The street hierarchy is an urban planning technique for laying out road networks that exclude automobile through-traffic from developed areas. It is conceived as a hierarchy of roads that embeds the link importance of each road type in the network topology (the connectivity of the nodes to each other).
The PDF format is widely accepted and is considered the de facto standard for printable documents on the web. This means that users do not require the any proprietary plug-in to read geospatial PDFs created following the PDF 1.7 specification, which was published as ISO 32000-1 standard . [ 3 ]

At the top of the hierarchy in terms of traffic flow and speed are controlled-access highways; their defining characteristic is the control of access to and from the road, meaning that the road cannot be directly accessed from properties or other roads, but only from specific connector roads.
GeoPDF is a line of map and imagery products created by TerraGo software applications. GeoPDF products use geospatial PDF as a container for maps, imagery, and other data used to deliver an enhanced user experience in TerraGo applications. However, GeoPDF products conform to published specifications including both the OGC best practice for PDF ...
Two strategies have been used to integrate the geometry and attributes into a single vector file format structure: [13] A georelational format stores them as two separate files, with the geometry and attributes of each object being linked by file ordering or a primary key. This was most common from the 1970s through the early 1990s, because GIS ...

[3] It is a concept used in transport reform groups worldwide [4] [5] and in policy ...
Geographic Data Files (GDF) is an interchange file format for geographic data. In contrast with generic GIS formats , GDF provides detailed rules for data capture and representation, and an extensive catalog of standard features, attributes and relationships.
