Degree Erosion Map of Paipa, Boyacá, Colombia

UN-SPIDER's Regional Support Office in Colombia IGAC (Agustin Codazzi Geographic Institute) is currently working on elaborating approaches of using remote sensing and GIS for monitoring soil erosion. Reducing land degradation is a major issue for the environment and sustainable development in the XXI century. Erosion is the main cause for the degradation of soils and rock in Colombia. Experts estimate that approximately 60% of the country are affected by a meaningful degree of erosion. In consequence, the Ministry of the Environment and Sustainable Development of Colombia (MAVDT) created the “following and monitoring for the land degradation program”.

One of the main goals of the programme consists... read more

UN-SPIDER's Regional Support Office in Colombia, the Agustin Codazzi Geographic Institute (IGAC), is currently researching automatic flooded area extraction. The experts are implementing the Adaboost algorithm, which is a change detection procedure. This algorithm consists in creating a strong classifier that is built from a small group of weak classifiers. IGAC's approach uses the medium, mean and variance filters, each of these calculated using three different windows sizes: 3x3, 5x5, and 7x7. Then the experts calculate the difference-image between the filtered after-flood image and the filtered before-flood image.

The algorithm consists of two parts: The training and the application. In the first part, the algorithm is trained to create a model using the two differences-images and a ground truth image. For the application part, the experts used the differences-images and the model... read more

The Agustin Codazzi Geographic Institute (IGAC), host of UN-SPIDER's Regional Support Office in Colombia, conducted a case study to identify flooded areas in Colombia during the maximum rainfall period of the years 2010-2012. This activity was carried out in order to promote the importance of remote sensing techniques and the application of digital satellite imagery for the extraction of flooded areas. The researchers visualized and monitored the behavior of the phenomenon by visual interpretation of optical and radar sensor data... read more

On June 30th, the volcano Nevado del Ruiz in Colombia erupted causing small volcano-related earthquakes and emitting a column of ash approximately eight kilometers high. But thanks to the Volcano Disaster Assistance Programme (VDAP), it was possible to prevent injuries and limit property damage. The VDAP was established following the disastrous eruption of Nevado del Ruiz volcano in Colombia in 1985, since then it has been working to reduce fatalities and economic losses in countries experiencing a volcano emergency.... read more

The Colombian Agustin Codazzi Geographic Institute - IGAC and their Center of Research and Development of Geographic Information – CIAF, recently did a series of projects based on risk management. One of those was focused on indentifying zones in the process of decertification using optical remote sensing in the Andean dry region of Villa de Leyva (Boyacá), Colombia. For this, the experts analyzed the values of the NDVI (Normalized Difference Vegetation Index) from 60 rasters per month (from January 2006 to December 2010) obtained from a MODIS sensor (Moderate Resolution Imaging Spectroradiometer). Based on the... read more

On June 5th, 2012, the Geographic Institute “Agustin Codazzi” (IGAC) was officially registered as member of the Open Geospatial Consortium (OGC). IGAC acts also as the Colombian Spatial Data Infrastructure (ICDE) coordinator, and is therefore well aware of the importance of participating in the construction of standards and technical guidelines to ensure geographic information interoperability.  Becoming a member of the OGC is important both for the IGAC and the ICDE, because this supports participation in research processes, and the development of related geospatial technology topics, thus encouraging the advancement of new processes framed in the context of interoperability. This also backs the ICDE guidelines for using standards, the promotion of exchange, and access to geographic information,... read more

Advisory Support

Colombia is exposed to a variety of hazards including earthquakes, landslides, debris flows, volcanic eruptions, floods and droughts. This Expert Mission was conducted with the aim of visiting several Government agencies, to hold discussions with the Colombian Space Commission on the establishment of a regional support office in Colombia and to establish better links with the Risk Management Secretariat.

Mission dates: 14/04/2010 to 17/04/2010

Colombia está expuesta a una variedad de amenazas que incluye terremotos, maremotos o tsunamis, erupciones volcánicas, deslizamientos, incendios forestales, inundaciones y sequías. La erupción del Nevado del Ruiz en 1985 derritió la nieve en la cima del cono,desencadenando un flujo de escombros que destruyó la ciudad de Armero,lo que causó la muerte de más de 20,000 de sus habitantes. En contraste,la inundación de Noviembre de 1970 afectó a más de cinco millones de sus habitantes,mientras que la de Abril del 2010 perjudicó a más de dos millones. Esta Misión de Expertos se realizó con el propósito de visitar varias instituciones del Estado,para charlar con la Comisión Colombiana del Espacio sobre el establecimiento de una Oficina Regional de Apoyo en Colombia y para reforzar las relaciones con la Secretaría de Gestión de Riesgos.

Mission dates: 14/04/2010 to 17/04/2010
