How To convert a kmz file into a Shapefile

How to convert Stream network into Shape file

There are two steps to convert Kmz file into shapefile first on Google Earth second step on Arc GIS.

First of all open Google Earth for your project let’s say you  are interesting to work on River system of an area, if you  are working a on a river system there will be many streams which are feeding the river so you have to add a folder by right click in the table of content so that you have to work in that particular folder all the stream network will be in the same folder.
