Open-source Nonpoint Source Pollution and Erosion Comparison Tool (N-SPECT)

NOAA | Analysis Tool

Open-source Nonpoint Source Pollution and Erosion Comparison Tool (OpenN-SPECT) is a GIS tool that helps conservation practitioners quickly and easily identify land areas that generate high sediment and nonpoint source pollutant loads. This is increasingly important in regions experiencing rapid development and other land use conversions. OpenN-SPECT’s scenario analysis functionality allows people to test the relative effectiveness of different land cover management options on sediment and pollutant yields. Additionally, the impacts of changing climatic regimes can be tested with knowledge of potential changes to soils, precipitation, and land cover. The map-based outputs are easily incorporated into planning documents and are useful visualizations in public forums. Training is available on how to use this tool and information on the training can be found here.  For more training information, contact NOAA Coastal Services Center.
