Islands of Kaho‘olawe, Lana‘i, Moloka‘i, Ni‘ihau

Kaho‘olawe

• General Data: USGS Hawai'i Clearinghouse: Kaho‘olawe Data
• area extents are around 17.6 * 11.6 km
• extracted a 2k*2k BT from 10m DEM, added it to the BT repository
• from the same LandSat7 delivery that we used for the Big Island, there is a rather cloudy image of Kaho‘olawe:
  
• 2002.06, i used PhotoShop to remove the clouds as well as i could and align it to the extracted BT
• the result is kaho_2048.jpg, suitable for draping in Enviro:
  
• SOEST has Shoreline Imagery and Data for Kaho‘olawe
  • Almost covers the island, leaving just a triangle in the middle.  It might be possible to put together a good aerial coverage for the island using these, using the Emerge aerial to fill in the area in the middle?
  • Tried this January 2006, and found that there is still a rectangular gap with no aerial coverage, snapshot:
    

Lana‘i

Ni‘ihau

• islands extents are approx. 20.8 * 27.7 km
• General Data: USGS Hawai'i Clearinghouse: Ni‘ihau Data
• NOAA aerials
  • at 85cm, imagery covers an area of around 24470 * 32588 pixels
  • image extents are (370826.7, 2408667.9), ( 21093.6, 27958.2)
  • January 2005, i produced a cleaned-up edit of this imagery, resampled at 1.7m (12409 * 16446) with the colors balanced and other artifacts removed
  • a subsample (4k*4k) of the cleaned-up image is now in the Repository
• Scott Armstrong's Ni'ihau Photoreal Scenery in MSFS 2004 format (now offline?)
  • built from 10m DEM and NOAA aerials
  • it's really quite beautiful
