Excel export (from TWG feedback)
- src/analysis/xlsx.js: a dependency-free XLSX writer — an .xlsx is a ZIP of
XML, so this packs the required parts with a small stored-ZIP writer. Avoids
SheetJS (stale npm package with advisories) and ExcelJS (heavy for an
offline-first field app), and does not rely on the JSZip that only reaches us
transitively via shp-write. Lazy-loaded as a ~5.6 kB chunk.
- After a zonal run the Analysis panel offers "Export table (Excel)", writing a
two-sheet workbook: Results (figures as real numbers) and Parameters (zone
and input layers with feature counts, the "Apply to" scope, membership rule,
statistics, numeric field and export time) — so a table can be verified or
reproduced later rather than being an unattributed set of numbers.
The button is hidden for overlay runs and cleared when the mode changes.
- Verified against two independent readers: openpyxl loads it with zero
warnings and correct numeric types, and LibreOffice Calc opens it as a
spreadsheet. Also exercised end-to-end through the real zonal pipeline.
COG raster entry point
- Add External Layer gains a COG type alongside WMS/WFS/XYZ, with a URL
pre-flight check that distinguishes a web page, a 404, a CORS block and a
server without byte-range support — geotiff.js otherwise reports these only
as an opaque "AggregateError: Request failed".
Digital Earth Africa ETL
- etl/deafrica_dem_to_minio.py exports a DE Africa DEM for a district as a COG
and uploads it to the LUSPA MinIO bucket raster-objects, then verifies the
object is anonymously readable and range-capable. Credentials come from the
environment; the existing PHP integration hardcodes them and an earlier key
pair reached Gitea. NOTE: not yet run against the Sandbox — start with
--list-products to confirm the DEM product name.
Documents
- Concept note: Digital Earth Africa added as a raster source (§6.3), separating
the live WMS route from the batch Sandbox export; corrected the in-house
contour table's provenance to OpenTopography (gdal_contour over an SRTM 30 m /
Copernicus 30 m DEM), and added the ToR §2.4.2 / FS §2 alignment chapter.
- TWG presentation, architecture and two integration workflow charts (SVG
sources kept in the repo so they stay editable), and a user guide for the
Analyse tools.
Service worker v13 -> v14. .gitignore: exclude Python bytecode from etl/.

Stage 1 of the GIS Analytical Tools concept — client-side spatial analysis:
- src/analysis/overlay.js: vector overlays (intersect / clip / difference /
union-dissolve) on Turf.js, reprojecting to WGS84 and merging attributes
(intersect keeps both layers', clip keeps only A's).
- src/analysis/zonal.js: vector-in-vector zonal statistics — count / sum /
mean / min / max / total area per zone, with centroid-in-zone (default) or
any-overlap membership.
- Bounding-box pre-filtering in both: only genuinely overlapping pairs reach
the expensive geometry test. 43 zones x 25,004 parcels now completes in
~106 ms; previously it was refused as too large.
- src/analysis-modal.js + markup: Analysis panel with "Apply to" scoping —
whole layer, current map view, selected features, or the catch of a drawn
Circle/Area. Reached from a new "Analyse" dock button.
- MapView.addCOGLayer() for Cloud-Optimized GeoTIFF display (WebGLTile +
GeoTIFF source, imported lazily); listVectorLayers(); getSelectedFeatures().
- Circle/Area analysis popup: one "Export" button (PDF folded into the export
modal as a fourth format, field-rename table hidden for it) plus an
"Analyse" button that opens the panel pre-scoped to the intersecting
features.
- vite.config.js: code-split turf, geotiff and pako so the eager bundle is
unchanged (~283 kB). Giving pako its own chunk also fixes a circular chunk
between jspdf and geotiff, which share it via fast-png.
Drawing-tool fixes carried in the same working tree:
- Delete/Backspace key deletes the selection via the EditBar's Delete
interaction (same undoable block as the button).
- Multi-select: shift-click toggles, Ctrl/Cmd-drag box-selects; helper layers
(vertex overlay, GPS) excluded.
- Undo: split/merge/divide wrapped in undo blocks so one press reverses the
whole operation; vertex-overlay churn no longer pollutes the undo stack;
sources are re-scanned and the stack cleared when edit mode is entered, so
deletes on sub-grouped layers are undoable. NOTE: the undo behaviour is not
yet confirmed on-device.
- ol-ext TouchCursor gated to touch-only devices, so hybrid touchscreen
laptops keep the normal cursor.
Service worker v12 -> v13.

