Efficient management of irrigation systems largely depends on the availability of accurate and
up-to-date spatial information. The Pazhassi Irrigation Project in Kannur district plays a
significant role in supplying water for agricultural and domestic purposes. However, the
existing canal maps are outdated and lack the spatial accuracy required for effective
monitoring and planning. Modern geospatial technologies such as Geographic Information
System (GIS) and Global Positioning System (GPS) provide advanced tools for creating precise
and detailed canal network maps.
This study focuses on the Main Canal and Mahe branch of the Pazhassi Irrigation Project,
where canal alignment and structural features are represented more accurately through
geospatial mapping. The integration of GIS and GPS allows the creation of a georeferenced
database that includes essential irrigation structures such as regulators, sluices, bridges, and
aqueducts. This combination of field data and digital mapping ensures better visualization and
understanding of the canal system.
A detailed and accurate canal network map not only supports efficient water distribution but also
enhances decision-making for maintenance, modernization, and future expansion of the
irrigation system. The use of GIS and GPS in canal mapping demonstrates the importance of
technology in improving resource management, ensuring data accessibility, and promoting
sustainable irrigation practices.
