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.
