solve the development problem Not much to say, start today's theme, today is mainly about how to convert Shp files to GeoJson, which is easy to implement in QGIS, ArcGIS and other professional software, just a button on the line, this article is to study the story behind this button. This article is encountered in the use of Geotrellis, so still belong to this blog set, of course, the framework is also based on Geotrellis.One, the realization Mode 1.

Simply put, JSON can convert a set of data represented in a JavaScript object into a string, which can then be easily passed between functions, or in an asynchronous application passing a string from a WEB client to a server-side program. The string looks a bit odd, but JavaScript is easy to explain, and JSON can represent a more complex structure than a name/value pair.The JSON syntax is a subset of

Fortunately, there have been predecessors to do this work, really walnuts, posterity, here
