Manipulation and Analysis

GIS uses obtained data for decision-making and planning through advanced manipulation and analysis. 

Techniques like overlaying combine data layers to assess impacts, such as evaluating infrastructure affected by a dammed lake. 

Buffering creates proximity zones around features, aiding site planning by identifying areas near water bodies or hazardous zones.

The least-cost path method calculates efficient routes by considering distance and constraints, making it useful for emergency vehicle routing and evacuation strategies during disasters. 

GIS supports planning evacuation routes, resource allocation, and optimizing shelter locations. 

Statistical spatial analysis evaluates relationships between geographical features using tools like spatial autocorrelation to detect patterns or clustering. 

Businesses apply these techniques for site selection, while geologists use them for resource distribution predictions.

Visual tools, such as color coding and pie charts, effectively represent spatial and attribute data. 

Tailored to various applications, final maps ensure informed decision-making and clear communication of results.