The /?logout=1 endpoint destroyed only the PWA's own PHP session and then
redirected to the bare landing page — which has no session and immediately
blocks access, so the user was never actually logged out of SSO.
- public/index.php: after session_destroy(), redirect to
https://lupmis4luspa.org/user-logout (the portal's full SSO logout) instead
of the landing page. Crucially, no longer clear sso_auth_token here —
/user-logout needs that cookie to identify which SSO session to terminate
(and it clears the cookie itself). The production access-guard bounce to the
landing page is unchanged.
- main.js: drop the now-redundant best-effort client call to /sso/logout; the
server redirect chain (/?logout=1 → /user-logout) owns the SSO logout. Offline
guard and district-cache wipe unchanged.
- sw.js: update the v12 changelog note (still v12; not yet deployed).

Session / district correctness
- public/index.php: add a /?logout=1 endpoint that destroys the PWA's own PHP
session (session_destroy + expire PHPSESSID + clear sso_auth_token, then
redirect to the SSO portal). Logout previously cleared only the SSO cookie,
leaving the PHPSESSID session — and its frozen district_id — intact, which is
why a reassigned user kept loading the old district across logout/login.
- SSO token is validated once per session, at login (unchanged first-login
logic). A district transfer is now picked up on the next logout→login, which
is correct precisely because logout finally tears the session down. No
periodic SSO polling.
- main.js: the menu Logout button routes through /?logout=1 and wipes
district-scoped local caches first. Logout is blocked while offline — a
session can only be created online, so an offline logout would strand the
user with no way back in (and would not actually reach the server).
- main.js: enforceDistrictConsistency() clears district-scoped caches when the
session district changes between loads; the district boundary is cached under
a per-district key (district_boundary_<id>) so one district's geometry can
never be served for another.
GPS coordinate format
- New "GPS Coordinate Format" setting (Lat/Lon · UTM · Both) in the Settings
panel; the navbar read-out renders the chosen format and repaints the current
fix immediately on change. Self-contained WGS84→UTM converter in
geo-utils.js, verified against an independent Redfearn-series implementation.
ol-ext touch cursor
- MapView gates the TouchCursor to genuine touch-only devices via matchMedia
(any-pointer: fine / any-hover: hover); hybrid touchscreen laptops keep the
normal cursor. Reactive to pointer-capability changes.
- Service worker v11 → v12 (new shell). docs/SSO_Session_Refresh_Proposal.md
documents the implemented approach.

Evicts the stale shell + module caches at the next deploy so existing
clients pick up the permit-iframe auth-required card, the new
X-Frame-Options strip, and the import-UX refinements (parse spinner,
client_uuid tagging, geometry/delete persistence, sample values +
Unicode-bold field names in the mapping dropdown).

