Heat Map Sample for WinForms

Description

Heat maps is a technique increasingly used in various fields such in biology and other fields. See http://en.wikipedia.org/wiki/Heat_map. They are also used for displaying areas of webs page most frequently scanned by users. http://csscreme.com/heat-maps/.

At ThinkGeo, we are taking this concept to GIS and applying it to geographic maps. Heat maps are a great way to give the users a visually compelling representation of the distribution and intensity of geographic phenomenon.

Please refer to Wiki for the details.

This sample makes use of the following NuGet Packages

MapSuite 10.0.0

About the Code

ShapeFileFeatureSource featureSource = new ShapeFileFeatureSource("../../data/swineflu.shp"); 

HeatLayer heatLayer = new HeatLayer(featureSource);
//Creates the HeatStyle to set the properties determining the display of the heat map with earth quake data.
//Notice that each point is treated with an intensity depending on the value of the column "other_magn1".
//So, in addition to the density of points location, the value for each point is also going to be counted into account
//for the coloring of the map.
HeatStyle heatStyle = new HeatStyle();
heatStyle.Alpha = 255;
heatStyle.PointRadius = 100; 
heatStyle.PointRadiusUnit = DistanceUnit.Kilometer;
heatStyle.Alpha = 180;
heatStyle.PointIntensity = 10; 
heatStyle.IntensityColumnName = "CONFIRMED";
heatStyle.IntensityRangeStart = 0;
heatStyle.IntensityRangeEnd = 638;

heatLayer.HeatStyle = heatStyle;
