2GIS to your advantage. As we added the card to Apple Watch
 
Apple Watch quickly gained popularity and became the most popular watch in the world, ahead of Rolex and other manufacturers. The idea of ​​creating an application for watches is vital in the office of the 2GIS since 2015.
 
Before us, a full-fledged application with a map on the clock was released only by Apple itself. The Yandex.Map application displays only the traffic jams widgets and the travel time to home and work. Yandex.Navigator, Google Maps, Waze and Maps.Me are not available on the clock at all.
 
In fact, because of the many limitations of the system and the complexity in the development...

Server in the clouds: Project summary

Friends, it's time to sum up our project-competition "Server in the clouds". If someone does not know, we have zapilili fanic gik-project: they made a small server on Raspberry Pi ? screwed to it a GPS tracker and sensors, loaded all this stuff into a balloon and trusted the forces of nature. Where the ball lands, it is known only to the gods of the winds and the patrons of aeronautics, so we invited everyone to put the points on the map - whose points will be closest to the actual landing site, receive "tasty" prizes.

Server in the clouds: we are preparing to launch

Server in the clouds: we are preparing to launchIn post about regatta we mentioned that in August, all contenders will receive a contest with prizes. It's time to rip off integuments veil of secrecy. Once we came up with the idea that the phrase "server in the clouds" can be understood literally. And let's really launch into the sky a working server that can be pinged! At first the idea looked insane, but having twisted it and so much, having discussed it in every way, we still came up with a way to send the server to meet the birds. Already at the end of August, an epochal launch will take place, and for now we are working out the ...

Fitness service again "handed over all appearance" of governments, military and security services

Fitness service again "handed over all appearance" of governments, military and security servicesIn the era of unguided ballistic missiles a proverb was born that "in one funnel the bomb does not fall twice". Since then, ammunition has appeared, with an adjustable flight path, and the proverb began to symbolize the hope that people can learn from other people's mistakes, and twice epic fail for the same scenario can not happen. However, as they say, "there never was such a thing, and again"

Irregular tiles on the surface of procedurally-generated planets

Irregular tiles on the surface of procedurally-generated planetsHere we will consider the method of dividing the spherical surface of a procedurally-generated planet by irregular tiles, and, as a consequence, the division of the ocean and continents into separate sectors (sectors). We assume that the surface of the planet has already been given the structure of land areas with the help of some GIS and it is possible to export vector data to ESRI shapefiles or directly to the PostgreSQL database with the extension PostGIS . The very process of creating sectors is carried out by means of PostGIS.

Shot from the movie "Up" (2009)
 

 
Geodata need a huge number of applications - from navigators to programs reminiscent of an event near a particular place. Therefore, many companies are developing services using location information services (LBS).
 
 
To solve this task, GPS capabilities are not enough: GPS works worse in the premises, and even in open terrain, satellite search sometimes takes a long time. Companies offer different approaches to finding an alternative to this technology. For example, since 200? when ...

Map matching and processing of raw GPS data on an industrial scale

Any measuring instrument, whether analog or digital, shows the result with a certain error and noise. The error of the GPS sensor is determined by the error of the sensor itself and by factors such as: terrain, speed, the number and position of the satellites.
 
In our application is we provide the user with the opportunity to view in detail the routes of his trips. And if you display raw, not filtered data, it turns out that the route does not pass along the road, but through buildings or along the water, some waypoints are very far from neighboring or even missing pieces of the route.
