Remote and proximal sensing techniques make it possible to collect area-covering information from the earth's surface and the soil. Examples of these techniques are visible, near and mid infrared spectroscopy, gamma spectrometry, ground penetrating radar and electromagnetic induction methods. These techniques are potentially very useful in keeping the soil information up to date and increasing the resolution and accuracy of this information. Compared to traditional mapping methods, they provide detailed area-covering information that can be utilized in scaling up point observations to area-wide information using Digital Soil Mapping at relatively low cost. This project investigates the usefulness of these techniques for updating the soil map of the Netherlands in a literature study of validation results.
