feat(STAC): search by drawn, selected or loaded shape, with a buffer - #1703
Adds searching a STAC API by a shape you build, with an optional buffer, as new optional params
on stac.search (existing ids and params are unchanged) and a Search area in the STAC Search
pane.
Search area (desktop pane). Each choice adds a part; the pane says how many of each kind, and the
area is drawn on the map while the pane is open:
Draw point / line / polygon / extent: the map's existing click-to-add, double-click-to-finish
tools (and a dragged box for the extent). The shape joins the area, not a graphics layer; Esc
or another tool stops drawing.
Selected features: the active layer's selection.
Load file…: the features of a file in any format RustGIS reads.
Current extent: the map's extent as a polygon.
Clear.
Widen points and lines by (unit): always shown, in the Distance units setting
(Meters, Feet, Kilometers or Miles).
Reading a file or merging a large selection runs on a thread of its own, with a spinner and Cancel.
Commands.
stac.search gains intersects (GeoJSON, or "selection" of layer), layer, buffer and unit. intersects replaces bbox (a notice says when both are given). The area from the
pane is sent as a GeoJSON GeometryCollection.
buffer is up to 1,000,000 metres in unit (default Meters) and is applied geodesically to
points and lines only; a polygon is not widened and a notice says so.
New stac.area command returns the merged, buffered shape (from path, a file, or a layer's
selection) without searching.
How shapes are merged and sent.
Only the highest dimension present is kept (polygons, then lines, then points); what is left
out, and any line or polygon with too few positions, is reported once per kind with a count.
Polygons are dissolved; positions are rounded to 8 decimals; a shape over 20,000 positions or off
the globe is refused.
Servers get the shape in a POST /search body; the query string is the fallback only when the
shape fits in 4000 characters. A POST search returns no next, and a notice says when more
items match than were loaded.
Static catalogs have no search, so each item's footprint is tested against the shape
(antimeridian-aware box test, then exact intersection).
A click on a repeated copy of the world is wrapped onto the globe.
Docs: "Searching by shape" in docs/user-guide/web-data.md; GEOLIBRE_PARITY.md updated.
Behaviour reference. The Kentucky STAC QGIS plugin (GPL-2.0) was followed for which features
to offer only. No code was copied or translated from it.
Not in this PR: sort and cloud-limit UI with retry order, band combinations and indices, an item
inspector, mosaic, lidar/VPC, and script export.
Testing
cargo xtask ci (fmt, clippy -D warnings, tests, layers) passed on fe4b29f1.
New tests: merge rules, rounding, degenerate parts, hostile input, antimeridian footprints, the
GET and POST requests, notices both ways (lossy input says it, clean input does not); the buffer's
units and bounds; each drawn shape's points, shapes too small to search with, wrapping, Clear,
stopping when another tool is picked, the part limit, a non-numeric buffer, and landing a
background merge with its notices.
Rendered the pane with ui_shot (screenshots below).
The wasm32 build was not run locally; it is left to CI. Load file is desktop only; in the
browser a merge runs on the one thread.
Search STAC items using map drawings, selected features, the current view, loaded files, or GeoJSON. Combine area parts and reuse generated search areas.
Add a distance buffer to points and lines; boxes and polygons are searched as drawn. Static-catalog results are filtered by their footprints.
Searches with an area use POST, with a GET fallback when possible. The app reports when area parts are omitted or results may be incomplete.
Documentation
Updated the user guide with area-search options, limits, buffering, and search behavior.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
STAC Search accepts areas from GeoJSON, selected features, drawings, the current extent, or files. The engine validates and merges geometry, applies it to API and static-catalog searches, and returns the resolved area. The UI adds area controls, buffering, and map display.
Changes: STAC Shape Search
Layer / File(s)
Summary
Parse, merge, and match search areas crates/tiles/src/stac/area.rs, crates/tiles/src/stac/catalog.rs
Area helpers parse GeoJSON, validate and merge geometry, apply dimensional precedence and coordinate rounding, and compare shapes with item footprints. Catalog filters use the shape instead of bbox when an intersects geometry is present.
Build area requests and filter catalog items crates/tiles/src/stac.rs, crates/tiles/src/cache.rs
Search accepts an intersects geometry. GET requests serialize it subject to a URL-length limit; POST helpers build JSON bodies and detect next links. Named-address POST helpers support API requests.
Resolve areas and run STAC searches crates/engine/src/cmd/stac_area.rs, crates/engine/src/cmd/stac.rs, crates/engine/src/cmd/mod.rs, crates/engine/src/tests.rs
The engine registers stac.area and resolves areas from files, selections, or GeoJSON. stac.search uses POST for area searches and falls back to GET when possible. Search results include the resolved area.
Create and submit areas in the UI crates/ui-egui/src/stacui.rs, crates/ui-egui/src/mapview.rs, crates/ui-egui/src/lib.rs
The UI supports drawn, selected, extent, and file areas. It displays areas on the map and submits area searches by POST, with GET fallback when available.

Merge Risk: Moderate · previous review d80cf
Shape-based STAC search works in the main cases. Before merge, move the combined polygon union off the UI frame, because it can freeze the desktop window. Several smaller edge cases in drawing, project switching, paged results and point searches would also be worth fixing.

If the limit is exceeded, return an error identifying the layer and limit;
otherwise preserve the existing geometry collection behavior.
Review comments at @crates/engine/src/tests.rs:
- Around line 37341-37354: Update the bad-input loop in the `stac.search` test
to verify each error reflects input validation rather than merely asserting that
an error occurred. Inspect the returned error text for the expected validation
failure, or at minimum ensure it is not a connection error; preserve the test’s
existing hostile-input cases and URL setup.
- Around line 37337-37338: Strengthen the `stac.area` test around `s.run` by
checking that the returned polygon’s bounds extend beyond the unbuffered point’s
coordinates, so the buffer is measurably nonzero and not expressed in degrees.
Also assert that the result contains no bbox-dependent fields, without changing
the existing geometry-type check.
Review comments at @crates/ui-egui/src/stacui.rs:
- Around line 1114-1128: In the `st.use_selection` buffer parsing branch, accept
and assign `p["buffer"]` only when the parsed value is finite and nonnegative;
route parse failures and invalid values through the existing error-and-return
path.
- Around line 1149-1165: Update the search request flow around
`search_post_url`, `search_body`, and `post_service` to retain the search
parameters and retry with `stac::search_url` if the POST fails and the shape is
short enough to fit in a GET request. Preserve the existing POST behavior for
other searches and report the failure if the GET fallback is not applicable or
also fails.
Review comments at @GEOLIBRE_PARITY.md:
- Line 58: Update the STAC Search entry to describe dialog support as box,
GeoJSON shape, or selected features, and clarify that file input is available
through stac.area rather than the dialog. Preserve the surrounding parity
details and avoid implying that the dialog has a file picker.

Dialog shape POST uses the internet-only agent, so a local or LAN STAC API works for GET but fails for shape searches in the dialog, while the CLI works. Confidence: high. Inline on stacui.rs:246.
A buffer near the antimeridian can produce longitudes beyond ±180, which the re-merge then refuses with a misleading error. Confidence: medium, not yet run. Inline on stac_area.rs:104.
When the union comes back empty, dissolve returns the input polygons unchanged and reports nothing. Confidence: medium. Inline on area.rs:141.
Security
None found. The POST path keeps the same address and login checks as the GET path.
Performance
The dialog's find_items merges the selection, dissolves it, and buffers it on the UI thread, with no background path or cancel. Confidence: medium-high. Inline on stacui.rs:1130.
Quality
Features with no geometry are skipped silently in from_file, selected and geometries_of_geojson. Confidence: medium. Inline on stac_area.rs:40.
names_bbox checks b(p, "view"), but view is not a parameter, so that clause is dead. Confidence: high. Not posted; this is a nit for the release quality pass.
On any POST error, search() retries as GET, which can double the wait on a timeout. Confidence: medium. Not posted; quality point.
AGENTS.md
stac.area reads a whole file on the calling thread with no background path and no doc comment saying why it must stay there. Confidence: high. Inline on stac_area.rs:40.
Panic and unsafe rules: no violations found in non-test code.
Already raised in earlier threads, not repeated (6): the clone-before-limit in selected; the weak test assertions; the NaN and negative buffer in the UI; the missing GET fallback in the dialog; the "file" wording in GEOLIBRE_PARITY.md; and the active-layer capture for non-selection searches.

Allow shape searches against user-named local STAC APIs.
On desktop, cache::post_json uses the public-only agent. A local STAC API can work with GET searches, but a shape search can fail because the POST resolver rejects its local address.
Add an async POST variant that uses download_agent for user-named addresses, and use it for the selected API. Keep the public-only boundary for document-provided addresses.

If a shape search returns a POST-method next link, parse_items discards it. The command then returns the first page with next: null and no truncation warning, even when numberMatched is present.
Preserve a separate pagination-presence signal for the warning without returning the POST link as a GET address.

