About the space needed, well, the old mapserver was as large as to keep all v0, cs, corine, osm coastline/river/road and SRTM (RAW) data. Now the new server would only have to host decoded data (the raw data is already available via e.g. the terraGIT infrastructure).
Here an example for file size relation between raw data and decoded data (barrencover shapefile from my lofoten cs):
and here for SRTM height data, also for the lofoten cs:
and finally for the airports:
so the only data which is more after processing is airport data (note that genapts already included height data!)
[EDIT]Fixed code
Here an example for file size relation between raw data and decoded data (barrencover shapefile from my lofoten cs):
Code: Select all
BarrenCover:
raw data: 949,0kB
ogr-decoded data: 775,3 kB
and here for SRTM height data, also for the lofoten cs:
Code: Select all
SRTM-3:
raw data: 190,5 MB
preprocessed data: 35,7 MB
and finally for the airports:
Code: Select all
airports:
raw data: 34,1 kB
genapts-processed data: 275,2 kB
so the only data which is more after processing is airport data (note that genapts already included height data!)
