Sizes of GeoPackage and Spatialite DBs should be very similar in most cases.
They differ only by the geometry encoding, which in both cases is more or less
a header + WKB or a variant of WKB. Spatialite DBs can be significant
My next choice for customers (in cases of a hard file requirement) is
always Spatialite (sqlite3 + libspatialite wrapped into a single file).
I still prefer and use that to deliver, over the heavier GPK format.
(again, everyone has their own preferences, I'm just sharing my 18+
years of MapServ
Ah right of course! I should have said that we deliver these things to
customers, so a file format is needed. We've have had good luck serving
simplified versions of these things out of zipped shapefiles from S3 via
mapserver so the thought was maybe the same trick would work with the right
forma
Hi Patrick,
In terms of speed and MapServer, considering you have large vector data
and require good indexing, I always use and recommend PostGIS.
(of course if you asked this on the MapServer-users list you would get a
whole lot of different opinions)
But that is my initial recommendation,
Hi all,
I've been trying to figure out a good format to store some very large
vector data in. Basically, its a bunch of really dense polygons describing
the cutlines that compose a mosaic. We've had reasonable success using
zipped shapefiles, but on the larger guys we're exceeding the 2GB file

Christoph,
gdaladdo always start from the full resolution layer (or the preceding
overview in case of cascading overview), hence what you observe. And even if
it did start from the nearest existing overview level, in your full scenario

Hi,
I have a use case where I would like to update some parts of my dataset
and not have to re-render all the overviews for all the other parts of
the globe. My idea was to use 5x5 degree boxes for which I would create
overviews of levels e.g. 2, 4, 8, 16. Then I would use a global VRT of

I want to recalculate pixel values of raster based on raster stats. In terms
of gdal, I want to use gdal_calc together with gdal_stats. Is it possible to
somehow pass an output of gdal_stats into gdal_calc?
In particular, I need to recalculate pixel value based on standard deviation
