We will carry out this process in many ways but all geared at demonstrating how to trace out features (points, lines and polygons) on your google satellite imagery and convert these vector layers into shape files. We have about four separate approaches using DNR GPS, ExpertGPS, Arcmap and QGIS.
We demonstrate how to features traced from a google satellite image are saved as kml file and converted to shape files using DNR GPS and ExpertGPS.
You can download ExpertGPS Trial for one week to practise. DNR GPS is freeware.
