State of Ohio Office of Information Technology, Ohio Geographically Referenced Information Program20121217UnknownMercer_cir_100x.sidraster digital fileColumbus, OHOGRIPThe 2012 OSIP digital orthoimagery was collected during the months of March and April (leaf-off conditions). The MrSID Images covering each county at a 12-inch pixel resolution have been created at a 20:1 compression ratio. At a 20:1 compression ratio, the resulting MrSID file size will average approximately 2GBs in size (dependent upon county size). In addition to the 20:1 compression SIDs, each county has also received a higher compression SID (100:1). The delivery of the countywide 12-Inch MrSID Images are based upon the geotiffs that were delivered to each individual county. In some cases, additional geotiffs (from surrounding counties) may have been added to enhance the visual depiction of the SID file.The state of Ohio has a goal to develop and maintain a seamless statewide base map, referred to as OSIP (Ohio Statewide Imagery Program). OSIP is an initiative partnered through several State Agencies (i.e. ODOT, ODNR, OEPA) through OGRIP. USGS is also a partner. Data from this project forms the foundation of the statewide base map, and was developed primarily to support multi-use applications, including homeland security, emergency management, economic development, and the business of government.201203092012031020120311201203132012031420120328ground conditionAs needed-84.822553-84.41419340.74842640.343205NoneRasterOrthophotononeUnited StatesOhioOGRIPThis data may be used by the requested party for stated purposes and should not be re-distributed.This data is for planning purposes only and should not be used for legal or cadastral purposes.OGRIPGIS Managermailing and physical address

This imagery was orthorectified to the existing LiDAR terrain data obtained for OSIP 1 and the ground control survey.The Leica ADS80-SH81/82 Airborne Digital Sensor is a push-broom geometry sensor, collecting 12-bit data with 12,000 pixel swath coverage with up to a 5-centimeter spatial resolution. The sensor is capable of collecting multiple spectral bands and angles simultaneously. Leica’s ADS80 collects seven bands of imagery simultaneously: three panchromatic CCD lines capture information in the forward, nadir and backward views from the aircraft, while four multispectral lines capture data in the red, green, blue, and near color infrared band. The imagery for this task order was acquired using the Leica ADS80-SH81/82 multispectral scanner. The ADS80-SH81/82 utilizes the Leica’s IPAS20 direct positioning and orientation system that is based on airborne GPS and inertial measurement unit (IMU) technology. The IPAS20 data were reduced using Leica’s IPAS Pro software package (V1.3). All of the source imagery was processed using the Leica XPRO (V5.0.1) software package. This package provides the capability to perform digital image processing, aerial triangulation, and image rectification. The strips of imagery were ortho rectified to newly collected LiDAR digtial elevation model (DEM) data. The individual rectified strips of ortho rectified imagery were then mosaicked together to form a seamless imagery database over the entire task order area using the OrthoVista software (V4.5) by Inpho GmbH. The final digital orthophoto imagery (DOI) were extracted using OrthoVista.20120227Woolpert, Inc.Geospatial Servicesmailing and physical address
