There are two options for describing input images. Either: List the image file names Or: provide an ascii file with the file names listed, one per record. The input images can be 1-band or multi-band. The input images must be co-registered to the images provided in IN_XYZ parameter.
There are two options for describing IN_XYZ. Either: List the image file names Or: provide an ascii file with the file names listed, one per record. The input images must be 3-band in REAL (float) format. The bands are in x, y, z order. The input images must be co-registered to the images provided in INP parameter.
Output image contains the ORTHO mosaic.
Output image contains the DEM mosaic.
Corrected navigation filename. If marsnav was run on the input images it created a table of corrected pointing parameters. If you refer to this table using NAVTABLE it will override the pointing parameters (e.g. azimuth and elevation) in the picture labels, giving you a better registered mosaic.
Defines what value to be used for the no data areas in ORTHO output. The default value is 0.0. The value is going to be used as a flag to distinguish whether a position has a valid data or not, so the value of IMG_NODATA is better be set outside the image range.
Defines what value to be used for the no data areas in DEM output. The default value is the maximum floating point number, which is 3.40282E+38. The value is going to be used as a flag to distinguish whether a position has a valid value or not, so the value of DEM_NODATA is better be set outside the image range.
Defines the size in pixel for fill implementation.
Defines the method for fill implementation. UNIFORM mode will fill all the boxes with a uniformed size defined by FILL_SIZE. WEIGHTED mode will use the distance between a pixel to camera as the weight. The pixel that is closest to camera will be assigned fill size 1, and the pixel that is furthest away from the camera will be assigned fill size defined by FILL_SIZE. The fill sizes of pixels in between will be linearly mapped.
Override FILL_SIZE for DEM output.
Specifying a range will override the automatically determined min/max x/y, so for example saying range=50 will set the output to +/- 50 meters in both directions. This can be overridden by the specific MIN/MAX X/Y parameters. If RANGE is given and CUT is not, the default for CUT is to cut a circle at the same size of RANGE.
Specifies the size of the circle/sawtooth shape (see CUT_TYPE) at which to cut the data, as a 2D distance from the coordinate system origin or a 3D distance from camera. If the value is 0, no cut is performed (i.e. the output goes to the corners of the rectangle). If the value is undefined, the value of RANGE is used. Thus specifying RANGE=50 will set the size of the image to +/-50 meters and do a circular cut at 50m distance. RANGE=50 CUT=40 will set the image to 50 meters in size but cut all data at 40m (thus leaving missing data around the circle). RANGE=50 CUT=0 will set the image to 50 meter range but not cut in a circle. CUT=50 will not set the size of the image (it comes instead from the auto min/max x/y, parameters, or NL), but it will cut a circle at 50m.
CIRCLE = 2d distance from coordinate system origin, results in circular image. SAWTOOTH = 3d distance from camera (each camera), results in sawtooth pattern for typical mast-mounted camera panoramas since the camera origin changes with each image.
The BSQ input file band number. Defaults to undefined. The parameter defines which band(s) in skin images will be processed to put in ORTHO output mosaic. If BAND=N, then only that band in skin images will be processed. If BAND is left to be undefined, then all bands in skin images will be processed.
Specifies the minimum extent of the image in meters in the X direction. If MINX is undefined, the program computes the minimum x value from the XYZ data provided with IN_XYZ parameter. If parameter RANGE is provided, then MINX is overriden by -RANGE.
Specifies the maximum extent of the image in meters in the X direction. If MAXX is undefined, the program computes the maximum x value from the XYZ data provided with IN_XYZ parameter. If parameter RANGE is provided, then MAXX is overriden by RANGE.
Specifies the minimum extent of the image in meters in Y direction. If MINY is undefined, the program computes the minimum y value from the XYZ data provided with IN_XYZ parameter. If parameter RANGE is provided, then MINY is overriden by -RANGE.
Specifies the maximum extent of the image in meters in Y direction. If MAXY is undefined, the program computes the maximum y value from the XYZ data provided with IN_XYZ parameter. If parameter RANGE is provided, then MAXY is overriden by RANGE.
The scale for both DEM and ORTHO output mosaic, it is measured in meters per pixel. If it is defined, the mosaic will be set exactly at that resolution. If it is undefined, then SCALE will be computed based on NL, MINX, MAXX. Either SCALE or NL needs to be provided for the program to compute output's geometry.
Keyword parameter that provides 6 different methods of handling overlay areas
in DEM and ortho output mosaic. It defaults to method FIRST.
1. CLOSEST = closest to camera.
When multiple points hit the same position, the one that is the closest to
the camera will be picked and written in the output mosaic. This method
should give the best result if input XYZ data contains lesser noise.
2. AVG = average.
When multiple points hit the same position, the average value of the points
will be picked and written in the output mosaic.
3. MIN = minimum.
When multiple points hit the same position, the minimum value of the points
will be picked and written in output mosaic.
