integrate_terrain_analysis: Integrate terrain analysis with vector data

In geospatialsuite: Comprehensive Geospatiotemporal Analysis and Multimodal Integration Toolkit

Integrate terrain analysis with vector data

Description

Specialized function for terrain analysis integration. Calculates terrain variables from DEM and extracts values to vector data points/polygons.

Usage

integrate_terrain_analysis(
  vector_data,
  elevation_raster,
  terrain_vars = c("slope", "aspect", "TRI", "TPI", "flowdir"),
  custom_terrain_functions = NULL,
  extraction_method = "simple"
)

Arguments

vector_data	Vector data (points, lines, or polygons)
elevation_raster	Digital elevation model
terrain_vars	Terrain variables to calculate
custom_terrain_functions	Custom terrain analysis functions
extraction_method	Method for extracting terrain values

Value

sf object with terrain attributes

Examples

## Not run: 
# These examples require external data files not included with the package
# Extract terrain variables for study sites
sites_with_terrain <- integrate_terrain_analysis(
  vector_data = "study_sites.shp",
  elevation_raster = "dem.tif",
  terrain_vars = c("slope", "aspect", "TRI", "TPI")
)

# Use custom terrain functions
custom_functions <- list(
  ruggedness = function(sf_data) {
    sf_data$slope * sf_data$TRI
  }
)

terrain_analysis <- integrate_terrain_analysis(
  vector_data = field_boundaries,
  elevation_raster = dem_raster,
  custom_terrain_functions = custom_functions
)

## End(Not run)
