Cycle component of hidrologi in the form of presipitasi, evapotranspirasi, run off and infiltrate very needed in agricultural sector in the form of planning of agriculture, planning of pattern plant, irrigation management, till floods disaster mitigasi and dryness in DAS. Determining component value of hidrologi can be conducted with empirical method in the form of model of hidrologi. However usage of model of hidrologi former still less is giving information which spesifik To get information assess component of hidrologi spasial which is specific to be needed data of spasial. Existence of Geographical Information System technology (GIS) as tools expected can visualizing and data management of spasial in data model vektor and raster (grid), data tekstual model and hidrologi model so that can yield information assess component of hidrologi spasial and analyse component value of hidrologi. Result of analysis of spasial during year 2001 got that sub of DAS Ciwidey in Februari have value run off high off, sub of DAS Citarik have value of evapotranspirasi biggest, sub of DAS Cisangkuy have value infiltrate biggest and sub of DAS Citarik identified as critical area because having coefficient value run off which tend to increase.
