用于缓冲几何图形的fiona cli插件。
fio-buffer的Python项目详细描述
用于并行缓冲几何图形的Fionacli插件。由Shapely提供动力
用法
Usage: fio buffer [OPTIONS] INFILE OUTFILE Geometries can be dilated with a positive distance, eroded with a negative distance, and in some cases cleaned or repaired with a distance of 0. Examples -------- Default settings - buffer geometries in the input CRS: $ fio buffer in.geojson out.geojson --distance 10 Dynamically buffer geometries by a distance stored in the field 'magnitude' and write as GeoJSON: $ fio buffer \ in.shp \ out.geojson \ --driver GeoJSON \ --distance magnitude Read geometries from one CRS, buffer in another, and then write to a third: $ fio buffer in.shp out.shp \ --distance 10\ --buf-crs EPSG:3857 \ --dst-crs EPSG:32618 Control cap style, mitre limit, segment resolution, and join style: $ fio buffer in.geojson out.geojson \ --distance 0.1 \ --res 5\ --cap-style flat \ --join-style mitre \ --mitre-limit 0.1\ Options: --version Show the version and exit. -f, --format, --driver NAME Output driver name. Derived from the input datasource if not given. --cap-style [flat|round|square] Where geometries terminate, use this style. [default: round] --join-style [round|mitre|bevel] Where geometries touch, use this style. [default: round] --res INTEGER Resolution of the buffer around each vertex of the geometry. [default: 16] --mitre-limit FLOAT When using a mitre join, limit the maximum length of the join corner according to this ratio. [default: 5.0] --distance FLOAT|FIELD Buffer distance or field containing distance values. Units match --buf-crs. When buffering with a field, feature's with a null value are unaltered. [required] --src-crs TEXT Specify CRS for input data. Not needed if set in input file. --buf-crs TEXT Perform buffer operations in a different CRS. [default: --src-crs] --dst-crs TEXT Reproject geometries to a different CRS before writing. Must be combined with --buf-crs. [default: --src-crs] --geom-type GEOMTYPE Output layer's geometry type. [default: MultiPolygon] --skip-failures Skip geometries that fail somewhere in the processing pipeline. --jobs CORES Process geometries in parallel across N cores. Feature ID's and order are not preserved if more that 1 cores are used. [default: 1] --help Show this message and exit.
