Hi Giuseppe,
Would it be possible for me to get a copy of the test data you are using to
build your DTM? I'd like to try using my Natural Neighbor
Interpolator (NNI) implementation on it and see what the results look like.

Hi Jukka Rahkonen,
I am impressed that you were able to download and test the demo application
so quickly.

The results were slower than I expected. I want to investigate and see if I
can improve the processing time. Also,
Hi Gary
Here you can find the source code of my algorithm,
https://sourceforge.net/p/opensit/code/HEAD/tree/Projects/Raster%20tools/OpenJUMP%201.16/src/org/openjump/core/rasterimage/algorithms/rastercreation/interpolation/
As sample if you want to try to port your code to Openjump

Hi Gary,
Thanks for your work
I have been working to an interpolation plugin of point data (loaded in
openjump as shape files) to a DTM raster.
I used the code from s former ImageJ plugin (
https://imagej.nih.gov/ij/plugins/xyz2dem-importer.html)
which was quite fast and very flexible.
The
hey Gary,
thanks for the offer. any contribution to OJ is welcome and pointing out an
interesting libraries surely might incentivize somebody to include it's
functionality.
you maybe wanna open an issue on https://github.com/openjump-gis so it might
get indexed by search engines?
..regards
Hi,
Thanks, this is very interesting. I downloaded the demo and had a try with our
point cloud data with one .laz file and it was opened and shown fine:
Name: W4323G3.laz
Type: Lidar (GroundPoints)
Vertices: 6564001
Load time(ms): 31068
Sort time(ms):1898
I am sending this email to make a modest offer to the OpenJUMP developer
community.
I’ve written a Java library for processing Delaunay triangulations that may
be useful for OpenJUMP. The Tinfour open-source software API is
sufficiently fast to handle large unstructured data sets such as Lidar. I
