Photogrammetry

Digital orthophotos represent a high-precision cartographic product obtained by manipulating vertical aerial photographs in a completely digital environment. These orthophotos are equipped with metrics and scale, making them ideal for applications that require precise measurements and detailed terrain analysis.

The process of producing digital orthophotos involves digitizing the flight frames and deforming the image, pixel by pixel, through orthoprojection . This process ensures that each terrain element is located in its true position with a precision that meets the tolerances established for each scale. As a result, digital orthophotos offer an accurate and uniform representation of the Earth’s surface, as if each object had been photographed from its own vertical and at a varying height, but all represented at the same scale.

In addition to digital orthophotos , photogrammetry is also used to produce analog and analytical photogrammetric drawings . This technique allows us to obtain a terrain model from images recorded in the field, using support points to transform the images into reality data. This model provides precise coordinates of the necessary points with high performance and consistent precision that exceeds traditional field measurement methods.

Photogrammetry is a constantly evolving technique with a wide range of emerging applications, such as photogrammetry with video , capturing images with non-visible radiation , its use in art, industry, virtual reality, interactive flights , among others. This demonstrates the continued potential of this technique to transform the way we capture, analyze and use spatial information.
