SHYLOC is a user-friendly software package, written in the C++ objected oriented programming language, that can read and process remotely sensed data (e.g. Landsat Thematic Mapper- TM or SPOT images) and digitised ditch, stream or river vector data.

By means of combining these two components together SHYLOC calculates satellite-derived surface water areas and wet ditch widths in a network of drainage or irrigation channel, ditches, streams or rivers. Such satellite-derived information can be combined with ground-based measurements (e.g. surface water levels, ditch morphology) to:

1. Produce statistical relationships between satellite-derived information (e.g. effective wet ditch width) and ground-based measurements (e.g. surface water levels), which can thereafter be used to (a) provide insight into historical conditions in wetlands through the use of historical remote sensing images, that otherwise would not be available, (b) monitor areas of water management/ abstraction issues and (c) calibration data for wetland hydrological models.

2. Estimate volume of water stored in networks of drainage or irrigation channels, ditches, streams or rivers.

3. Provide assessments of water levels through out stream or ditch networks instead of at individual point locations, which characterise ground-based monitoring.
