Powered by Windows

Portable Mapper works best with Microsoft Windows 10 or 11.


There are many reasons for using Windows but by far the most important are Design Flexibility and Future Expandability.

In business, time is money. And making small changes here and there can make a huge difference. If you need extra data capturing or a specific tool creating then we can do that for you here at Portable Mapper. We'll just create a small self executing patch for you to download and install. There will be a cost of course, but you can then weigh that cost up against time saved out in the field or back at the office.

Portable Mapper's Ecology & Tree Survey Software uses Windows

It's not that simple with Android or iOS. Every change or patch incurs a cost and up to two weeks approval time after we've submitted it. But the bigger problem is a 'Hot-Fix' Android or iOS patch couldn't be applied to just your version as we can with Windows. This makes Android and iOS very secure but frustratingly inflexible. If you ask your current software provider to make changes they'll probably say no. Ask us and we'll say when do you want it done ?


Add in the ease of integration and synchronising with other Windows devices back at the office and suddenly choosing Windows becomes the most sensible option.


Just one problem. Most tablets are not Microsoft. Things are however changing. Since Microsoft introduced it's Surface Pro and subsequently the Surface Go series, manufacturers who were previously strictly Android have started producing Windows models too. Likewise businesses and IT professionals are starting to make the switch too. Attitudes are changing and with the introduction of Windows 11 could we be seeing the tides change ?
