Phil,
The Shape Tools plugin has an "Azimuth distance digitizer" and for what you
are talking about an "Azimuth distance sequence digitizer". With the latter
function you click on a starting location and then give a list of azimuth,
distance sequences. I have used this for old surveys like this. T

In a month I will be retiring from US federal government service. For the

government use. I've had some success but wish it would have been easier. I

I have been working on a plugin and as a part of its capabilities is to be
able to use a .qml file or the style on the clipboard to apply it to all
selected layers including groups of layers. It would be a very similar
process to adjust the opacity or stroke style.

Once you have your centroids you can use the Lat Lon Tools plugin and run
the "Point Layer to Fields" algorithm to extract the geometry and add it to
one or two attribute fields. You can also specify the CRS that you want it
in and what format (ie. decimal degrees, DMS and a lot of other formats)

Creating a KML that large is usually not a good idea, but if you still want to

Anyone dealing with heatmaps or density estimation will be interested in
this plugin.

QGIS natively has the Heatmap (Kernel Density Estimation) algorithm
which is powerful and produces a heatmap image that can then be styled and
displayed. Each pi

With raster styling there are only "Interpolation" options Discrete, Linear

The Lat Lon Tools plugin has a coordinate display dialog where you click on
a point and it displays it in many different coordinate systems.

Hi QGIS users,
I am looking for ideas for what QGIS development I should be working on

I am wondering whether it is time to remove my QGIS 2 plugins from

they are not, they should be. What are your thoughts? All of my QGIS 2
plugins are much less capable than my version 3 plugins.
Thanks,

I don't know about that question for sure, but I suspect that if they were
not ported to QGIS 3 then they are not likely being used. Some plugins
became deprecated because QGIS 3 integrated their capabilities into
its core algorithms. In my case I ported all my QGIS 2 plugins to QGIS 3.

I'm surprised that QGIS 2 is still being used. In that case I will leave my

You can always use the Shape Tools plugins to draw a circle around the
points. It uses Geodesic calculations so you don't need to convert to
another projection.

I came across a point vector layer that had a WKT object as one of the
attributes. The WKT object could be a point, line, polygon, multi-point,
multi-line, or multi-polygon and there could be a mixture of these in the
same vector layer.

Use the "Density Analysis" plugin. It solves this very problem, but you
will want to install the H3 library to get really fast hexagons. Look at
