More decorative than useful, as the 5-metre contour lines are so close-spaced they dominate the image. I used a continous colour-ramp for the contours, so the lowest are green, intermediate altitudes are yellow and the highest altitudes are orange.
Most of the image is occupied by the undulating plateau of the Atherton Tableland, but in the northeast corner are some of the steep valleys that cut into the Great Escarpment that forms the seaward edge of the tableland.
Geologically, the surface of the tableland is mostly flood basalt, breaking down to form sticky bright red clay soils, while the mountains on the eastern edge, and the escarpment itself are a mix of granite plutons and associated contact metamorphics of sedimentary origin - the Hodgkinson Formation.
The Tinaroo Dam was built in the 1950's to provide irrigation water for the tobacco industry and the town of Mareeba. With no tobacco being grown now in Queensland, the water is currently used for bananas, mangoes, avocadoes and coffee.
Lakes Eacham and Barrine are maars (craters left by volcanic explosions). The tableland also has several small cinder-cones, around Yungaburra.

This schematic describes how glaciologists are studying the mass changes and dynamics of large glaciers and ice caps using a combination of remote sensing and in-situ measurements.
Altimeters onboard artifical satellites, aircraft or UAVs measure changes in the height of the glacier surface. Since glaciers deform under their own weight, they flow from top to bottom. The flow trajectory has both vertical and length-wise components. These deformations have to be accounted for when comparing altimeter measurements that are, for example, one year apart.
