Hi VisAD Community: I have already asked something like this before, but this time I will try to give more information about my problem: I'm tring to plot a contour map inside a 2Ddisplay from a text file (more specific a .MIF file from the MapInfo software). My class is reading the polylines that are in the file and then creating Gridded2DSets for each one, then puting then on a Gridded2DSet array and then into a UnionSet. Just like the rivers.java example. Bill told me I should check how many GriddedSets I was creating but the number is about 400 and there are about 25000 points. I don't think this is so much. When I change from Gridded to Irregular2DSet, the application becomes very faster, but the Irregular2DSet can only plot points. I'm using a IBM-PC 300Mhz and Ram:128Mb running Windows 98. Please, somebody must have used maps on VisAD, and this can't be the way it is. I'm doing something wrong. Maybe I should use a FlatField but I dont know how. An aswer is very important in the moment. It can determine if I can use VisAD or not. Thanks Already Cicero Augusto Wollmann Zandoná cicero@xxxxxxxxxxxxxx
