currently, setting host, port, database is mandatory in the C++ and Java API. This should provide the well-known defaults to simplify application programming. This should be all needed for localhost:

database.open();

…and we even could make this fully automatic allowing to avoid database open (and, similarly, for transactions where we transparently could allocate one by default).

rasdaman has a problem now with operation with null values (in this case is: -9999 of a test coverage), for example:

rasql -q ' SELECT encode( count_cells(c[0,0:100,0:231] > -9999) , "csv" ) FROM test_eobstest AS c' --out string
Result object 1: 0
rasql done.

rasql -q ' SELECT encode( count_cells(c[0,0:100,0:231] > -9998) , "csv" ) FROM test_eobstest AS c' --out string
Result object 1: 6774
rasql done.

Here is the generated rasql from WCPS:

for c in (test_eobstest) return encode(
count(c[t("1950-01-01")] >= -9999)
,"csv")

SELECT encode( count_cells(c[0,0:100,0:231] >= -9999) , "csv" ) FROM test_eobstest AS c 

which also returns 0.

Each 2D and 3D geo-refereced coverage should have a Preview button / link next to its name in the WCS and WMS Capability tabs.

When the user clicks on the preview button:

• for 2D coverages, a scaled down version of the coverage data is displayed on the globe and the view is centered in the middle of the coverage

• for 3D coverages, a scaled down version of the first slice is displayed on the globe, and a slider will let the user change the slice being displayed.
