Primary forest extent, loss and degradation within the Democratic Republic of the Congo (DRC) were quantified from 2000 to 2010 by combining directly mapped forest cover extent and loss data (CARPE) with indirectly mapped forest degradation data (intact forest landscapes, IFL).
Landsat data were used to derive both map inputs, and data from the GLAS (Geoscience Laser Altimetry System) sensor were employed to validate the discrimination of primary intact and primary degraded forests.
Maintaining updated cartographic datasets in such environments is a challenging task.
The purpose of the project was to develop methods to expedite the production of geographic information for municipal planning and land monitoring. The Problem – Motivation for Geo Sat Urban dynamics are induced by such activities as new construction (buildings and roads), demolition of unwanted structures, tree plantings along roads, vacant lots being transformed into urban agricultural sites or green areas becoming parking lots.
Utility of thermal image sharpening for monitoring field-scale evapotranspiration over rainfed and irrigated agricultural regions.
Extending post-classification change detection using semantic similarity metrics to overcome class heterogeneity: A study of 19 U.
In robotic mapping, simultaneous localization and mapping (SLAM) is the computational problem of constructing or updating a map of an unknown environment while simultaneously keeping track of an agent's location within it.
SLAM algorithms are tailored to the available resources, hence not aimed at perfection, but at operational compliance. INTRODUCTION This work was conducted in the framework of project Geo Sat – Methodologies to extract large scale GEOgraphical information from very high resolution SATellite images.
