Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 26, 2026 | Last Modified: 2012-05-02T00:00:00.000+00:00
This dataset consists of 0.5-meter pixel resolution, four band orthoimages covering the Humboldt Bay area. An orthoimage is remotely sensed image data in which displacement of features in the image caused by terrain relief and sensor orientation have been mathematically removed. Orthoimagery combines the image characteristics of a photograph with the geometric qualities of a map. Each orthoimage provides imagery over a DOQQQ with a 100-meter image overlap between adjacent files. The projected coordinate system is UTM Zone 10 North with a NAD83 datum. This data depicts geographic features on the surface of the earth. It was created to provide easily accessible geospatial data which is readily available to enhance the capability of Federal, State, and local emergency responders, as well as plan for homeland security efforts. This data also supports The National Map. Original data are in .img and .ige (ERDAS Imagine and ERDAS Imagine Large Raster Spill file) format with associated browse graphics, .his files, and metadata in text format.
