Daniel Pearson is the NWIS Modernization Program Manager for the USGS Water Resources Mission Area.
Daniel K. Pearson has been with the U.S. Geological Survey since 2002. In that time he has served as the Texas Water Science Center GIS Specialist, Data and Spatial Studies Section Chief, Geospatial Science + Cyber Innovation (GSCI) Branch Chief, and most recently the National Water Information System (NWIS) Modernization Program Manager. In those roles he has provided technical expertise and guidance to both cooperators and staff, and worked closely with a talented team of developers, geographers and hydrologists whose function was to produce innovative geospatial solutions; perform complex hydrologic and spatial analyses; and contribute to ongoing research within the USGS. Daniel has provided the vision over the last 10 years to transform the GSCI Branch in Austin, TX from a geospatial data production shop to an application development and data management enterprise. In his current role with NWIS Modernization he will provide the necessary improvements to NWIS, the worlds largest authoritative enterprise water information system, which is foundational to advancing USGS Water Mission Area priorities and meeting the needs of USGS and WMA stakeholders. Daniel earned a Bachelor’s of Science (2002) from Texas State University-San Marcos in GIScience and Cartographic Design. More information here: https://www.linkedin.com/in/danielkpearson/

The Texas Water Dashboard is a web mapping application that presents U.S. Geological Survey (USGS) real-time stream, lake, reservoir, precipitation, and well data in Texas in context with current weather and hazard conditions. Real-time measurements from over 750 USGS observation stations in Texas are accessible from the map viewer, along with complementary map layers such as current precipitation...Streamer
Streamer is an online mapping application for exploring downstream and upstream along America’s rivers and streams. Since Streamer was first released in 2013, scientists, water managers, students, and citizens have used Streamer extensively. The mobile friendly version takes most of the features from the desktop version and packages them into an intuitive, easy-to-use format on a smartphone or...Geolog Locator
The Geolog Locator allows users to search more than 7,000 digital borehole geophysical logs at over 1,700 locations. Users like hydrogeologists, groundwater hydrologists, and geologists can search and explore the online database, which primarily includes information collected by the USGS, as well some data compiled from other sources with permission.USGS Search API
The Search API is a location search tool for locations contained in the Geographic Names Information System (GNIS) database. This API is suitable for hydrologically-centric applications, excludes commercial locations, is customizable, is intuitive to use, and performs well.Water On-The-Go
“Water On-the-Go” is a map-based web application that gives people easy access to current conditions in streams across Texas. It was developed to help raise water awareness during floods and normal conditions. The mobile-friendly website offers three ways to view streamflow or other data, including using your phone’s GPS system, clicking on an area of interest, or by searching for a physical...GWWebFlow
GWWebFlow is a browser-based groundwater model viewer designed to allow users to easily explore model inputs and outputs for published and approved USGS models.
