CartieSim, the SCA's cartie speed calculation application, just got better. Version 1.1.0.8 has just been released and includes some significant improvements;

• Added distance v. time chart
• Much improved calculation of elevation data from online satellite data sets (SRTM and ASTER). Elevation is now interpolated from nearest 16 data points using bicubic interpolation
• Modified formula and algorithm for determining speed to better account for the effect of wheel mass
• Added modelling of drag plates (for Cairngorm)
• Default new cartie data can be saved
• Automatic insertion of extra course datum points on long straights to give better resolution of the elevation profile
• Automatic detection and marking of corners
