Scheduled for 2013 - Indiana western counties: Lake, Porter, LaPorte, Newton, Jasper, Benton, White, Warren, Tippecanoe, Fountain, Montgomery, Vermillion, Parke, Putnam, Vigo, Clay, Owen, Sullivan, Greene, Knox, Daviess, Martin, Gibson, Pike, Dubois, Posey, Vanderburgh, Warrick, Spencer, and Perry. Area 1 data was acquired in 2011. Area 2 data was acquired in 2012. According to the scope of this project, additional data collection is scheduled for Area 3 in 2013. Projection Reference: EPSG2965: NAD83 Indiana East (ftUS) and EPSG2966: NAD83 Indiana West (ftUS). Note: The ground control survey performed to support the Orthophotography and LiDAR data used the NAD 1983 NSRS2007 (ftUS) projection. To facilitate usability by multiple software versions the Orthophotography and LiDAR is only referenced to NAD 83, and the file projection/header information was written to the files using ERDAS IMAGINE. Purpose: The State of Indiana's goal is to develop and/or update certain geospatial data sets for use by state government agencies, other levels of government, academia, and the general public, and to provide these data sets for inclusion to the IndianaMap. The IndianaMap is a resource for geographic information technology users inside Indiana and beyond. The IndianaMap is an initiative of the Indiana Geographic Information Council, Inc. (IGIC), Indiana's statewide GIS coordination council. Data from this project forms the foundation of the base map, and were developed primarily to support multi-use applications, including homeland security, emergency management, economic development, and the business of government. Funds for the statewide orthophotography program come from state agencies, local governments, and grants. Supplemental_Information: CONTRACTOR: Woolpert, Inc.

Process_Step: Process_Description: Block 7(partial) and 8 - Using an Optech Gemini LiDAR system, 152 flight lines of high density data, at a nominal pulse spacing (NPS) of 1.5 meter (1.0 meters for Floyd and Deerborn Counties)and Blocks 5, 6, and 7(partial) -Using a LH Systems ALS70 LiDAR system, 205 flight lines of high density data, at a nominal pulse spacing (NPS) of 1.5 meter were collected over Indiana(approximately 8662 square miles). Multiple returns were recorded for each laser pulse along with an intensity value for each return. A total of thirty-nine (39) missions were flown January 31, 2012 April 02,2012. A single airborne global positioning system (GPS) base station was used in support of the LiDAR data acquisition. 248 ground control points were surveyed through static methods. The geoid used to reduce satellite derived elevations to orthometric heights was Geoid09. The horizontal datum used for this survey is North American Datum 1983 (NSRS2007), Indiana State Plane Coordinate System, East Zone, and expressed in US Survey Feet. The vertical datum used for this survey is North American Vertical Datum 1988 (NAVD88), and expressed in US Survey Feet. Airborne GPS data was differentially processed and integrated with the post processed IMU data to derive a smoothed best estimate of trajectory (SBET). The SBET was used to reduce the LiDAR slant range measurements to a raw reflective surface for each flight line.

The calibration range consists of a large building and runway. The edges of the building and control points along the runway have been located using conventional survey methods. Inertial measurement unit (IMU) misalignment angles and horizontal accuracy are calculated by comparing the position of the building edges between opposing flight lines. The scanner scale factor and vertical accuracy is calculated through comparison of LiDAR data against control points along the runway. Field calibration is performed on all flight lines to refine the IMU misalignment angles. IMU misalignment angles are calculated from the relative displacement of features within the overlap region of adjacent (and opposing) flight lines. The raw LiDAR data is reduced using the refined misalignment angles.

The GPS and IMU data was post processed using differential and Kalman filter algorithms to derive a best estimate of trajectory. The quality of the solution was verified to be consistent with the accuracy requirements of the project.

Then, the flight lines were compared to adjacent flight lines for any mismatches to obtain a homogenous coverage throughout the project area. The point cloud underwent a classification process to determine bare-earth points and non-ground points utilizing "first and only" as well as "last of many" LiDAR returns. This process determined bare-earth points (Class 2), noise (Class 7), water (Class 9) ignored ground (Class 10), unclassified data (Class 1), overlap points (Class 12), and bridges (Class 13). The bare-earth (Class 2 - Ground) LiDAR points underwent a manual QA/QC step to verify that artifacts have been removed from the bare-earth surface. The surveyed ground control points are used to perform the accuracy checks and statistical analysis of the LiDAR dataset.

Breaklines defining water bodies and streams were compiled for this task order. The breaklines were used to perform the hydrologic flattening of water bodies, and gradient hydrologic flattening of double line streams. Lakes, reservoirs and ponds, at a nominal minimum size of two (2) acres or greater, were compiled as closed polygons. The closed water bodies were collected at a constant elevation. Rivers and streams, at a nominal minimum width of 100 feet (30.5 meters), were compiled in the direction of flow with both sides of the stream maintaining an equal gradient elevation. The hydrologic flattening of the LiDAR data was performed for inclusion in the National Elevation Dataset (NED).
