* Drop unused MVT layer mrr:appl_dl.Guilhem Moulin12 days1

* MVT: Lower max-zoom to 7 (8m/px) from 9 (2m/px).Guilhem Moulin2025-05-211
| | | | | | | | | | | | | | | | | The webmap currently doesn't go beyond zoom level 7 (8m/px) so it makes little sense to create tiles for higher zoom levels. It speeds things up and saves CPU resources and disk space, too. For group ‘ren’ on the desktop (GPKG destination dataset), before (max-zoom=9): INFO: Exported 4488 features to 4 MVT layers in 00:06:02.926 INFO: Tile count: 75972 [min=33 B, max=128.16 kiB, sum=15.10 MiB, avg=208 B] vs. after (max-zoom=7): INFO: Exported 4488 features to 4 MVT layers in 00:00:25.548 INFO: Tile count: 5031 [min=35 B, max=128.16 kiB, sum=4.80 MiB, avg=0.98 kiB]

* Update Mineralrättigheter import logic.Guilhem Moulin2025-04-281
| | | | | | | | | | | | | | | | | | | | Thanks to EU Directive 2019/1024 of the European Parliament and of the Council of 20 June 2019 on open data and the re-use of public sector information, and the Commission Implementing Regulation (EU) 2023/138 of 21 December 2022, the mineral register is now available under the terms of the CC0 1.0 Universal licence, see https://www.sgu.se/produkter-och-tjanster/geologiska-data/malmer-och-mineral--geologiska-data/mineralrattigheter-och-prospektering/ Given we no longer need to parse SVG images from the webmap, we drop webmap-download-mrr.py and add layers for expired and forbidden permits (ut_metaller_industrimineral_forfallna, ut_olja_gas_diamant_forfallna, bearbetningskoncessioner_forfallna, ut_metaller_industrimineral_forbud, ut_diamant_forbud) as well as markanvisningar_bk_ansokta. Unfortunately the GeoPackage file doesn't include peat concessions, so we drop them from config.yml for now. Should they be of interest we can always restore webmap-download-mrr.py and/or order the register from Bergsstaten, cf. https://resource.sgu.se/bergsstaten/exporter-ur-mrr-info.pdf .
* Change layer cache logic to target destination layers rather than sources.Guilhem Moulin2025-04-241
| | | | | | | | | | | | | | | | | | | | In a future commit we'll fingerprint layers to detect changes. Comparing modification times is not enough since some sources (for instance Naturvårdsverket's SCI_Rikstackande) are updated on the server even though no objects are being added; the source layer remains unchanged but the file differs because of OBJECTID changes we are not interested in. Rather than using another cache layer/table for fingerprints, we cache destination layernames rather than triplets (source_path, archive_member, layername), along with the time at which the import was started rather than source_path's mtime. There is indeed no value in having exact source_path's mtime in the cache. What we need is simply a way to detect whether source paths have been updated in a subsequent run. Thanks to the shared locks the ctime of any updated source path will be at least the time when the locks are released, thereby exceeding the last_updated value.
* Skogsstyrelsen: Relax some constraints on the schema to reflect current GPKG ↵Guilhem Moulin2025-04-231

