Automation of Morphometric Measurements for Planetary Surface Analysis and Cartography

Abstract

ABSTRACT:For automation of measurements of morphometric parameters of surface relief various tools were developed and integrated into GIS. We have created a tool, which calculates statistical characteristics of the surface: interquartile range of heights, and slopes, as well as second derivatives of height fields as measures of topographic roughness. Other tools were created for morphological studies of craters. One of them allows automatic placing of topographic profiles through the geometric center of a crater. Another tool was developed for calculation of small crater depths and shape estimation, using C++ programming language. Additionally, we have prepared tool for calculating volumes of relief features from DTM rasters. The created software modules and models will be available in a new developed web-GIS system, operating in distributed cloud environment.

Relief of Mercury and the Moon: From Morphometry to Morphological Mapping

“…For the purposes of our study we mostly use two of them: -Interquartile range of the second derivative of heights. To calculate this parameter we use a previously developed tool integrated into the ArcGIS software (Kokhanov et al, 2016).…”
