Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

It should be understood that the embodiments described are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims.

In the description of the present application, it is to be understood that the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not necessarily used to describe a particular order or sequence, nor are they to be construed as indicating or implying relative importance. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as the case may be. As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The word "if/if" as used herein may be interpreted as "at … …" or "at … …" or "in response to a determination". Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the prior art, when a tower footing topographic map is generated, a complete tower footing topographic map measurement data file needs to be prepared in advance, a general diagram of all tower footing topographic maps is generated according to absolute geographic coordinates, and then each tower footing topographic map is manually rotated by a specific angle according to rules to generate a tower footing topographic map framing diagram; the drawing workload is large, the efficiency is low, and the manual error rate is high; if the tower footing topographic map is generated by directly rotating the tower footing topographic measurement data file by a specific angle, the generated tower footing topographic map is difficult to extract the data such as ground objects, section elevations and the like in the tower footing topographic map because the generated tower footing topographic map is rotated by the specific angle;
