High Resolution Voyager 2 Images of Neptune's Moon, Triton
We processed 41 Voyager 2 images of Neptune’s moon Triton with pixel scales < 2 km/pixel form their raw, compressed, archived state to more usable cloud-optimized geotiffs, which can easily be used within spatial analysis software such as GIS. Processing was done using the USGS’ ISIS software and included geometric and radiometric calibration, and the removal of image reseaux and corner markers (originally used for geometric calibration). The images were also photogrammetrically controlled relative to one another to improve their locations on the surface, which were initially inaccurate by up to 200 km. After performing a least squares bundle adjustment, the root mean square (RMS) uncertainty in image locations was 0.50, 0.52, and 0.51 pixels in latitude, longitude, and radius, respectively, with minimum and maximum residuals of -4.21 and +3.197 pixels, respectively. Each individual image was warped to an orthographic projection centered at 15o W and 18o N at the native image resolution. Because reseaux removal introduces interpolated data, two versions of each image are provided: a fully processed version with reseaux removed, and a partially processed version that retains the reseaux (i.e., no interpolation). We also generated a mosaic of Triton images that is spatially consistent with the entire dataset and provides context for the individual images (not every image is included in the mosaic). The mosaic uses the same orthographic projection as the individual images, but a consistent scale of 600 m/pixel. Three versions of the mosaic are included: a fully processed version (reseaux removed, some interpolated pixel values), a partially processed version (reseaux retained, no interpolation), and a fully processed but sharpened (high pass filter with 100% albedo add-back) to enhance surface features. This data release improves the usability and accessibility of this singular dataset and enables new scientific investigations of Triton.

Photogrammetrically Controlled, Equirectangular Galileo Image Mosaics of Europa
공공데이터포털
The Solid State Imager (SSI) on NASA's Galileo spacecraft acquired more than 500 images of Jupiter's moon, Europa, providing the only moderate- to high-resolution images of the moon's surface. Images were acquired as observation sequences during each orbit that targeted the moon. Each of these observation sequences consists of between 1 and 19 images acquired close in time, that typically overlap, have consistent illumination and similar pixel scale. The observations vary from relatively low-resolution hemispherical imaging, to high-resolution targeted images that cover a small portion of the surface. Here we provide average mosaics of each of the individual observation sequences acquired by the Galileo spacecraft. These observation mosaics were constructed from a set of 481 Galileo images that were photogrammetrically controlled globally (along with 221 Voyager 1 and 2 images) to improve their relative locations on Europa's surface. The 92 observation mosaics provide users with nearly the entire Galileo Europa imaging dataset at its native resolution and with improved relative image locations.
Lunar Orbiter Photo Gallery
공공데이터포털
The Lunar Orbiter Photo Gallery is an extensive collection of over 2,600 high- and moderate-resolution photographs produced by all five of the Lunar Orbiter missions. These photographs were taken in 1966 and 1967 to survey possible lunar landing sites and provide baseline imagery for geologic analysis of the lunar surface. The images were used to select the Apollo landing sites and to produce many of our existing lunar geologic maps. This photo gallery is the web's most comprehensive collection of Lunar Orbiter photography and supporting documents.
