0.4.1
- Needs Aether engine 0.4.3 or newer; the Map Converter's seam filter
and
fast building preparation need the converter of engine 0.5.0.
- Code hygiene for the plugins.qgis.org security scan; deprecated
supportsQt6 flag removed (QGIS 4 support comes from
qgisMaximumVersion).
0.4.0
- Map Converter: XYZ terrain downloads through one shared pool in 1°
bands with two lanes, a repair pass for failed tiles, local files
converted while the download runs; OpenFreeMap buildings fetched
beside
the terrain (building prep under a second instead of ~25 s);
background
size estimate, "Auto" resolutions (finest source + 30 m / 90 m rings),
tiles outside every layer skipped, Terrarium seam at 10°E repaired;
folder index for GeoTIFF folders, whole-run progress bar, shared
extents, add folder / all layers.
- Site Analysis and Point-to-Point: "Folder…" picks a terrain folder;
engine diagnostics go to a daily log file in the terrain cache, the
QGIS
log keeps the key lines; remembered output folders; per-band buildings
for adaptive and custom range profiles; plots drawn by the plugin.
- Data sources credited in Settings and Help (Terrarium via AWS,
OpenFreeMap); waveshed.io links work before and after the public
launch.
0.3.3
- Minor fixes. (New Icon and proper Metadata)
0.3.2
- Settings no longer shows "Installed engine: unknown" right after a
successful download when the new engine is slow to answer its first
version check; probe failures are now written to the QGIS log.
- Plugin repository tags include line of sight and viewshed.
0.3.1
- Automatic release deployment.
0.3.0
- Engine downloads are verified end to end: the release manifest must
carry a valid signature from the Waveshed release key (releases up to
engine 0.4.7 predate signing and are still accepted), and engine
archives are only accepted from releases.waveshed.io.
- Engine updates are all-or-nothing: the new engine is unpacked and
test-started next to the old one and only then swapped in. A failed or
interrupted update leaves the previous engine working; on Windows an
engine that is still running is detected and the update is refused.
- First start without an engine shows a notice with a button to
Settings.
Once per QGIS session the plugin checks for a newer engine and shows a
notice (once per release) with an "Update" button; the check can be
switched off in Settings. Settings shows the installed and the latest
engine version and has a "Check for updates" button.
- An analysis that fails because the engine is too old or missing now
offers "Update engine" / "Open Settings" right in the error message.
- macOS: engine folders chosen with Browse or Auto-detect (for example
a
browser download) are made executable and cleared of the download
quarantine, as on every plugin start; if macOS still blocks the
engine,
the error names the one Terminal command that fixes it.
- The plugin is no longer marked experimental.
- "Minimum LOS Altitude" is now "LOS Floor" everywhere in the UI. The
Processing wire value stays MIN_ALT, so saved models keep working.
- Built-in Help: a searchable Help tab (last tab of the dialog), a
"Waveshed Help" menu entry and a "?" next to the model choice. Covers
every control, terrain sources and the no-data contract, LOS Floor and
the Altitude Explorer, the Processing algorithms, earth-curvature and
ITM notes, troubleshooting and a glossary.
- Altitude Explorer: each altitude band has its own AGL/AMSL
reference,
so "100 m AGL" and "2500 m AMSL" can be shown together. "Measured
from" applies to the selected band and the next one added; sea-level
bands render on the cached terrain twin, built on first use.
- Engine failures now carry an actionable hint. An engine that rejects
90 m / 250 m ("Unsupported resolution ... Allowed: [2, 5, 10, 30]")
is an older build: update it via Settings, or pick 2/5/10/30 m.
- Requires Aether engine 0.4.3 or newer for 90 m and 250 m coverage
and
for correct ITM results with AMSL antenna heights on the GPU.
0.2.0
- Runs on QGIS 4 (Qt6/PyQt6) as well as QGIS 3.28+ (Qt5): every Qt and
QGIS enum is now spelled with its scope, QAction is imported from
whichever module the binding keeps it in, and exec_() became exec().
- Terrain tiles are pooled and reused across sites, so overlapping
runs no
longer re-download shared tiles. Existing caches are rebuilt once.
- Building tiles (OpenFreeMap) pool alongside terrain and are reused
too.
- Removed SIMPLE_LOSS as a selectable propagation model; use ITM.
Results
already computed with it still load. NOTE: the Processing "Propagation
Model" dropdown is index-based, so saved Processing models that
selected
ITM or MIN_ALT must be re-picked.
- Data-source attribution for every fetched dataset, shown in
Settings.
- Settings can clear the terrain cache and reports its size.
- Fixed: a failed building download no longer silently caches
building-free terrain under a buildings-keyed entry.
- Fixed: partial caches from an interrupted run are no longer reused
as
complete, which produced coverage with silent gaps.
0.1.0
- Initial experimental release.
