NOTE: requires gdalwarp and gdal_translate >1.5.1, specified by $DV_GDAL_PATH e.g. add putenv("DV_GDAL_PATH","/usr/bin/" to ~/.dvrc or library*.dvrc Arguments and Return Values Inputs: the index, processed data, ddr OR standard CRISM structure from process_crism() with the indexes created Outputs: a projected, colorized CRISM index image Usage Syntax: project_crism_index (index_image, data, ddr [,proj=STRING][,planet=BOOL][,index=INT][,colors=INT][,ignore=VAL][,stretch=STRING][,variance=VAL][,in_low=VAL][,in_high=VAL]) OR project_crism_index (struct=STRUCT [,proj=STRING][,planet=BOOL][,index=INT][,colors=INT][,ignore=VAL][,stretch=STRING][,variance=VAL][,in_low=VAL][,in_high=VAL]) REQUIRED: index_image - the index created by create_indices() ddr - the specific ddr lat/lon bands data - 1 or 3 band byte fully processed CRISM data OR struct - the complete structure from process_crism() OPTIONS: proj - projection type, "simp" or "sinu", default is "simp" planet - use the Mars ellipsoid reference (Default is 1) index - use if more than one index is supplied (Default is 1) e.g. index=5 is the 5th index in the index array in the z direction colors - color options from colorize() (Default is 5) ignore - ignore value of the image (Default is 0) stretch - type of stretch to perform on the data "sstretch" (default) or "lstretch" variance - variance setting for "sstretch" option (default is 40) in_low - low data value input for "lstretch" option (default is min data) in_high - high data value input for "lstretch" option (default is max data) Examples dv>out=process_crism("000035B5_07") struct, 1 elements long: struct, 7 elements anc: struct, 5 elements... wl_array: 1x1x438 array of double, bil format [3,504 bytes] at_array: 320x1x438 array of float, bil format [560,640 bytes] id: ""HRS000035B5_07_IF174L_TRR2.IMG"" data: 320x225x438 array of float, bsq format [126,144,000 bytes] index: 320x225x16 array of double, bsq format [9,216,000 bytes] index_key: Text Buffer with 16 lines of text 1: Olivine Index 2: LCP Index 3: HCP Index 4: Ferric Coating 5: BD2290 MG, Fe-OH Minerals 6: D2300 Hydrates Minerals - Particularily Phyllosilicates 7: BD2210 AL-OH Minerals 8: BD1900 H20 - Alternate from CAT code 9: SINDEX Water Containing Minerals 10: BD2100 Monohydrated Sulfates dv> LCP_proj_color=project_crism_index(struct=out,index=2) 0...10...20...30...40...50...60...70...80...90...100 - done. 0...10...20...30...40...50...60...70...80...90...100 - done. 0...10...20...30...40...50...60...70...80...90...100 - done. .01340x269x3 array of byte, bsq format [274,380 bytes] Images Left - un-projected CRISM index image, Right - projected colorized CRISM image
