Hello all,
I just received notice that MEGIS has obtained and posted for download
some large scale (2’ interval) topographic contour data for a number of
towns. The data was received from FEMA. I thought this information was
worthy of passing along on the GeoLibrary-L even if some of you may get the
MEGIS notice separately as this is an exciting data availability announcement.
Here’s a data intro from the metadata:
Description:
Abstract:
CONTOURS_2FT contains 2 foot interval contour lines
for the coastal areas of York and Cumberland Counties
from Old Orchard Beach
to Harpswell. The contour lines were one of several data sets created from
LiDAR collected in November 2006 by the Sanborn Map Company.
Purpose:
The Contours were originally derived from the LiDAR
data sets, including Bare Earth and a Gridded DEM support Camp
Dresser and McKee's continued
development of updated Digital Flood Insurance Rate Maps and flood insurance
studies for coastal areas located in Cumberland
and York Counties, Maine. The contours were created primarily
for determining areas of potential flooding. They are also useful to determine
drainage, for hydrology studies, for determining slope and for delineating
watersheds.
See below for the towns:
CONTOURS_2FT (2
foot contours) have been ADDED to the MEGIS internet Data Catalog for parts of
the following towns: Bath, Brunswick, Cape Elizabeth, Chebeague
Island, Cumberland,
Durham, Falmouth,
