Sample map details:
The following maps were exported from Versamap 3 as Windows Bitmaps
(BMP) and as Windows Metafiles (WMF). To reduce file size, each
BMP image was converted to portable network graphics (PNG) format with
Microsoft Paint. WMF images are vector graphics files and can be
enlarged and reduced without loss of detail, whereas BMP and PNG images
are bitmapped files and do not enlarge or reduce well.
Sample world maps:
The following world map (WMF,
981 KB) was drawn on an Equirectangular projection, using
Vmap1.map (220,000 points), the most detailed digital map in the
Versamap Micro World Database. The map shows all geographic
features present in the database.
The following world map (WMF,
3325 KB), which emphasizes oceans and continental margins, was
drawn on an interrupted Mollweide equal-area projection. The map
shows the locations of all earthquakes of magnitude ≥ 5, that were
recorded between 1990 and 2007. The close correlation between the
epicenters (blue crosses) of oceanic earthquakes and the location (red
lines) of mid-ocean ridges, trenches, and transform faults is evident.
The world map in the following photograph was exported from Versamap
as an AutoCAD vector graphics .DXF file. A CAD/CAM program was
used to stretch the Versamap .DXF file, and to plot it for application
to the fuselage of the aircraft.
Sample maps showing Great and
Small Circles:
The following map (WMF,
536 KB),
on an Azimuthal equal-area projection, shows the epicenters of the
earthquakes that caused the tsunami of April 1, 1946 at Hilo, Hawaii
(blue); and the Indian Ocean Tsunami of December 26, 2004 (red).
Three small circles, at intervals of 1,000 nautical miles are drawn
around each epicenter.
The following map (WMF,
549 KB),
on an Equirectangular projection, show a series of great circles
centered on Moscow.
The following map (WMF, 559 KB)
shows the same great circles plotted on an Azimuthal equal-area
projection.
Sample maps of the Western
Hemisphere:
The following maps of the Western Hemisphere, on an Orthographic
projection, illustrate the geographic features and amount of detail
present in the Versamap Micro World Database and in World Data Bank
II. The maps show all geographic features in each database.
Versamap Micro World Database: Western hemisphere (WMF, 475 KB).
Versamap World Data Bank II: Western hemisphere (WMF, 10346 KB).
Sample maps of Cape Hatteras:
The following maps of Cape Hatteras are drawn on an Equirectangular
projection, and cover exactly the same area. Each map illustrates
the geographic features and amount of detail present in 1 of the 3
digital map databases available for use with Versamap.
The maps drawn with the Versamap Micro World Database, and Versamap
World Data Bank II show all geographic features present in these
databases. The map drawn with the Versamap USGS Digital Line
Graphs shows only a portion of the geographic features present in the
database.
Versamap Micro World Database: Cape Hatteras (WMF, 20 KB) showing all geographic
features in the database.
Versamap World Data Bank II: Cape Hatteras (WMF, 173 KB) showing all geographic
features in the database.
Versamap USGS Digital Line Graphs: Cape Hatteras (WMF, 1142 KB) showing the
coastline; islands; perennial rivers and lakes; and state and county
boundaries. Most geographic features, such as roads; railroads;
canals; national parks; and intermittent rivers and lakes are not shown.
Sample maps of the United States:
The following map (WMF, 6098 KB)
of the United States was drawn on an Albers equal-area conic
projection, using the USGS Digital Line Graphs digital map
database. The map shows the coastline; islands; lakes; and state
and county boundaries. Most geographic features, such as roads;
railroads; canals; national parks; rivers; and intermittent rivers and
lakes are not shown.
The following map (WMF, 804 KB)
of the Southwestern United States was drawn on a Cylindrical equal-area
projection, using the USGS Digital Line Graphs digital map
database. The map shows the coastline; islands; perennial rivers
and lakes; and state boundaries. Most geographic features, such
as roads; railroads; canals; national parks; intermittent rivers and
lakes; and county boundaries are not shown.
Sample maps of Japan and Korea:
The following map (WMF, 45 KB),
plotted from the Versamap Micro World Database on a Hammer equal-area
projection, shows Japan and Korea. The map shows all geographic
features present in the database.
The following map (WMF, 317 KB),
plotted from World Data Bank II on a Hammer equal-area projection,
shows Japan and Korea. The map shows all geographic features
present in the database.
