Maps of unlimited size can be created. The standard BigTopo seamer can only
build maps 32,765 pixels on a side, limiting 1:24,000 maps to 77 miles
of height and width. BigTopoPro has no image size limits for maps saved as
bitmaps or .IT3 files. (It may not be possible to view images with the AllTopo
viewer larger than 1/4 gigabyte on Win95/98/ME systems.
1:24,000
scale, 1:50,000, 1:63,360, 1:100,000 scale and 1:250,000 scale maps can be seamed.
BigTopoPro will seam maps that cover adjacent 3 UTM zones to a single
map.
You can force a map generated with BigTopoPro to adjacent zones. For example
Crystal Bay of Lake Tahoe CA can be built as a UTM Zone 10 projected map (it's
natural UTM Zone):
Zone 10
or a Zone 11 projected map (the UTM Zone to
the right):
Zone 11
The text font, size, style and color may be selected for UTM, Lat/Lon
grids, titles and scales.
BigTopo Pro can
create maps in Nad27 or Nad83, for use in All Topo Maps or for export.
BigTopoPro maps can include a scale bar, magnetic declination is computed (for
the current year) and plotted:
BigTopo Pro can size a map to exactly fill a printer's page. Coverage may be
specified to include all points within an AllTopo HWP file plus a user
definable border.
Map coverage is now easier to define, parameters can be locked and
anchored.
BigTopo
Pro can exports high resolution images for the following formats: .bmp, .eps,
.gif, .pcx, .png, .tif, .jpg.