Permit-iframe hardening:
- public/embed.php — replace the 302 redirect on unauthenticated visits
with an in-iframe HTML "Sign in to view the map" card (HTTP 401)
whose primary button uses target="_top" to break the iframe and send
the parent window to the SSO portal. The 302 was broken UX inside an
iframe because the LUSPA portal refuses to be framed.
- public/embed.php + public/.htaccess — strip X-Frame-Options at the
embed endpoint (defence in depth). Apache's <Files "embed.php">
Header always unset X-Frame-Options + PHP's header_remove() both
ensure the only iframe-policy header on the response is our CSP
frame-ancestors (which already allows the permits subdomain). Fixes
Safari's "Refused to display ... because it set 'X-Frame-Options'
to 'SAMEORIGIN'" when the container's reverse proxy injects it.
Import UX refinements:
- Spinner overlay (index.html #import-spinner-overlay + main.js
showImportSpinner/hideImportSpinner) shown during the file-drop →
mapping-modal gap. Wired at the top of each handle*Import and at
every error / early-return path; hidden by stageImport() just before
openImportMappingModal() so it spans both the JS parse and the
SQLocal staging insert.
- Per-feature client_uuid tagging — each imported OL feature now
carries _externalImportId + _clientUuid set in stageImport(). These
tags are the link that lets later edits find the matching staging
row, and they are passed through to addExternalImportFeatures.
- Geometry-edit persistence — new public callback registry
MapView.onFeatureModified(cb) fired from a modifyend listener on
_modifyInteraction. main.js handler writes the new WKT (EPSG:4326)
back to external_import_features.geometry_wkt via new helper
updateExternalImportFeatureGeometry(clientUuid, wkt). Non-imported
features carry no tags, so the handler is a no-op for them.
- Delete persistence — removefeature listener on each imported layer's
source. New helper deleteExternalImportFeature(clientUuid) runs an
atomic DELETE + decrement of external_imports.feature_count and
broadcasts the changes so the LayerSwitcher badge can recount.
- Field-mapping dropdown — sample values + bold field names.
New helpers sampleSourceValues(fc) in import-detect.js (picks first
non-empty value per attribute, JSON-stringifies objects, collapses
whitespace, truncates to 35 chars) and toBoldUnicode(s) in
import-modal.js (ASCII letters/digits → Mathematical Alphanumeric
Symbols block). Options now read as "𝐮𝐩𝐧 — [12345-6789]";
HTML/CSS bold doesn't render inside <option> elements, so Unicode
bold codepoints are the cross-browser way.
Workshop deliverables:
- LUPMIS2_Improvements_Mar_to_Jun_2026.docx — handout mirroring the
slide deck one-to-one (160 paragraphs, branded styling).
- LUPMIS2_Workshop_Mar_to_Jun_2026.pptx — 16-slide pptxgenjs deck
(16:9 widescreen, brand palette, hero + content + closing masters,
embedded staged-upload diagram on slide 9).
- LUPMIS2_Staged_Upload_Flow.svg + .png — three swim-lane diagram of
the staged-upload pipeline with a dedicated "Client QA Gate"
callout. Hand-crafted SVG + 2400 px PNG.
save_gps_trail.php diagnosis (no code change, on the database team):
the reported "CORS" error is a missing endpoint — Apache returns 404
with no CORS headers and the browser surfaces it as access-control.
Once the endpoint is deployed the API server's global CORS handling
attaches the right headers and the GPS-trail sync will work without
client changes.
dist/ rebuilt.

UPN-grid layer:
- src/database.js — new upn_grid SQLocal table (id, districtid, upn_prefix,
geometry_wkt) + saveUpnGrid / getLocalUpnGrid; cache-once-per-district.
- src/remotedb.js — getUpnGrid → get_upn_grid_per_district.php.
- main.js loadUpnGrid + upnGridToGeoJSON in the Administration group, with
a zoom-aware style: white casing under a bolder violet dashed stroke
(visible against parcels) and upn_prefix labels rendered only when
resolution ≤ 7 m/px (≈ scale ≤ 1:25,000).
- main.js click handler: single click on a UPN-grid cell opens an info
popup showing the upn_prefix.
External-dataset import → staging → upload (client-side complete):
- src/database.js — external_imports + external_import_features tables,
plus createExternalImport / addExternalImportFeatures /
updateExternalImport / getExternalImport / getExternalImportFeatures /
listExternalImports / remapImportedFeatureProperties /
deleteExternalImport. Status enum: imported/mapped/other/uploading/
submitted/migrated/failed (aligned with the database team's staged-
upload model — lu_parcels_upload_tmp + supervisor review).
- src/import-detect.js — pure helpers: detectTargetType(),
autoMapFields(), applyFieldMapping(), listSourceFields() + TARGET_TYPES
/ TARGET_FIELDS registries.
- src/import-modal.js — Bootstrap mapping modal: target dropdown,
field-rename table, three actions (Cancel / Save / Save + Upload now).
- main.js — stageImport hooked into addImportedGeoJSON (the single
convergence point for shp/GeoJSON/KML drops); handleImportModalResult
applies the mapping in one transaction; runUpload builds the real
payload (district_id + api_token from remotePost, user_id_upload from
SSO session, per-feature client_uuid/geom/props) and currently logs +
toasts — the upload_<target>.php endpoints are not yet live.
- index.html — #importMappingModal markup.
- MapView._decorateLayerListItem — import-state chip (Upload N /
spinner / ✓ submitted / ✓ live / N errors) dispatching
lupmis:import-chip-click; src/styles/layerswitcher.css — chip variants.
GIS export from Area / Circle Analysis popups:
- MapView._showAnalysisPopup now accepts an exportContext (clipGeometry +
parcelFeatures + zoneFeatures + otherByLayer) and renders an "Export
GIS" button next to "Export PDF". Click dispatches lupmis:export-gis.
- index.html — #exportGisModal markup.
- src/export-gis-modal.js — Bootstrap modal: format toggle (GeoJSON
default / Shapefile / KML), filename, field-rename table with SHP
10-char DBF warning.
- src/gis-export.js — writers: GeoJSON via Blob, KML via OL KMLFormat,
Shapefile via shp-write (with DBF-safe name sanitiser).
- Adds shp-write@0.3.2 dependency.
MapView style options:
- addGeoJSONLayer now accepts strokeDash for line-dash patterns (used by
the UPN-grid layer and available for any future contextual overlay).
Service Worker v9 → v10 to evict the stale shell/module caches on the
next deploy.

