What is the open source language for managing and displaying geographic data on the internet?

• A. Html
• B. Kml
• C. Xml
• D. Json

Answer: (B)

Geographic data on the web is best handled with a markup language specifically designed to express map features and how they should appear. This language encodes points, lines, polygons, and overlays with coordinates and styling, so mapping tools can render them directly in a browser or map application. It’s based on XML, which makes it easy to read and parse, and it’s an open standard used widely for geospatial visualization on the internet. That combination—a dedicated, open standard for describing geographic features and how they’re displayed—explains why it’s the best fit for managing and displaying geographic data online.

HTML structures web pages and isn’t about describing geographic features. XML is a general markup language without the map-specific constructs. JSON is a flexible data format; while GeoJSON exists for geographic data, it’s not a dedicated language for map visualization, whereas this option is built for that purpose.
