Cartography on the Web
- Google Maps
- This is my default mapping program, with an amazingly fast user
interface which lets you drag the map with your mouse.
Here is where I work.
- U.S. Geological Survey
- The USGS covers many topics in geology, mapping, and water resources.
- The National Map is an interactive
display of the entire country as a topographic map, with variable overlays.
- Maps are accessible through the
Digital Elevation Map index
- The University of New Hampshire has
1903 USGS maps of New England
- The University of Iowa serves
- TopoZone has adjustable-scale
USGS topographic maps for the entire United States online.
- Map Machine
- An interactive online atlas based on the National Geographic Society
Atlas of the World.
- Earth Maps(tm)
- DeLorme Mapping provides street-level maps and trip routing for any location in
the US, with a simple interface and faster response time than their competitors.
- Harvard Geospatial Library
- This interactive map is most useful for its ability to posion place names
from its 7-million-entry gazeteer, anywhere in the world. There are other
databases and multiple base maps to explore, too.
- Includes an interactive atlas and Java mapping applets.
- And they now do contourmaps!
- Microsoft Maps & Directions will generate a map for any place in the
U.S. given a street address.
- Topo maps and aerial photos by place, zip, or position.
- MassGIS serves
a variety of basemaps of Massachusetts with lots of interesting overlays.
- Iowa Geographic Image Map Server
- Orthophoto, shaded relief, topographic, and land cover maps for the
state of Iowa at the highest resolution available.
- Texas County Maps
- The University of Texas Department of Geography and its library
system are helping the Texas Department of
Transportation get their county maps online. They have a good start,
but a long ways to go. These maps have ALL roads labelled and serve as
a good example for other, smaller states to emulate.
Arizona State University Map links
- TIGER Map Service
- The goal of this service is to provide a public resource for generating
high-quality, detailed maps of anywhere in the United States, using public
- World of Maps
- Maps and travel guide books for destinations around the world in an
- U.S. National Park Service Digital Maps
- Detailed color maps of most sites of the National Park system in
JPEG, PDF, and Adobe Illustrator format.
- 1895 U.S. Atlas
- Very big JPEGs of the entire United States in 1895, county by county, state
by state, with railroads and most towns. It would be nice if more compressed
versions were available.
Astronaut Photography of the Earth
- Access to all photographs of the earth taken by American astronauts
since 1961 through a multi-level clickable map search.
Open source JavaBeans for viewing and manipulating geospatial information
from BBN Technology.
MIT/MassGIS Digital Orthophoto Project
- Graphical access to aerial photographs of the Boston area at varying
- Microsoft Terraserver
- Not maps but USGS or SOVINFORMSPUTNIK images of some of the earth,
searchable by place name or mouse.
- Keyhole: "The Ultimate Interface to the Planet"
- This program, for Windows only, interfaces over the web with a database
of aerial photographs. You can zoom from the whole planet Earth to street
level, and even deeper over some cities. Google bought the company in October
of 2004 and reduced the price of the consumer version to $29.95. There are
some interesting demos on their web site. Images are updated as new coverage
- Great Globe
- Hundreds of globe images and world maps.
- Harvard Map
- The Harvard Map Collection is one of the largest and oldest
collections of cartographic materials in the United States.
- Harvard Links tro Interactive Mapping Sites
- The Harvard Map Collection keeps up to date with this great list of
links to online interactive maps.
Maps of Specific Locations
- Mapping Boston
- A great collection of maps of Boston over 4 centuries, exhibited in
1999 at the Boston Public Library and the New England Acquarium and
collected in a book.
- Peacock Maps
- Great wall maps of the Internet from its inception to the present
GMT - The Generic Mapping Tools
- GMT is a free, open source collection of ~60 UNIX tools that allow
users to manipulate (x,y) and (x,y,z) data sets (including filtering,
trend fitting, gridding, projecting, etc.) and produce Encapsulated
PostScript File (EPS) illustrations ranging from simple x-y plots
through contour maps to artificially illuminated surfaces and 3-D
perspective views in black and white, gray tone, hachure patterns,
and 24-bit color. GMT supports 25 common map projections plus linear,
log, and power scaling, and comes with support data such as coastlines,
rivers, and political boundaries.
- MapServer is an OpenSource development environment for building
spatially enabled Internet applications. The software builds upon other
popular OpenSource or freeware systems like Shapelib, FreeType, Proj.4,
GDAL/OGR and others.
- GRASS GIS (Geographic Resources Analysis Support System) is an open
source Geographical Information System (GIS) with raster, topological
vector, image processing, and graphics production functionality that
operates on various platforms through a graphical user interface and
shell in X-Windows. It is released under GNU General Public License (GPL).
Documentation is available through the
- A TIFF based interchange format for georeferenced raster imagery.
- JPL Cartographic Applications Group
- The JPL Cartographic Applications Group is involved with many projects
involving digital cartography, Geographic Information Systems, Digital
Elevation Models, Terrain Analysis and Remote Sensing.
- U.S. Geological Survey
- The USGS covers many topics in geology, mapping, and water
resources. They have pointers to a lot of
- DeLorme Mapping
- Creators of Street Atlas and Eartha software.
produces online maps using the Street Atlas database.
- This program and its ancillary utilities are Microsoft Windows freeware.
They were written in C by Doug Cox, a retired airline pilot and download
aerial photo and topo map data from Microsoft's free TerraServer Web site,
save it on your hard drive, and create seamless maps from it.
