[R-sig-Geo] tpk files

[Roger Bivand]

Briefly, could you use the proxy interface in stars and subset without reading the whole object? I'm not able to check now, but if the data are raster layers, perhaps temporal, stars may be helpful.

Hi Barry, Thank you so much for your quik reply! Yep, I tried that... after downloading, changing the name and decompressing (it becomes 27GB), then I was not able to read it with r. I will try again then. Cheers, M. PS: now, it is giving me an error: Error in CPL_read_ogr(dsn, layer, query, as.character(options), quiet, : std::bad_alloc In addition: Warning message: In CPL_read_ogr(dsn, layer, query, as.character(options), quiet, : GDAL Error 1: In GetNextRawFeature(): sqlite3_step() : disk I/O error > Barry Rowlingson escreveu no dia quinta, 11/04/2019 à(s) 16:39: > What did you try?
