Even, thank you for your quick answer. Just one quick question - is it possible to do what you suggest with vector tiles in a user-defined tiling scheme (CRS which I use is EPSG:5514)? Thanks! Linda -- Původní e-mail -- Od: Even Rouault Komu: Linda Kladivová , gdal-dev@

Actually you may need to actually use -clipdst to avoid generating partial tiles. Le 31/01/2023 à 20:02, Even Rouault a écrit : Linda, you'll have to do a bit of manual work. You may use the -spat option of ogr2ogr with bounds that exactly match the bounds of affected MVT tiles in EPSG:3857,

Linda, you'll have to do a bit of manual work. You may use the -spat option of ogr2ogr with bounds that exactly match the bounds of affected MVT tiles in EPSG:3857, and then move the generated .pbf tiles back to the full dataset. Even Le 31/01/2023 à 19:42, Linda Kladivová a écrit : Hello

Hello guys, it is possible to update the MVT tileset using ogr2ogr? My data often changes and I would need to reseed tiles in the specific area given by MBR. I am looking for similar functionality as GeoServer provides (https://docs. geoserver.org/latest/en/user/geowebcache/rest/seed.htm

Hi Even, Is it correct to say the workflow for OGR layer in MapServer is similar to that of QGIS? OGR features / geometries are loaded, and then converted into MapServer shapes using the OGRGeometry function [1]. Would using WKB here be any more performant? The PostGIS driver already has code to

Hi, Please find for review "RFC 92 text: WKB Only geometries" at https://github.com/OSGeo/gdal/pull/7149 This RFC provides shortcuts to avoid instantiation of full OGRGeometry instances in scenarios where only the WKB representation of geometries is needed. The hope is to save CPU time. Thi
