Study on stand structure visualization based on GDI

As the premise and foundation conditions of stand growth and management visualization,stand structure visualization is a key part of stand visualization.Considering the particularity of stand structure data,we filter and standardize the necessary factors.To intuitively simulate the spatial and attributive structure of the stand,our objective was to transfer the field coordinates into screen coordinates and to render two-dimensional abridged general view of every single tree one by one.This essay takes GDI + technology as basis and uses C# in.NET Framework to generate two-dimensional spatial structure diagram which can show the stand density,crown density,spatial distribution pattern and so on.Meanwhile,it generates the histogram to reflect the distribution of stand structure attributes and finally achieves the goal of the visualization of stand structure.
