| Abstract: | A new data strucure and it's management technique,which is called triangulated irregular network index by triple square grid,is put forward based on the analysis of DTM and interpolating terrain elevation in railway location design.Practical usage validate that it's fast,simple,linear dependent of data amount,suit for the construction of large DTM. |
