Import Data

This page describes how to import Raster (Grid), Vector and field data.

Raster Data
Most raster data formats can be dragged and dropped into straight into SAGA GIS, a comprehensive set of import tools in the:

Geoprocessing>File>Grid>Import>Import  Raster

Note: you may find that dragging and dropping raster data will use a default averaging (B-Spline) resampling method. This will change (average) the values of the imported pixels. To make sure the you keep the same values for imported data you will need to change the resampling method to Nearest Neighbour as shown below.


When you save rater data from SAGA-GIS it will be saved in the SAGA grig format .srgd.


Vector Data

  • Shape Files

Shape files can be loaded by either dragging and dropping the .shp file into saga or opening the file through the data tab or through top menu File>Shapes>Load

  • Google Earth KML


If you have made a point, line or polygon in Google Earth using the drawing tools you can import them into SAGA after first saving as a KML file. Then use:

Geoprocessing> File> Shapes> Import Shapes

You then need to define define the type of KML file you are importing (point, line or polygon) as shown below. This will import the vector layer into the SAGA data tab.



Field Data.

  • GPX files from a GPS and be simply dragged and dropped into SAGA, they shold automatically be imported.
  • Tables. If your field data is in the form of a table with coordinate information .

For example in the table below has been entered into excel from hardcopy field notes.


6Save from excel as a .csv  or txt (tab delimited format) file


The table can be simply drag-and-dropped into saga. it will appear as a new table layer in the data tab. To import this as attributed point data use:

Geoprocessing > Shapes>Conversion>Convert table to points

Choose the new table layer as the tabel to be coverted and x as your Easting (or Latitude) and Y axis as you Northing (or Longitute) values.


This will then add will then add a new point data layer.
