Create a generic digital online tool to build Constant-Scale Natural Boundary (CSNB) maps of Vesta utilizing the Digital Elevation Model (DEM) found through Vesta Trek.


Why Vesta? Vesta is the only differentiated asteroid studied close-up to date, resulting in the availability of a digital elevation map for the object. It is relatively large, and somewhat less irregular than most asteroids. The Vesta Trek web portal provides visualization and analysis tools for exploration of the asteroid.


Constant-Scale Natural Boundary (CSNB) mapping is a revolutionary approach to visualization that produces maps markedly different from, and yet complementary to, those produced by conventional 2D cartographic and 3D modeling techniques. Conventional maps are built on predetermined grids or formulae that can distort features on both regular and irregular objects, such as asteroids. CSNB maps begin with those natural features as well-defined boundaries. To date, these maps are created using labor-intensive, and thus expensive, manual processes.

The Digital Elevation Model found in Vesta Trek can be used to develop or select and test linear feature recognition filters, applying them to find topographic/topological boundaries for Vesta.

Tip: Identify natural segments along constant scale boundaries, maintaining proportionality within segments. To create a 3D map, first create a 2D map and reconnect 2D segments into a 3D visualization model.

  • Major axes proportionally accurate to within 5%

  • Proportionally, surface area of actual object matches surface area of CSNB map to within 10%

  • Major features (asymmetries in hemispheres, large impacts, linear ridges and troughs) are represented in the 2D map as distinct "facets" or "segments"

That is to say, unbend the wire along a line connecting the wire with the object's center of mass.

Someone raised a question about dealing with segments of trees rather than the entire tree. Dealing with segments may be computationally easier than dealing with an entire tree. Here is a post addressing that subject:
