Service Roads

Driveways. A subset of Roadway Sub-Block. A single line, segmented at all intersections (alley , service road, drive, street, and driveway centerline types), representing each driveway in the District. They follow the general trend of the driveway and do not deviate due to parking lanes, turning lanes, etc. and contain address ranges for geocoding.

Blockface Segments are unbroken sections of the curb. A blockface can be made up of several subblocks, or just one subblock. There are blockfaces on both sides of the road, each dependent on an unbroken length of curb. For more information please visit DDOT's wiki page

LINZ Data Service (LDS) Item Page - NZ Addresses: Roads The dataset provides linear geometries against which official road names and street addresses can be recorded. Its purpose is also to enable automated meshblock address reports (for electoral and statistical purposes) so as to identify the presence of a road name in meshblocks where street addresses do not exist. For this dataset (as opposed to the NZ Roads Sections), individual road section geometries have been aggregated to a single road centreline geometry where those subsections share the same name, and are generally contiguous. Because some roads have multiple names for part of their lengths, some road centreline geometries will duplicate parts of other roads even though there is in reality only one road formation. Refer to the NZ Addresses Data Dictionary for detailed metadata and information. These road centrelines do not represent actual road formation, nor do they represent legal access. They must not be considered as topographic, cadastral, or legal. This dataset contains the core attributes of a road to support simple searching or provide a road name context for cadastral data views. Please note: This layer is updated (if updates are available) from the LINZ Data Service. See Details on the right for when data was last updated and LDS layer history for more. Layer availability is unaffected during updates. If you have any questions, please contact us at maps@linz.govt.nz

Roads and streets from OpenStreetMap (ways tagged highway), with their type, name, surface and other tags. OpenStreetMap is built by a community of mappers; completeness varies by place.

Parking zones created from collected sign data throughout Washington DC. Parking Zones are created between two parking restriction signs of the same type that point at each other, or between a sign and an intersection.
