Purpose

The PNOA is a cooperative project in which the General State Administration and the Autonomous Communities participate. It began in 2004 with the aim of obtaining digital aerial orthophotographs of the entire Spanish territory, the updating period is fixed, currently 3 years. Its objective is to obtain a homogeneous, continuous and true-to-reality image. They are distributed in COG format and in MTN25 sheet cuts. The maintenance process is continuous.

Specific usage

Aerial photography is the basis for cartography and geographic information in general, land cover, country planning, land registry, forest management, hydrography, etc. Using the same starting photogrammetric data, a geometric and temporal coherence of the cartographic and geographic databases are achieved. The characteristics of the products obtained in the PNOA meet the needs of all the administrations involved.

The orthoimages are available through the PNOA's WMS visualisation services ( https://www.ign.es/wms-inspire/pnoa-ma?) and the PNOA's WMTS tessellation service ( https://www.ign.es/wmts/pnoa-ma). They can also be downloaded from the CNIG Download Centre.

Statement

Orthophotos are generated by orthorectification of the PNOA flight photographs of 2023 with a pixel size of 35 cm for Murcia and 22 cm for Extremadura, Andalucia and Ceuta. The automatic mosaic line tracing method has been used using the ‘minimum radiometric changes’ algorithm with manual editing. The LiDAR DTM is used in which it is updated by manual editing and 3D break lines in areas of significant change. Mesh pitch 5x5 m.

Description

Error medio cuadrático: para Murcia con GSD vuelo de 35 cm es 0,80 m y para Extremadura, Andalucía y C.A. de Ceuta con GSD vuelo de 22 cm es 0,50m.

Error máximo en cualquier punto: para Murcia menor o igual a 1,60 m en el 95% de los casos y no podrá haber ningún punto con un error superior a 3,20; para Extremadura, Andalucia y C.A. de Ceuta menor o igual a 1,00 m en el 95% de los casos y no podrá haber ningún punto con un error superior a 2 m.

Las discrepancias máximas entre ortofotos de fotogramas contiguos son de 2 píxeles de ortofoto y las deformaciones no serán apreciables a la escala 1/2500.
