Represents public road centerlines in the state of Maine. Created by Maine Department of Transportation using MaineDOT's basemap linework managed in METRANS, MaineDOT's Linear Referencing System (LRS). MaineDOT_Public_Roads includes the most commonly-used attributes such as traffic volumes, federal functional classifications, jurisdiction, priority and more. This is updated regularly through a service, although the AGOL "Updated" date may only reflect the date this feature layer was created.Route and Road names: While MaineDOT's record of "Streetname" attribute is included and matches the official NG911 names whenever possible, the official road names are reflected in the NG911 (a.k.a. E911) data available from the Maine Geolibrary While multiple route designations (US Route 202, State Route 27, etc.) may be co-located on any given road, this dataset only shows the "primary" route.This dataset is designed for use in applications within MaineDOT.

This crash dataset does include crashes from 2023 up until near the middle of July that have been reviewed and loaded into the Maine DOT Asset Warehouse. This crash dataset is static and was put together as an example showing the clustering functionality in ArcGIS Online. In addition the dataset was designed with columns that include data items at the Unit and Persons levels of a crash. The feature layer visualization by default will show the crashes aggregated by the predominant crash type along the corridor. The aggregation settings can be toggled off if desired and crashes can be viewed by the type of crash. Both the aggregation and standard Feature Layer configurations do include popup settings that have been configured.As mentioned above, the Feature Layer itself has been configured to include a standard unique value renderer based on Crash Type and the layer also includes clustering aggregation configurations that could be toggled on or off if the user were to add this layer to a new ArcGIS Online Map. Clustering and aggregation options in ArcGIS Online provide functionality that is not yet available in the latest version of ArcGIS Pro (<=3.1). This additional configuration includes how to show the popup content for the cluster of crashes. Users interested in learning more about clustering and aggregation in ArcGIS Online and some more advanced options should see the following ESRI article (https://www.esri.com/arcgis-blog/products/arcgis-online/mapping/summarize-and-explore-point-clusters-with-arcade-in-popups/).Popups have been configured for both the clusters and the individual crashes. The individual crashes themselves do include multiple tables within a single text element. The bottom table does include data items that pertain to at a maximum of three units for a crash. If a crash includes just one unit then this bottom table will include only 2 columns. For each additional unit involved in a crash an additional column will appear listing out those data items that pertain to that unit up to a maximum of 3 units. There are crashes that do include more than 3 units and information for these additional units is not currently included in the dataset at the moment. The crash data items available in this Feature Layer representation includes many of the same data items from the Crash Layer (10 Years) that are available for use in Maine DOT's Public Map Viewer Application that can be accessed from the following link(https://www.maine.gov/mdot/mapviewer/?added=Crashes%20-%2010%20Years). However this crash data includes data items that are not yet available in other GIS Crash Departments used in visualizations by the department currently. These additional data items can be aggregated using other presentation types such as a Chart, but could also be filtered in the map. Users should refer to the unit count associated to each crash and be aware when a units information may not be visible in those situations where there are four or more units involved in a crash.

Vector Tile Services are used extensively in basemaps and cartography. These reference a set of vector tiles and a corresponding Style JSON file that instructs the map on how to render each feature. The vector data - in the form of points, lines, and polygons as well as images (called sprites) - contain only the data needed to draw the feature and apply the accompanying style. As such, vector tile services render quickly at different display resolutions when compared to traditional feature layers. To learn more about vector tiles: Vector Tiles - Wikipedia.To view and modify the Style component of this Vector Tile Service, you can use the ArcGIS Vector Tile Style Editor accessible through the hyperlink or the task button on the right. Modifications to the service's Style allow a user to reference the existing vector tiles without needing to duplicate them.This Vector Tile Service covers the State of Maine and uses local, state, and national data sources.LayerNameFeatureNameSourceShapeProperty Information\Building Footprints\Building TypesNG_ADDRESSESE911PointProperty Information\Building Footprints\Buildings ShadowsNG_FOOTPRINTSE911PolygonProperty Information\Building Footprints\BuildingsNG_FOOTPRINTS_TYPEE911PolygonAirports\Airport PointsAIRPORTSMEDOTPointRoads\Private RoadsE911_PRIVATEMEDOTPolylineRoads\Interstate InterchangesINTERSTATE_INTERCHANGESMEDOTPointFerry\Ferry RoutesFERRYRTE_STATEMEDOTPolylineRailroads\Railroads BridgeLINEAR_BRIDGEMEDOTPolylineRailroads\RailroadsRAILROUTE_SEGMENTSMEDOTPolylineRoads\TrailsTRAILSMEDOTPolylineWater\Streams NHDNHDFlowlineUSGSPolylineBoundaries\State Urban BoundarySTATEURBAN_CLIPMEDOTPolygonBoundaries\Conserved Landsconserved_landsDACFPolygonBoundaries\County PointsCOUNTIESCENTROIDSMEGISPointPlaces\Capes - Islands & SummitsGnis_lMEGISPointPlaces\CemeteriesGnis_pMEGISPointPlaces\Place Names & Populated PlacesGNIS_P_ENHANCEDMEGISPointContours\Contours - 10 ftMEGIS_ContoursMEGISPolylineBoundaries\Coastline & Political BoundariesMetwp24LMEGISPolylineBoundaries\State Background & Water - Metwp24pMetwp24pMEGISPolygonWater\Wetlands - NWINWI_2014MEGISPolygonWater\WQPondsWQPondsMEGISPolygonWater\WQRiversWQRiversMEGISPolygonAirports\Airport WaysNWR_Aeroway_Attr_osm_lnOpen Street MapPolylineRoads\One Way & Roads Base & BridgeROADSBASEMEDOTPolylineRoads\Route ShieldsROADSBASE_SHIELDSMEDOTPoint
