Colombia: Estimating and mapping landslides and floods

Location of the Phase II, Eastern Zone Jurisdiction CORANTIOQUIA – COLOMBIA.

UN-SPIDER's Regional Support Office in Colombia (IGAC) has entered the second phase of the project "Estimating and Mapping threats by Landslide and flood events with the use of geospatial technologies."


This project is the result of a joint consulting work of IGAC's Research and Investigation Centre (CIAF-IGAC) and the autonomous regional corporation CORANTIOQUIA. The project will foster collaboration through the participation and coordination of different government agencies. At the same time, since it is a governmental project, it will enhance Colombia’s human and technical resources, generating knowledge and leadership in managing geospatial technologies applications in addition to ensuring sustainability and maintenance of the project.

The main objective of the project is to estimate and map the threats from floods and landslide events within the jurisdiction of CORANTIQUIA by using geospatial technologies. The project will use satellite images, high resolution digital aerial photographs taken recently by IGAC's airplane in the years 2009, 2010 and 2011 as well as aerial photographs captured from previous years to map areas affected by landslide or floods. These maps are created through visual interpretation, digital image processing, spatial analysis and implementation of geographic standards.

A specific methodology for digital image processing was designed. The project also supports knowledge management for the areas affected by the recent rainy season and for future events.
