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, Freeport, Harpswell, Long
Island, Old Orchard Beach, Phippsburg, Portland, Saco, Scarborough, South
Portland, Topsham, West Bath, and Yarmouth.
