This repository contains a high-resolution geomorphological dataset developed to support quantitative analyses of small-scale conical landforms interpreted as scoria cones on Mars and Earth and to validate the performance of MarsCONE 2.0. The dataset covers four volcanic regions selected to evaluate the applicability of the algorithm across planetary environments: Ulysses Colles and Hydraotes Colles on Mars, and the San Francisco Volcanic Field (Arizona, USA) and the Michoacán–Guanajuato Volcanic Field (Mexico) on Earth. The core component of the dataset consists of digital elevation models (DEMs) derived from stereo pairs acquired by the Context Camera (CTX) and the High Resolution Imaging Science Experiment (HiRISE) aboard the Mars Reconnaissance Orbiter. These DEMs have ground sampling resolutions of 12 m px⁻¹ and 1 m px⁻¹, respectively. For the Ulysses Colles volcanic field, the CTX DEM was generated from stereo observations P19_008262_1862 and F18_042652_1855, centered at 6.27°N and 236.97°E and 5.6°N and 237.07°E, respectively. These images were processed within the MarsSI framework to produce DEM CTX_008262_1862_042652_1855, centered at 6.071°N and 236.989°E. The individual CTX stereo images are publicly available through the NASA Planetary Data System (PDS) portal: https://ode.rsl.wustl.edu/mars/productsearch. High-resolution topographic data were obtained from four HiRISE stereo pairs: ESP_042652_1855 and PSP_008262_1855, PSP_009409_1860 and PSP_009554_1860, ESP_053926_1860 and ESP_059689_1860, as well as ESP_055126_1865 and ESP_055482_1865. These stereo pairs were processed using the Ames Stereo Pipeline (ASP) to generate the DEMs HI_008262_1855_042652_1855, HI_009409_1860_009554_1860, HI_053926_1860_059689_1860, and HI_055126_1865_055482_1865, centered at 5.656°N, 237.025°E; 5.804°N, 237.162°E; 6.060°N, 236.971°E; and 6.396°N, 236.965°E, respectively. The original HiRISE datasets are publicly accessible through the Lunar & Planetary Laboratory (LPL) HiRISE website: https://www.uahirise.org/hiwish/browse. For the Hydraotes Colles volcanic field, the CTX DEM was generated from stereo observations G02_019124_1803 and G03_019269_1803, centered at 0.4°N and 326.03°E, respectively. These images were processed within MarsSI to produce DEM CTX_019124_1803_019269_1803, centered at 0.385°N and 326.040°E. The individual CTX stereo images are publicly available through the NASA Planetary Data System (PDS) portal: https://ode.rsl.wustl.edu/mars/productsearch. High-resolution topographic data were derived from three HiRISE stereo pairs: ESP_021458_1800 and ESP_013177_1800, ESP_025493_1800 and ESP_017634_1800, ESP_039550_1805 and ESP_039484_1805. Processing with the Ames Stereo Pipeline resulted in DEMs HI_013177_1800_021458_1800, HI_017634_1800_025493_1800, and HI_039484_1805_039550_1805, centered at 0.055°N, 326.191°E; 0.101°S, 326.325°E; and 0.448°N, 326.744°E, respectively. The original HiRISE datasets are publicly accessible through the Lunar & Planetary Laboratory (LPL) HiRISE website: https://www.uahirise.org/hiwish/browse. The second component of the dataset comprises terrestrial DEMs representing scoria cones within the San Francisco Volcanic Field. These datasets have ground sampling resolutions of 30 m px⁻¹ (Copernicus GLO-30 DEM), 10 m px⁻¹, and 1 m px⁻¹. The latter two DEM datasets were acquired by the U.S. Geological Survey (USGS) as part of the 3D Elevation Program (3DEP). All datasets are publicly accessible through the USGS The National Map (TNM) portal: https://apps.nationalmap.gov/downloader/#/elevation. For the Michoacán-Guanajuato volcanic field (Mexico), DEM datasets with ground sampling resolutions of 15 m px⁻¹, 5 m px⁻¹, and 1.5 m px⁻¹ were used. These datasets were derived from the Continuum of Mexican Elevations and Digital Elevation Models (CEM 4.0) and from photogrammetric point clouds generated using high-resolution satellite imagery acquired in stereoscopic mode. All datasets were publicly provided by Mexico’s National Institute of Statistics and Geography (INEGI): INEGI Relief and Elevation Data Portal https://en.www.inegi.org.mx/temas/relieve/continental/#downloads. In addition, this repository includes a shapefile (.shp) containing point features marking the locations of pitted cones identified by an expert for automatic morphology detection using the MarsCONE 2.0 software toolbox.