Iframe embed for the Permitting app (LUPMIS2_Reusable_Mapping_Concept §3.2):
- public/embed.php — SSO + production gate + frame-ancestors CSP +
whitelisted URL params (mode, lon/lat/zoom, upn, basemap,
application_code); injects window.LUPMIS_SESSION + window.LUPMIS_EMBED.
- public/.htaccess — clean /embed URL (rewrite before the SPA fallback).
- src/embed-bridge.js — postMessage protocol: out ready / parcel:select /
parcel:cleared / error; in set:view / set:selected / clear:selected /
set:basemap. Visual highlight via a dedicated VectorLayer; pending-UPN
queue resolved as parcels stream in.
- main.js — reads window.LUPMIS_EMBED, gates the normal click/dblclick
handlers in permit mode, exposes parcelsLayer to module scope, makes
it visible and hands it to the bridge after loadParcels().
- index.html — CSS for body.embed-mode-permit hides navbar/dock/offcanvas
and lets the map fill the iframe.
- LUPMIS2_Permit_Map_Integration.docx — integration instructions for the
Permitting team (contract, show.blade.php changes, phasing).
Local lu_parcels structural refactor:
- src/database.js — parcels table now mirrors spatial.lu_parcels with
explicit columns (upn, style, landuse, zone_code/name, sector, block,
parcel_no, prop_no, st_name, prop_add, fac_name, min/max_height,
eff_date, lp_name, locality, mmda, last_update, remarks, geom→geometry_wkt,
created_at, updated_at, districtid) plus local-only status/fetched_at.
Drop-and-recreate migration off `upn` presence. saveParcels wraps the
~25k inserts in a transaction; numeric coercion via numOrNull.
updateParcel/insertNewParcel write individual columns.
- main.js parcelsToGeoJSON — handles GeoJSON `geom` object (API) and
`geometry_wkt` string (local cache); skips housekeeping fields.
Production access guard + no-district overlay:
- public/index.php — on *.lupmis4luspa.org, redirect to the SSO portal
if no session.
- src/remotedb.js resolveDistrictId — no silent fallback to '1' for an
authenticated user; dev mode (no session at all) keeps the fallback.
- main.js — blocking overlay if the session lacks district_id; init
aborts so no API call is made with the wrong scope.
LayerSwitcher ordering fix:
- MapView.initEditBar + MapTools — find the Overlays group by reference
/ title instead of assuming it's the last layer (the GPS layers
add-layered on top in the constructor broke that assumption).
Service Worker v8 → v9 to evict stale shell/module caches on deploy.

Major:
- GPS trail recording: reusable, dependency-free engine in src/geotracker/
(GeoTracker + geo-utils) with pluggable storage/sync adapters; LUPMIS
wiring in src/geotracker-lupmis.js. Expandable My Location control
(Locate Me + Record Trail), live navbar GPS readout, on-map trail/position
rendering, gps_trails/gps_trail_points SQLocal tables, and store-and-forward
sync via pushGpsTrail() -> save_gps_trail.php (server side documented, not
yet built).
- SSO authentication: public/index.php entry point validates the LUSPA SSO
cookie and injects window.LUPMIS_SESSION; remotedb district_id is now a
session-resolved getter. Adds public/.htaccess (DirectoryIndex).
- Account menu offcanvas (navbar burger) with sign-in/out states.
UI / fixes:
- LayerSwitcher modernisation; base-map "None" option in picker + settings.
- Mobile drawing toolbar wraps to two rows below 576px and shows only in
Draw mode; second row right-aligned and clears the Select option bar.
- Safari bottom-dock clipping fixed (app-container 100dvh -> 100svh).
- Rename public/icons -> app-icons to dodge Apache's default /icons/ alias.
- Service Worker bumped to v8 (network-first HTML, per-provider tile clear).
Docs: reusable-mapping and OSM-3D-buildings concept notes; ignore Office
lock files (~$*). Rebuilt dist/.
