This figure shows a smaller window open within the California State Water Resources Control Board page on Cal Open Data Portal, providing straightforward access to an Excel document displaying a dataset within the state 2019 water quality status report that sampled 1,2,3-trichloropropane, a drinking water contaminant.

Each federal state organization has the number of open datasets listed below them, and is also available to click on to discover those datasets.

Cal Open Data Portal demonstrates that it is able to bring together different datasets from various government agencies. It also allows for open data to be linked across different existing datasets.

Cal Open Data Portal draws data from state agencies. Census tracts can be searched for, for example, searching for Census Tract Disadvantaged Communities 2018, opens a synopsis and map showing each tract and its attributes. However, some of these data sets are linked to GIS programs, meaning they could be layers that are created to add to a map, making it difficult for non-GIS users to navigate and understand. In an attempt to provide assistance with this measure, the website provides a guidebook and a public open data training video for a user to learn how to find data and produce data visualizations. 

California Open Data Portal is designed to host open data from more than one state agency and aims to link all existing state portals in order for California's open data sets to be easily searched for from https://data.ca.gov. Open data or public data is collected through the state's routine business activities and is published in a way that is simple to search for, download, and combine with other data. Open data does not include private or confidential information on individuals.

Government Operations Agency aims to create a statewide open data portal intended to improve collaboration, expand transparency and lead to increased effectiveness. Despite the already existing open data portals hosted by several state agencies, this resource is made to host data from more than one agency.
