Supporting large-area, sample-based forest inventories with very high spatial resolution satellite imagery
Information needs associated with forest management and reporting requires data with a steadily increasing level of detail and temporal frequency. Remote sensing satellites commonly used for forest monitoring (eg, Landsat, SPOT) typically collect imagery with suffi cient temporal frequency, but lack the requisite spatial and categorical detail for some forest inventory information needs. Aerial...
متن کاملForest Stand Segmentation Using Airborne Lidar Data and Very High Resolution Multispectral Imagery
Forest stands are the basic units for forest inventory and mapping. Stands are large forested areas (e.g., ≥ 2 ha) of homogeneous tree species composition. The accurate delineation of forest stands is usually performed by visual analysis of human operators on very high resolution (VHR) optical images. This work is highly time consuming and should be automated for scalability purposes. In this p...
متن کاملTowards Improving Segmentation of Very High Resolution Satellite Imagery
The continued advancements in satellite sensor technologies have increased the number of objects that can be discriminated within satellite imagery. Effective segmentation of high resolution satellite imagery is currently a hot topic of research. Existing segmentation algorithms and applications contain many parameters and options which require the operator to select a proper set of parameters ...
متن کاملSCANNING THE ISSUE Advances in Very-High-Resolution Remote Sensing
This special issue addresses very-high-resolution (VHR) remote sensing data processing and applications. As a matter of fact, satellite and airborne remote sensing is currently undergoing a technical revolution with the appearance and blooming development of VHR sensors. For these sensors, high resolution can be spectral with hundreds of narrow bands, spatial where the resolution of image pixel...
متن کاملRoad Roundabout Extraction from Very High Resolution Aerial Imagery
Road roundabouts, as a class of road junctions, are generally not explicitly modelled in existing road extraction approaches. This paper presents a new approach for the automatic extraction of roundabouts from aerial imagery through the use of prior knowledge from an existing topographic database. The proposed snake-based approach makes use of ziplock snakes. The external force of the ziplock s...
