1. Constraints set by different map projections, or by map borders, can be overcome by the computer.

2. Map projection is the basis of cartography.

3. The images were re-projected into an orthographic map projection.

4. This paper introduces the method of map projection transformation.

5. In this paper, a series of lunar map projection formulas are deduced including azimuthal projections,(sentencedict.com/map projection.html) cylindrical projections and conical projections.

6. The expansions of conformal latitude in map projection are studied in this paper.

7. The data integration, based on uniform data format, map projection and coding standard, causes that raster data and vector, and also their correlative data, can be managed and queried compositively .

8. A map projection is any method used in cartography to represent the two-dimensional curved surface of the earth or other body on a plane.

9. According to the selective principle of map projection and Guangxi Regional place and form, the normal secant conic conformal projection of Guangxi Region is designed in this paper.

10. The transformation of map projection is the base for mapping theory and an important component of GIS.

11. This paper presents a new map projection based on the new form of geodetic coordinate system.

12. Then the method and theoretical foundation of map projection transformation is analyzed, and the inverse transformation method to implement the component is selected.

13. Map projection transformation is a new research and application field of mathematical cartography.

14. Every map projection distorts distance, area, shape, direction, or some combination thereof.

15. State the properties of the Mercator and Zenithal Equal-area map projections.

16. Great circle routes plot as straight lines on some map projections such as the Gnomonic.

17. The mercator projection is one of the most used world map projection.

18. Through a user-defined coordinate system, it can switch between screen and actual coordinates and realize map projection, etc.

19. This paper provides a new method for coordinate transformation between these two types and based on Newton's iterative method, which is derived from map projection principle.

20. Maps (on paper or on the screen) are flat surfaces; they require a transformation from the curved surface of the earth to the flat plane: a map projection.

21. The GIS software is mainly applied to the department of Geography Information System. Its coordinate system is closely related with map projection.

22. The mercator projection is one of the most used world map projection. It preserves direction and shapes but distorts size, in an increasing degree away from the equator.

23. As an important part of GIS platform, spatial reference system includes coordinate transformation and map projection, also named as Map projection transformation system.

24. And by integrating the orbital calculation of satellite, coverage and map projection, a simulation platform for satellite orbital prediction is designed.
