A Global Catalog LU1319373 of Lunar Craters (≥ 1 km)

A global crater catalog LU1319373 that includes approximately 1.32 million lunar craters with diameters ≥ 1 km. The crater catalog also include 3D morphometric data on the craters.

This version of the crater catalog LU1319373 includes the following information for each crater:

• Longitude and latitude coordinates of the center;
• Crater diameter;
• Crater depth.

The lunar crater catalog LU1319373 can be downloaded from here.

Rock Measurements at Zhurong Landing Site on Mars

The dataset includes ortho-image mosaics and rock measurements at the Zhurong landing site on Sols 3-6 and Sol 40.

The ortho-image mosaics were generated by photogrammetric processing of the stereo images taken by the Navigation and Terrain Camera (NaTeCam) onboard the Zhurong rover. Based on the ortho-image mosaics, rocks (≥ 5 cm) were measured with their diameters and areas, which indicated a rock abundance of ~ 5% at the Zhurong landing site. Details can be found in the related publication (Chen et al., 2022).

The dataset can be downloaded from here.

3D Rocks at the Zhurong Landing Site on Mars

The dataset includes 3D rocks (point clouds) with various 2D/3D morphological features at the Zhurong landing site on Sols 30-31, 64-65, 103-104, 172-173, 204 and 259-260, and the associated digital elevation models (DEMs).

The 3D point clouds were initially generated by photogrammetric processing of the stereo NaTeCam images taken by the Zhurong rover, and then was resampled from the triangular irregular network with a fixed step to generate a new 3D point cloud with even density. 3D points corresponding to rocks were further extracted and clustered as connected components. In total, 6,185 centimeter-scale rocks were extracted as 3D point clusters through the concavity-based watershed and morphological refinement. Details can be found in the related publication (Li et al., 2023).

Maps of Ganymede: New Control Point Network, Global Mosaic, DEMs

Set of multilingual maps of Ganymede based on photogrammetric processing of the best images provided by different space missions to Jupiter system – Voyager -1,2, Galileo and JUNO.

The previous control point network (CPN) of Ganymede was updated, and now includes more than 2,050 points. Based on updated CPN, a new mosaic and local DEMs with a vertical resolution of better than 1 km were obtained. Using these data multilingual maps of Ganymede were created: a global map (with equatorial and polar regions) and detailed large scale maps of selected sites of interest (surroundings of Tros crater, Phrygia Sulcus and Enki catena). Details can be found in the related publications (Zubarev et al., 2022; Melnikova et al., 2022).

The maps can be downloaded from here.
