The orthophoto is a cartographic document that consists of a vertical aerial image which has been rectified in such a way that the same scale is kept in the entire surface of the image, being a geometric representation on scale of the terrestrial surface. It is a orthophoto with a resolution of 250 cm obtained, by generalization techniques, from orthophotos with more resolution. Generally ortophotos of the serie Ortofoto of Catalonia 50 cm are used. The infrared orthophoto (OI-25M) provides information about the infrared area of the electromagnetic spectrum. Shows the combination of IRC bands that correspond to Infrared, Red and Green channels, a combination called "false color".

The orthophoto is a cartographic document that consists of a vertical aerial image which has been rectified in such a way that the same scale is kept in the entire surface of the image, being a geometric representation on scale of the terrestrial surface. It is a orthophoto with a resolution of 25 cm generated from images with a pixel resolution variable according to the zones. The infrared orthophoto (OI-25C) provides information about the infrared area of the electromagnetic spectrum. Shows the combination of IRC bands that correspond to Infrared, Red and Green channels, a combination called "false color".

The orthophoto is a cartographic document that consists of a vertical aerial image which has been rectified in such a way that the same scale is kept in the entire surface of the image, being a geometric representation on scale of the terrestrial surface. It is a orthophoto with a resolution of 50 cm resolution generated by generalization from an orthophoto with more resolution, through pixel aggregation techniques. The infrared orthophoto (OI-5M) provides information about the infrared area of the electromagnetic spectrum. Shows the combination of IRC bands that correspond to Infrared, Red and Green channels, a combination called "false color".

The Atlas focuses on the climatic characterization of Catalonia in the period 1961-1990. This climate period has been established by the World Meteorological Organization as one of the international reference periods for climate series statistics. It consists of thermopluviometric information structured in 32 layers: 18 layers of precipitation (12 of the monthly averages, 4 of the seasonal averages, 1 of the annual average and 1 of the seasonal pluviometric regime) and 14 temperature layers (12 of the monthly averages, 1 of the annual average, and 1 of the annual average thermal amplitude). It is a database with 2D vector information at a scale of 1: 750.000.
