Reads a hand-curated CSV file and converts it to the same list structure as
gq_registry_read(). Multiple rows per layer_key with a class_field
and class_value produce a classification layer. Single rows produce
simple fill/stroke/mark/label styles.
Arguments
- path
Path to a CSV file with columns: layer_key, type, source_layer, class_field, class_value, fill_color, fill_opacity, stroke_color, stroke_width, stroke_opacity, mark_color, mark_shape, mark_radius, mark_stroke_color, mark_stroke_width, label_color, label_size, label_font, label_halo_color, label_halo_width, label_offset_x, label_offset_y, note.
Value
A list with name, version, source, and layers elements,
compatible with gq_tmap_style(), gq_mapgl_style(), etc.
Examples
path <- system.file("registry", "reg_custom.csv", package = "gq")
reg <- gq_reg_custom(path)
names(reg$layers)
#> [1] "bec_zone" "rivers_poly" "dam" "town"
#> [5] "harvest_area" "planting_site"
# Classified layer (multiple rows per layer_key)
reg$layers$bec_zone$classification$field
#> [1] "ZONE"
names(reg$layers$bec_zone$classification$classes)
#> [1] "SBS" "ESSF" "ICH" "BWBS" "CWH" "MS" "SBPS" "SWB" "AT" "MH"
#> [11] "BG"
# Simple layer (single row)
reg$layers$rivers_poly$fill
#> $color
