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

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.

The feature layer contains mile marker signs found along all Interstate Highways and Appalachian Highway Corridors. Information included in this layer includes the Route Information, FAB Code, Sign Text, sign size, Coordinates, and Collection Date. Data is current as of January 1, 2021 and is updated as needed.Coordinate System : NAD_1983_UTM_Zone_17N

Mile Marker points for Pennsylvania Interstates. For more information on this layer, you can use the Data Dictionary.

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

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).

Point features which represent the locations of mile marker signs along public roadways in the State of Maryland. Roadway Mile Markers data is developed as part of the Highway Performance Monitoring System (HPMS) which maintains and reports transportation related information to the Federal Highway Administration (FHWA) on an annual basis. HPMS is maintained by the Maryland Department of Transportation State Highway Administration (MDOT SHA), under the Office of Planning and Preliminary Engineering (OPPE) Data Services Division (DSD). This data is used by various modules throughout MDOT, as well as many other State and local government agencies for purposes such as planning, land use, transportation, data & asset collection. Roadway Mile Markers data is published on an annual (yearly) basis for the prior year.

Sequential mile positions of navigable inland waterways and the Gulf Intracoastal Waterway.

This label service is generated from a subset of the Common Places layer maintained by the Tallahassee - Leon County Consolidated Dispatch Agency. This label service displays mile markers on Interstate 10 and Orchard Pond Parkway. Because Interstates are limited access roadways, they do not include address ranges, which makes mile markers a critical location reference for first responders. While the Common Places layer is actively edited by staff at the Consolidated Dispatch Agency and Emergency Management, the Mile Marker subset is considered static.

The Navigation Mile Marker dataset is a collection of over 11,000 waterway milepoints that describe the physical locations of individual mile-markers along inland navigation waterways in the United States. The file includes data primarily sourced from the Corps of Engineers Inland Electronic Navigation Charts (IENC) and additionally contains milepoints from the National Oceanic Atmospheric Administration (NOAA), USACE Corps of Engineers Districts (Corps) and other various data sources. The data includes location (latitude, longitude, waterway, mile). Additional attributes included in the data are the unique navigation-unit identifier, waterway name, waterway number, and source.
