IGIS Tech Notes describe workflows and techniques for using geospatial science and technologies in research and extension. They are works in progress, and we welcome feedback and comments below.

This article introduces a novel method for converting 3D voxel maps, commonly utilized by robots for localization and navigation, into 2D occupancy maps for both autonomous aerial vehicles (AAVs) and ...

In this paper, we propose an automatic algorithm which generates depth map of 2D image in good quality. The depth map is generated by fusing global depth gradient and local depth refinement. Image ...
