FAA-Terminal Area Chart Baltimore-Washington from 2011. Like the VFR sectional charts that they complement, terminal area charts depict topographic features and other information of interest to aviators flying visually, including major landmarks, terrain elevations, visual navigation routes, ground-based navigation aids, airports, rivers, cities, and airspace boundaries.
Sectional charts are in 1:500,000 scale and are named for a city on the map. The Federal Aviation Administration (FAA) in the United States publishes over 50 charts covering the continental United States, Alaska, and Hawaii. Sectional charts are published by the National Aeronautical Navigation Services Group of the FAA.
The other option is to store the location and style of each label in the map data, just like the rest of the map; this is typically called annotation. [21] Text can be modeled as a Geometric primitive , like points, lines, and polygons, and in graphics software , it is stored in the map document in the same way as other geometry, allowing for ...
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 ]
If a map labeling problem can be reduced to a situation in which each remaining label has only two potential positions in which it can be placed, then it may be solved efficiently by using an instance of 2-satisfiability to find a placement avoiding any conflicting pairs of placements; several exact and approximate label placement algorithms ...
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 ...

Create a test map in your sandbox. You'll need to use {} together with the Wikidata ID of the shape. As an example: {{maplink|frame=yes|type=shape|id=Q160236}} If it displays, great. You can use the map and add parameters to make it display to your liking. If the map data does not populate, the below methods are straight-forward and reliable:
