Description of variables in g_map.tbl: (Text is provided
by Dr. Mark Stoelinga of University of Washington.)
|
LL
|
lat/lon lines over land only (L), water only (W),
none (N), or both land and water (D, A, or E)
|
|
DASH
|
lat/lon lines are dashed large (L), medium (M), small
(SM), tiny (T), solid (SO), publ. style (P), or default (D) [LL.ne.N]
|
|
INT
|
lat/lon grid interval in degrees, or D for default
[LL.ne.N]
|
|
LB
|
M for only MAPDRV labels (lat/lon on perimeter),
N for none,
or D or A for both
|
|
LSZ
|
lat/lon label size, 1 to 25 [LB.ne.N]
|
|
LQL
|
label quality: [LB.ne.N]
00 - Complex characters / High quality
01 - Complex characters / Medium quality
02 - Complex characters / Low quality
10 - Duplex characters / High quality
11 - Duplex characters / Medium quality
12 - Duplex characters / Low quality
D - Default = 11
|
|
P
|
draw just a line perimeter (N) or a line perimeter
with ticks (Y)
[DASH.ne.P.or.LL.eq.N]
|
|
TTL
|
title flag: read the next two title parameters (Y)
or skip to outline parameter (N)
|
|
TSZ and TQL
|
the same as LSZ and LQL except they refer to the
title [both TTL.eq.Y]
|
|
OUT
|
determines which geo-political outlines will be drawn:
NO - no outlines
CO - continental outlines only
US - U.S. State outlines only
PS - Continental + International + State outlines
PO - Continental + International outlines
|
|
DOT
|
determines whether geo-political boundaries will
be dotted (Y) or solid (N) [OUT.ne.NO]
|
|
LW
|
gives the line width, in multiples of default (which
is 1000 "units"). D gives default line width. [OUT.ne.NO.and.DOT.eq.N]
(LW=2 would double the line width for geographic
boundaries)
|
|
SP
|
gives dot spacing. Default (D) is 12 [OUT.ne.NO.and.DOT.eq.Y]
|
With each parameter is given a conditional statement. If that conditional statement is not met, then that particular box should be made blank. The most common error that occurs when the routine attempts to read this table is "Too many entries on line", which simply means that the routine expected a box to be blank, but it wasn't.
One can also do color filled maps. To do so, add the following in the g_map.tbl:
MAP FILL WATER | SIX COLOR INDICES WITH WHICH TO COLOR IN THE MAP ------------------------------------------------------------------------ 1 | 2 | 2 | 2 | 2 | 2 | 2 ------------------------------------------------------------------------In this example, the water will be colored white, and land light grey according to the color table.
