Mapping with Crusta

E-mail

Crusta provides real-time visualization of high-resolution topography and imagery. It now also supports mapping decorated polylines directly on the visualized 3D landscape similarly to applying decorated adhesive tape to a miniature model. This is demonstrated in the following video. The decorated polylines follow the topography exactly and distortions issues related to draping the adhesive tape and steep slopes are addressed. The symbols used for decorating the lines always retain their shape.

Data courtesy of:

  • Topographic - 1m DEM from Rochester Institute of Technology funded by World Bank
  • Topographic - ASTER 30m DEM of Hispaniola
  • Topographic - Blue Marble Next Generation funded by NASA's Earth Observatory
  • Imagery - Blue Marble Next Generation funded by NASA's Earth Observatory
  • Imagery - 15cm Google Aerial photography acquired January 17, 2010.

Enriquillo Fault Valley in LiDAR Viewer with Illumination

E-mail

This is a fly through of the Enriquillo fault valley, west of Port au Prince in Haiti. This video demonstrates the ability of LiDAR Viewer to create artificial hill-shades in real-time of point cloud data. The process of turning on illumination is demonstrated twice during the movie when the dialog boxes appear. The other transitions are edited to shorten the length of the video.

We recommend viewing this movie in a higher resolution. Due to the compression youtube uses, some of the quality of the video is lost. Click here for high res version (~44 mb) - http://haiti.geology.ucdavis.edu/videos/mp4_2048_fwest_illum.mp4

The LiDAR data are provided by the World Bank. This film was recorded on a Mac Pro Desktop with 2.93 GHz Quad-Core Intel Xeon and 3GB of RAM.

Demonstration of Crusta

E-mail

The following is a demonstration of a new visualization software package called Crusta. The program allows the integration of different resolution DEM and imagery data. The user can visualize these data in real-time. We hope this software will support rapid scientific response after disasters such as the Haiti earthquake.
