Imagery for the Vegetation Mapping Inventory Project for Haleakala National Park
2012. Imagery for the Vegetation Mapping Inventory Project for Haleakala National Park
Digital Globe Quickbird and Worldview2 imagery of HALE were obtained from the US Department of Agriculture – National Resource Conservation Service (USDA - NRCS). The imagery was segmented in eCognition software and both the imagery and the segments were taken to the field to support the calibration trip. Following the calibration trip, KGA labeled the segments using the imagery, ancillary data sets, and classification and regression tree analysis to create a preliminary map. The preliminary map was reviewed by PACN staff and assessed in the field by KGA and HALE staff during the validation trip. Manual edits based on the comments and results from the validation trip were made to the preliminary map to create HALE’s draft vegetation map. Multiple imagery datasets were used in the HALE vegetation mapping project, including Quickbird 4 band optical imagery collected between 2004 and 2005, Worldview2 8 band optical imagery captured between 2010 and 2012, Landsat 7 band imagery from 2003 and, interferometric synthetic aperture radar imagery flown by Intermap.
