Raster Analysis Overview

GeoRetina AI offers a comprehensive suite of geospatial analysis capabilities, allowing you to extract valuable insights from both raster (satellite imagery) and vector data through a natural language interface.

Types of Analysis

GRAI supports two main categories of geospatial analysis:

Raster Analysis

Raster analysis involves working with satellite imagery and gridded data to analyze Earth's surface characteristics:

  • Land Use/Land Cover Mapping: Classify surface types using AI models like Google Dynamic World.
  • Urban Heat Island Analysis: Examine temperature variations across urban landscapes.
  • LULC Change Detection: Track changes in land cover over time to identify trends.
  • Vegetation Health: Analyze vegetation indices like NDVI to assess plant health.
  • Flood Mapping: Identify and monitor flooded areas.

Vector Analysis

Vector analysis works with point, line, and polygon features to analyze discrete geographic entities:

  • Feature Querying: Ask questions about infrastructure, boundaries, and geographic objects.
  • Spatial Relationships: Explore how different features relate to each other spatially.
  • Demographic Analysis: Combine census data with geographic boundaries.
  • Routing and Accessibility: Analyze transportation networks and access to services.

The Analysis Workflow

While each type of analysis has its specific parameters and outputs, all geospatial analyses in GRAI follow a similar workflow:

  1. Define your area of interest by drawing a region on the map
  2. Formulate your question in natural language (e.g., "Show me land cover types in this region")
  3. Refine parameters if prompted by the AI (time period, resolution, etc.)
  4. Interpret results displayed on the map and in the insights panel
