Outdoor pedestrian mapping focuses on capturing and representing pedestrian pathways, sidewalks, crosswalks, and other outdoor features such as parks, plazas, and landmarks. The process typically involves the following steps:
- Data Collection
Outdoor pedestrian mapping data is collected using various techniques, including GPS-based mapping, mobile mapping systems, aerial imagery, and satellite imagery. GPS receivers and inertial measurement units (IMUs) are used to capture location coordinates, heading, and other relevant data. - Data Processing
The collected data is processed to create accurate representations of outdoor pedestrian pathways and features. This may involve georeferencing the data to align it with a reference map or coordinate system, removing noise or inaccuracies, and integrating additional information such as street names and addresses. - Mapping and Visualization
The processed data is used to create detailed maps that depict pedestrian pathways, crosswalks, landmarks, and other outdoor features. These maps can be rendered in various formats, such as digital maps for navigation systems, web-based maps, or printed maps for public distribution.
