Earth in Detail

Provides accurate and high-performance geographic surveying products and services


Autonomous aircraft purposely designed and manufactured by XAG, are capable of made photographic surveys of large areas from a central point (2km Radius), since their long-range flights allow a coverage that few companies can achieve. From these surveys, georeferenced orthomosaics HD 3GSM are generated.



A Vegetation Index (VI) is a spectral calculation that is done between two or more bands of the source data designed to enhance the contribution of vegetation properties and allow for comparisons of photosynthetic activity across your area of interest.

The use of vegetation indices such as NDVI, NDRE, SIPI, etc.. from multispectral photography has benefited our clients in the generation of information for improving the management of the production units. The vegetation indices are able to generate information of phenology, as well as map areas with low photosynthetic activity: This has made possible to improve the supervision of the fields. In the same way, vegetation indices have proven to be very important inputs for yield estimates as they complement biomass samplings during the initial stages of the crop.


Digital Surface Model (DSM) represents the MSL elevations of the reflective surfaces of trees, buildings, and other features elevated above the “Bare Earth”.

A digital terrain model (DTM) can be described as a three – dimensional representation of a terrain surface consisting of X, Y, Z coordinates stored in digital form. It includes not only heights and elevations but other geographical elements and natural features such as rivers, ridge lines, etc


3D Modeling is the process of creating a three dimensional computer model which represents a three dimensional object.


3D models are made from points or vertices in 3D space connected by geometric data, such as lines and curves. This forms a wireframe representation which can be displayed with a solid surface through a process called ’rendering’. Textures and images can then be mapped to the surfaces of the 3D model to create ‘visualizations’.
