BetaBetaDataset
To provide public access to authoritative geospatial datasets related to Hawaii’s water resources, watersheds, hydrology, environmental features, and natural resource management
The Watershed and Water Resources Collection is part of the Hawaii Statewide GIS Program Geoportal, a centralized platform for discovering, accessing, and downloading geospatial data maintained by state agencies and partner organizations. The collection focuses on water-related geographic information, including watershed boundaries, hydrologic units, surface water resources, and environmental datasets
The collection contains geospatial datasets related to watersheds, hydrologic unit boundaries, drainage basins, surface water catchments, streams, rivers, water resource features, hydrographic networks, environmental monitoring layers, natural resource management datasets, and associated geographic information. Resources include watershed delineations for the main Hawaiian Islands, hydrologic catchment boundaries, water-related environmental layers, downloadable GIS datasets, feature services, and interactive mapping resources that support watershed management, hydrologic analysis, conservation planning, and environmental assessment
Datasets are developed and maintained by Hawaii state agencies and partner organizations through GIS mapping, hydrologic assessments, environmental monitoring programs, watershed delineation studies, field surveys, remote sensing, and administrative data collection. The data are standardized and published through the Hawaii Statewide GIS Program Geoportal, where users can search, visualize, and download resources in multiple GIS-compatible formats. Methodologies vary according to the source dataset and contributing agency
