<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are looking for an already existing data set for Florida of impervious surfaces. Something that includes roads, buildings, parking lots, etc. We are looking for data already created, not suggestions on how to make one ourselves. We
are aware of an impervious dataset derived from the National Land Cover Dataset, but we are not finding it very accurate.<o:p></o:p></p>
<p class="MsoNormal">Any suggestions for where to find such a layer other than the NLCD derived one?<o:p></o:p></p>
