Talking to a friend of mine in Hawaii and I am from New Mexico. My question to you all is to see if there is a land use/land cover dataset for Hawaii?
I poked around on the State of Hawaii GIS site but most of the layers were too general or too old.
Hope that helps!

NOAA's Coastal Services Center now has 2.4 meter land cover data for all eight of the main islands of Hawaii. Here is the link to the Coastal Change Analysis Program (CCAP) high-resolution land cover download page:
Select from the drop down menu on the right.
We've got some NLCD 2001 data from the USGS on WeoGeo.
If you look at all the land cover data we have for Hawaii, you may see something you need:
We've got hundreds of mostly free land cover datasets from around the world.
