Online Shapefile to GeoJSON Converter
Online Shapefile to GeoJSON converter
Most geographical data seems to be stored in shapefiles, a popular geospatial vector data format. It would be nice to have an online converter that would run in the browser, using HTML5 and simply let you drop shapefile and get GeoJSON. Then I could use d3 to do cool things with maps like this example of rendering a globe with different projections.
So, where do you find shapefile map data? I have found some pretty good shapefiles at US Census Bureau, DIVA-GIS, and Natural Earth Data. D-Maps is also really great but it offers maps in SVG format. In terms of SVG, there is also a lot of blank maps on Wikipedia.
Update: I have tested this with various shapefiles so if you cannot get it to work, please make sure to leave a reference to your files in the comment (this way I can take a look).
If you are interested in learning more about TopoJSON, I think this example and article shows the benefits of that extension to GeoJSON.
Recently, I stumbled across File Bakery which lets you convert a zipped ESRI Shapefile or MS Access .accdb/.mdb file into CSV. Also, here is another Python based Shapefile to GeoJSON converter. Check it out.
