Re: Trajectory "Hits" ground

Thank you for your answer. I just running a back dispersion calculation instead of a single trajectory like you said , the height of some trajectories which i need their data of height still hit ground ,how can i solve this situation? Delete these trajectories or averaging these data of height?

Re: Run Cluster on different origin lat-longtitude

Thanks for your answer! But I must cluster in a area that mean the origin start point must be differ. Is there some measures to do like it? Somebody tell me if i can shift the original point into one start point which have the same latitude and longitude? Is it useful? Or can you tell me how to shif...

Run Cluster on different origin lat-longtitude

Hello all, Pardon my poor English, I have chosen 36 origin points in 3 levels of 500m/1500m/3000m in the area of 27.5-32.5N/100-107.5E. After i push the cluster button, It gives me an error like this: ERROR - origin lat-lon for all trajectories must be identical. Differs in tdump... but I am sure th...
