1. , based on the modeling method in the true three-dimensional map of DEM and green road, it is characterized in that, described modeling method comprises the following steps:

  • A, utilize Bigemap Map seized device to download at BigeMap map on intercept the remote sensing base map of appointed area and by the gps data of surveying, base map corrected;

    B, vector quantization is carried out to the key element of base map intercepting appointed area;

    C, in DEM, altitude figures assignment is carried out to the base map of appointed area vector quantization and elevation divide;

    D, make three-dimensional model according to the base map of assignment altitude figures respectively at MapGIS, 3DMAX;

    E, in MapGIS, MapGIS three-dimensional model and 3DMAX three-dimensional model are carried out merging and carry out material and paste;

    F, carry out spatial analysis and attribute query to pasting the three-dimensional model after material;

    G, the map set up on DEM and Lv Dao to be roamed.
