35.0 55.0 90.0 When this field is present, the

PATTERN_LINE_START and

PATTERN_LINE_REPEAT will be ignored.

INLINE_INIT_MASTER_SE ARCH_SIZE

Integer Pixels >0 100 This is the width and height of the initial search area around the seed point on the master image to locate an interest point. INLINE_TARG_TEMPLATE_

SIZE Integer Pixels >0 15 This is the size of the image template given in pixels. INLINE_L1_ELEV Double Proj

Dist Unit

1000 If the ELEV_MODE from above is set to MANUAL then this is the L1 rectification elevation used within the ADS APM to rectify the master and target patches.

INLINE_MIN_ELEV Double Proj Dist Unit

900 If the ELEV_MODE from above is set to MANUAL then this is minimum elevation used for the epipolar search.

INLINE_MAX_ELEV Double Proj Dist Unit

1100 If the ELEV_MODE from above is set to MANUAL then this is maximum elevation used for the epipolar search.

INLINE_RMS_CUTOFF_PE

R_PIXEL Double Unitless >0 1.5 Represents gray value differences between the master and target templates. INLINE_CORRELATION_CU

TOFF Double Unitless 0-1.0 0.7 Cross-correlation threshold for inline matches. INLINE_PARALLAX_CUTOF

F Double Pixels 0 4.0 Parallax threshold used for discarding points while finding points in the same strip. INLINE_EXPECTED_PARAL

LAX Integer Pixels >0 6 The a priori parallax error. This affects the search width and minification logic for the target area. Increasing this value will increase the number of pixels searched (at the price of speed). Increase this value (and the cutoff value) when large initial

parallaxes are observed.

TRANSFER_TEMPLATE_SIZ Integer Pixels >0 15 Size of the image template used for transfer

TRANSFER_PARALLAX_CU TOFF

Double Pixels >0 9.0 Parallax threshold used for discarding points during a transfer operation.

TRANSFER_INLINE Integer Boolean 0 or 1 0 This option is used when adding bands to a strip and transferring points to these new bands without having to re-run the point finding operation on the entire strip. Setting value to 1 will allow the existing points to be transferred to newly added band in the same strip.

SUBPIXEL_SEARCH Integer Boolean 0 or 1 1 Sets whether subpixel matching estimation will be used. Subpixel matching should improve the matching accuracy. This should be reflected in a smaller a-posteriori sigma0 in the AT. This function will increase

matching time.

RECTIFY_SUBBLOCK_SIZE Integer Pixels >0 4 The L1 subpatch to be rectified. A larger value will increase speed but possible decrease rectification accuracy (depending on flight dynamics). A smaller value will decrease speed but increase rectification accuracy.

ALLOC_MAXSIZE Integer Bytes >0 4000000 The largest allowable buffer memory allocation size to be created for reading image buffers.

INTEREST_WINDOW_SIZE Integer Pixels >0 11 Interest operator window size (value should be an odd number).

INTEREST_CIRCLE_CUTOF F

Double Unitless 0-1.0 0.75 Interest operator "roundness" cutoff for determine best interest point.

APM_MODE String FULL,

INLINE _ONLY, TRANS FER_O NLY

FULL This tells the APM operation to find and transfer points. Allows for transfer of points only, find new points within ADS Lines only, or perform both operations.

ELEV_MODE String DEM, MANUA L

DEM This elevation mode is used to select the method which APM will use to set the terrain height seed point for finding points. Valid entries are DEM or MANUAL. The DEM setting will force APM to use the DEM specified by the user in the XPro

initialization file or alternatively with the DEM_NAME. IPAS CO+ installation supplies a global JPTF DEM with grid spacing of 30 arc seconds (derived from USGS GTOPO30 dems). Accuracy varies by location but is typically better than 100m.( MANUAL will force the APM to use elevations defined within this settings file.

DEM_NAME String When the elevation mode is set to DEM, this value can identify the full path of the JPTF dem file. APM will use the default DEM specified in the XPro initialization file. DEM_ACCURACY Double Proj

Dist Unit

>0 50 This is a scalable value that allows you to set the perceived accuracy of the DEM. Since the JPTF DEM is roughly 1 km spacing, not all regions on the surface of the earth can be represented very well. For instance,

mountainous regions with many valleys and fast changing terrain will not be described very well with a coarse JPTF DEM. This value allows the APM to expand the search along the epi-polar line for points. A larger DEM_ACCURACY value will open a longer search space along the epi-polar line to search for points. A larger value will also generate more samples for the APM to test, thus slowing down the overall APM process. For flat terrain this value can be set lower, but for mountainous regions, this might be set higher to aid in finding more points. INLINE_MATCHMODE Integer Integer 1,4 1 This is the algorithm used to match points.

TRANSFER_MATCHMODE Integer 1,4 1 This is the algorithm used to match points. 1 = Conventional epi-polar constrained cross-correlation; 4 = Hierarchical search
