Voyager-Google Maps/Earth - Avinor Print



Implementation of spatial data - visualization using Google Maps/Google Earth


  

Avinor's Aeronautical Database - ORBIT - contains mostly positioned data. To perform spatial calculations in the database, the data is stored as spatial objects. This allows the use of Oracle Spatial's spatial functions  for  queries like

  • find all obstacles within a radius of 45 km from an airport
  • find crossing routes in airspace
  • find distance and direction
  • construct airspaces
  • find potential obstacles in aerorome or runway areas  

BAIT has assisted Avinor in developing this functionality.

To visualize spatiale data, we have developed web-based user Interfaces based on Google Maps. Positioned aeronautic data in Avinor's aeronautical database can be visualized using Google Maps. We have integrated this Web-based map engine with Oracle, and built a user interface to select data to present on the map. Google's map engine provide acceptable map quality, and possiblilities to attach client data, text, symbols, lines etc, and at the same time zoom/pan on the map and supply with detailed information for each object

The data can also be shown in 3D using Google Earth. This program can in addition with map data show a selected area with aim and direction: Google Earth integrates terrain models with maps providing terrain elevation views.

Obstacles around Gardermoen

The picture displays obstacles surrounding Gardermoen, possibly significant for aeronauthical activities. A 45 km circle around the airport indicate area where special significance rulesapply.

Airspaces

TMA airspaces in Norway

Airspaces and routes

FIR airspaces and RNAV Upper routes are displayed

Approach Obstacles

The image displays approach areas for Gardermoen, and obstacles in these areas.

Detailed information

By clicking one of the displayed symbols detailed information for the object is displayed.

Google Earth - aerodrome

The selections made in Voyager can be exported to Google Earth. Here approach surfaces and obstacles

Approach from east towards Sola

The picture shows approach area from east towards Sola, and significant obstacles in this area

Same data in Google Earth

The same data displayed in Google Earth. Obstacles are placed with correct elevation and a pin down to earth to visualize obstacle height.
