H-9. IPADS Map File Preparation Continued
(2) File Size. IPADS map image files created by IPADS Map Manager will not exceed 64MB in size. If a
single IPADS map image file covering the map preparation area exceeds 64MB, IPADS Map Manager
automatically prepares multiple IPADS map files with overlapping boundaries as described in
(3) File Names. IPADS Map Manager automatically assigns map names using the map name convention
described in Appendix A of the IPADS Accessory Software Interface ICD. IPADS Map Manager
allows the operator to enter an optional map name prefix (up to eight characters in length) for the map
preparation area. Characters used in file names are limited to those specified in the IPADS Accessory
Software Interface ICD. Map image file names are the map name with a .bmp file extension. Map text
file names are the map name with a .txt file extension.
(4) Output File Location. IPADS map files, prepared by MM, are placed in the \IPADS Map Library\
folder on the installation drive of the host PC.
c.
Map Preparation Area. IPADS Map Manager provides the capability for the operator to specify the
boundaries of the map preparation area. Threshold Boundary coordinates are numerical. Objective
Boundary coordinates are graphical.
(1) Coverage Area. IPADS Map Manager allows entry of boundaries within 80 S to 80 N latitude and
180 W to 180 E longitude.
(2) Coordinate Types. IPADS Map Manager allows the operator to select boundary coordinate entry as
UTM grid coordinates, latitude and longitude in decimal degrees, and latitude and longitude in
degrees, minutes, and seconds.
(3) Coordinate Formats. Coordinate formats and hemisphere conventions will be consistent with those in
MIL-PRF-52955C.
(4) Coordinate Resolution. Coordinate entry resolution is to the nearest minute for latitude and longitude
in degrees, minutes, and seconds, and to the nearest 1,000 meters for UTM.
(5) Error Checking. IPADS Map Manager provides error messages, requiring operator acknowledgement,
when:
(a) Coordinates are outside the coverage area, H-9c(1)
(b) The UTM grid zone number is outside the range of 1 through 60.
(c) UTM coordinates are more than 45KM outside the normal grid zone boundaries. Normal grid
zone boundaries are three degrees in longitude from the central meridian, worldwide.
(d) Coordinates of the eastern boundary are equal to or west of those for the western boundary.
(e) Coordinates of the southern boundary are equal to or north of those for the northern boundary.
d. Processing.
(1) Enablement. Map preparation will not be enabled until:
(a) One or more source data blocks have been selected for processing, and coordinates for all four
boundaries have been entered.
(b) An input parameter has been changed and the conditions of H-9d(1)(a) have been satisfied after
processing has been completed.
(c) An input parameter has been changed and the conditions of H-9d(1)(a) have been satisfied after an
error has been deleted.
(2) Initiation. After map preparation is enabled, map preparation will be initiated by operator action.
(3) Duplicate Files. If the \IPADS Map Library\ folder already contains map files with the same name as
the files being created, IPADS Map Manager replaces the old files with the new ones without operator
intervention.
