* 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.
* Add layer definitions for Vindbrukskollen layers.Guilhem Moulin2024-06-221

* 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.
* Conditionally use GetComment()/SetComment() depending on the GDAL version.Guilhem Moulin2024-06-201
| | | | | | | | | OGRFieldDefn: add GetComment() / SetComment() methods were added in OGR 3.7.0, cf. https://github.com/OSGeo/gdal/blob/master/NEWS.md#core-5 . Don't comment out comments on field definitions. Instead we check the GDAL/OGR version and ignore comments on field definitions if the OGR version is too old.
* config.yml: Start comments with an uppercase.Guilhem Moulin2024-06-201

* 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.
* webmap-import: Rename ‘fields’ list/dict to ‘field-map’.Guilhem Moulin2024-06-161
|
* Add schema for MRR layers.Guilhem Moulin2024-06-121
|
* 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.
* config.yml: Add field comments.Guilhem Moulin2024-06-111
| | | | (Commented out for now since Bookworm has only GDAL v3.6.)
* config.yml: Refine destination schema.Guilhem Moulin2024-06-111
| | | | | | | Tighten column width and replace fixed-width numerics with single precisions floats. Also, align column names with the documented ones.
* config.yml: Improve description.Guilhem Moulin2024-06-111
|
* config.yml: Preserve layer name from administrativindelning.gpkg.Guilhem Moulin2024-06-111
|
* 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).
* Rename script into module and run module.download().Guilhem Moulin2024-06-021
| | | | | Instead of using a dedicated executable. There is too much code duplicate otherwise.
* Add layer definitions from Sametinget and Vindbrukskollen.Guilhem Moulin2024-06-011

* Add `webmap-download` script.Guilhem Moulin2024-06-011
