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

SVGIS is great for: creating small multiples, combining lots of datasets in a sensible projection, and drawing styled based on classes in the source data. It's perfect for creating base maps for editing in a drawing program, and its CSS-based styling gives great flexibility for styling.

Requires fiona, which in turn requires GDAL.

See the GDAL docs for install info.

Then:

pip install svgis 

An optional feature of svgis is clipping polygons to a bounding box. This will speed things up if you need to draw only part of a very complex feature.

pip install 'svgis[clip]' 

The svgis command line tool includes several utilities. The most important is svgis draw, which draws SVG maps based on input geodata layers.

Additional commands:

• svgis bounds: get the bounding box for a layer in a given projection
• svgis graticule: create a graticule (grid) within a given bounds
• svgis project: determine what projection svgis draw will (optionally) generate for given bounding box
• svgis scale: change the scale of an existing SVG
• svgis style: add css styles to an existing SVG

Read the docs for complete information on these commands and their options.

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 cb_2014_us_nation_20m.shp --crs EPSG:5070 --scale 1000 --bounds -124 20.5 -64 49 -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 } .ne_110m_lakes { fill: #09d; stroke: none; }

svgis draw --style style.css --class-fields income_grp ne_110m_admin_0_countries.shp ne_110m_lakes.shp -o out.svg 

Draw national boundaries and lakes in Europe using the LAEA Europe projection, simplifying the output polygons, and coloring Germany in purple.

svgis draw ne_110m_admin_0_countries.shp ne_110m_lakes.shp \ --crs EPSG:3035 \  --scale 1000 \  --simplify 90 \  --style '.ne_110m_admin_0_countries { fill: tan } #Germany { fill: purple }' \ --style '.ne_110m_lakes { fill: #09d; stroke: none; }' \  --id-field name \  --bounds -10 30 40 65 \  -o out.svg
