DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION Data Set Overview : This data set contains images where multiple frames are mosaicked into a single RDR product. The methods for this process are applied by the Multimission Instrument Processing Lab (MIPL) under the Operational Product Generation Subsystem (OPGS), associating projections with the mosaicking process. It should be noted that governing methods and software can differ between OPGS and other operations subsystems or science instrument teams. For additional information about mosaic processing, including the purpose and content of ancillary files, consult the MSL_CAMERA_SIS.PDF in the DOCUMENT directory of this volume. Products : Below is a high level description of the types of mosaics produced to support MSL rover operations: - Cylindrical Projection: images are overlaid onto azimuth and elevation grid lines. In this case each pixel represents a fixed angle in azimuth and elevation. Rows are of constant elevation in the selected Mars coordinate frame. Optionally, individual frame boundries may be super-imposed and annotated by number. - Camera Point Perspective: a perspective projection from a synthetic camera, behaving as if the camera had a much larger field of view. Point-perspective mosaics give the most natural view of small areas, and are suitable for stereo viewing, but cannot be used for large fields of view. For MSL, this type of mosaic is typically computed in Rover Frame, and thus may have a tilted horizon if the rover was not level. - Cylindrical-Perspective Projection: used for large stereo panoramas, and work across a full 360 degrees of azimuth. Stereo is preserved because a baseline separation is maintained between the camera eyes at different azimuths. - Polar Projection: provide a quasi-overhead view that still allows viewing all the way to the horizon. Nadir is at the convergent center and the horizon is corrected for lander tilt. - Vertical Projection: provide a view of the surroundings as if you were looking straight down. They are useful for establishing environmental context or comparing with orbital imagery, but suffer from severe distortion with any variance of the scene from the surface model. In particular, rocks appear elongated, and terrain is not taken into account. - Orthographic Projection: this type of mosaic is a generalization of the vertical projection. It differs in that an arbitrary axis of projection (as well as X- and Y-axes in the plane of projection) can be specified. - Orthorectified Projection: used to show a 'true' view of the scene from a different point of view, without distortion due to parallax. The point of view is usually overhead, resulting in an image suitable for comparison with satellite imagery. The removal of parallax leads to gaps in the mosaic, which do not occur in other projections. - Non-image Mosaics: Normally mosaics are created using imagery, where each pixel is either a raw or radiometrically corrected intensity value. However, mosaics can be created using other types of pixels, e.g. XYZ, surface normal (UVW), range or slope. Any projection may be used, and all output values must be defined in the same coordinate system. Data : The mosaics are typically 1 or 3 banded 16-bit signed integer or floating point files - the actual format matches the format of the input data. Each mosaic has a dual ODL3/VICAR label attached to the binary file, accompanied by a detached PDS3 label. Software : The MIPL Mars Program Suite was used to generate these mosaics.
