DIGITAL ELEVATION MAPS

This project, developed during the CS480 Fall 2010 course by Michael Carroll, Asma Mannan, and Sagar Mutha, showcases a sophisticated approach to digital elevation mapping using C++, OpenGL, and GLEW on Windows platforms. The team implemented features such as a dynamic level of detail, multitexturing, and proper visual scaling of elevation data sourced from USGS NED. Key components included a terrain parser, geometry generation, and realistic camera movement. The project emphasizes compelling data representation and realistic lighting simulations based on user inputs of latitude and longitude.

Presentation Transcript

  1. DIGITAL ELEVATION MAPS • FALL 2010 • CS480 • Michael Carroll • Asma Mannan • Sagar Mutha

  2. INSPIRATION

  3. CONSTRUCTION • Platform: C++ / OpenGL and GLEW / Windoze • SVN on google code

  4. REQUIREMENTS • Compelling Data • USGS NED • Global Mapper (Converter) • Multitexturing • Movement

  5. PLATFORM & PARTITION • Michael – NED Parser & Converter, Geometry Generation • Asma – Multitexturing • Sagar – Camera Movement

  6. DIFFICULTY • Proper Visual Scaling • Each square degree sized differently • Proper Walking • Downsampling Data Reasonably • Texture mapping

  7. EXTENSIONS • More textures, normal generation • Textures vary with normals, not just elevation • Dynamic LOD / Geometry + Textures • Lat / Long user input • Harsher Shading and Sunlight Simulation/ Date Time

  8. END
