Hello, Thank you for the reply, however my data is slightly different. Sorry that I did not make it clearer at the very beginning.
Actually I would like to import a dense, 3-d array of wind speed (a time series of grids, each grid point contains the wind speed value) The array is stored as a NetCDF file FIles are here https://www.esrl.noaa.gov/psd/cgi-bin/db_search/DBListFiles.pl?did=61&tid=59909&vid=4298 The size of the array and its dimensions are below dimensions: lat = 94 ; lon = 192 ; time = 1460; The array short uwnd(time,lat,lon) ; uwnd:long_name = "6-Hourly Forecast of U-wind at 10 m" ; uwnd:valid_range = -32765s, -8765s ; uwnd:unpacked_valid_range = -120.f, 120.f ; uwnd:actual_range = -38.2f, 38.07f ; uwnd:units = "m/s" ; uwnd:add_offset = 207.65f ; uwnd:scale_factor = 0.01f ; uwnd:missing_value = 32766s ; uwnd:_FillValue = -32767s ; uwnd:precision = 2s ; uwnd:least_significant_digit = 1s ; uwnd:GRIB_id = 33s ; uwnd:GRIB_name = "U GRD" ; uwnd:var_desc = "u-wind" ; uwnd:dataset = "NCEP/DOE AMIP-II Reanalysis (Reanalysis-2)" ; uwnd:level_desc = "10 m" ; uwnd:statistic = "Individual Obs" ; uwnd:parent_stat = "Other" ; uwnd:standard_name = "eastward_wind" ; 2017-10-30 11:04 GMT+03:00 Giuseppe Broccolo <g.broccol...@gmail.com>: > Hi Antonio, > > 2017-10-29 12:31 GMT+01:00 Antonio Rodriges <antonio....@gmail.com>: >> >> Hello, >> >> Whether PostGIS allow importing 3-d, 4-d, etc. arrays or only 2-d arrays? >> >> Specifically, I have a 3-d array with axes (time, lat, lon). >> Does this mean that I need to split it onto 2-d bands (lat, lon) and >> import the number of bands that is equal to the number of time steps >> in the 3-d array? > > > Which is the data source from which you import the data (e.g. textual, > etc.)? > > If I've correctly understood, you have arrays where geospatial and > non-geospatial information > is present, each one providing a "dimension" of the array. > > Just FYI, in PostGIS is possible to define mixed, structured data with > constructors like POINTM > and POINT, that allow to add a further dimension to the 2D/3D (respectively) > geospatial ones, that > includes a scalar information. > > Hope this can help in your import, otherwise provide more information about > source data and how > you'd like to import. > > Giuseppe. > > > _______________________________________________ > postgis-users mailing list > postgis-users@lists.osgeo.org > https://lists.osgeo.org/mailman/listinfo/postgis-users _______________________________________________ postgis-users mailing list postgis-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/postgis-users
