[gdal-dev] memory problems with huge raster sizes

2014-02-13 Thread Dennis Gocke
Hi, We've stumbled upon memory problems when using huge raster levels. For instance for a common TMS/WMS server on the full level you will have something like: Raster Size: 268435456x268435456 Block Size: 256x256 With SUBBLOCK_SIZE 64 this results in: nSubBlocksPerRow = 268435456 / 256

Chuiqing, The OGR Shapefile driver supports spatial indexing through qix files. To explicitly create a spatial index use the Create Index command: CREATE SPATIAL INDEX ON tablename [DEPTH N] Depth can range from 1 to 12. You can issue the SQL command using ogrinfo. ogrinfo -sql 'CREATE SPATIAL

Chuiqing, You can create an index through SQL. This is the preferred method even if you stick to the shapefile format for your vector data. OGRDataSource::ExecuteSQL() OGR's Shapefile driver supports these SQL commands among others: CREATE SPATIAL INDEX ON layer_name [DEPTH n] DROP SPATIAL
