MapGlow enables displaying your (vector) geodata as heatmaps via the standard WMS protocol. MapGlow is currently a Python MapScript addition to UMN MapServer (though we 			plan to integrate with other WMS servers like GeoServer as well). 			It intercepts WMS GetMap and GetLegendGraphic requests for heatmap generation 			from MapServer Layer Vector (Point-type) sources when the STYLE(S) parameter 			starts with the magic word "heat". In that case MapGlow will query the MS Layer feature data 			and draw a transparent overlay heatmap. The STYLES parameter also determines 			the parametrization of how the heatmap should be drawn in terms of gradient 			colors and other parameters. MapGlow will delegate processing to the standard MapServer OWS dispatching 			for other requests like GetCapabilities 			or when no STYLE(S) is provided.
