Hi,
can you send me the error message that informs you about the limit? I
was just wondering because I did not add any restriction on the number
of input points in QNEAT3, neither in the n:n, nor in the m:n
algorithms. I have also performed analyses with more than 5000 points
per dataset (of course this analyses take much more time because of the
higher workload).
Best,
Clemens

Hi,
The QNEAT3 tool for 'OD Matrix from Points as Table' works perfectly
well for the problem. However, the API has limited access to points. I
have a set of 1400 points, whereas the API allows only 50 points for
matrix development. Is it possible to increase the access points?
Thanks and Regards,

Hi,
you could try the plugin QNEAT3 which supports network based
origin-destination matrices between points of one layer or
multiple sets
of points in two layers out of the box. The plugin is available
through
the QGIS plugin repository and gets loaded in the processing toolbox,
the algorithms you are looking for are called 'OD Matrix from
Points as
Table' or 'OD Matrix from Layers as Table'. The distance that is
output
to the matrix is measured based on the provided network layer.
For more info on the plugin you can checkout

I hope this helps!
Best, Clemens
