Origin Ver. and Service Release (Select Help-->About Origin): OriginPro 2021 (64-bit) 9.8.0.200
Operating System: Win10
I have geolocated lidar backscatter data from a flight that i need to plot. The data are functions of time (T) and Altitude: Longitude(Time),
Latitude(Time),
LidarData(Time,Altitude).
The number of Time data points is about 20,000 (entire flight) and number of Altitude data points is 600 (from the ground to 9 km in 15m increments). So the array dimensions are:
Longitude(20,000),
Latitude(20,000),
LidarData(20,000,600).
For each Time T have a location (Longitude, Latitude) and LidarData at that location that extends from the ground to 9 km (600 points).
Is there a way to make a color-coded 3D (curtain) plot for these data? |

| Not quite understand how the LidarData part looks like. But maybe you can do a 3D line with (X,Y,Z)=(Longitude,Latitude,Altitude) and map the color to the timestamp. |

Here is what the data looks like:
Longitude(T),Latitude(T), Lidar(T,600)
so for each time T I have a single Longitude and Latitude data point but i have 600 data points in the Z direction from 0 to 9 km (think of it as a column or "curtain").
A 3D line (or surface plot) with (X,Y,Z) data plots only one Z data point for each X,Y. I have 600 Z data points for each X, Y. I hope that helps. |

Hello,
Can you share one such file with us please?
Then we can be sure of the data arrangement and see if the plot is feasible without further rearrangement of the data.
You can go to this page:
https://www.originlab.com/restricted/support/index.aspx
and submit a ticket item and attach your file to that ticket.

I created an Origin file with the data but it is 42 MB and is rejected.
Message was "The page was not displayed because the request entity is too large."
If you could provide me with an email I have a way to securely share the data file with you.
thank you |

Sorry about that. We bumped up the limit.
Please try again.
Also you could zip up the file if that helps reduce the size.
Thank you,

I am afraid it still does not work. The zip file is 40.2 MB but i still get the same message using two different browsers: "The page was not displayed because the request entity is too large".

Could you upload it to our dropbox link?

Best,

I am afraid dropbox is not allowed at the agency I work at (it's blocked). I can share the file via Google drive or other secure download link but I will need an email address. You can email me directly with an email address. |
