title: Data for "Wavelet Analysis of Concentric Crater Fill Surface Ridges"

description: This repository contains data associated with the paper: Cook, C. W., Byrne, S., 2025. Wavelet Analysis of Concentric Crater Fill Surface Ridges. Icarus (accepted).The folder Input_Data contains the following subfolders:CCF_HiRISE_profiles, which includes subfolders for image, orthoimage, DTM, and hillshade profiles. These in turn contain subfolders such as the following (not all subfolders included for each):shapefiles: shapefiles for profiles, including the drawn profiles (filenames include image/DTM name and end with _profiles), profiles parallel to the drawn profiles (filenames end with _profiles_parallel_n6_5m), points along all profiles (filenames end with _profiles_parallel_n6_5m_points), and points along profiles with the image DN, elevation, or hillshade raster values extracted (filenames end with _profiles_parallel_n6_5m_points_DN, _profiles_parallel_n6_5m_points_ELEV, profiles_parallel_n6_5m_points_VAL). Note that any profile ID ending with 01 was not used for the final analysis in the paper (only those numbered 02 or greater were included).profiles_with_geom: CSV files (filenames end with e.g. _profiles_parallel_n6_5m_points_DN_geom) which include the IDs for each profile, number from 0-5 indicating parallel profile number, offset distance between each parallel profile and the drawn profile in meters, distances along profile in meters, angle of the profile measured from north (in degrees), raster values extracted along profiles, and x and y coordinates for each point (in the map projection corresponding to the relevant image, orthoimage, DTM, or hillshade).profiles_lat_lon_elev: CSV files for each image including the profile ID, latitude, longitude, and mean elevation of the associated CCF (from Levy et al. 2014 data).profiles_fillthick: CSV files for each image including the profile ID and estimated fill thickness (in km) for the associated CCF (from Levy et al. 2014 data).profiles_angle: CSV files for each image including the profile ID and the angle of each profile from north (in degrees).CCF_crater_centers, which includes subfolders for files using map projections associated with the images and with orthoimages. These in turn contain the following subfolders:shapefiles: shapefiles for the center point of the crater associated with the CCF (filenames end with _centerpoint).csv_with_geom: CSV files (filenames end with _centerpoint_geom) including the x and y coordinates of the point at the center of the crater for the associated CCF (columns labeled xcoord and ycoord), the crater diameter (column labeled DIAM_CIRC_) from Robbins and Hynek 2012 data, and other information (unused) from the Robbins and Hynek 2012 database.miscellaneous_information, which includes the following files:CCF_HiRISE_profiles_categorization_v2: CSV file including image names, profile IDs, and the corresponding values for each category described in the methods (“Orientation Strength” and “Continuity” columns have values from 1-3 which correspond to low-high categorization; “Packetized” and “Distinguished Primarily by Negative Relief” columns have either y or n (yes or no) values)avgcategories_latlon: CSV file with latitude, longitude, and average orientation and continuity category values for profiles in each imagesCCF_HiRISE_image_name_lat_lon: CSV file with image names and center latitude and longitude for the CCF associated with each imageCCF_HiRISE_multiple_image_sites: CSV file with names of two images for CCF sites where two images were usedDTM_image_correspondence (and similar image_orthoimage_correspondence): CSV file including DTMs used for the study with the name of the corresponding image used (or images and corresponding orthoimages used)HiRISE_image_list, HiRISE_orthoimage_list, HiRISE_DTM_list: txt files with lists of all images, orthoimage, and DTMs used.The folder Output_Data contains subfolders for image, orthoimage, DTM, and hillshade wavelet analysis output. These in turn contain subfolders such as the following (not all subfolders included for each):significant_wavelengths_and_overlaps, which includes the following types of files:filenames containing summary_peaksigpow: CSV files with a summary of the significant wavelengths identified for each profile. This summary includes the wavelengths (in meters), the global wavelet power at each wavelength, length of the longest individual segment with significant power for each wavelength (relative to the wavelength), length of the longest individual segment with significant power for each wavelength (in meters), total distance over which each wavelength has significant power (relative to the wavelength), and the total distance over which each wavelength has significant power (in meters).filenames containing summary_overlap: CSV files with a summary of the significant wavelengths identified for each profile that overlap over some distance. This summary includes (for each pair of overlapping wavelengths): the shorter wavelength (in meters), the longer wavelength (in meters), the maximum continuous distance over which the wavelengths overlap (in meters), the maximum continuous distance over which the wavelengths overlap (relative to the longer wavelength), the total distance over which the wavelengths overlap (in meters), and the total distance over which the wavelengths overlap (relative to the longer wavelength).profile_crater_geom, which contains the following type of file:CSV files for each profile including: the x and y coordinates for each point along the profile, the radial distance from the center of the crater to the point in meters, the radial distance from the center of the crater divided by the crater diameter, the angle between each point and the center of the crater (measured from east, -180° to 180°), and for each significant wavelength identified in the profile (ordered shortest to longest), a zero or one value indicating whether the wavelength is significant at that point along the profile.figures, which contains the following type of file:figures (PNG file type) for each profile showing the profile I/F or elevation values vs distance (a), the wavelet power spectrum (b), the global wavelet power spectrum (c), and a plot of the length of the longest segment with significant power for each wavelength (d).overlaps_summaries, which contains the following types of files:significant_wavelengths_overlaps_evaluation_max_seg_dist: CSV files summarizing all profiles with overlapping wavelengths, including the image and profile name, shorter wavelength (meters), longer wavelength (meters), maximum continuous distance over which they overlap (relative to the longer wavelength), total distance over which they overlap (relative to the longer wavelength), and the ratio of the longer to the shorter wavelength. These files include just those pairs of wavelengths with a maximum continuous overlapping distance (relative to the longer wavelength) of at least 3.significant_wavelengths_overlaps_evaluation_sum_seg_dist: same as the above, but these files include those pairs of wavelengths with a total overlapping distance (relative to the longer wavelength) of at least 3.other, which contains the following files:filename containing lat_lon_minwavelen_maxwavelen: CSV file summarizing latitude, longitude, minimum wavelength (m), and maximum wavelength (m) identified for each CCF site.filename containing lat_lon_stdev: CSV file summarizing latitude, longitude, and standard deviation (m) of identified wavelengths for each CCF site.filename containing lat_lon_fillthick: CSV file summarizing the latitude, longitude, and estimated fill thickness (km; from Levy et al. 2014 data) for each CCF site.filename containing ks_es_theta0: CSV file summarizing statistical tests comparing the distributions of angular locations of profiles within craters for all profiles taken and for those with significant wavelengths identified (in both hemispheres, northern hemisphere only, and southern hemisphere only). This includes the number of profiles taken, the number of profiles for which significant wavelengths were identified, the Kolmogorov-Smirnov test statistic values, the corresponding KS test p-values, the Epps-Singleton test statistic values, and the corresponding ES test p-values.Preview_image.png corresponds to DTEEC_002175_2210_001410_2210_A01_EC02_n6_5m_wpsavg_sigavg_abspow_overnumwavelen3.png” in CCF_Ridges_Wavelet_Analysis/Output_Data/DTM_wavelet_output/figures.<br><br><br><br><i>For inquiries regarding the contents of this dataset, please contact the Corresponding Author listed in the README.txt file.
