I’m Stephen Donaldson from Geolocarta Technologies Pty Ltd and we have just released a FREE iOS app that is powered by open survey control and digital cadastre data released through various channels, formats and structures. We have developed an intuitive interface and method for almost instant discovery of the most accessible and suitable survey control for the users needed.
You can find links to the available apps through out website http://benchmrk.com.au
We have been working on this for a number of years and am excited to have now release Benchmrk publicly for all to use and take advantage of. Even if you are not a surveyor I encourage you to take a look and let us know where we can improve.
