Abstract: Provided are a method for determining drawing data of a map element, an electronic device, and a non-transitory computer-readable storage medium. The specific implementation scheme includes determining a reference point position of a non-link element according to a relationship between the non-link element and adjacent link elements in an electronic map and based on lane edge positions of the adjacent link elements; determining a direction of the non-link element according to the relationship between the non-link element and the adjacent link elements; and determining drawing data of the non-link element according to the reference point position and the direction of the non-link element, where the drawing data is used for drawing and rendering an image of the non-link element in a link when the drawing data is loaded by a map interface.

Abstract: The present disclosure provides a landform map building method and apparatus, an electronic device and a readable storage medium, and relates to the field of image processing technologies. The method for building landform map includes: acquiring a to-be-processed image to obtain a grayscale image of the to-be-processed image; classifying pixels in the grayscale image according to grayscale values to obtain binary images corresponding to different landform categories; extracting image spot contours of image spots in the binary images, and taking the extracted image spot contours as vector graphs to obtain a vector graph set; merging, according to position information, the vector graphs corresponding to a same landform category in the vector graph set, and obtaining a first landform map according to merging results corresponding to different landform categories; and mapping, by using a preset landform type, the vector graphs corresponding to different landform categories in the first landform map, and taking a mapping result as a second landform map.
