| New Orthophoto WMS of 2009 Expedited Northwest Quadrant |
|
It opens to the public a new WMS map service in the central node of the Spatial Data Infrastructure of Andalusia. This is the service Expedited orthophotography maps of Andalusia Northwest Quadrant 2009. An orthophoto is a digital cartographic document which consists of a vertical aerial photography has been orthorectified so that it maintains a uniform scale across the surface of the image, for what constitutes a geometrical representation at the Earth's surface on ortoproyectada area used as a reference. In the present case, it seeks an expedited orthophotography capable of turning the document mapping in a time less than that of obtaining a rigorous orthophoto. This will be used directly targeting method, a pre-existing digital terrain model, an automatic method of tracing tile lines, and automatic color balance. It is therefore an orthophoto can be produced in a relatively short period of time because it takes advantage many existing information and parameters provided by the camera when taking photos. This orthophoto dated 2009 for the northwest quadrant of Andalusia has been developed to 50 cm resolution. Beginning with a digital flight geometric resolution 0.45 meters, with information in RGB, infrared and panchromatic conducted in the spring of 2009, with the digital metric cameras and DMC-0020 DMC-0129, with stereoscopic coverage of the entire area work. To achieve expeditious orthophotography is used, a previous TDM and data from GPS / INS and IMU, and aircraft during flight photogrammetric camera. Finally, it must obtain a geometrically continuous orthophotography of the work area, a geometric resolution of 50 cm and with RGB and infrared information. This paper will be distributed according to the distribution of the MTN 1:10,000 scale. As for the reference system, coordinates the project will be given in UTM projection ETRS89 with the spindle 30 and spindle 29 for those leaves that are in this time. This product has been subjected to quality controls according to specifications provided PNOA07-10. The url to access the service is http://www.ideandalucia.es/wms/ortofoto2009eno? |
