now supporting QGis 1.1 current development version
Disclaimer: this one is an alpha preview release: i.e., this SW
is expected to be strongly unstable.|
You are welcomed to use it for testing purposes, but you are warned not to use it for any other practical purpose.
|this one is a very simple test DB, using only 3 layers
basically it's the standard SpatiaLite test DB
|a more realistic test bed, based on GIS data sets
availabale for public download
on the Merano Local Council WEB site.
Merano is a medium sized town [36.000 peoples], and the whole data set counts some 250.000 geometric features.
I presume this one can be considered as a quite heavy [and thus realistic] example
|exactly the same as above, but using R*Tree Spatial Indices for each layer
counting more than 1.000 features.
Using Spatial Indices introduces obvious speed benefits, but not so dramatic as you can expect; this 250.000 rows dataset simply is too small to take full advantage from spatial indices.
As from my preliminary tests, you can really notice the difference spatial indices can do only when using a 1 million rows (or more) dataset.
|another variation on the theme, this time using MBR-cached Spatial Indices for each layer counting more than 1.000 features.||17 MB||merano-cached.7z|
