How to access Yandex maps (ZWCAD) - Spatial Manager Blog

Описание

Yandex provides image mapping services as an alternative to similar ones such as Google Maps, OpenStreetMap, etc. Yandex allows users access to tile map servers (XYZ/TMS) for the whole planet but with more diffusion and detail for Eastern European countries

Although Yandex is a global services platform on the web, in this video we will focus on the access and use of the Yandex Maps and their configuration and application in ‘Spatial Manager for ZWCAD’ as user dynamic Background Maps

As mentioned above, this map server uses the XYZ/TMS specifications and protocols similar for example to Google Maps servers, although some differential nuances must be noted:

- There is a server (vec) for images obtained from vectorial documentation and a different one (sat) for satellite images
- Although most XYZ/TMS servers define the maps based on the generic “WGS 84 / Pseudo-Mercator” coordinate system (EPSG:3857), Yandex uses a variant of the Pseudo Mercator system (EPSG:3395), which offers a more precise model for the Eastern Europe area. Thanks to the ability to configure in ‘Spatial Manager for ZWCAD’ the coordinate system in which the XYZ/TMS user maps are defined, you will be able to setup this parameter through the “Advanced options” button

Next you can find some examples of URLs appropriate in order to access the Yandex maps:

- Roadmap (Russian toponyms):
http://vec{01,02,03,04}.maps.yandex.net/tiles?l=map&lang=ru-RU&v=2.26.0&x={x}&y={y}&z={level}
- Roadmap (US English toponyms):
http://vec{01,02,03,04}.maps.yandex.net/tiles?l=map&lang=en-US&v=2.26.0&x={x}&y={y}&z={level}
- Satellite:
http://sat{01,02,03,04}.maps.yandex.net/tiles?l=sat&&v=2.26.0&x={x}&y={y}&z={level}
- Only Roads (which you can Bring to front above of your drawing entities):
http://vec{01,02,03,04}.maps.yandex.net/tiles?l=skl&v=2.26.0&x={x}&y={y}&z={level}

Parameters detail:

- “http://vec” or “http://sat”: The map servers (read above)
- “{01,02,03,04}”: Sub-domains available on these servers (learn more on this Blog post)
- “l=“: Map layer
- “lang=” (optional): Language for the map Toponyms, according to the specifications of the standard two-characters ISO

The video will show you how to deal with Yandex Maps in ‘Spatial Manager for ZWCAD’ (and a little trick to get Hybrid Maps – Satellite + Roads)
