Posted November 7, 200717 yr I know we have a lot of urban planning-mapping-Geopgraphy-Engineering students and/or professionals and/or 'geeks'; so here's a PSA for an on-going program to collect statewide imagery in the form of aerials and DEM's generated from LiDAR; which will be compatible with GIS and CADD. The northern counties are done and available for download, southern counties will be delivered by sometime next spring. [i think the aerial images are available in Google Earth] Main site: http://oit.ohio.gov/SDD/ESS/Ogrip/ImageryProgram.aspx Program Description: http://oit.ohio.gov/SDD/ESS/Ogrip/pdf/OSIP%20Program%20Description.pdf Downloads: http://gis1.test.oit.ohio.gov/geodatadownload/osip.aspx PRODUCTS AVAILABLE FOR DOWNLOAD -------------------------------------------------------------------------------- IMAGERY: 1FT Color County Mosaic MrSID format ~30:1 compression 6IN Color County Mosaic MrSID format ~100-150:1 compression DIGITAL ELEVATION MODEL (DEM) TILED 2.5 Foot Grid DEM - ESRI GRID Format Archived by County TILED 2.5 Foot Grid DEM - ASCII Format Archived by County COUNTYWIDE 2.5 Foot Grid DEM - ESRI GRID Format As Available LiDAR TILED ~2 Meter LiDAR 1st and Last returns LAS Format Archived by County TILE LAYOUTS: State Plane North 1FT products (5000' x 5000') State Plane North 6IN products (2500' x 2500') State Plane South 1FT products (5000' x 5000') State Plane South 6IN products (2500' x 2500') State Plane North CIR products (15000' x 15000')
