Maps

This guide describes the mapping functionality within the Low Emissions Analysis Platform (LEAP), detailing how users can visualize energy and environmental results geographically using MapWinGIS integration.

• LEAP allows the visualization of results on maps, which requires the separate installation of MapWinGIS. The map interface consists of a main map for visualization and navigation, a legend to indicate values associated with colors, and a locator map for a birds-eye view of the full extent.
• Region Maps are available for multi-region areas and can be displayed as gradient maps, bar chart maps, or pie chart maps. Gradient maps use color coding based on categorization methods such as Natural Breaks, Unique Values, Equal Intervals, Equal Count, and Standard Deviation.
• Gridded Maps can be used in both single and multi-region areas to display energy and environmental loading results. Implementing these maps requires enabling the 'Map Results to Grid' option, loading proxy GIS data sets for socioeconomic variables to allocate energy use and emissions, and using the Geography variable for allocation.
• LEAP provides a Split screen view for gridded maps that synchronizes a map with a color-coded table of values. Users can hover over the map while holding the control key to scroll the table to the corresponding grid square and view time trends for that specific square in an adjacent chart.
• Map formatting options include the ability to select background images from internet tile services like Bing and Open Maps, adjust the number of value divisions (linear, equal count, log, and reverse log), and set the transparency of the chart layer from 0-100%.
