The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). In addition to the preceding, required text, the Abstract should also describe the projection and coordinate system as well as a general statement about horizontal accuracy.

Electric Service Territories (IURC) - Shows the Electric Service Territory (EST) boundaries in Indiana, maintained by personnel of the Indiana Utility Regulatory Commission (IURC). This layer is "live" and synchronized to automatically update whenever IURC personnel establish new boundaries.The layer was created to visually represent, as accurately as possible, the electric service territories served by the regulated electric service providers in the state of Indiana, pursuant to Cause Number 42868 (Indiana Utility Regulatory Commission) to establish an online GIS mapping environment to house, edit, and display visual interpretations or electric service territory rulings filed before and ruled by the Indiana Utility Regulatory Commission. The data represented in this layer is strictly a visual aide and a best interpretation of the legally approved Electric Service Territories as ruled by the Indiana Utility Regulatory Commission (IURC). These data are not legally binding or necessarily fully representative of the legal rulings.The following is excerpted from metadata provided by the IURC: "IN THE MATTER OF THE JOINT PETITION OF ELECTRICITY SUPPLIERS FOR (1) THE ESTABLISHMENT OF THE PROCEDURES TO APPROVE SERVICE AREA BOUNDARY AGREEMENTS UNDER IC 8-1-2.3-6(2) AND SERVICE CONSENTS UNDER IC 8-1-2.3-4(A), AND (2) MODIFICATION OF THE FORM AND MAINTENANCE OF MAPS OF ASSIGNED SERVICE AREAS ESTABLISHED PURSUANT TO IC 8-1-2.3-1, ET SEQ. AND THE COMMISSION'S FEBRUARY 19, 1981 ORDER IN CAUSE NO. 36299"

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk Information And supporting data used to develop the risk data. The primary risk; classificatons used are the 1-percent-annual-chance flood event, the 0.2-percent- annual-chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). The file is georeferenced to earth's surface using the UTM projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000.

The purpose of this map is to assist in retrieving digitized PLSS notes and plats. Indiana has three to four sets of "original" PLSS notes and plats.The field survey set, which the field surveyor originally wrote, is preserved at the Indiana State Archive for approximately 30% of the counties in Indiana.The federal set, which the GLO transcribed, is preserved at the National Archive.The state set, which the GLO transcribed, is preserved at the Indiana State ArchiveThe county sets, transcribed later from the state set by the state auditor, are available from each county surveyor.The file name indicates the source and geographical location within the PLSS. O for the Original set F for the Federal set S for the State set C** for the County set PM0* for the 1st or 2nd Principal Meridian T**N or T**S for the Township (North & South) R**E or R**W for the Range (East & West)This project was made possible by Clayton J. Hogston, who donated over 11,000 hours to create the linked documents. Other contributors include Clayton J. Hogston – Sphere Surveying Co., Lorraine Wright – Rock Solid GIS, Rachel Savich Oser – Oser Surveying & Mapping LLC, and county surveyors with support from the Indiana State Archives, chapters of the Indiana Society of Professional Land Surveyors (ISPLS), the Indiana Geographic Information Council (IGIC), the Indiana Professional Land Surveyors Foundation (IPLSF), and others.Detailed metadata regarding the location of the physical documents within the holding institutions is available on our Internet Archive pages, where the digitized records can also be viewed or downloaded in bulk.

From 1985 to 1994, a series of reports on coal resources of selected counties in Indiana was published as part of the Special Report series of the Indiana Geological Survey. These reports included maps showing elevation of the Hymera Coal Member (Dugger Formation, Pennsylvanian). The elevation maps were based on coal-test records and interpretations of geophysical logs that are included in the files of the Indiana Geological Survey. Data points were plotted by coal geologists of the Indiana Geological Survey and elevation contours were drawn by hand. The original work maps were compiled at a scale of 0.5 inch = 1 mile (1:126,720). Following completion of the investigations, the work maps showing elevation contours were subsequently scanned and digitized, and the resulting county coverages were then compiled into a single multi-county coverage. Elevations are given in feet, and the contour interval is 20 feet. Since the completion of this shapefile, additional data on coalbed elevations in selected areas has been obtained by the Indiana Geological Survey; interested users may wish to contact the Indiana Geological Survey for information on these more up-to-date sources.

From 1985 to 1994, a series of reports on coal resources of selected counties in Indiana was published as part of the Special Report series of the Indiana Geological Survey. These reports included maps showing thickness of the Danville Coal Member (Dugger Formation, Pennsylvanian). The thickness maps were based on coal-test records, mine-map notations, and interpretations of geophysical logs that are included in the files of the Indiana Geological Survey. Data points were plotted by coal geologists of the Indiana Geological Survey and thickness contours were drawn by hand. The original work maps were compiled at a scale of 0.5 inch = 1 mile (scale, 1:126,720). Following completion of the investigations, the work maps showing thickness contours were subsequently scanned and digitized, and the resulting county coverages were then compiled into a single multicounty coverage. Different thickness ranges were utilized in the various counties; these thickness ranges (given in feet) are retained in the final map. Since the completion of this shapefile, additional data on coal thicknesses in selected areas has been obtained by the Indiana Geological Survey; interested users may wish to contact the Indiana Geological Survey for information on these more up-to-date sources.

This data set shows Indiana's nine district boundaries (redistricted boundaries were adopted in May 2011 until 2021) for the 116th U.S. Congress and provides the name, party affiliation, and additional contact information for each of the representatives. The 116th U.S. Congress, Session I began on January 3, 2019. NOTE: A new Congress begins at noon January 3 of each odd-numbered year following a general election, unless it designates a different day by law. A Congress lasts for two years, with each year constituting a separate session. NOTE: Redistricting of all Indiana legislative boundaries were adopted in May 2011, and will be used from 2011 through 2021. Republicans who controlled the Indiana House and Senate from the 117th General Assembly oversaw the drawing of new maps in the Spring of 2011 for all 100 state house and 50 state senate districts and Indiana's nine congressional seats. New political districts are drawn every 10 years to incorporate information from the latest U.S. Census.
