    An Improved Global Catalog of Lunar Impact Craters …

    What is the global catalog of 106016 impact craters?
    Compiled a global catalog of 106016 impact craters with comprehensive morphometric parameters. Inspected the asymmetric spatial distribution of impact craters. Using Chang'E-1 images and a digital elevation model, we have compiled a global catalog of 106016 impact craters with diameters greater than 500 m.

    A Chang'E-1 global catalog of lunar impact craters

    Using Chang'E-1 images and a digital elevation model, we have compiled a global catalog of 106016 impact craters with diameters greater than 500 m. For all the craters, we integrated all the morphologic attributes available and examined the distribution of craters to identify and investigate potential spatial asymmetries.

    The Laser Altimeter (LAM) instrument on board the Chang'E-1 (CE-1) lunar-orbiting satellite provided accurate measurements of lunar topography and the three-line digital photogrammetric CCD stereo camera provided global imaging of the Moon. The imaging data were combined to produce a global 120-m-pixel mosaic of the Moon and a lunar Digital Elevati...

    The database was compiled by identifying craters in a hybrid crater detection algorithm (CDA) based on DEM and optical images. First, we used the integrated intensity-based DEM construction approach introduced by Grumpe and Wöhler (2011) that relies on DEM data of low lateral resolution and high-resolution image data to obtain a pixel-synchronous D...

    This paper presents a significant new catalog, LU106016, of lunar craters (the most complete record of craters with diameters≥500 m), which contains a considerably larger number of craters and associated attributes than any other currently available catalog. Overall, the true detection rate is estimated at 75.8%, an increase of 35.4% over the average numbers represented in other catalogs. Also, the Receiver Operating Characteristics (ROC) curve, which deciphers the robustness of the algorithm, shows that the area under the ROC curve is between 0.7 and 0.9, meaning that the CDA provides better results (Fig. 2). Due to imaging illumination conditions and insufficient spatial coverage, fewer small craters (≤1.5 km in diameter) are presented in our catalog (47% less) than in the LU78287 catalog (Salamunićcar et al., 2014). However, our system has identified 26351 new craters >3 km in diameter that are not listed in LU78287. As suggested by Robbins et al. (2014), features consisting of at least 10 pixels are required to produce reliable and complete measurements; the greater number of craters guarantees that the catalog is an improvement over other records. An additional comparison of the results and an assessment of completeness was to take the size distribution of craters into account. As shown, the values that are obtained for the overall data set, and also the negative slopes, are consistent with previous size-frequency distributions determined for the lunar crater population from other crater catalogs (Fig. 2). …
