![]() ![]() ![]() It is possible to give a real 3D depth to a top view. The distance between curves (delta altitude), color should be user defined.ģ. Generating altitude contour lines could also help to produce a sensation of depth. The shading intensity is then inversely proportional to |Aij|.Ģ. If |Aij| is between 90° and 0° then the shading is on at point ij. The angle Aij is the angle between v1 and v2ij. Each ground vector v2ij is the surface normal vector pointing upward at point ij One needs to define one 3D vector v1 from the chosen position of the sun to say the center of the map.Ī field of ground normal vectors of ad-hoc density must also be calculated. Hillshade maps already exist but what could be even more useful is a user defined hillshade where it is possible to define the coming direction of the light. The depth information is communicated with a single picture. Would it be a solution to generate some hillshade on top of the view? This is a static method. There are different ways to achieve that result, static methods and dynamic methods.ġ. I love 3D views but what I am missing is a way for my brain to know what are peaks and what are valleys in maps and specially orthophotos. There`s a big difference between what looks nice and what we actually need. Until the challenges with OpenGL API are solved, we should look into different manner to visualise altitude changes on a map. This feature will further solidify Locus Map's position as a leading provider of mapping and navigation solutions in the industry. By following the proposed technical approach, Locus Map can unlock new possibilities for visualization and exploration of geographical data.
