Data input
You need to ensure that your spatial and non-spatial data is available in digital form
in your computer. How you do this depends largely on the data type. For instance,
you can digitize maps and you can type tabular data. ILWIS can convert data files
derived from scanning, or you can import other digital formats as inputs. Through
image processing, ILWIS enables data input from remotely sensed images. The
aspects of spatial data input will be dealt with in the next chapter (chapter 3).
