Impervious surface mapping with Quickbird imagery.
This research selects two study areas with different urban developments, sizes, and spatial patterns to explore the suitable methods for mapping impervious surface distribution using Quickbird imagery. The selected methods include per-pixel based supervised classification, segmentation-based classification, and a hybrid method. A comparative analysis of the results indicates that per-pixel base...
متن کاملSubpixel Impervious Surface Mapping
Identified by the EPA as the leading threat to surface water quality in the United States, nonpoint source (NPS) pollution is channeled into rivers and streams via impervious surfaces. Impervious surfaces are anthropogenic features, such as roads, buildings, and parking lots, through which water cannot infiltrate into the soil. Research from the past 15 years shows a consistent, inverse relatio...
متن کاملSeasonal Sensitivity Analysis of Impervious Surface Estimation with Satellite Imagery
Numerous approaches have been developed to quantify the distribution of impervious surfaces using remote sensing technologies. Most of these approaches have been applied to data from a single time period, typically in the summer season (June to September). Presently, it is not clear whether there is an optimal time for impervious surface estimation with these methods. In this paper, the seasona...
متن کاملImpervious surface mapping in Southern Norway
* Corresponding author. Abstract – Impervious surfaces are mapped by applying regression tree classification on Landsat ETM+ data of Østfold County located in Southern Norway. Reference data consist of high precision polygon vector data of roads, parking lots and buildings for a selected region (Fredrikstad Municipality) within the study area. The output from the classification using the regres...
متن کاملA Modified Normalized Difference Impervious Surface Index (MNDISI) for Automatic Urban Mapping from Landsat Imagery
Impervious surface area (ISA) is a key factor for monitoring urban environment and land development. Automatic mapping of impervious surfaces has attracted growing attention in recent years. Spectral built-up indices are considered promising to map ISA distributions due to their easy, parameter-free implementations. This study explores the potentials of impervious surface indices for ISA mappin...
