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).

Mile Marker was derived from the Flat Sheet Sign feature layer. This dataset contains single points representing the flat sheet signs located on interstates, ramps, state routes, TDOT maintained state park roads, and locally owned NHS routes in Tennessee. This dataset can be queried by either location information, mounting type, sign orientation, sign type, visual condition, or MUTCD code. These records were derived from vehicle mounted LiDAR sensors and digitally captured photos. This information was collected by Mandli Communications, Inc. under the direction of the Asset Management Division and the Long Range Planning Division. Questions on this dataset should be directed to TDOT.Maint.AssetManagement@tn.gov.

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.

This is a vector point file showing mile markers at Great Smoky Mountains National Park (GRSM). Data were collected with GPS and/or aerial photography. Mile markers depict administrative distances on major roads and rivers within the park boundary. Mile markers shown on roads were derived from the Federal Highways Administration Road Inventory Program. To show the location of mile markers at Great Smoky Mountains National Park. The intended use of all data in the park's GIS library is to support diverse park activities including planning, management, maintenance, research, and interpretation. Mile markers are used for reporting purposes for facilities maintenance, as well as depicting locations of unnamed features (e.g. parking lots). Mile markers may not coincide with GPS or odometer information. Mile markers are intended for administrative use only, and should not be used for linear calibration purposes.The corresponding Integration of Resource Management Applications (IRMA) NPS Data Store reference is Great Smoky Mountains National Park Mile Markers.
