Surfer SRF Files

Page history last edited by Dr. Ron Eaglin 12 years, 5 months ago

 Surfer (SRF) Files

 

The contouring of the rainfall isohyetes was done with Surfer using a standard kriging algorithm. The surfer files contain all information necessary to add more contours if you have the Surfer software. Surfer version 8 was used and it is available from Golden Software. The final results are reported as word files and as shape files on the pages Kriging Analysis Results and Shape Files . The attached shape files have 81 separate files representing return period (2Y through 500Y) and durations (1HR to 5D). These files are generated from the grid files included at Grid Files

 

Surfer Files.zip

 

 

The script used to generate these is shown below.