4. MAX = maximum.
When multiple points hit the same position, the maximum value of the points
will be picked and written in output mosaic.
5. FIRST = first on top.
If this mode is enabled, depending on the images order in the input list,
the points from images on top of the input list will have higher priorities
to be picked and written in the output mosaic. For example, given the
input list to be in the order of img1, img2, and img3, points come from img1
will be picked when there are overlap areas between img1 and img2; points
come from img2 will be picked when there are overlap areas between img2 and
img3.
6. LAST = bottom on top.
If this mode is enabled, depending on the images order in the input list,
the points from images on bottom of the input list will have higher
priorities to be picked and written in the output mosaic. For example, given
the input list to be in the order of img1, img2, and img3, points come from
img2 will be picked when there are overlap areas between img1 and img2;
points come from img3 will be picked when there are overlap areas between
img2 and img3.
Keyword parameter that turns on or off radiometric correction of the input images. RAD (the default) enables the correction (for missions/instruments which support it), while NORAD disables it. For input images which are in REAL(float) format, radiometric correction is disabled.
Specifies an input file containing brightness corrections. This is an XML file that comes from a program like marsbrt which contains correction factors for each image. These factors may be additive or multiplicative constants to be applied to the image, or other corrections that may be implemented in the future.
The range of inputs to actually mosaic. Normally all inputs are mosaicked. However, if this parameter is specified, all inputs will be used to calculate the output projection, but only the inputs in the specified range will be mosaicked. The input numbers are 1-based. If only one number is specified, it is the starting number; the end defaults to the # of inputs.
Flag to enable erosion feature. If it is on, then the program will erode the borders of generated DEM and ORTHO results. Note that the erosion will feature will erode all the holes in DEM and ORTHO results.
Structuring element shape for erosion feature. Currently, two default shapes SQUARE and DIAMOND are provided. Using different structuring element shape will cause the program to erode borders and holes differently.
Defines how much to erode borders and holes. If it is on QUARTER mode, then 1/4 of the fill will be removed. If it is on HALF mode, then 1/2 of the fill will be removed. If it is on FULL mode, then the entire fill will be removed.
Number of Lines for both DEM and ORTHO output mosaic. If it is defined, the number of lines of the mosaic will be set exactly to that number. If it is undefined, it is computed based on SCALE, MINX, and MAXX. Either NL or SCALE needs to provided for the program to compute output's geometry.
A colon-separated list of directories in which to look for configuration and calibration files. Environment variables are allowed in the list (and may themselves contain colon-separated lists). The directories are searched in order for each config/cal file when it is loaded. This allows multiple projects to be supported simultaneously, and allows the user to override any given config/cal file. Note that the directory structure below the directories specified in this path must match what the project expects. For example, Mars 98 expects flat fields to be in a subdirectory named "flat_fields" while Mars Pathfinder expects them to be directly in the directory specified by the path (i.e. no intermediate subdirectories).
Specifies a mission-specific pointing method to use. Normally this parameter is not used, in which case the "default" pointing methods are used. Some missions may have special, or alternate, pointing methods available, which are indicated by this string (for example, backlash models, using arm joint angles instead of x/y/z/az/el, etc). A substring search is used, so multiple methods (where that makes sense) can be specified by separating the keywords with commas. Note that nav files created using one pointing method will most likely not be compatible with a mosaic created using a different pointing method. The methods available vary per mission, but some methods available at the time of this writing are:
Disables all label-derived parameters to the Site mechanism which underlies coordinate systems. This forces all sites to be identical, with all rotations and offsets set the same. In the case of MPF or Mars 98, this disables the lander quaternion and offset (sets them to identity and 0, respectively). This option should not be used with images taken from different vantage points (e.g. the spacecraft moved, or mixing a lander and a rover) or invalid results will be obtained. The use of this option invalidates the Fixed coordinate frame; any values reported in the Fixed frame will not correctly reflect the orientation of the lander/rover. Obviously, this option should be rarely used; it is intended for when the image labels defining the site are invalid or inconsistent.
The DATA_SET_NAME typically identifies the instrument that acquired the data, the target of that instrument, and the processing level of the data. This value is copied to the output label, property IDENTIFICATION, keyword DATA_SET_NAME.
The DATA_SET_ID value for a given data set or product is constructed according to flight project naming conventions. In most cases the DATA_SET_ID is an abbreviation of the DATA_SET_NAME. This value is copied to the output label, property IDENTIFICATION, keyword DATA_SET_ID.
When a data set is released incrementally, such as every three months during a mission, the RELEASE_ID is updated each time part of the data set is released. For each mission(or host id if multiple spacecrafts), the first release of a data set should have a value of "0001". This value is copied to the output label, property IDENTIFICATION, keyword RELEASE_ID.
