geospatialsuite 0.2.0 (2026-05-08)

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
