(5) IPADS Map Maker window will be displayed with the available data blocks and map scales listed.
NOTE
The IPADS Map Maker window "look" and input data fields vary with the
type of coordinates selected for display, Figures 6-2 through 6-4.
UTM is the default coordinate type.
Changing the coordinate type will clear data input fields and checked data
blocks.
(6) Click on the UTM, Lat/Lon (D/M/S), or Lat/Lon (D.D) radio button to select the desired coordinate
type.
NOTE
A line containing a check box, map scale, coordinates of the southwest data
block corner, and the coordinates of the northeast data block corner will be
displayed for each data block available on the CD.
Map scales are displayed as given on the CD. Map scales are expressed as
ratios (e.g. 1:50K or 1:1M, where "K" means "thousand" and "M" means
"million".) While seeming counter-intuitive, the larger the number on the
right side of the colon (:) the smaller the map scale. e.g. 1:1M is smaller
than 1:50K.
The same map scale may be represented differently on the CD. e.g. 1:50K,
1:50k, and 1:50,000 are different representations of the same map scale.
IPADS Map Manager handles these different representations.
Larger scale maps have more detail than smaller scale maps. When there is
a choice, choose the larger scale (e.g. 1:50K rather than 1:250K.) Maps at
scales smaller than 1:250K generally are inadequate for IPADS navigation.
