svgis 0.3.5

Draw geodata in SVG

SVGIS

Create SVG drawings from vector geodata files (SHP, geoJSON, etc).

SVGIS is good for: creating small multiples, combining lots of datasets in a sensible projections, and drawing maps with basic styles based on classes in the source data.

svgis draw input.shp -o out.svg
svgis draw --project utm south_dakota.shp north_dakota.geojson -o dakota.svg
svgis draw --style my.css england.shp scotland.shp wales.shp -o great_britain.svg

Install

Requires fiona, which in turn requires GDAL.

Before installing, run the following on OS X: brew install gdal. On Linux: sudo apt-get -qq install libgdal1-dev.

Then:

pip install svgis

An additional feature is available if you want to download more prerequisites:

# Clip output shapes to the bounding box (smaller files)
brew install geos # os x
sudo yum/apt-get geos # linux
pip install svgis[clip]

Command line tools

The svgis command line tool has several commands: bounds, draw, project, scale and style. svgis scale and svgis style will add a scaling factor or CSS style to an existing SVG file. svgis project is a utility for determining what projection svgis draw will (optionally) generate for given bounding boxes. svgis bounds returns the bounding box for a layer in a given projection. Read the docs for complete information on these commands and their options.

Examples

Draw the outline of the contiguous United States, projected in Albers:

curl -O http://www2.census.gov/geo/tiger/GENZ2014/shp/cb_2014_us_nation_20m.zip
unzip cb_2014_us_nation_20m.zip
svgis draw --project EPSG:5070 --scale 1000 --bounds -124 20.5 -64 49 cb_2014_us_nation_20m.shp -o us.svg

The next two examples use the Natural Earth admin-0 data set.

Draw upper income countries in green, low-income countries in blue:

/* style.css */
.income_grp_5_Low_income {
    fill: blue
}
.income_grp_3_Upper_middle_income {
    fill: green
}

svgis draw --style style.css --class-fields income_grp ne_110m_admin_0_countries.shp -o out.svg

Draw national boundaries in the Europe using an Albers projection, simplifying the output polygons, and draw Germany in purple. `svgis draw \ --project EPSG:102013 \ --scale 1000 \ --simplify 0.10 \ --style ".Germany { fill: purple }" \ --class-fields name \ --bounds -10 30 40 65 \ ne_110m_admin_0_countries.shp \ -o out.svg
