Qgis is a great and simple tool that for me does the work.
When it comes to geospatial analysis I use qgis. I love that its so easy to implement this tool since all I have to do is download it online.It is available as a freeware and has very many versions.
I love that it is kept current and updated on the regular to ensure that it stays current and relevant.
It has great tools, menus and icons that address all the needs of incorporating gps data or any other kind of data be it an image fro google earth and exploiting the data to achieve my set agenda. Review collected by and hosted on G2.com.
