Geograma

Geograma, located in Spain, is formed by a group of enterprises specializing in GeoInformation. GeoInformation encompasses any type of data with a geographic or spatial component.

What is GeoInformation?

The GeoInformation encompasses any type of digital data with a geographic or spatial component.

From satellite imagery to geo-terrestrial photographs, through mapping, socioeconomic data or pedestrian traffic, street, inventory, traffic information, or customer data and market. The wide range of GeoInformation available today allows to optimize management processes and support decision-making in both the public and the private.

Who can use GeoInformation?

Geograma offers specialized services capture, treatment and management of Geoinformation and distributes tailored solutions to industries as diverse as mobile telephony, banking, municipalities or engineering.

Movistar, La Caixa, Yellow Pages, Basque Government, Seville Town Hall, Red Eléctrica of Spain or the Commission's Telecommunications Market are some of the clients who have trusted Geograma to improve processes that incorporate geographic intelligence in their flows I work.

DESTACADO

  • Orthorectified Radar Image (ORI) +

    An ORI is a greyscale image of the earth’s surface that has been corrected to remove geometrical distortions that are a normal part of the imaging process. This product looks similar to a black-and-white aerial photograph. The difference is that, instead of being made of visible light, the radar pulses the ground with “flashes” of radio waves, which then return from ground (or whatever they strike, including buildings and trees) to the antennae to give distance and intensity measurements. The key feature of this product is that it provides a means of viewing the earth’s surface in a way that accentuates features far more than is possible with aerial photography. The radar looks to the side of the aircraft and casts “shadows” that enable users to visually perceive the elevation information in the image—even if they are unfamiliar with the underlying technology.
  • Digital Surface Model (DSM) +

    A DSM is a topographic model of the earth’s surface (canopy) that can be manipulated using a computer. It is comprised of elevation measurements that are laid out on a grid. These measurements are derived from the return signals received by the two radar antennae on the aircraft. The signals bounce off the first surface they strike, making the DSM a representation of any object large enough to be resolved. This includes buildings, vegetation and roads, as well as natural terrain features. The key feature of this product is that it provides a geometrically correct reference frame over which other data layers can be draped. NEXTMap Digital Surface Models are available in 5, 10, 15, and 25 meter post spacings.
  • Digital Terrain Model (DTM) +

    A DTM is a topographic model of the bare earth that can be manipulated using a computer. A DTM has had vegetation, buildings and other cultural features digitally removed—leaving just the underlying terrain. The DTM may not portray the bare earth where obstructions cannot be removed. The key feature of a DTM is that it enables users to infer those terrain characteristics that may be hidden in the DSM. NEXTMap Digital Terrain Models are available in 5, 10, 15, and 25 meter post spacings. NextMap(R) Worl 30 is the first Worldwide, Void-Free DSM. The manufacturer Intermap used over 87 million Lidar Ground Control Points to identify sifnificant vericar errors.
  • Custom Contours +

    A contour layer is a vector-based map layer derived from the bare-earth DTM depicting elevation information for the corresponding terrain. Contours are created on a custom basis and include specifications defined by the customer such as specific contour interval, index contours, etc. Contours are sold as an add-on product with the purchase of the DTM.
