Tiles are 256x256 pixels; At the outer most zoom level, 0, the entire world can be rendered in a single map tile. Each zoom level doubles in both dimensions, so a single tile is replaced by 4 tiles when zooming in. This means that about 22 zoom levels are sufficient for most practical purposes.
The OpenStreetMap data primitives are stored and processed in different formats. OpenStreetMap server uses PostgreSQL database, with one table for each data primitive, with individual objects stored as rows. [21] [22] The data structure is defined as part of the OSM API. The current version of the API, v0.6, was released in 2009.
The resolution of 960H depends on whether the equipment is PAL or NTSC based: 960H represents 960 x 576 (PAL) or 960 x 480 (NTSC) pixels. [29] 960H represents an increase in pixels of some 30% over standard D1 resolution, which is 720 x 576 pixels (PAL), or 720 x 480 pixels (NTSC). The increased resolution over D1 comes as a result of a longer ...
Keeping the pixel density of previous models, the iPhone X and 11 Pro introduced a 2436 × 1125 resolution for 15 cm or 5.8 inch screens, while the iPhone XS Max and 11 Pro Max introduced a 2688 × 1242 resolution for 17 cm or 6.5 inch screens (with a notch) all at an aspect ratio of roughly 13∶6 or, for marketing, 19.5∶9.
If the shape has a Wikidata item and the OpenStreetMap shape relation already has a wikidata tag set to that item's QID, you can embed a map of the shape directly onto a Wikipedia article as external data. Use the {} template, setting the |id= parameter to the QID, such as Q88466277. Normally, changes to the route in OpenStreetMap are reflected ...

An image of N pixels height by M pixels wide can have any resolution less than N lines per picture height, or N TV lines. But when the pixel counts are referred to as "resolution", the convention is to describe the pixel resolution with the set of two positive integer numbers, where the first number is the number of pixel columns (width) and ...
The term display resolution is usually used to mean pixel dimensions, the maximum number of pixels in each dimension (e.g. 1920 × 1080), which does not tell anything about the pixel density of the display on which the image is actually formed: resolution properly refers to the pixel density, the number of pixels per unit distance or area, not ...
