NAME

6       topo2geo - converts TopoJSON objects to GeoJSON features
7

SYNOPSIS

9       topo2geo [options] <[name=]file> ...
10

DESCRIPTION

12       Converts  one or more TopoJSON objects from an input topology to one or
13       more GeoJSON features.  For example, to convert the  “states”  TopoJSON
14       GeometryCollection object in us.json to a GeoJSON feature collection in
15       us-states.json:
16
17           topo2geo states=us-states.json < us.json
18
19       For convenience, you can omit the object name and specify only the file
20       name; the object name will be the basename of the file, with the direc‐
21       tory and extension removed.  For example, to convert the “states” Topo‐
22       JSON  GeometryCollection object in us.json to a GeoJSON feature collec‐
23       tion in states.json:
24
25           topo2geo states.json < us.json

37
38       -i, --in file
39              Specify the input TopoJSON file name.  Defaults to - for stdin.
40
41       -l, --list
42              List  the  names  of the objects in the input topology, and then
