The Agustin Codazzi Geographic Institute (IGAC), host to UN-SPIDER's Regional Support Office in Colombia, successfully ended the fourth version of the International Geomatics Week. The 2013 event focused on "geospatial technologies and management of the territory". The event took place from 30 September to 4 October in Bogota, Colombia.
On 30 September 2013, UN-SPIDER's Regional Support Office in Colombia, IGAC, will kick off the “Geomatic Week 2013” in Bogota, Colombia. The event aims at promoting academic and technological advances leading to the development of technologies, methodologies and applications in the field of Geomatics.
This is event is available for participation on an ongoing basis
This International and Interdisciplinary conference is dedicated to scientific and technical methods of environmental information and communication. Special regard is given to the central role of Geoinformation.

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.
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.

The mission included visits to the Risk Management Secretariat, the Colombian Space Commission, the Agustín Codazzi Geographical Institute (IGAC), the Institute for Hydrology, Meteorology, and Environment Studies (IDEAM), the seismological and volcanological Observatory of the National Research Institute of Geological Mining (INGEOMINAS - today Colombian Geological Service) and the Department of Prevention and Emergency of the District of Bogotá (DPAE - today FOPAE).
To mission allowed UN-SPIDER to advance discussions with IGAC, which is serving as Executive Secretariat to the Colombian Space Commission, regarding the establishment of a Regional Support Office to be operated by IGAC. The mission was also used to establish contact with other government agencies in Colombia that focus their efforts on disaster-risk management and emergencyresponse, as well as to make them aware of the UN-SPIDER programme, its activities and the type of technical advisory support it provides.
UN-SPIDER's Regional Support Office in Colombia, the Agustin Codazzi Geographic Institute (IGAC), is currently researching the application of Remote Sensing techniques and digital image processing to support the generation of geomorphological information and the location and mapping of critical areas for landslides in Colombia.
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.
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.
