Contour map generation is now multi-threaded, optimized, and is 7 times faster! If you use large grid files or display your data with a close contour interval, these efficiency improvements will save you a ton of time. The updated progress gauge now lets you know exactly how much time to wait.
Grids/Data/Image files are shared between maps
This makes your SRF project both smaller and faster. If you use the same input file for multiple map types (a color relief and contour map, for example), these files are now shared rather than being duplicated n your SRF project file. The same applies for vector files and image files. When creating a new map layer in Surfer, you can choose whether to use a new file, or one that's already saved into your project.
