This feature empowers users to create simulation-based models that accurately depict the patterns of sunlight as they fall onto the designated area and evolve over time. Imagine a person is present in a park, and want to understand how sunlight will cast shadows, create highlights, and affect the overall ambiance throughout the day. Using IGiS 3D’s Sunshine Analysis, user can input the geographical details of the park and set a specific date and can dynamically visualise the scenario.
  3. The visual field tool combines GIS data and 3D modelling to offer a highly realistic visualization of CCTV based cameras. It helps to identify their coverage areas and potential obstacles while considering line-of-sight analysis, ensuring optimal coverage with minimal blind spots.
  4. 3D GIS enables better terrain analysis by considering terrain, buildings, and other physical features. Before planning for any kind of construction activity user can take the help IGiS 3D Pruthvi to prepare a simulation modelling based on slope, aspect, height and curvature of the land dynamically to get an idea about the construction’s floor area, if any types of depositional/excavation activates area required etc.
  5. Utilizing IGiS 3D legend creator tool urban planner can generate different theme based maps. Through the analysis and visualization of thematic geo-spatial datasets in 3D environment, planners can approach to urban development precisely.
  6. Urban area growth can be analysed by leveraging time stamp data and employing time series analysis tool within IGiS 3D environment, thus providing valuable insights into the temporal dynamics and spatial patterns of urban development.
