Mô tả dự án

I am looking for a freelancer to help me with my project. The skills required are Python, Geographic data extracted from .dxf file. I am happy to pay a fixed priced and my budget is $250 - $750 USD.

Processing needs to be done for 2 different cases: the .dxf describes a surface in 3d space, or it describes the perimeter of a polygon. The attached .dxf's are an example of both cases.

Given a .dxf that contains a description of a surface in 3d space. Python functions are needed that do the following:

1. Given a point in space x,y,z - return the distance z that the surface lies above or below the point.

2. Given a point in space and an azimuth - return the distance 'd' that the surface intersects on the x,y plane.

If an intersection is not found moving in azimuth direction then the code should look in negative azimuth direction and return a negative distance if an intersection is found.

If an intersection is not found in either direction, the code should throw an exception

Given a .dxf that describes a polygon on a flat plane representing a perimeter. A Python function is needed for the following:

1. Given a point x,y the function returns if the point is inside or outside of the polygon. If the point is outside the polygon, the function returns the heading and distance needed to travel to get from the point x,y to the center of the polygon.
