Distance analysis plays a crucial role in understanding spatial relationships and patterns within geographic datasets. This presentation introduces the use of QGIS (Quantum GIS), an open-source geographic information system software, for conducting distance analysis. The presentation covers various types of distance analysis, including point-to-point distance, distance matrix, nearest neighbor analysis, and line-of-sight analysis. Each type of analysis is explained, highlighting its applications and benefits. The presentation also outlines the step-by-step process of performing distance analysis in QGIS, from loading data to configuring analysis parameters and interpreting the results. By leveraging the power of QGIS, users can gain valuable insights into proximity relationships and make informed decisions in fields such as urban planning, transportation, and environmental studies.
