4.4.0: [20260817] GeoProfiler: added projection of earthquake focal
mechanisms, plotted as beachballs either in map view or rotated into
the section plane, with their own style (quadrant colours, size,
outline, alpha, labels) and export/import to the profile database
[20260817] GeoProfiler: point and focal mechanism projection can now
read the vertical field as a depth instead of an elevation, measured
either from sea level (default) or below the topographic surface from
a DEM, in km (default) or m, converted to elevation for plotting
[20260817] GeoProfiler: projection of large datasets is orders of
magnitude faster (collinear segments of densified profiles are
collapsed, and points beyond the maximum distance are excluded by a
buffer pre-filter before any projection); the progress bar now
advances per block of points, over the whole run, instead of once per
profile
[20260817] GeoProfiler: fixed saving and loading of graphical
parameters, which failed on save and returned unusable parameters on
load; fixed projection along individual axes, which used the axis of
an arbitrary profile segment instead of the one given for each point;
fixed attitudes being paired with the wrong elevation when a record
had no valid one; made focal mechanism labels legible; removed
unreachable duplicate point-projection code
[20260817] GeoProfiler: a single profile can now be exploded into its
own window, with the full height to itself instead of a sliver of the
stacked plot, and with its own graphical parameters, restyled from the
window itself; several exploded profiles can stay open side by side
for comparison; fixed an exploded profile being labelled "1" and
taking the first profile's line-intersection colours whatever profile
it showed
[20260817] GeoProfiler: readable profile axes: vertical tick labels
without the always-zero decimal and capped in number (five per profile
by default), both axes optionally labelled in km, the vertical one
optionally as a depth counting downwards, and each axis named with its
quantity and unit; the profile number moved out of the way of the
elevation labels; all of it configurable in the graphical parameters
dialog and saved with the styles; fixed the requested elevation range
not being honoured, as writing out the ticks widened the axis to span
them
[20260818] fixed the reading of degenerate geometries, where a single
defective feature discarded the whole source layer: features with null
or empty geometries, and parts with too few points, are now skipped
and reported in the "qgSurf" log panel, in line and polygon
intersections, point/attitude/focal mechanism projections, plane
distances and best-fit plane; polygon intersections now keep the line
parts of results that are not lines only, as produced by a profile
touching a polygon; profiles defined from a line layer now read
single-part geometries as well, and no longer require multipart ones
[20260818] help: the GeoProfiler help is aligned to the current
interface (numbered command tree, focal mechanism projection with its
beachball styles, vertical values read as depths, single profile
exploded into its own window, axis units and names, polygon categories
taken from the layer symbology, unreadable features skipped and
logged) and illustrated again, with the figures to retake marked "TO
BE UPDATED" and the missing ones marked "TO INSERT"; same marking in
the stereonet help, whose interface, style and plot figures predate
the 4.3.0 additions its text already describes; note on skipped
records added to the best-fit plane and plane distances helps
[20260819] GeoProfiler: the profile number is now written inside the
top left corner of its plot box, clear of the elevation tick labels it
used to sit against, on a light patch that keeps it legible where the
topography reaches the corner; the elevation axis name moved closer to
the box, the room kept for the profile number no longer being needed
[20260819] GeoProfiler: generating a 3D profile without having defined
the output storage is now refused with an explanatory message, instead
of being reported as successful while nothing was written; a
generation whose lines cannot all be written to the storage layer now
reports what was written, instead of confirming success and confining
the reason to the "qgSurf" log panel
[20260819] GeoProfiler: the commands defining the profile storage now
say what went wrong: giving a new 3D line layer the name of one
already in the geopackage reported only "Error with adding vector
layer", and now names the conflict and points to "Append to existing
3D line layer in geopackage"; appending to a layer that does not
exist, or that does not hold 3D lines, is refused when the layer is
chosen instead of failing at write time, once the profile has been
computed; creating a new geopackage over an existing file, which
recreated it from scratch and destroyed every layer it held while
reporting success, now asks for confirmation first
[20260819] GeoProfiler: fixed focal mechanism and attitude projections
keeping one record per label: the projection stores one solution per
record key, and those two used the label alone as the key, so all the
records sharing a label value collapsed into the nearest one to the
profile - a layer whose label field is not unique showed a single
beachball, or a single attitude, per profile. Records are now keyed by
feature id as the point projections already were, and still labelled
as before; the exported "src_fid" of projected attitudes and focal
mechanisms, until now always empty, carries the source feature id
[20260819] GeoProfiler: the beachball outline width is now a style
setting, next to the outline colour, and its default drops from the 2
points obspy draws to 0.5: at the size beachballs have on a section, a
2 point outline blotted out the quadrant boundaries it was drawing
[20260819] help: the stereonet help is fully illustrated as well - the
interface, layer input, text input, plot style and plot figures are
retaken, and the two figures its text described without showing are
there: the P-T axes plot and the canvas-linked floating window with
its depth/Z histogram
[20260819] Stereoplot: fixed the crash on plotting after a change of
project ("wrapped C/C++ object of type QgsVectorLayer has been
deleted"): the input layer defined from the previous project was kept
and used although QGIS had destroyed it. The input is now checked
before every use - plot, redraw on selection change, depth histogram,
canvas-rectangle-linked replot - and a source whose layer is gone is
dropped and reported, asking for the input to be defined again
[20260819] help: the GeoProfiler help is fully illustrated - every
figure now shows the current interface or the current plot, the "TO BE
UPDATED" and "TO INSERT" markers are gone along with the legend box
that explained them, and the nineteen figures are numbered without
gaps; removed help_0.2.html, the illustrated guide the current help
replaced, which no code opened and whose captions described
screenshots since retaken under the same names
[20260819] help: the GeoProfiler quickstart no longer skips the
definition of the output geopackage and 3D line layer, which is
mandatory and comes first, and states that a topographic profile one
already has is used as it is, entering the workflow at "1 - Choose 3D
topographic profile"; quickstart, workflow diagram and section
numbering follow the numbered command tree
4.3.1: [20260803] fixed security issues flagged by the QGIS plugin
repository scanner (Bandit): replaced runtime assert statements with
explicit exceptions and silent except/pass blocks with logged
exceptions, in qgSurf's own code and in the bundled apsg/geogst/affine
libraries
4.3.0: [20260713] fixed a crash in the Plane Distances tool (DEM grid
CRS parameter)
[20260726] GeoProfiler: removed the separate "Create geoprofile" step
(each stage now computes immediately on confirmation); sped up
line/polygon intersection and point/attitude projection (up to ~240x
faster); fixed a point-projection crash and a topographic-profile
calculation bug; added configurable profile sampling distance; various
UI/compatibility fixes
[20260802] Stereoplot: added P-T axes and tangent lineation (Hoeppner)
diagrams with dedicated styles; added live canvas-rectangle-linked
filtering with a paired floating window showing the live stereoplot
and a vertical depth/Z histogram (local vs. total distribution); main
stereoplot now follows the layer's QGIS selection; fixed
invisible/missing direction arrows (tangent lineation, faults) and a
division-by-zero for near-vertical slickenlines; invalid records are
now skipped and reported instead of raising; GeoProfiler: default
export database format changed to SQLite
