How to get a location one event statistically?

Dear All,

I have the column vectors of latitude and longitude as well as the event. I am interested in getting the statistical result for those events greater than threshold. I want to see where the majority of these events is situated so that I can estimate it in the map (the region of my interest). I also want to know how often I would observe it?

Would you please inform me the best approach in order to solve my problem?

I would appreciate your help,

Best regards,

Ara

I suspect you might find a "heat map" or "density map" to be useful; https://www.mathworks.com/matlabcentral/answers/310801-how-to-plot-the-brightness-lines-in-matlab-as-this-picture#answer_242120

Hello Walter,

Nice to see you here, again;I hope you are doing well!

Thank you for your suggestion. I tried but I could not plot it correctly. My problem is I have two type of datasets from ground and space and I want statistically get events from each sets of data and then all together plot in map to see whether I can find any correlation or not in terms of the geographic location.

I have loaded the data, where I have the column vector of event named as "dataFiltered.s4" with latitude "dataFiltered.lat", and longitude"dataFiltered.lon". I examine one way, which means floor the time and then count events by getting the accummarray of those events greater than the threshold. But, it was not a good idea. I tried to use your code "please see here here "

But, all of my data is sorted in columns only. So, would you please tell me how to adapt it to only read column vector?

Thank you,
