LeafletMapDataGov

A Leaflet Map for Data.gov county, city, state, international resources

1) Convert csv files to geoJson files. USE -----> https://github.com/mapbox/csv2geojson

2) If the geoJson files lack coordinates, there are resources online for finding point coordinates, polygons, and multipolygons. -http://www.latlong.net/

This is good for finding coordinates for cities

-https://github.com/johan/world.geo.json/tree/master/countries/USA 
#This is good for finding polygon and multipolygon coordinates for US states

3) I personally copied and pasted the coordinates to each json feature, perhaps/probably there is a better way. -https://github.com/mapbox/geojsonhint

This allows you to check/debug geojson files for errors

-https://github.com/tmcw/geojson-join 
#Join a stream of GeoJSON against a dataset.
-https://github.com/mapbox/geojsonio-cli 
#A cli for geojson.io
-https://github.com/tmcw/geojson2dsv 
#Converts GeoJson to CSV
-https://github.com/topojson/topojson

4) You can use this url: http://geojson.io/#map=2/20.0/0.0 to check how your geoJson would look on a map very quickly.

5) After your geoJson is ready, you can use leafletjs to create an interactive map. -http://leafletjs.com/

Highly Recommend checking out their tutorials and Documentation, it is easy to follow and pick up

1)You will need to get map tiles for your map.
