* 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.

* webmap-import: Improve variable name.Guilhem Moulin2024-06-191

* 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.

* Add logic to replace field value literals.Guilhem Moulin2024-06-191
| | | | And set them to NULL.
* webmap-import: Use the identity mapping if no ‘field-map’ is specified.Guilhem Moulin2024-06-161
| | | | | The previous default map was [-1] * n i.e., all source fields were ignored.
* webmap-import: Rename ‘fields’ list/dict to ‘field-map’.Guilhem Moulin2024-06-161

* Don't warn about unexisting fields for empty GeoJSON sources.Guilhem Moulin2024-06-121
|
* Use systemd.journal to log to journald when sarted via .service files.Guilhem Moulin2024-06-111
| | | | This enables proper filtering by level etc. (incl. journald coloring).
* config.yml: Add field comments.Guilhem Moulin2024-06-111
| | | | (Commented out for now since Bookworm has only GDAL v3.6.)
* webmap-import: Add error-checking for CreateFeature().Guilhem Moulin2024-06-111
| | | | | | Despite using gdal.UseExceptions() a failed call doesn't raise an exception, so we need to check the return value to avoid missing features.
* webmap-import: Improve INFO message.Guilhem Moulin2024-06-111
|
* Improve comments.Guilhem Moulin2024-06-111
|
* webmap-import: Add geometry conversion support.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.
* WordingGuilhem Moulin2024-06-111
|
* Add support for reprojection into the destination SRS.Guilhem Moulin2024-06-111
| | | | | | The configured extent is always expressed in the destination SRS, so it needs to be transformed into the source SRS. Like apps/ogr2ogr_lib.cpp, we segmentize it to make sure it is sufficiently densified.
* Add TZFlag support (for GDAl ≥3.8).Guilhem Moulin2024-06-101
| | | | (Commented out in config.yml for now since Bookworm has only v3.6.)
* webmap-import: Don't try to set description if it is unset in config.yml.Guilhem Moulin2024-06-101
|
* webmap-import: Rename getFieldTypeCode() to parseFieldType().Guilhem Moulin2024-06-101
| | | | And getFieldSubTypeCode() to parseSubFieldType().
* 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.
