Description of drawings
Fig. 1 is system flowchart of the present invention.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.
As shown in Figure 1: a kind of method for building up of the highway engineering two dimension office system based on Google earth, the gordian technique in its each step is:
Construction drawing is handled: be the point data collection with the text conversion in the marked graph layer, polygon is carried out closure to be handled, because just can carry out Fill Color after the polygon closure, and not closed polygon can only demonstrate the pattern of lines, can't reflect the pattern of fill color.
Data Format Transform: use third party software that cad data is converted to the form that Oracle Spatial supports, make Geoserver can issue and read map datum.
The coordinate system conversion: the coordinate registration also is in the conversion of coordinate system, its basic aim is that the coordinate conversion with certain point of original coordinate system is the coordinate of these 2 points corresponding in the target-based coordinate system, usually the rectangle registration needs 2 points, linear registration needs 4 points, and the polynomial expression registration needs at least 7 points.In the present invention, by following two stepping row-coordinate registrations:
1) at first determine to need the coordinate points of registration, generally select than the point that is easier to locate, such as certain bar road beginning or end, with the point of crossing of other roads etc., record its coordinate figure.
