[Qgis-user] Raster postGIS problema visualizar en QGIS

[Mike Treglia]

Is it a large raster? I don't have experience with remote postgis data, but I know that if I'm dealing with very large postgis rasters locally, it takes some time to render.

Hope that helps... I don't have a ton of experience with postgis, so I'm not sure what else could be going on.

>>> Hello Michael, thank you very much for your reply. My problem has been solved. Indeed, I was trying to import the postGIS raster from the wrong way, i.e., 'Add PostGIS layer', and when I load it from DB Manager plugin there is no problem, it was very easy but it was my first time. Thank you again.

Both columns 'rid' and 'rast' were successfully created but when I connect QGIS 2.0 to the data base and load the table, the software is unable to recognize the data type and the geometry type, so that I can not visualize the file and the attribute table has not the rast column.

Crea los campos 'rid' y 'rast' bien. Pero al conectarme a la base de datos con QGIS, la tabla postgres correspondiente viene como 'Tipo de dato' : Nada y 'Tipo espacial' : Ninguna geometría. Cuando añado el archivo y visualizo la tabla de atributos solo existe el campo 'rid' pero no el 'rast'.
