* 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
