GEOPS/IPSL DaCHS Server TAP service
The GEOPS/IPSL DaCHS Server's TAP end point. The Table Access
Protocol (TAP) lets you execute queries against our database tables,
inspect various metadata, and upload your own data. It is thus the
VO's premier way to access public data holdings.
Tables exposed through this endpoint include: epn_core from the exotopo schema, epn_core from the pretharsis schema, columns, groups, key_columns, keys, schemas, tables from the tap_schema schema.

EXOTOPO
"The data consists in topographic maps of synthetic 3D bodies
generated by a 3 parameters statistical model : the fractionally
integrated flux (FiF) (Lavallee, D., Lovejoy, S., Schertzer, D.,
Ladoy, P. (1993). Nonlinear variability and landscape topography:
analysis and simulation) adapted for spherical coordinates and
topography (Landais, F., Schmidt, F., and Lovejoy, S, (2018)
Topography of exoplanets, MNRAS). The 3 parameters are the following :
H: degree of smoothness; C1: degree of intermittency; alpha: degree of
multifractality; The service contains topographic maps (in Fits
format) and texture maps (in png format)."

PRETHARSIS
"The growth of the Tharsis volcanic complex on Mars during
Noachian/Hesperian era induced a reorientation of the spin axis of the
planet (true polar wander). This service gives access to a map of Mars
topography before Tharsis formation (Early Noachian) and a map of Mars
topography before true polar wander (Late Noachian/Early Esperian),
from the model described in Bouley, S., Baratoux, D., Matsuyama, I. et
al. Late Tharsis formation and implications for early Mars. Nature
531, 344â347 (2016). https://doi.org/10.1038/nature17171 ."