* webmap-import: Add a cache layer and store the source file's last ↵Guilhem Moulin2025-04-231
| | | | | | | | | | | | | | | | | | | | | | | | modification time. That way we can avoid the expensive unpack+import when the source file(s) have not been updated since the last run. The check can be bypassed with a new flag `--force`. We use a sequence for the FID:s (primary key) and a UNIQUE constraint on triplets (source_path, archive_member, layername) as GDAL doesn't support multicolumns primary keys. To avoid races between the stat(2) calls, gdal.OpenEx() and updates via `webmap-download` runs we place a shared lock on the downloaded files. One could resort to some tricks to eliminate the race between the first two, but there is also some value in having consistency during the entire execution of the script (a single source file can be used by multiple layers for instance, and it makes sense to use the very same file for all layers in that case). We also intersperse dso.FlushCache() calls between _importSource() calls in order to force the PG driver to call EndCopy() to detect errors and trigger a rollback when _importSource() fails.
* Factor sources in config.yml.Guilhem Moulin2025-04-191
| | | | | | | | | This avoid duplications when the same source file is used multiple times (either by the same layer or by multiple layers). This change breaks webmap-import, but that one will be refactored shortly. It also breaks webmap-import-mrr.py, which is no longer used since mineralrattigheter.zip can be downloaded from SGU's site directly.
* mrr:markanvisningar: Make DecisionDate non-nullable.Guilhem Moulin2025-03-171
| | | | It appears it is no longer stripped in Bergsstaten's mineralregister.
* Relax some UNIQUE constraint on the MRR layer's DiaryNR column.Guilhem Moulin2024-10-291
| | | | | | | Apparently there are duplicates for dnr BS 22-28-2000 (bearbetningskoncessioner_beviljade) and BS 23-126-2007, BS 23-116-2005, BS 23-226-1930, BS 23-149-1960, BS 23-7-2000, and BS 23-105-2010 (markanvisningar_bk_beviljade).

* nva:Skogsstyrelsen: Remove NOT NULL constraint on the DatAvtal column.Guilhem Moulin2024-10-271
| | | | | | As of today SK 117-2024 has not contract date set, so the constraint fails during import. https://www.skogsstyrelsen.se/skogens-parlor/NVAvtal/?objektid=4020527
* Add comments and value substitution to some Riksintresse layers.Guilhem Moulin2024-10-201

* Add layer with noteworthy dams.Guilhem Moulin2024-10-191
| | | | | | | | Unfortunately the dam register is way too noisy Unfortunately it looks like there is no way to download a pre-curated dam registry with only noteworthy dams used for production (SvK's dammar_pf.shp comes close but still misses some), so we manually remove the ones which are more than 2km from a production site or a power station.

| | | | | | | Cf. https://skyddadnatur.naturvardsverket.se/ . We exclude Nationalstadspark (MB 4 kap 7§) since the only entry is in Stockholm (Kungliga nationalstadsparken, Ulriksdal-Haga-Brunnsviken-Djurgården) outside our extent.

* Skogsstyrelsen: Fetch Shapefiles rather than GeoPackage files.Guilhem Moulin2024-09-191
| | | | | | | | | | | | | | | | | The former have been deprecated per following note on https://www.skogsstyrelsen.se/sjalvservice/karttjanster/geodatatjanster/nerladdning-av-geodata/ Påminnelse om vektordata ------------------------ Från och med 1 mars finns vektordata i GeoPackage-format. Shape-filerna tas bort 16 september. För de flesta datamängder kommer vi att ta bort de länsvisa lagren och bara ha rikstäckande lager. These GeoPackage layers have geometry type POLYGON but appear to contain MULTIPOLYGONs as well, so fortunately there is no data loss due to geometry splitting.

* Conditionally use GetTZFlag()/SetTZFlag() depending on the GDAL version.Guilhem Moulin2024-06-201
| | | | | | | | | OGRFieldDefn: add GetComment() / SetComment() methods were added in OGR 3.8.0, cf. https://github.com/OSGeo/gdal/blob/master/NEWS.md#core-3 . Don't comment out TZ on field definitions. Instead we check the GDAL/OGR version and ignore TZ on field definitions if the OGR version is too old.

* Add logic for field regex substitution.Guilhem Moulin2024-06-191
| | | | | | | | | This is useful to replace a YYYYMMDD formatted date with YYYY-MM-DD. The target field can then be set to not-nullable and its type set to Date, as the OGR_F_SetField*() with take care of the conversion. We could also do that via an SQL query, but in our case the sources are not proper RDBMS so SQL is emulated anyway.
* sks:UtfordAvverk: Add NOT NULL constraint on AnmaldHa column.Guilhem Moulin2024-06-191
| | | | | There are a couple (15) of NULL AnmaldHa's, all from Sep 1, 2005 in Borås, so we don't care about these.
* Add logic to replace field value literals.Guilhem Moulin2024-06-191
| | | | And set them to NULL.

