This is fantastic information. I'm going to dive in and see what I can
discover. Automatic conversion of the model to Python script is definitely
neat! Really appreciate this awesome forum and the availability of QGIS!
Best to all,

Hi,
Users of this group will give you good information on the QGIS Python api. You
can use that.
Another way is to use the python Shapely library. Using the object.bounds
method, you will have you xy min and max coordinate. If you use the geopandas
library, you can use he same shapely
Hi,
It’s difficult to help without knowing how the data is organized (ex number of
people are points data, polygon data, 1 points per person vs aggregated data..)
You can search for grouping, cluster analysis, heat map, voronoi polygons,
concave hull.
Once you have polygons you will need to

many of us with the wrong CRS or reversing the easting and northing. I

Hi -
Wondering if there is existing Python(3) script code that can take an (ESRI)
shape file as input and then calculate latitude/longitude/elevation values
for country boundaries. For example, if the input file is a SHP file for
France, the output would be the lat/lon/elevation values for the

Dear,
I am using PyQGIS in QGIS 3.10 and I am working on a script to standardise and
automate heatmap creation. Currently, the only way (by my knowledge) to
reclassify rasters in QGIS (through the Processing Toolbox) is with r.reclass
or the SAGA reclassify values (simple and 'not simple').

ok. I don't call that an error; I call it matching. As an experiment,
find a physical point you can reoccupy, and on 10 days not all at the
same time of day go take a measurement and then tell us the statistics

Hi,
Thanks for the precision. So they are basically prone to the same problem
(which is reassuring). My guess is that the true befits is that they add a
compass with the barometer so you can take a heading reading when not moving...
I guess that is worth 100 bucks!
Guess we’re moving
Hi Nicolas.You can set the barometer my using a known point and elevation or by
setting the current atmospheric pressure. As with an anologue altimeter, your
readings will change throughout the day as the pressure changes. This is less
of a problem if you are out on a sunny day with a high
Hi,
Interesting but I very much doubt they are not applying a geoid on top of the
ellipsoid. If they can put maps of the earth on the device, they can put a
geoid with a posting of 15´x15´!
I have been wondering about those barometric altimeters GPS for back packing.
I have a none
Hi jean:
Another issue is that you can set your elevation reference point in most
Garmin units to either use the height above the ellipsoid or and
approximation mean sea level. This setting will also have an impact on
your observed elevation.

Good morning,
I created 2 users on my database.
one admin and one read-only.
The read-only one still allows me to edit and delete.
I get the message "this user does not have the permissions, contact the
administrator of the database", but does the modification anyway.
I have tried closing qgis