The loop checks only is_err(). A case can fail for an unrelated reason, such as a connection error to url, and the test still passes. Use table-driven cases with an expected error fragment. Assert on that fragment for each case.

stac.search takes optional intersects (GeoJSON, or "selection") and buffer.
A shape replaces bbox and is sent as a POST body, falling back to GET when
short. Merging keeps the highest dimension and reports what it left out.
Static catalogs filter by footprint. New stac.area builds the shape from a
file or a layer's selection. The STAC dialog can search near the selected
features.
Behaviour followed from the author's Kentucky STAC QGIS plugin (GPL-2.0);

Disable Find Items while the search area is loading.
If a file or selection merge is pending, Find Items can search the previous parts or the map extent instead. The completed geometry does not update that search.

- Around line 40659-40750: Extend the
`stac_search_by_shape_says_what_it_leaves_out` test to cover lossy input to
`stac.area`: use a selected layer containing a point and a polygon, then assert
the call emits the lower-dimension notice and returns `ignored` as 1. Keep the
existing clean-input assertion intact.
- Around line 40711-40712: Update the stac.search test around the run call to
make a layer other than pts active, and give pts a distinct selection; keep the
explicit "layer": "pts" argument and assert that the result uses pts’s
selection.
Review comments at @GEOLIBRE_PARITY.md:
- Line 57: Update the STAC Search entry to clarify that the buffer widens points
and lines only; do not imply that it applies to boxes or polygons.

Resolve combined polygon areas off the UI frame.
If the user adds two complex polygon parts, this call merges and dissolves both before it starts the request. The background load only merges each file or selection separately. A polygon union near the 20,000-position limit can therefore stall the desktop frame when the user clicks Find Items. Move the combined resolution to background work and keep Find Items pending until it completes. (raw.githubusercontent.com)

Update the Find Items flow around search_with_area so combined polygon resolution runs in background work rather than blocking the UI frame. Keep Find Items pending until resolution completes, then continue the search request using the resolved area.

Keep point searches usable with Add as Time Series.
An unbuffered point has a zero-width and zero-height asked_area. cube_params later sends that extent as bbox, but stac_cube requires west < east and south < north. The time-series action fails even when the search found suitable items. For a degenerate search extent, use the found items’ bounds or expand the extent before constructing the cube request.

Review comment at @crates/ui-egui/src/stacui.rs at line 1485:
Update the search extent selection around `search.as_ref()` so a zero-width or zero-height point-search bbox is not passed unchanged to the time-series cube request. For degenerate extents, use the found items’ bounds or the existing extent-expansion mechanism, ensuring the resulting bbox has west less than east and south less than north; preserve the current bbox/intersects selection for non-degenerate searches.

Review comments at @crates/ui-egui/src/stacui.rs:
- Line 1349: Update the drawing-state check around app.session.tool so it
validates the active Graphic shape against drawing, rather than checking only
for the Tool::Graphic variant; clear or stop the stale drawing state when they
differ so take_drawn does not route a normal point into the search area.
- Line 399: Update the Asked::Search response handling to use stac::has_next
when a POST response has a next link but no matched count, so the pane displays
the existing narrow-search message instead of “Showing {n} items.” Preserve the
current item and matched-count parsing behavior for other responses.
- Around line 1379-1380: Update the `Some(a), Some(b)` extent-construction
branch before calling `rectangle` to detect when the longitude pair crosses the
antimeridian; split the extent at the dateline or reject it with an explanation
before adding the part. Preserve the existing min/max rectangle behavior for
non-crossing extents so a 179° to −179° span never becomes a near-global
rectangle.
- Around line 1338-1339: Update add_selected and poll_loading to capture the
project and map identity when the selection merge starts, then verify both still
match before applying the result through land; discard stale results after
either identity changes.
Review comments at @docs/user-guide/web-data.md:
- Around line 90-91: Update the static catalog description in the user guide to
clarify that results include items whose footprint meets the shape as well as
items without a usable footprint; advise users to check items without a usable
footprint rather than treating them as verified spatial matches.

Summary
Adds searching a STAC API by a shape you build, with an optional buffer, as new optional params
on
stac.search(existing ids and params are unchanged) and a Search area in the STAC Searchpane.
Search area (desktop pane). Each choice adds a part; the pane says how many of each kind, and the
area is drawn on the map while the pane is open:
tools (and a dragged box for the extent). The shape joins the area, not a graphics layer; Esc
or another tool stops drawing.
(Meters, Feet, Kilometers or Miles).
Reading a file or merging a large selection runs on a thread of its own, with a spinner and Cancel.
