The USGS currently houses the institute at the Center for Earth Resources Observation and Science (EROS) in Sioux Falls, South Dakota. The LCI will address land cover topics from local to global scales, and in both domestic and international settings. The USGS through the Land Cover Institute serves as a facilitator for land cover and land use science, applications, and production functions. The institute assists in the availability and technical support of land cover data sets through increasing public and scientific awareness of the importance of land cover science. LCI continues, after the reorganization of the World Data Centers in 2009, serving as the World Data Center (WDC) for land cover data for access to, or information about, land cover data of the world

Geochron is a global database that hosts geochronologic and thermochronologic information from detrital minerals. Information included with each sample consists of a table with the essential isotopic information and ages, a table with basic geologic metadata (e.g., location, collector, publication, etc.), a Pb/U Concordia diagram, and a relative age probability diagram. This information can be accessed and viewed with any web browser, and depending on the level of access desired, can be designated as either private or public. Loading information into Geochron requires the use of U-Pb_Redux, a Java-based program that also provides enhanced capabilities for data reduction, plotting, and analysis. Instructions are provided for three different levels of interaction with Geochron: 1. Accessing samples that are already in the Geochron database. 2. Preparation of information for new samples, and then transfer to Arizona LaserChron Center personnel for uploading to Geochron. 3. Preparation of information and uploading to Geochron using U-Pb_Redux.
