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.

Mile markers for select Boulder County roads and CDOT roads. The Boulder County roads were initially selected based on historic precedent, referencing printed maps in the Public Works (formerly Transportation) Department. Markers for more roads may be added after further review. Historic roads included some within municipalities, and mile markers were retained for those roads, regardless of annexations.Mile marker points along County roads were measured using GIS. Each road length was calculated using GIS, depending on accuracy from the Colorado StatePlane coordinate system and then accounting for slope from a 2.5 foot DEM. Markers, every quarter mile, were located along routes using a linear referencing method.Markers on CDOT roads were selected from a feature service owned by them. The selected roads were based on the Road_Map_Roads feature class.Note: Road Maintenance mile posts will be move based on markers in this dataset.

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

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).

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.
