Updated database of craters on Mars with pitted impact deposits

This point-based database (provided in two formats: as a ESRI shapefile set and simple .csv) currently contains 309 craters on Mars that possess “crater-related pitted materials” (CRPM), which are consistent with impact deposits described in detail in Tornabene et al. (2007; 2012). The Tornabene et al. (2012) publication is the original source of the initial database of 204 craters, which was based on a survey by the Mars Reconnaissance Orbiter (MRO) over a period of late 2006 to early 2012. MRO continues to image the surface and its craters, as such the database has since grown from 204 to 309 entries to date. Despite this growth, the general characteristics of the crater population remains generally consistent with what is described in Tornabene et al. (2012) (e.g., size range, latitudinal and elevation distribution, etc.). When present, these pitted impact deposits represent the upper most surface of the crater-fill with the pits potentially representing top-down views of so-called degassing pipes observed only in eroded cross-sections at some terrestrial impact structures such as the Ries in Germany (e.g., Caudill et al., 2021). Therefore, the craters that contain pits and preserve them well are themselves amongst the very best-preserved and often youngest craters of their size-class on Mars. Indeed, some of these craters are observed to have far-reaching (10s to 100s of crater radii) thermal / secondary crater rays (e.g., Tornabene et al. 2006), which is considered to be a feature associated with only the best-preserved and youthful craters on planets/moons with solid surfaces. These craters have enabled us to place further constraints on the scaling of crater depth as a function of diameter for complex craters on Mars (Tornabene et al. 2018) and may even help us to ultimately determine where the only samples we have of Mars — the Martain Meteorites — come from. See README rtf file for further details on the database.   Versions 8.21.2025: 4th version - deleted 3 additional duplicates (Lunae, Oudemans and Toro) total entries is now 309 8.20.2025b: 3rd version upload - fixed 1 duplicate (312 entries), caught some additional updates with respect to new official crater names, and CTX image IDs. 8.20.2025: 2nd version with an increase to 313 entries with some updates to preservation ratings, image IDs, etc. 5.3.2023: 1st version uploaded with 300 entries   Main references (*original/source  database): *Tornabene, L.L., Osinski, G.R., McEwen, A.S., Boyce, J.M., Bray, V.J., Caudill, C.M., Grant, J.A., Hamilton, C.W., Mattson, S. and Mouginis-Mark, P.J., 2012.

Internal morphology point clouds of lunar pits

This archive contains point clouds showing the internal geometry of six pits on the Moon.  These point clouds were generated via manual feature matching in "oblique stereo pairs": pairs of Lunar Reconnaissance Orbiter Narrow Angle Camera (LROC NAC) images at two different off-nadir angles observing one wall of a pit under similar lighting conditions.  These images have pixel scales of ~0.3-2.2 m/pixel, allowing the creation of point clouds with point spacing on the order of 5-10 m, depending on the density of identifiable features on the pit walls. The manually-generated point clouds from multiple stereo pairs have been merged together, and aligned to and merged with dense digital terrain models (DTMs) from more nadir-looking NAC stereo images where available, to produce point clouds that cover the upper walls, floors, and immediate surroundings of the pits. For a full description of the processing method, see Wagner and Robinson (2022), linked in this archive's metadata. This archive contains models for the following pits: Lacus Mortis Pit (LMP) Mare Ingenii Pit (MIP) Mare Tranquillitatis Pit (MTP) Marius Hills Pit (MHP) Schlüter Crater Pit (SCP) Southwest Mare Fecunditatis Pit (SWFP)
