A command line tool to link WKT data in two CSV files based on geographic coordinates

Package Exports

  • csv-wkt-link

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (csv-wkt-link) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

CSV WKT Data Linker

A CLI tool for NodeJS that links properties on two different CSV files with a WKT geography field by determining if a geographic point is within a larger geographic region and then linking the rest of the data.

Link two CSV files by geographic coordinates (WKT format)

Options:
  --version                Show version number                         [boolean]
  -p, --polyfile           CSV file with WKT Polygons and GEOID in the
                           properties
  -q, --polyfileWKTfield   Fieldname for the poly file WKT field (default:
                           geometry)
  -c, --coordinatesfile    GeoJSON with coordinates/points to be given correct
                           GEOID. (If it has polygons, the centroid will be
                           used)
  -k, --pointfileWKTfield  Fieldname for the point file WKT field (default:
                           geometry)
  -f, --fields             Comma separated fields to match (default: GEOID)
  -r, --reverse            Copy the data from the point to the polygon instead
  -h, --help               Show help                                   [boolean]

Examples:
  npx csv-wkt-link -c example/assets.csv -k geo -p example/neighborhood-associations-geo.csv -q the_geom -f OrgName

  npx csv-wkt-link --coordinatesfile example/assets.csv --pointfileWKTfield geo --polyfile example/neighborhood-associations-geo.csv --polyfileWKTfield the_geom --fields OrgName
