Abstract :
Isoline maps are the combination of data and graphics. Spatial distribution of geographical objects and the interrelationship of geographical elements can both be shown in isoline maps. Grid a large quantity of discrete geophysical and geochemical data by using improved inverse distance weighted averaged method. Then calculate equivalent points and trace the isoline with the algorithm of rectangular grids. In order to help users to analyze and understand the distribution of coal data easily, isoline maps are shown in form of legend and digital elevation model of corresponding dataset.
