Elevation and slope statistics for the Mars Express HRSC DTM tiles used in Martian glacier work

01 Dec 2016 - MawKernewek


In the last post I noted the distribution of glacier-like forms according to elevation relative to Mars datum, and slope, as measured by the Mars Express HRSC DTM data.

One issue is whether the distribution according to elevation is a primary function of elevation, or the fact that the distribution of slope varies according to elevation in the area of study.

The distribution of slope and elevation was considered previously:



What will be needed however is the histogram of slope as a function of elevation. Below is a table of 179 HRSC DTM tiles that contain coverage of Souness objects, detailing mean, minimum and maximum elevation and slope, etc. A more comprehensive statistical assessment would use all HRSC DTM tiles that exist in the latitude range 25° - 70° that Souness studied.

Here are a couple of plots, showing the mean slope as a function of mean elevation, with errorbars, and the area of the plotting symbol proportional to the area of each tile, and a plot showing the proportion of each tile having slope exceeding 5° and 10° respectively.



Table of HRSC tiles


For comparison, the area of the UK is 243600km2. Several individual tiles are larger than this, the largest being h0533. The average area of each tile is 87055km2. Total area, ignoring overlap is 15.6 million km2, and taking account of overlap, it is 13.4 million km2. To find more about an individual tile, click on the link in the first column to the tile's page on Arizona State University's Mars Image Explorer or using HRSCview.
