input file names (can be byte,halfword). The order in which the input data sets are specified determines the order of preference of the data at any pixel, i.,e., the data in INP(1) has precedence over all other data
output file name (can be byte, halfword)
the standard VICAR size field (only NL and NS are used and refer to the output picture size.) In the adaptive mode NL and NS refer to the maximum size of the output picture
Starting line of the size field--ignored
Starting sample of the size field--ignored
Number of lines in the size field or maximum size of the output picture.
Number of samples in the size field or maximum size of the output picture.
PIXL=(line1,samp1,line2,samp2,....,lineN,sampN) where (lineI,sampI) are the location in integer line and sample in the Ith input picture of a point common to all the pictures. (See LCP, SCP, which give the corresponding location in the output picture.)
lcp=line LCP is a keyword followed by an integer specifying the line position in the output picture of the common point referred to by the PIXL param
scp=samp SCP is a keyword followed by an integer specifying the sample position in the output picture of the common point referred to by the PIXL param
thre=n1 the integer N1 is the lower threshold DN value used in finding the edge of the input picture. (the default is 1) a valid picture edge is not found until NSEQ=N4 consequtive pixels of DN greater than THRE=N1 have been found.
lthr=n2 control the left/right threshold DN values individually. The program searches the picture inward from each edge to find a specified number of consecutive pixels above a certain threshold DN. The nominal threshold is specified by the keyword THRESH. If either of the keywords LTHRESH/RTHRESH is specified, it overrides the nominal value only for the left/right edge of the picture.
rthr=n3 control the left/right threshold DN values individually. The program searches the picture inward from each edge to find a specified number of consecutive pixels above a certain threshold DN. The nominal threshold is specified by the keyword THRESH. If either of the keywords LTHRESH/RTHRESH is specified, it overrides the nominal value only for the left/right edge of the picture.
ethr=n3 sets both the left and right thresholds. ETHRESH can be used when the edge detection thresholds are to be different from the picture threshold THRESH=N1.
nseq=n4 the integer N4 is the number of consecutive picture elements which must be greater than or equal to the lower threshold DN for a valid picture edge to be found.
lseq=n5 the parameters LSEQ/RSEQ allow the user to control the left/right threshold triggers individually. The program searches each input picture inward from the left/right edge until it finds LSEQ/RSEQ consecutive pixels which are greater than the threshold DN LTHR/RTHR. The nominal search values are specified by the parameter NSEQ. If either of the keywords LSEQ/RSEQ is specified, then it overrides the nomial (NSEQ) search value only for the left/right edge of the picture.
rseq=n6 the parameters LSEQ/RSEQ allow the user to control the left/right threshold triggers individuallt. The program searches each input picture inward from the left/right edge until it finds LSEQ/RSEQ consecutive pixels which are greater than the threshold DN LTHR/RTHR. The nominal search values are specified by the parameter NSEQ. If either of the keywords LSEQ/RSEQ is specified, then it overrides the nomial (NSEQ) search value only for the left/right edge of the picture.
ADAPT is a keyword which specifies that the input pictures have been map projected by MAP2 and that NEWMOS should attempt to just fit all the input pictures into the output picture. The ADAPT keyword is similar to the MAP2 keyword and implies the MAP2 keyword. The difference between the ADAPT and MAP2 keywords is that when ADAPT is specified, NEWMOS will determine the LCP and SCP parameters and change the size of the output picture to whatever size is necessary to fit all input pictures. This size will not be greater than the size specified in the VICAR size field. The default is to specify LCP, and SCP and create an output picture of the size specified in the VICAR size field. If the output picture should be bigger than NL * NS to contain all the input pictures the number of lines and samples will be truncated. For Mercator, normal cylindrical, and simple cylindrical projections, the number of samples for the output image is determined by one of two ways. By default, the program searches for the largest gap between the input images in the longitude direction. It then uses the ends of the gap as the left and right edges of the output image. Thus the output image contains all longitudes except for those in the largest gap. This is done to minimize the size of the output image. If there is no gap, the number of samples is set to correspond to 360 degrees of longitude. However, if the NOMIN keyword is specified, no attempt to minimize the number of samples is made, and it is possible to have more than 360 degrees of longitude in the output image.
If the NOMIN keyword is specified, no attempt to minimize the number of samples is made, and it is possible to have more than 360 degrees of longitude in the output image. This applies to both adaptive algorithm (see HELP ADAPT) and to the Normal Cylindrical case. For other map projections, the range of longitudes can exceed 0-360 degrees by adjusting the SAMPLE value of the MAP labels, but for Normal Cyl., this does not suffice: NOMIN must also be specified.
nibb=n7 The integer N7 specifies the number of pixels in from the edge of the picture to be set to a DCLEVEL. This parameter is designed to remove the interpolation at picture edges caused when LGEOM interpolates across a step function. (The default=0)
lnib=n8 The integers N8/N9 specify the number of pixels to be set to zero or to DCLEVEL at the left/right edge of the picture. These para- meters override the parameter NIBB. (The default is N8=N9=N7)
rnib=n9 The integers N8/N9 specify the number of pixels to be set to zero or to DCLEVEL at the left/right edge of the picture. These para- meters override the parameter NIBB. (The default is N8=N9=N7)
dcle=n10 The integer N10 specifies the background DN level N10 of all the pixels in the output picture which are not overlaid by input picture data. (The default=0)
incr=n11 The integer N11 specifies the frequency of sampling pixels in each line of each input picture to test for an edge. (The default is to sample every tenth pixel.) This option was put in to speed up the program.
FORMAT is a keyword which specifies the data type of the output files (HALF or BYTE). Default is that the output file has the same format as the input files.
AVER is a keyword specifying that the output mosaic should use the average of the DN's of pixels which have DN's greater then THRESH. Weighting is performed according to the weight keyword. DNout=sum(DNin*WEIGHTin)/sum(WEIGHTin).
Invokes the smooth option. In this mode the first half of the images are mosaicked using the second half of the images as weighting masks. See program MASKMOS to create the masks for you. DN_out= sum( DN_in * DN_mask *Weight_in) / sum( DN_mask * Weight_in)
Specifies the weighting of input images in the mosaic. Only used in the AVER and SMOOTH options. Specify only one weight per input image. In the SMOOTH option weights need only be provided for the first 1/2 of the images. Defaults to 1.0 for each input. For usage see the AVER and SMOOTH keywords. Example: weight=(1.0,2.0,1.2)
MAP2 is a keyword specifying that all the inputs have VICAR labels which contain all the information necessary to define the cartography of the input pictures. If this keyword is specified the user should not have done any other geometric transformation on the pictures after the MAP2 projection (including size field operations). The output label will be updated. (See also the ADAPT parameter.) If MAP2 is specified but ADAPT is not specified, then LCP and SCP should be specified but PIXL should not be specified. (For normal and simple cylindrical projections, LCP and SCP correspond to LAT=0 and LONG=0.) The default is to specify all the offsets for all the input pictures.
radi=r1 RADIUS is a keyword and R1 is a floating point number specifying the radius (in km.) of the planet being mosaicked. This is necessary only when the MAP2 keyword is specified and the frames are Mercator projected.
req=r2 REQ and RPOL are keywords similar to RADIUS but refer to the Equatorial and Polar Radius.
rpol=r2 REQ and RPOL arre keywords similar to RADIUS but refer to the Equatorial and Polar Radius.
Specifies the target body and thereby the radii used by the program.
