Beschreibung
Zusammenfassung:	The invention discloses a custom map and coordinate positioning method based on a mobile terminal. The custom map and coordinate positioning method comprises the steps that a, a plane coordinate of aknown positioning point is obtained and corrected; b, drawing and drawing coordinate correction is carried out, specifically, two plane coordinate points of the upper left corner and the lower right corner of the latitude and longitude network on the drawing is first obtained, the drawing is saved as a user custom map, then the corrected positioning point, that is, the plane projection coordinatepoint of the current position is converted into a screen pixel coordinate point, and the current positioning coordinate point of the known positioning point is drawn in real time in a drawing thread;c, the information data of the position are recorded; and d, the plane projection coordinate of the selected point is displayed, specifically, by using the conversion of the screen pixel point to theplane projection coordinate
