shrug-l: Impervious land cover layer

[Jones, Rebekah D]

Do you mean inaccurate as in low/poor resolution, or inaccurate as in out-of-date, or both?

The 100-meter resolution map can be downloaded here: https://nationalmap.gov/small_scale/mld/impe100.html
There's also a tool that the user can use to define an area and analyze impervious surfaces: https://coast.noaa.gov/digitalcoast/tools/isat.html (more on that here: https://learn.arcgis.com/en/projects/calculate-impervious-surfaces-from-spectral-imagery/lessons/calculate-impervious-surface-area.htm)

Subject: shrug-l: Impervious land cover layer

Hello,

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.
Any suggestions for where to find such a layer other than the NLCD derived one?

Thanks,
Janis Morrow