Specifies a permanent, unique identifier assigned to a data product by its producer. Most commonly, it is the filename minus the extension. This value is copied to the output label, property IDENTIFICATION, keyword PRODUCT_ID.
Specifies the unique identifier of an entity associated with the production of a data set. This value is copied to the output label, property IDENTIFICATION, keyword PRODUCER_ID.
Specifies the identity of a university, research center, NASA center or other institution associated with the production of a data set. This value is copied to the output label, property IDENTIFICATION, keyword PRODUCER_INSTITUTION_NAME.
Specifies a target. The target may be a planet, satelite, ring, region, feature, asteroid or comet. This value is copied to the output label, property IDENTIFICATION, keyword TARGET_NAME.
Specifies the type of a named target. This value is copied to the output label, property IDENTIFICATION, keyword TARGET_NAME.
Rover State File. This is a list of filenames to load containing Rover State information. These files contain position and orientation information for a rover (or other mobile spacecraft) at various sites. They are in XML format. See the "Rover Motion Counter (RMC) Master File SIS" for details on these files. Rover State Files have a priority order. The files listed first have the highest priority. Environment variables may be used in the list. For MER, if a directory is specified, then that directory is searched for RMC Master files and any found are loaded. The directory structure and filename convention is covered in the RMC SIS. The directory specified is the one containing "master", so if <dir> is the name specified in the RSF parameter, the following files will be searched for: <dir>/master/_Master.svf <dir>/master/ _Site_ _Master.rvf The name of each file loaded is printed to the stdout log for reference.
If enabled, this causes the internal database of RMC locations to be printed out to the stdout log. This is after the RSF files have been loaded and the coordinate systems read from the input label(s).
The coordinate system to use for all input parameters and output values,
and the mosaic itself. The interpretation of the values is dependent on
the mission. Some representative missions are listed here:
Fixed - The Fixed frame. This is the ultimate reference frame
(see also FIXED_SITE for rover missions).
Instrument - (default) The "natural" frame for the instrument
(of the first input image). MPF: Lander or Rover; M98: MVACS; MER: Rover.
Site - A major Site frame. For rover missions, COORD_INDEX specifies which
Site frame to use. Non-rover missions treat this as Fixed.
Rover - An instance of the Rover frame. For rover missions, COORD_INDEX
specifies which instance of the rover frame to use. Non-rover mission
use the spacecraft frame (e.g. Lander for M98). For MSL, this is the
Rover Nav frame.
Local_Level - An instance of a Local Level frame. This is typically
coincident with the Rover frame (in XYZ) but oriented toward North
like the Site and Fixed frames. For MER, this is an instance of a
Drive index move.
RMECH - for MSL, this is the Rover Mechanical frame. It should not normally
be used except for testing.
The index specifies which instance of a coordinate system to use. It is currently applicable only to rover-based missions, but could have other uses. The index is equivalent to the Rover Motion Counter (RMC) for MER and FIDO. For MER/FIDO, there are many Site frames. Each is numbered with a single index. For Site Frames, coord_index specifies which to use. Likewise, there are many Local_Level and Rover frames, corresponding to values of the RMC. The multiple instances of this frame are selected by COORD_INDEX. Generally COORD_INDEX defaults sensibly so you don't usually need to specify it. It will default to the instance used by the first input.
Specifies which major Site is the "Fixed" Site for this run.
Historically, MPF and M98 had a single "Surface Fixed" frame which never
moved, and which all other coordinate system frames were referenced to.
With the advent of long-range rovers (such as MER and FIDO), that became
insufficient. The rover traverses far enough that errors in knowledge of
coordinate system offset and orientation become unacceptable.
For this reason, a system of major Sites was introduced. Periodically
during the mission, a Site frame is declared. This then becomes the
reference frame for all activities until the next Site is declared.
References are kept local, and errors don't propogate across Sites.
However, if images from more than one Site are combined together, the
Site's must be placed relative to each other. Therefore a single reference
frame is still needed to combine different sites.
The FIXED_SITE parameter controls which of the major Site frames is
the reference ("fixed") site for this program run. This fixed frame
can vary in different program runs, but is constant throughout one
execution.
If not specified, FIXED_SITE defaults to the minimum Site number (i.e.
lowest numbered, or earliest chronologically) used in all input images.
Normally this default is sufficient; rarely must FIXED_SITE be specified.
One or more Rover State Files must usually be specified in order to combine
image from more than one Site. These describe the relationship between
sites. See the RSF parameter.
Specifies which solution ID to use when specifying the coordinate system. There are potentially many different definitions for the same coordinate system. These are identified via a unique Solution ID. If this parameter is given, only the specified solution's definition is searched for. Without it, the "best" available solution is chosen. It is extremely rare that this parameter should be needed. The default will be sufficient in almost every case. Note that the current MER implementation requires that a value for COORD_INDEX also be provided, in order for this parameter to take effect.
