摘要
分析了三维图传输特点,以直观性、一览性、精确性为目标,尝试在用3D光栅图传输三维度地理空间数据的过程中,采用符号化方法,有效、准确地传输第三维度数据。
To achieve cover all altitude information in 3D grating material maps at one glance and more obvious and more accurate. Analyze the characteristic of transformation occurred in 3D maps. Then,inquire into the methods of symbolic representation of the third dimension data.
