Why each point needs a value to creat heatmap? #15

Open AndrewGoal opened 12 years ago

AndrewGoal commented 12 years ago

I want to creat a heatmap to express the density of a set of no value points. For example, I have each tree's longlat, now I want to generate a heat map with acidmap to tell us where is forest and where is desert.

How to do it? Help me, Please!

Hi,

I had the same trouble and I resolved it by this way: You will need a column with a numeric value. All the register will have the same value: 1 The parameters will be: Simplify Method: Grid Renderer: Dense Interpolation: Linear

Hope to resolve your problem!

@jlmurielg Thank you very much! What a pity, I gave up acidmap, I think I'll choose it next time. I have used Oracle MapViewer heatmap http://docs.oracle.com/cd/E15523_01/web.1111/e10145/vis_xml_styles.htm#BABEFHDE
