Description
As part of the project for the provision of data, systems and services for the enhancement of the information system of the Extraordinary Remote Sensing Plan (PST_A), the Autonomous Province of Trento acquired the 4-band orthophotomosaic (RGBI) with a ground resolution of 0.2 m from the aerophotogrammetric survey of the entire surface of the provincial territory.
A Vexcel Imaging GmbH model Ultracam Eagle aerophotogrammetry camera was used to carry out this survey.
The acquisition flights were carried out in the years 2014-2015-2016 (prevailing year 2015) in conditions of absence of cloud cover and under illumination conditions such that the sun's rays had an elevation of no less than 30°.
The 838 ortho mosaicked and cropped images were returned in uncompressed GeoTIFF four-band format (RGBIr) and in compressed ECW format (RGB and CIR), with 0.2m geometric resolution and 8 bit/band radiometric resolution.
The product is available in the Global Reference System (ETRS89) in the realisation ETRF2000 (epoch 2008.0). EPSG code: 6707.
A WebGIS using ESRI technology (ArcGIS Online - AGOL) was created for consulting and downloading the data.
In this application it is only possible to download the RGB ortho images in ECW compressed format.
An OGC interoperability service (WMS service) was realised to access the entire orthophotos at the following address (URL):
