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.
