Terros is an application for both field surveys and land mapping; it is therefore particularly suitable for fields such as agriculture, where it is necessary to collect data on farmers, but also to map their plots.Special advantages of Terros:* Perform mapping either with a Bluetooth GPS device or with the GPS of the mobile device (smartphone and tablet).* Export coordinate files (GPX, KML, etc.) from both mobile and web.* View the mappings made both from the web and mobile.
