When importing large raster maps with {{cmd|r.in.gdal}} the default internal settings may be slow, with a large percentage of the CPU locked up in kernel system operations. In these cases you should increase the ''memory='' option to be larger than:

Setting the ''r.in.gdal memory='' option has the same effect as setting the GDAL_CACHEMAX environment variable.

Wprowadzanie swoich danych do systemu GRASS

GRASS obsługuje wiele popularnych formatów danych, a także wiele rzadkich.

The primary import/export tool is called GDAL/OGR. It is the Rosetta Stone of the free GIS world:

W oknie powitalnym programu, przy pomocy Kreatora lokacji utwórz nową lokację o właściwym układzie współrzędnych dla swoich danych. Następnie wybierz z menu:

Dla rastrów:  Plik → Import raster data using GDAL
Dla wektorów:  Plik → Import vector data using OGR

Zazwyczaj GDAL/OGR automatycznie wykryje format pliku.


After the map has been imported you can add it to the display layer list in the Layer Manager window. You will most likely want to right click on the map in the layer list and select "Zoom to selected map(s)". Otherwise when you go to view the map you could be far away and just see a white display canvas.

To view a raster map, add it to the Layer Manager with the grid-like button with a (+), to add a vector map to the Layer Manager use the button with lines and points on it to the right of the add raster map button. The left hand button in the Map Display window will re-render the map if needed.

The "computational region" is a very important concept in GRASS and is distinct from the "display window" you see in the Map Display window. You can also read about it in the rasterintro help page. You can set the computational region and cell resolution to match a specific map with the g.region module.

After importing your data you need to run "g.region -p rast=your_map" or "g.region -p vect=your_map" to set the region bounds/zoom to match that of the newly imported map. Be careful with the region resolution when doing this with vector maps, you may have to run "g.region -a res=" to clean that up and keep it reasonable (for example 2000x2000 rows and columns).

Duże dane

When importing large raster maps with r.in.gdal the default internal settings may be slow, with a large percentage of the CPU locked up in kernel system operations. In these cases you should increase the memory= option to be larger than:

tile_height * raster_width * band_count * sizeof_datatype

You can find those values with gdalinfo.

Setting the r.in.gdal memory= option has the same effect as setting the GDAL_CACHEMAX environment variable.
