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).

Vector polygon map data of mile markers from the State of Utah containing 5758 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 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.

Reference Post locations on the Nebraska Highways.

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.

Depicts green mile marker signs that provide approximate mileage along NMDOT owned and maintained routes. Due to construction, vandalism, etc., the locations of milepost signs might be adjusted by NMDOT.Please select Milepost Interval Layers for Downloading Data

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.

Reference posts (often called Mile Post or Mile Markers) are green numbered signs along the side of a highway roughly a mile apart for traveler reference.

The Trail Mile Marker dataset includes mile marker locations on the sections of the Anacostia River Trail, Metropolitan Branch Trail, and Klingle Valley Trail. The markers are generally marked every tenth of a mile with a sign and/or pavement marking. Mile markers are used to report maintenance needs and assist in emergency response.

This data contains the location and legend of mileposts markers (signs) on state owned highways.This GIS base layer can be used for planning purposes and as a reference layer on standard Oregon Department of Transportation (ODOT) city and county map formats.

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.

Contains 11,201 sequential mile positions of navigable inland waterways and the Gulf Intracoastal Waterway. Records include eight fields; id, latitude, longitude, mile, river code, river name, river number, source .

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.

Colorado Highway and Frontage road milepost locations. Mileposts are locations of milepost (mile marker) locations alongside CDOT highways, collected during GPS mapping efforts in the early 2000s. MIleposts differ from milepoints in that milepoints represent the location along CDOT highways where that highway's linear reference system indicates a whole number reference point (such as 57.000). Therefore, mileposts are not necessarily found at exactly at milepoints. Also includes collection date of point, route ID and some GPS locations.

Remote sensing maps of active layer depth derived from Unmanned Areal System (UAS) data. The UAS datasets were stepwise scaled until matching the AVIRIS-NG (Airborne Visible / Infrared Imaging Spectrometer - Next Generation) and Sentinel-2 spatial resolutions. Using the field observed Active Layer Depth (ALD) measurement in combination with spectral and topographic predictors derivatives from DJI UAS imagery, we used a spatially explicit RF regression model to predict and map ALD across our study landscapes. This package includes maps for Next-Generation Ecosystem Experiment Arctic (NGEE Arctic)’s Teller Mile Marker (MM) 27, and Kougarok MM80 (aka Mile 80) watersheds. The field, map data, and metadata are provided as geoTIF and text (*.csv) formats. These datasets are provided in support of Hantson et al., 2024 (accepted) “Scaling Arctic landscape and permafrost features improves active layer depth modeling”

The FRA Milepost is a spatial file that originates of multiple sources and contains point locations of mileposts along the FRA's rail network. The mileposts was developed from varies sources and should only be used as a reference file. The railroad lines and their mileposts are privately owned and are subjected of changed based on the rail owner. If used for identifying specific locations, please contact the railroad to verify the mileposts numbers and their locations.

Mileage markers, also often called kilometer markers, allow road users and safety workers to use road signs to locate on the road network. Mileage markers are installed on all motorways and they can also be installed on other classes of roads (e.g. national road) where there are tracking problems or an absence of services.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
