• Improve performance of frac and weighted_frac for large sets of input polygons

version 0.9.0

• Add frac and weighted_frac summary operations, for summarizing categorical rasters
• Add colname_fun argument to exact_extract, for controlling constructed column names
• Add rasterize_polygons function to rasterize a polygon coverage, assigning cells to polygon with greatest coverage area

version 0.8.2

• Fix incorrect read of raster values for value/weighting raster resolutions enabled in version 0.8.1

version 0.8.1

• Fix incorrect grid compatibility error with certain value and weighting raster resolutions

version 0.8.0

• Eagerly load more data into memory to provide better performance for suboptimally-chunked rasters
• Add grid_compat_tol argument to exact_extract and relax from previously hardcoded default
• Avoid error when include_area = TRUE and polygon does not intersect raster
• Support terra SpatRaster inputs to coverage_fraction
• Produce error instead of incorrect result when processing SpatRaster with duplicate names
• Add coverage_area argument to exact_resample
• Allow use of user-defined summary function in exact_resample
• Allow multi-layer inputs to exact_resample

version 0.7.2

• Fix incorrect coverage fraction calculated for certain sliver-shaped polygons with large coordinate values

version 0.7.1

version 0.6.1

• Fix Solaris build
• Avoid undefined behavior when extracting values for polygon entirely outside raster extent
• Fix incorrect results for GeometryCollections with more than one component (previously sf::st_cast was used to convert these to MultiPolygons, but st_cast only processes the first component.)

version 0.6.0

• Support use of weights in exact_extract R summary functions
• Support SpatialPolygons and SpatialPolygonsDataFrame inputs
• Support exact_resample with mode, minority, variety, median, quantiles
• Add default_value and default_weight arguments to exact_extract
• Add coverage_area argument to exact_extract
• Add summarize_df argument to exact_extract
• Accept weights=‘area’ in exact_extract

version 0.5.1

• Fix bug causing progress bar to jump to 100%
• Fix check for data frame in return from R function in exact_extract to allow for derived data frame types such as tibbles.

version 0.5.0

• Add exact_resample
• Add force_df and full_colnames arguments to exact_extract, to obtain output in a consistent format
• Add include_cols and append_cols arguments to exact_extract for linking pixels values or summarized results to input features
• Add median and quantile summary operations
• Add stack_apply argument to exact_extract to apply an R function individually to each layer in a RasterStack / RasterBrick.
• Support returning a data frame from an R function applied to each polygon, then combining those data frames with dplyr::bind_rows

version 0.4.0

• Add named summary operations for variance, standard deviation, coefficient of variation
• Improve performance, most dramatically for named summary operations on RasterStack or RasterBrick inputs.
• Avoid floating point robustness error when computing stats on certain polygons using different resolution value and weighting rasters.

version 0.3.0

• Add include_cell argument to exact_extract (Michael Sumner)
• Fix error thrown by exact_extract when a polygon is partially outside the extent of the value raster but fully within the extent of the weighting raster.
• Avoid error when processing polygons with a Z dimension on GEOS 3.6
• Support sfc_GEOMETRY inputs if all features are polygonal

version 0.2.1

• Fix incorrect results for some polygons that exactly follow boundaries of raster grid cells
• Update tests for compatibility with sf >= 0.9.0

version 0.2.0

• Add weighted mean and weighted sum operations to summarize one raster using the values of another (e.g., population-weighted mean temperature)
• Support use of named summary options on RasterStack and RasterBrick inputs (reduces verbosity, improves performance)
• Fix memory leak in CPP_coverage_fraction

version 0.1.2

• Generate zero-row data frame for polygons not intersecting the raster

version 0.1.1

• Attempt to revert to static linking against GEOS if dynamic linking fails
• Avoid undefined behavior when calling exact_extract on polygon that does not intersect raster.

version 0.1.0

• Initial release to CRAN
