Parameter descriptions

FILE

Specifies the name of the PCIDSK file to receive the georeference segment containing the projection parameters.

DBGEO

Specifies the georeference segment to receive the projection data. If this parameter is not specified, a new segment is created.

Note: Because MAKEPRO2 is used to define a projection (but no image bounds), it is recommended that you create a new segment, or use an existing georeference segment other than segment 1.

PROJECT

Specifies the projection.

Other supported units include:

ZONE

Specifies the projection zone, for UTM or State Plane projections.

If the projection is:

If the projection is not UTM or State Plane, this parameter is not used.

Note: If ZONE is defined, its value takes precedence over any zone defined in the PROJECT parameter.

ROW

Specifies the projection zone rows, for UTM or UPS projections.

If the projection is:

If the projection is not UTM or or UPS, this parameter is not used.

Note: If ROW is defined, its value takes precedence over any ROW defined in the PROJECT parameter.

ELLIPS

Specifies the model to use to define the shape of the earth.

ELLIPS can be set directly with an ellipsoid code or a datum code. For example any of the following can be used for WGS84:
Note: If ELLIPS is defined, its value takes precedence over any ellipsoid defined in the PROJECT parameter.
If the ellipsoid is not supported one of the supported earth models, it may be defined explicitly, in meters, as follows:

EXTRAINF

Optionally specifies whether to prompt for the information that defines the projection.

Supported values are:
Note: When this parameter is set to "DEFAULT", for projections where the parameters cannot be specified using the PROJECT, ZONE, ROW, and ELLIPS parameters, MAKEPRO2 will exit.

PROLONG

Specifies the reference longitude for the projection:

("-180" (or "180W") to "+180" (or "180E"))

PROLAT

Specifies the reference latitude for the projection:

("-90" (or "90S") to "+90" (or "90N"))

STPAR1

Specifies the first standard parallel for conic projections:

("-90" (or "90S") to "+90" (or "90N"))

This parameter may be used for the following conic projections:

STPAR2

Specifies the second standard parallel for conic projections:

("-90" (or "90S") to "+90" (or "90N"))

This parameter may be used for the following conic projections:

EFALSE

Specifies a false easting for the projection coordinates.

NFALSE

Specifies a false northing for the projection coordinates.

SCALE

Specifies the scale factor to be used for the projection.

This parameter may be used for the following projections:

PHEIGHT

For the General Vertical Near-Side Perspective projection (GVNP), this parameter specifies the height of the perspective point above the surface of the earth as a sphere.

LONG1

For the Oblique Mercator projection, Format A (OM), this parameter specifies the longitude of the first point defining the central line for the projection ("-180" (or "180W") to "+180" (or "180E")).

LAT1

For the Oblique Mercator projection, Format A (OM), this parameter specifies the latitude of the first point defining the central line for the projection ("-90" (or "90S") to "+90" (or "90N")).

LONG2

For the Oblique Mercator projection, Format A (OM), this parameter specifies the longitude of the second point defining the central line for the projection ("-180" (or "180W") to "+180" (or "180E")).

LAT2

For the Oblique Mercator projection, Format A (OM), this parameter specifies the latitude of the second point defining the central line for the projection ("-90" (or "90S") to "+90" (or "90N")).

AZIMUTH

Specifies, in degrees, the azimuth East of North for the central line for the projection ("0.0" to "360.0").

AZIMUTH may be used for the following projections:
Note: This parameter may be entered as an integer or as decimal degrees, NOT as degrees, minutes, seconds.

LSATNUM

For the Space Oblique Mercator projection (SOM), this parameter specifies the number of the Landsat satellite. This value is required to properly access the defined PATHNUM, as the Landsat 4 and 5 have a different orbit than Landsat 1, 2, and 3.

PATHNUM

For the Space Oblique Mercator projection (SOM), this parameter specifies the Landsat path number.

REPORT

Specifies where to direct the generated report.

Available options are:

MONITOR

The program progress can be monitored by printing the percentage of processing completed. A system parameter, MONITOR, controls this activity.

Available options are:

Details

MAKEPRO2 stores projection information on a new or existing georeference segment in the specified output file. Because there are no input bounds for the image, it is recommended that you create a new segment, or use an existing georeference segment other than segment 1 (the Master Georeference segment for the file). To set projection parameters and bounds for the image, use SETPRO.

Information required for the projection is input to MAKEPRO2 as defined by the EXTRAINF parameter. If EXTRAINF="DEFAULT", the projection parameters are defaulted using the image bounds (ULX, ULY, LRX, LRY). If EXTRAINF="ASK", the projection parameters are input from the terminal. If EXTRAINF="EXPLICIT", the projection information must be explicitly input to the function using the required parameters, with no prompting or defaults.

Example

Define projection parameters (but no image bounds) for the file "irvine.pix".

EASI>file	=	'irvine.pix'	! file from which to project
EASI>dbgeo	=		! append a new georeference segment
EASI>project	=	'utm'	! Universal Transverse Mercator (UTM)
EASI>zone	=	11	! UTM zone 11
EASI>row	=	's'	! UTM row S
EASI>ellips	=	'd-1'	! "D-01", (NAD27 (USA, NADCON))
EASI>extrainf	=		! Default, "DEF"
EASI>prolong	=
EASI>prolat	=
EASI>stpar1	=	
EASI>stpar2	=
EASI>efalse	=
EASI>nfalse	=
EASI>scale	=
EASI>pheight	=
EASI>long1	=
EASI>lat1	=
EASI>long2	=
EASI>lat2	=
EASI>azimuth	=
EASI>lsatnum	=
EASI>pathnum	=

EASI>RUN makepro2

Running PROREP on the new georeference segment recorded in the LASC parameter will produce the following report on the terminal.

 irvine.pix                              [S   14PIC     512P     512L]
