Interpretive Summary: This manual covers information about the new NLEAP GIS 5.0, written in the Java™ programming language with GIS capabilities as provided by embedded NASA World Wind technology. This tool provides users with added functionality for assessment of the effects of management practices on nitrogen losses to the environment across risky landscape and cropping system combinations. These new GIS capabilities using the NASA World Wind technology are more advanced and allow for improved and quicker display and assessment of the effects of management practices on long term nitrogen dynamics and pathways for nitrogen losses such as nitrous oxide (N2O) emissions, nitrate (NO3) leaching, and other loss pathways. This version facilitates the analysis and evaluation of management systems across single fields, multiple fields, sub-regions and regions.

Technical Abstract: The NLEAP GIS 5.0 is written in the Java™ programming language and has GIS capabilities as provided by embedded NASA World Wind technology. NLEAP GIS 5.0 can help users identify hot spots across the landscape and identify management practices that can increase nitrogen use efficiency. A Nitrogen Trading Tool (NTT) analysis can be conducted to determine the potential benefits of implementing best management practices and the quantity of nitrogen savings that could potentially be traded in future air or water quality markets.
