Metadata - IconMetadata - Summary of data in the Atlas

The Atlas contains 591 water resources which includes 93 bays and 209 lakes and 281 rivers and the Gulf of Mexico . Data recorded in the Atlas reaches back 124 years, starting on Monday, January 1, 1900. The most recent data is from Thursday, March 28, 2024. Over 186,585,538 data samples have been included in the Atlas! The samples came from over 131 data sources provided by 45 different data providers. These people and agencies have helped make the Atlas an integral tool for managing our water resources.

Geographic Information Systems Data

Geographic Information Systems (GIS) data consists largely of land mapping and spatial data and is used in a wide variety of fields. The lay of the land can affect almost every aspect of life, including an area's culture, government, environment, and commerce, making GIS information important to everyone. Fields such as anthropology, medical science, and natural science use GIS to measure and predict the impact of geography on a region. By mapping water resources, the Atlas provides spatial information useful to citizens, water management professionals, and scientists alike. The following core datasets are processed as part of geospatial analyses, the results of which are presented directly within Atlas components:

Monitoring and Sampling Data

Citizens, scientists, and professionals all contribute to monitoring and sampling data in many ways. Citizens often provide information such as water levels data through volunteer programs. Scientists and professionals set up equipment at sampling stations for measuring attributes such as water quality and hydrology. They provide the data in various formats to the Atlas, which compiles, organizes, and presents the data to help people better understand the county's water resources.
