Create vector datasets from raster surfaces
Project description
A few basic surface creation routines using (primarily) rasterio, fiona, and shapely
Installation
Install dependencies:
rasteriofionashapelyscipy
Clone this repo:
git clone git@github.com:mapbox/make-surface.git
CD into
make-surfacethen pip install -e .
Alternatively, install straight from GitHub:
pip install -e git+git@github.com:mapbox/make-surface.git#egg=makesurfaceUsage
Takes an input raster, and converts into a stacked shapefile. Sort of like gdal polygonize with more control. Also prints out a cartocss template for stylizing (one style for each class).
Turns this:
Into this:
makesurface <input raster> <output shapefile> [OPTIONS]
Arguments
<input raster>Input single-band raster to class and vectorize<output shapefile>Output shapefile to create - output will be “stacked”, with lower values including areas of higher values
Options
--classfile <TEXT>- Filepath to one-line CSV of manually defined break values;--classes <INTEGER>(default = 10) - Number of sections to vectorize into, OR ‘all’ to vectorize into rounded input values; Ignored if classfile specified;--weight <FLOAT>(default = 1) - parameter to weight classification type; 0 = quantile breaks, 1 = equal interval, anywhere between 0 and 1 weights the classification between the two; Ignored if classfile specified;--smoothing <FLOAT>(default = no smoothing) - optional parameter that defines the upsampling and smoothing prior to classification; If none, no upsampling / smoothing is performed;--nodata <ANY NUMBER OR "min">(default = nodata from metadata) - Manually defined nodata value - can be any number or “min”;--carto(default = none) - Flag to include stdout printing of cartoCSS for each class;--grib2(default = none) - Flag to handle.grib2files with bounds of 0 to 360;--helpShow this message and exit;
