Remote Sensing and Geographic Information System (GIS) are very powerful tools for instructional use in different subject areas and by different school levels. For the in-service teacher training in the use of these geotechnologies two distance educations courses were created. The objective of this paper is to present the results obtained with this type of training offered to teachers of public and private schools from Brazil. Specially well-organized tutorials for guiding teachers on digital image processing techniques and GIS were made available for them. The material and method used has proved to be suitable, although only about 50% of the teachers had a good performance in the tasks proposed. The results showed the need to promote not only in-service teacher training courses but also pre-service teacher training.
