Hi everyone,<div>for the purpose of speeding up a complex interpolation (written in single core Fortran-code) we would want to split a cloud of points (ca. 3 million irregular points) into X number of parts (eg 20 parts of more or less 150 000 points). Does anyone know of some QGIS-extension that could do this kind of a job? </div>
<div><br></div><div>I was looking at a Saga-gis module ("Shapes - Tools > Split Shapes Layer Randomly") in the SEXTANTE toolbox. This is perfect if you want to split shapes into two parts with varying proportions between the two parts. I can perform this sequentially to arrive at the desired number of parts, but is very time consuming if you want to compare the impact on the system of splitting everything in eg 20 parts versus 15 or 12 or..</div>
<div><br></div><div>Preferably, a solution should be executable from the command-line.</div><div><br></div><div>Cheers,</div><div>Olav</div>
