You-all may already be aware of this, but here is the url for the FL GAP 
(lancover from Landsat plus ancillary info)--

<http://www.wec.ufl.edu/coop/GAP/>

The FL-GAP map was based on fine-resolution remote sensing data (30m), but 
begs the question--is it or a similar program going to provide for an 
update, say every few years or so?

There is also a USGS remote-sensing landcover project, but at rather coarse 
(1 km) resolution.  Some Water MDs have begun to acquire airborne imagery 
at very-fine resolution, which should allow for the generation of detailed 
(1-2 m) veg maps of their individual districts, as their priorities permit.

In general, landcover from purely remote-sensing approaches is 
vegetation-canopy dependent (short grass is short grass regardless of 
whether it is mowed by animal or rider-mower; oak-hammock is oak-hammock 
regardless of whether the groundcover is partridgeberry or tradescantia; a 
highway shoulder sporting phlox is distinct from nearby shoulder having 
plain bahiagrass whether you like it or not, etc.).  A mixed RS-GIS 
approach using satellite/airborne periodic updates plus soil-type/DEM/hydro 
GIS layers might be useful for discrimination of certain natural-community 
types (such as gall, seep, rockland types as described by FNAI, etc.) that 
might be difficult (or at least expensive) to separate by RS canopy-top 
info alone.  Relationships between different classification schemes (as 
published by federal, state, water-MDs) tend to become increasingly 
problematical at finer grades of landcover distinction (LULC 3+) that may 
split hairs down to species, subspecies, or even further level (from "them 
thar palmetters" to "Serenoa repens vs Sabal etonia" to "Blue vs Green S. 
repens"), not to mention the special distinctions (hybrids, management 
practices, etc.) within "disturbed/transitional" greenspaces--restoration 
areas, impacted areas, plantation forests, picnic-parks, orchards, and 
invasive-exotic infestations.  Regardless of source, a landcover or veg map 
will also have to come with a sufficient amount of documentation to be 
useful to another project; most recent GIS-layer products by various 
agencies and research-NGOs incorporate proper metadata practices to some 
degree, but this can be an "unknown and unknowable" problem for historical 
datasets.

If anyone has assembled a catalog of FL statewide/local landcover and/or 
veg-map GIS datasets (published-and-available ones) produced by multiple 
agencies (i.e., not just their own holdings), including at least a brief 
bit of metadata (what-where-when), please reply to me if not the whole 
shruglist.

Good hunting,
