ogr2ogr wrapper w/ multiple format support
ogr2ogr enables spatial file conversion and reprojection of spatial data through the use of ogr2ogr (gdal) tool
ogr2ogr requires the command line tool ogr2ogr - gdal install page. It is recommended to use the latest version.
npm install ogr2ogr
ogr2ogr takes either a path, a stream, or a GeoJSON object. The result of the transformation can be consumed via callback or stream:
var ogr2ogr = require'ogr2ogr'var ogr = ogr2ogr'/path/to/spatial/file'ogrexecif er console.errorerconsole.logdatavar ogr2 = ogr2ogr'/path/to/another/spatial/file'ogr2streampipewriteStream
/examples for usage examples and
The goal is for ogr2ogr to support most (if not all) formats your underlying ogr2ogr supports. You can see the progress of that in
It also will:
ogr2ogr takes chainable modifier functions:
var shapefile = ogr2ogr'/path/to/spatial/file.geojson'format'ESRI Shapefile'skipfailuresstreamshapefilepipefscreateWriteStream'/shapefile.zip'
Available options include:
.project(dest, src)- reproject data (defaults to: "ESPG:4326")
.format(fmt)- set output format (defaults to: "GeoJSON")
.timeout(ms)- milliseconds before ogr2ogr is killed (defaults to: 15000)
.skipfailures()- skip failures (continue after failure, skipping failed feature -- by default failures are not skipped)
.options(arr)- array of custom org2ogr arguments (e.g.
.destination(str)- ogr2ogr destination (directly tell ogr2ogr where the output should go, useful for writing to databases)
