Orion™ 2.1 for Windows

Measure Attitudes of Geological Strata and Other Structures Using Satellite Imagery

***** NEW VERSION *****

Orion™ for Windows uses satellite images together with gridded topographic data to help you compute the structural attitude of geological strata or other planar structures. The program calculates the attitude from three or more points selected by point-and-click for a lithological contact or fault surface seen in the image.

Image Formats:
TIFF, GeoTIFF, JPEG, Windows BMP, PCX, PNG, Targa TGA, Planetary Data IMG and VICAR **NEW!**

Gridded Elevation Data Formats:

BIL (with HDR header), ASCII XYZ grid, ArcInfo® ASCII Grid, Planetary Data IMG and VICAR **NEW!**

How It Works:
Using an interactive mouse tool, click on selected points along the geological contact in the image. Orion computes the best-fit plane through those points and shows the fitting statistics with their confidence limits. Check your fit by looking at the fitted surface trace across the image. You can also see the fitted plane in a 3D block view. Then add, delete and move the selected points until you are satisfied you have the best fit possible. Once you accept and save the measurements, Orion then plots the result on the image as a strike/dip or dip-direction/dip symbol. You can analyze a group of measurements projected on a customizable stereonet and perform basic structural analysis by computing the principal directions of the fitted planes and contouring their density distribution.

A Sample Application of Orion:

Structural Attitude of Layering in Valles Marineris, Mars

Dr. Paula MacKinnon, Dr. Frank Fueten (both of Brock University, St. Catharines, Ontario) and Dr. Bob Stesky (Pangaea Scientific) are using Orion 2.1 to estimate the attitude of strata visible in the gigantic Valles Marineris chasm on Mars. Working with scientists associated with the European Mars Express mission's High Resolution Stereo Camera (HRSC) project, they are analyzing high resolution imagery and digital terrain models of the Martian surface. They have already published one paper, have submitted a second for publication and are presenting the latest results at the 37th Lunar and Planetary Science Conference in Houston, Texas. The two recent abstracts are available as PDF files: Candor (743 kb) and Coprates (413 kb).
