without elevated geothermal heating2. These findings offer independent support for the presence of basal water beneath Ultimi Scopuli and suggest that surface topography could supplement radar returns to help identify other potential subglacial water bodies.

A map scale of 1:63,360 is common in Forest Service maps, and maps throughout Alaska. These are smaller-scale maps, with less intricate detail. Some National Geographic maps use a scale of 1:65,000, which allows a large area of land to be packed onto a single topo map. What you n...

LocationA good map must accurately show the locations of the features present in the area that it covers,and should ideally locate that area in the larger picture--on the Earth as a whole. Most roadmaps use a simple grid system involving letters and numbers to locate cities and towns.Latitu...

The data grid has a resolution of 1 arc-second (approximately 30 m) and is referenced to the WGS84/1996 Earth Gravitational Model (EGM96) geoid. Although the ASTER GDEM v. 002 is a better model than ASTER GDEM v. 001, users have to know that the data may still contain anomalies and...

Here's a flat topographic map laid over a Google Map 3D model. You can see that the lines match the slope of the mountains and canyons. Want to overlay topographic maps onto a 3D Google Earth model so you can explore yourself? And even put your hike route on there? I'll show you ...
These maps are called 7.5 minute quadrangle maps because each map covers a four-sided area on the surface of Earth that is 7.5 minutes of longitude wide and 7.5 minutes of latitude high, where 60 minutes equals one degree of angle. Because the distance between longitude lines gets narrower ...
a planet's atmosphere from being stripped away by solar winds (it's the same thing thatprotects the Earth from harmful solar flares). Without it, Mars' carbon dioxide atmosphere was either blown away into the inky depths of space or locked into the surface in the form of carbonate minerals...
