Major Improvements

  - Resolved indices errors and requirements

Working Examples and Sample Data

  - Added built-in sample datasets (~150KB) to inst/extdata/
      - sample_red.rds, sample_nir.rds, sample_blue.rds - Spectral bands
      - sample_green.rds, sample_swir1.rds - Additional bands
      - sample_multiband.rds - Multi-band stack for auto-detection
        examples
      - sample_points.shp - Sample field locations
      - sample_boundary.shp - Study area polygon
      - sample_coordinates.csv - Tabular data with coordinates
  - New download_sample_data() function for accessing sample data
  - New get_sample_data() helper to get file paths
  - New list_sample_datasets() to browse available datasets
  - New load_sample_data() convenience function to load data directly
  - All README examples now work out-of-the-box
  - All vignettes updated with working code using sample data
  - All function examples (.Rd files) updated to use built-in data

Testing Improvements

  - Fixed EVI calculation warnings in test suite
  - Tests now provide all required bands (red, nir, blue) for EVI
  - Separated EVI tests from general vegetation index tests
  - Improved test coverage: 68 → 70+ tests

Documentation Enhancements

  - Created pkgdown website for easy navigation
  - Organized 185 functions into 10 logical categories
  - Comprehensive vignettes rendered and searchable
  - Consistent package naming (geospatialsuite) across all documentation
  - Enhanced function documentation with working examples
  - Fixed encoding issues in vignettes (special characters now display
    correctly)
  - Removed unnecessary preambles from vignettes for cleaner
    presentation

Package Structure

  - Added R/16-data-download.R for data access functions
  - Added sample data infrastructure in inst/extdata/
  - Added _pkgdown.yml for website configuration
  - Improved test utilities and helper functions

Bug Fixes

  - Fixed test warnings related to EVI calculations
  - Improved error handling in edge cases
  - Enhanced validation for spectral band inputs
  - Fixed special character encoding in vignettes and documentation

Documentation

  - All examples now executable without external dependencies
  - Vignettes demonstrate real-world workflows with sample data
  - README provides quick-start guide with working code
  - Function reference organized by category on pkgdown site
  - Improved vignette readability with better structure and formatting
