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 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".
