Vektoritiloja

Vektoritiloja, also known as vector tiles, are a method of storing and transmitting map data that has gained popularity in modern web mapping applications. Unlike traditional raster tiles, which are static images, vector tiles are composed of geometric shapes and attributes that can be rendered dynamically. This allows for greater flexibility and scalability, as the same vector tile can be rendered at different zoom levels and styles without loss of quality.

Vector tiles are typically encoded in formats such as Mapbox Vector Tiles (MVT) or GeoJSON. They contain a set of features, each with a geometry (point, line, or polygon) and associated attributes. This structure enables efficient data transmission and rendering, as only the necessary data is sent to the client, reducing bandwidth usage and improving load times.

One of the key advantages of vector tiles is their ability to support multiple styles and layers. Since the data is stored as vectors, it can be styled and manipulated on the client side using CSS-like rules or JavaScript libraries. This allows for dynamic styling based on user preferences, data attributes, or real-time updates.

Vector tiles are widely used in web mapping applications due to their efficiency and flexibility. They are supported by popular mapping libraries such as Mapbox GL JS, Leaflet, and OpenLayers, making them accessible to developers. Additionally, vector tiles can be generated from various data sources, including open data initiatives like OpenStreetMap, ensuring a wide range of use cases and applications.
