Vector polygon map data of mile markers from the state of California containing 157892 features.

Mile marker GIS data consists of points along a linear feature, such as roads or railways. They serve as reference points to measure distances along these features. Mile markers are often labeled with numbers indicating their distance from a starting point, such as a highway's origin or a railway station.

These markers are invaluable for navigation, route planning, emergency response, and data collection. For example, they help drivers and emergency services identify their location precisely on a road. In transportation planning, mile markers aid in analyzing traffic patterns, determining optimal routes, and estimating travel times. Additionally, they facilitate maintenance activities by providing clear reference points for inspecting and repairing infrastructure.

This data is available for viewing and sharing as a map in a Koordinates map viewer. This data is also available for export to DWG for CAD, PDF, KML, CSV, and GIS data formats, including Shapefile, MapInfo, and Geodatabase.

In general, the mile markers are measured from west to east and south to north. Such as I-10 starting in Escambia County, bordering Alabama, with mile marker 1 then increases eastward. And for I-95 from Miami-Dade County starting with mile marker 1 then increases northward. The data is refreshed weekly and changes are made by the District Offices who are responsible to collect and upkeep the data. This data may also be collected for call boxes that are located at integral milepoints instead of the usual mile marker signs. This data is required for all interstate, tolled or non-tolled expressway facilities, and US routes. This dataset is maintained by the Transportation Data & Analytics office (TDA). The source spatial data for this hosted feature layer was created on: 07/05/2025.For more details please review the FDOT RCI Handbook Download Data: Enter Guest as Username to download the source shapefile from here: https://ftp.fdot.gov/file/d/FTP/FDOT/co/planning/transtat/gis/shapefiles/milemarkers.zip

The Mile Marker Inventory contains mile marker location information along Michigan's highways. Descriptive information for the mile markers include: latitude and longitude, route name, region, TSC, county, control section number, physical reference (PR) number, PR mile point, and mile number. The information was collected in 2011 using Framework V11. The data has not been updated and more current data may be available. Please see the MDOT Metadata Form for additional information. Update Cycle: The Mile Marker inventory was initially collected and completed in 2011 as part of the Lane Mile Inventory (LMI). There is currently no update plan in place to re-collect or update this inventory.Data Quality: Data was collected to +/- 25ft accuracy using a laptop equipped with ArcGIS Desktop and a tethered USB puck GPS unit.Coverage: This inventory is complete in its coverage of all State of Michigan trunkline roadways as of 2011.Symbology: The symbology for the Mile Markers is a simple point.Contact: Alonso Uzcategui, uzcateguia@michigan.gov

This dynamic map service provides a general linear referencing system used to locate highway characteristics and events. These milepoints are spaced at 1/10th of a mile intervals.

Part of the emergency response facilities layers, the mile markers contribute to emergency response. This is a point layer featuring the mile marker locations on the highways throughout the county. The data was last updated in 2014 and is not maintained by SCGIS. Mile markers on highways provide a more precise location during emergencies. Those seeking emergency assistance on a highway can report to dispatchers the closest mile marker and help get a faster response.

The purpose of this data set is to provide a geographic representation of the location of each state mile marker sign in the Commonwealth, and is to be used in a number of other products and projects. The locations of state mile marker signs on interstates and primary routes are important sources for various traffic studies as well as information for travelers. This GIS layer displays the locations and corresponding information of state mile marker signs. The signs may have been placed close but not exactly at the mile point due to geographic restrictions.Attribute NameContentsFIDInternal Feature NumberShapeFeature GeometryHTRISDEFHTRIS Definition in the Roadway InventoryROADSIDELocations of Mile Marker Posts (Right, Left, or Median)LATITUDEGPS latitude for each Mile Marker point in decimal degreesLONGITUDEGPS longitude for each Mile Marker point in decimal degreesSIGNSTYLE0: Small & Non-MUTCD Compliant, 1: MUTCD Standard (D10-1, D10-2 or D10-3), 2: MUTCD Enhanced (D10-4 or D10-5)SIGNVALUENumeric Value from the Sign Text except NULL, -1, and -2 valuesSIGNTEXTFull Sign TextM_JURISDICMaintenance Jurisdiction Code

This file contains the river mile marker locations on the printed digital flood insurance map. The National Flood Hazard Layer (NFHL) data incorporates all Digital Flood Insurance Rate Map(DFIRM) databases published by FEMA, and any Letters Of Map Revision (LOMRs) that have been issued against those databases since their publication date. The DFIRM Database is the digital, geospatial version of the flood hazard information shown on the published paper Flood Insurance Rate Maps(FIRMs). 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 NFHL data are 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 specifications for the horizontal control of DFIRM data are consistent with those required for mapping at a scale of 1:12,000. The NFHL data contain layers in the Standard DFIRM datasets except for S_Label_Pt and S_Label_Ld. The NFHL is available as State or US Territory data sets. Each State or Territory data set consists of all DFIRMs and corresponding LOMRs available on the publication date of the data set.

Location of the reference markers, or "Mileposts", on the Kansas Department of Transportation and Kansas Turnpike Authority maintained State Highway System. Information includes the route, mileage within the county, and Latitude-Longitude for each Reference Post. These markers are used as a reference a location along a highway. Generally the markers are spaced about a mile apart along rural highways, but it should not be assumed that these reference posts represent consistent or accurate mileage or miles traveled.
