LOCUS Ltd - ravegeo
RaveGeo is a new technolgy for compressing and streaming digital maps.
RaveGeo dramatically reduces the costs and time associated with storing,
distributing, and using huge geographic vector databases.
This product sheet is also available in . A demo application using the RaveGeo technology is .
|Handling large digital maps is a burden.. |
Distributing geographic information is a difficult task. Dense topographic
maps, detailed road databases, and cadastral datasets are often voluminous
and therefore slow to access, especially over the Internet.
.. made easy with RaveGeo.
RaveGeo compresses this information, making it available with unparalleled
performance, even over wireless networks or over the Internet. RaveGeo
is a new database technology for digital maps, the first multi-resolution
vector format. High compression and fast access make RaveGeo ideal for
everything from workstations to handheld devices.
RaveGeo provides fast and easy access to huge databases and makes intense
operations such as continuous, smooth, animated zooms and scrolls possible.
When using RaveGeo databases of any size or resolution can be zoomed
and panned in real-time over the Internet with almost no delay.
RaveGeo reduces the size of databases by 90-95% with preserved topology
and no loss of information. This means that substantially more geographic
data can be distributed on a CD or in the memory of a small device.
The high compression also makes network access extremely efficient.
Wide Scale Range
Navigation using any large source of information demands details and
overview. RaveGeo's multi-resolution capability makes geographic data
available in a much wider scale range. This makes it possible to access
any area, with any resolution, instantaneously. The multi-resolution
also enables progressive streaming of geodata over the networks.
|From workstations.. |
RaveGeo's capacity for handling gigantic geodatabases has made it the
most exciting mapping technology for the next generation of Command
and Control (C2I) applications. RaveGeo will also take web map services
to new levels of performance.
|..to small devices|
The efficient unpacking algorithms and the small footprint of the RaveGeo
reader make it useful on for example GPS-navigators, chart plotters,
next generation mobile phones and handheld devices. The efficient data
compression is particularly useful for small devices where secondary
memory is often limited.
