Invention makes 3D mapping greater correct

a new 3-D mapping model integrates multi-platform satellite tv for pc/aerial imagery and laser scanning statistics to acquire a better accuracy in mapping products with the aid of 26-66% to centimetre level in comparison to the conventional mapping technologies.
the 2 major conventional three-D mapping strategies are photogrammetry the usage of satellite/aerial imagery and laser scanning. the former gives better accuracy in the horizontal route while the latter shows higher accuracy in vertical path. they may produce errors at different tiers and there are generally inconsistences between the mapping products derived from them.
To eliminate facts mistakes and combine the benefits of the prevailing technologies, Prof. Wu Bo on the Hong Kong Polytechnic college (PolyU)'s department of Land Surveying and Geo-Informatics advanced a "Novel integrated three-D Mapping version." Integrating multi-platform satellite/aerial imagery and laser scanning information, the generation significantly improved the accuracy in mapping products through 26-66% to centimetre stage.
The fee of the mapping products produced by means of this model is more or much less similar to the satellite tv for pc imagery. This new era lets in monthly updates and dealing with of big statistics and might cater for the wishes inside the massive information technology. it can be utilized in topographic mapping and 3-D modelling of cities for smart town improvement. as an instance, it's far in particular useful in analysing air flow, visibility and sunlight distribution between buildings.
the discovery gained a Gold Medal and unique merit Award from the Nizhny Novgorod country Technical university, Russia, at the 44th global Exhibition of innovations of Geneva.
