This dataset contains borehole lithology data associated with a geothermal temperature depth survey. Each interval feature has a top (without a bottom), measured from the ground surface (convention for interoperability) and a geologic unit description that will be identical with the content associated with polygons on a geologic map. Other sheets in the workbook provide additional explanatory material and provide information on the origin of the dataset, its review and lineage, and a data terms sheet providing terms used in the data. 15,222 borehole intervals with lithology are represented in this dataset for the State of Iowa, provided by the Iowa Geological and Water Survey.

This dataset contains data provided by the Iowa Geological and Water Survey for heat pump facilities in the State of Iowa, including individual heat transfer installations (well, trench, pit) as well as facilities that aggregate more than one heat transfer installation. These features represent 2,785 residential facilities. There are 6 worksheets in this document, including information about the template, resource provider information, the data, and a list of possible data terms used in the data. Fields in the data include facility name, system type, heat application, date installed and drilled, driller depth, and location.

This dataset contains well log observations compiled by the Iowa Geological Survey, and published as a Web feature service for the National Geothermal Data System. Fields in the Well Log Observation Content Model will become XML elements in interchange documents for WMS simple features provided by a node in the USGIN network. Each observation includes a Log URI, API Number, Latitude and Longitude spatially referenced to EPSG: 4326 (for interoperability). The data contained in the submitted dataset is available as an Excel Spreadsheet, ESRI service, WMS and WFS service.

This spreadsheet is a compilation of observations compiled by the Iowa Geological and Water Survey, published as a Web feature service for the National Geothermal Data System. The document contains 8 worksheets, including information about the template, notes related to revisions of the template, Resource provider information, the data, a field list (data mapping view) and a worksheet with vocabularies for use in populating the spreadsheet (data valid terms). Data from 64047 wells are included.