* sks:UtfordAvverk: Add UNIQUE constraint on OBJECTID.Guilhem Moulin2024-06-121
| | | | | | Not sure why I thought there was duplicates but I must have done something wrong as there are none in the 667034+223463+214082+ 72656 = 1177234 features found after removing the spatial filter.

* Fix extent logic when the SRS of the output layer is not the destination SRS.Guilhem Moulin2024-06-111
| | | | | | The extent is expressed in config['SRS'] in traditional GIS order (easting/northing ordered: minX, minY, maxX, maxY), but the destination layers might be pre-existing and use other SRS:es or mapping strategy.
* Add TZFlag support (for GDAl ≥3.8).Guilhem Moulin2024-06-101
| | | | (Commented out in config.yml for now since Bookworm has only v3.6.)
* config.yml: Set layer creation option FID64=YES.Guilhem Moulin2024-06-101
| | | | | | We're TRUNCATE'ing the output layers (tables) at every run and aren't reseting the sequences so they would soon overflow 32-bits FIDs ("sks:UtfordAvverk" has almost 300k features within the extent…).
* Add `webmap-import` script to import source layers.Guilhem Moulin2024-06-101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is still a few things to do (such as reprojection and geometry changes) but it's mostly working. We roll out our own ogr2ogr/GDALVectorTranslate()-like function version because GDALVectorTranslate() insists in calling StartTransaction() https://github.com/OSGeo/gdal/issues/3403 while we want a single transaction for the entire desination layer, including truncation, source imports, and metadata changes. Surprisingly our version is not much slower than the C++ one. Importing the 157446 (of 667034) features from sksUtfordAvverk-2000-2015.shp takes 14.3s while ogr2ogr -f PostgreSQL \ -doo ACTIVE_SCHEMA=postgis \ --config PG_USE_COPY YES \ --config OGR_TRUNCATE YES \ -append \ -fieldmap "0,-1,-1,-1,-1,1,2,3,4,5,6,7,8,9,10,11,12,13" \ -nlt MULTIPOLYGON -nlt PROMOTE_TO_MULTI \ -gt unlimited \ -spat 110720 6927136 1159296 7975712 \ -nln "sks:UtfordAvverk" \ PG:"dbname='webmap' user='webmap_import'" \ /tmp/x/sksUtfordAvverk-2000-2015.shp \ sksUtfordAvverk-2000-2015 takes 14s. Merely opening /tmp/x/sksUtfordAvverk-2000-2015.shp and looping through its (extent-filtered) features results in a runtime of 4.3s.
* config.yml: Allow configuration setting at the layer root.Guilhem Moulin2024-06-091
| | | | | We'll need that for layer creation (description, fields, creation options, etc.).
* Add layer definitions for Mineralrättigheter.Guilhem Moulin2024-06-031
| | | | | | | | | | | | | | | | | | Unfortunately SGU/Bergsstaten doesn't offer layer files to download, but it has an online webmap (WMS) at https://apps.sgu.se/kartvisare/kartvisare-mineralrattigheter.html so we add a dedicated module to probe and fetch features from it. Double checked that the resulting combination of GeoJSON files does not result in data loss compared to the previous (private) script: sort_features() { jq -S '.features |= sort_by(.properties.Name, .properties.Layer, .properties.Area)' } diff -u --color=auto \ <(ogr2ogr -f GeoJSON -lco COORDINATE_PRECISION=2 /vsistdout/ $dir/Mineralrättigheter.gpkg \ SE.GOV.SGU.MRR.BEARBETNINGSKONCESSIONER_APPLIED_VY | jq '.name = "MRR:" + .name' | sort_features) \ <(ogr2ogr -f GeoJSON -lco COORDINATE_PRECISION=2 -nlt MULTIPOLYGON -nlt PROMOTE_TO_MULTI \ /vsistdout/ mrr/bearbetningskoncessioner_applied.geojson | sort_features) (and similar for other layers).
