This paper describes the use of web mapping technology in water resource and territory management. Its purpose is to share geographic data associated to the Dagua river watershed, located in the Valle del Cauca Department, Colombia. The methodology used consisted in 1) processing and transforming geographic data of the watershed, 2) using open source geographic representation formats, and 3) applying the digital mapping library “Leaflet” from JavaScript. As a result, an open source geoportal was created,which allows visualizing information maps of the basin by themes, allowing the superposition of layers, the selection of layers of information and the visualization of geographical maps. The article focuses on the importance that the use of new information and communication technologies has acquired their applicability in the generation of geographic information associated with the river basin, the identification of variables and situations that affect the river basin. Asa territorial planning unit and the applicability of web mapping technology in the transformation of geographic data to take them to the visualization of maps by the internet. Finally,it describes the characteristics of the developed geovisor
