Web mapping definition
Web mapping is the creation of interactive maps that users can access over the internet. It combines geographic information with web technology to give users a map they can easily explore through a web browser. Web mapping plays a key role in many industries — from location services to urban planning.
How web mapping works
- Geographic information is collected from various sources (e.g., satellites and government records).
- Once collected, the data may need to be processed to ensure consistency and reliability (e.g., removing errors).
- Web mapping tools like Google Maps API or Leaflet convert processed data into interactive maps that can be viewed on web pages.
- Users can interact with these maps by zooming, clicking on features for more information, and customizing their map view.
- Web mapping often includes geolocation features that determine a user's location (e.g., through GPS data or the user’s IP address).
- Geographic data changes over time, so web mapping applications regularly update their data to keep it relevant and reflect the most current information.
How is web mapping used?
- Navigation apps like Google Maps and Waze use web mapping to give users real-time directions and traffic updates.
- Real estate apps use web mapping to allow users to look for properties.
- Web mapping is used for environmental reasons (e.g., to track ecosystem changes).
- Emergency workers use web mapping to help coordinate responses to natural disasters.
- Travel websites use web maps for trip planning and finding services.
