New England topographical map
This is the latest release of the downloadable topo map for Maine, Massachusetts, New Hampshire, Vermont.
Visit this forum if you have any questions or comments regarding this map.
This free map is as good, if not better than any commercial maps you can buy for your Garmin GPS. Doing a map of this quality requires a considerable amount of computing power, disk space and Internet bandwidth. Please consider supporting this project.

Data Sources
The GIS data sets utilized for creating these maps were obtained from the following sources:
The Census Bureau's MAF/TIGER Enhancements Program
seeks to achieve a high level of map coordinate accuracy in TIGER by
acquiring and using, as a first priority among data sources, digital
files prepared and provided by state, local and tribal governments. The
Census Bureau will have its contractors (the folks who will actually
perform the much needed TIGER realignment work) use all high-accuracy
state, local and tribal government GIS files (that meet or exceed our
street center-line spatial accuracy requirement of 7.6 meters and are
provided without royalty or copyright restriction. USGS National Geographic Names Information System (GNIS) - http://geonames.usgs.gov/pls/gnispublic The U.S. Board on Geographic Names is a Federal body
created in 1890 and established in its present form by Public Law in
1947 to maintain uniform geographic name usage throughout the Federal
Government. The Board comprises representatives of Federal agencies
concerned with geographic information, population, ecology, and
management of public lands. Sharing its responsibilities with the
Secretary of the Interior, the Board promulgates official geographic
feature names with locative attributes as well as principles, policies,
and procedures governing the use of domestic names, foreign names,
Antarctic names, and undersea feature names. USGS Dataset Elevation Dataset (NED) - http://ned.usgs.gov/ The USGS National Elevation Dataset (NED) has been
developed by merging the highest-resolution, best quality elevation
data available across the United States into a seamless raster format.
NED is the result of the maturation of the USGS effort to provide
1:24,000-scale Digital Elevation Model (DEM) data for the conterminous
US and 1:63,360-scale DEM data for Alaska. The dataset provides
seamless coverage of the United States, HI, AK, and the island
territories. NED has a consistent projection (Geographic), resolution
(1 arc second), and elevation units (meters). The horizontal datum is
NAD83, except for AK, which is NAD27. The vertical datum is NAVD88,
except for AK, which is NAVD29. NED is a living dataset that is updated
bimonthly to incorporate the "best available" DEM data. As more 1/3 arc
second (10m) data covers the US, then this will also be a seamless
dataset. USGS National Hydrography Dataset (NHD) - http://nhd.usgs.gov/index.html
US Census Bureau Topologically Integrated Geographic Encoding and Referencing (TIGER) - http://www.census.gov/geo/www/tiger/index.html
The National Hydrography Dataset (NHD) is a comprehensive set of
digital spatial data that contains information about surface water
features such as lakes, ponds, streams, rivers, springs and wells.

The purpose of
this Data Catalog is to provide the public with access to the digital
geographic data produced by the GIS Executive Council, and Maine
GeoLibrary Board. The Data Catalog is hosted and maintained by the
Maine Office of GIS (MEGIS).
