svgis 0.1.2

Draw geodata in SVG

svgis

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

$ svgis draw in.shp -o out.svg
$ svgis draw in.shp in.geojson -o out.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 -y libgdal1-dev.

Command line options

–bounds

Only draw the portion of the input file between latitudes 40 and 41 and longitudes -74 and -73 (roughly the New York City area). Note that coordinates are given as ‘minx miny maxx maxy’.

$ svgis draw --bounds -74 40 -73 41 in.geojson out.svg

–scale

While SVG is a vector format, clients may have trouble handling very large numbers. Use the scale option to scale down the output. Dimensions in the map will be divided by this number (so larger numbers yield smaller coordinates in the output SVG).

$ svgis draw --scale 1000 in.shp -o out.svg

Projections

There are two ways to provide projections. Using both at the same time is unsupported. If the input file doesn’t have an internal projection, SVGIS will assume WGS84.

–epsg

Use this option to provide the EPSG code of a desired projection. The example will draw an svg with EPSG:2908, the New York Long Island state plane projection.

$ svgis draw --epsg 2908 in.shp -o out.svg

–proj4

Use this option to provide a Proj4 string that defines a projection.

$ svgis draw --epsg 2908 in.shp -o out.svg

–utm

Attempt to use a local UTM projection to draw the input geodata.

$ svgis draw --utm in.shp -o out.svg

Style

–style

The style parameter takes either a CSS file or a CSS string.

$ svgis draw --style style.css in.shp -o out.svg
$ svgis draw --style "line { stroke: green; }" in.shp -o out.svg

–padding

Adds a padding around the output image.

$ svgis draw --padding 100 in.shp -o out.svg
