GIS > Orthophotography/LiDAR Orthophotography/LiDAR

Orthophotography is an aerial photo which can be used as a map to:

  • Measure Distance
  • Calculate Area
  • Determine Shapes of Features
  • Calculate Directions
  • Determine GPS Coordinates
  • Perform Change Detection

The state of Indiana is well into a three-year project to provide 1-foot resolution orthophotography and elevation data for the entire state of Indiana. The imagery and elevation data is used by numerous state agencies, and is shared with county governments for use in applications such as tax assessment, property management, economic development and flood control analysis. These data are also available to the public via the IndianaMap.

A south-to-north acquisition was performed in 2011 to complete approximately 30 of the 92 counties in the center column of the state. The eastern counties were flown in 2012 and the remaining western counties will be flown in spring 2013.  The statewide program also includes new U.S. Geological Survey (USGS) compliant light detection and ranging (LiDAR) elevation data.

Full program.

Uses and Benefits

Optional Digital Orthoimagery

As an option, additional project partners including counties, cities/towns, and others may buy-up to 6-inch or 3-inch pixel resolutions. Approximately 25 cities and counties have taken advantage of this option resulting in higher resolution data that is available to all.

LiDAR is digital elevation data that can be used in conjunction with orthophotography.  Uses include:

 

  • Flood analysis
  • Forestry management
  • Land cover/land use determination
  • Impermeable surfaces identification
  • Transportation planning
  • Cell tower and wind turbine placement
