| Abstract_FL | Discrete Global Grid(DGG) provides a fundamental environment for global-scale spatial data's organization and management.DGG's encoding scheme,which blocks coordinate transformation between different coordination reference frames and reduces the complexity of spatial analysis,contributes a lot to the multi-scale expression and unified modeling of spatial data.Compared with other kinds of DGGs,Diamond Discrete Global Grid(DDGG) based on icosahedron is beneficial to the spherical spatial data's integration and expression for much better geometric properties.However,its structure seems more complicated than DDGG on octahedron due to its initial diamond's edges cannot fit meridian and parallel.New challenges are posed when it comes to the construction of hierarchical encoding system and mapping relationship with geographic coordinates.On this issue,this paper presents a DDGG's coding system based on the Hilbert curve and designs conversion methods between codes and geographical coordinates.The study results indicate that this encoding system based on the Hilbert curve can express space scale and location information implicitly with the similarity between DDG and planar grid put into practice,and balances efficiency and accuracy of conversion between codes and geographical coordinates in order to support global massive spatial data's modeling,integrated management and all kinds of spatial analysis. |
