OpenStreetMap vs Valhalla: What are the differences?
Introduction
OpenStreetMap (OSM) and Valhalla are two different mapping technologies that offer unique features and functionalities. Understanding the key differences between these two can help in choosing the right mapping solution for specific needs. This document highlights six significant differences between OpenStreetMap and Valhalla.
-
Data Source: OpenStreetMap is a community-driven project that allows users to contribute and edit geographic data. It relies on the efforts of individual contributors to gather, verify, and update data. Valhalla, on the other hand, utilizes data from various sources, including OpenStreetMap, to create its own database.
-
Routing and Navigation: OpenStreetMap provides routing and navigation information based on the available road network and transportation infrastructure. Valhalla, however, goes beyond basic routing and offers advanced features like multimodal routing (incorporating public transit, cycling, walking, etc.), time-based restrictions, and customizable routing profiles.
-
Geocoding: OpenStreetMap provides geocoding capabilities, allowing users to convert addresses or place names into geographic coordinates (latitude and longitude). Valhalla also includes geocoding functionality but offers additional features like reverse geocoding (converting coordinates into addresses) and advanced search capabilities.
-
Offline Accessibility: OpenStreetMap can be downloaded and used offline, with offline maps and routing data available for various devices and platforms. Valhalla also supports offline usage, enabling users to download map data and route information for offline navigation. However, this functionality may require additional setup and configuration.
-
API and Integration: OpenStreetMap provides a comprehensive API (Application Programming Interface) that allows developers to access and interact with its data. It is widely used and supported by numerous applications and services. Valhalla also offers an API but focuses more on providing a specialized routing and navigation engine that can be integrated into applications and platforms.
-
Customization and Extensions: OpenStreetMap is highly customizable, allowing users to add new data layers, tags, and map styles to fit specific requirements. It offers extensive tagging schemes that enable the representation of various attributes and features on the map. Valhalla, while utilizing OpenStreetMap data, does not provide the same level of customization. It primarily focuses on providing powerful routing and navigation capabilities.
In summary, OpenStreetMap is a community-driven mapping project with a wide range of contributions, offering extensive customization and support. Valhalla, on the other hand, leverages various data sources, provides advanced routing and navigation features, and offers offline accessibility while focusing on specialized use cases.
