Coordinator +

Using Coordinator app, you can collect coordinate data from land on whatever coordinate system you want, choosing from defined systems. You can collect GPS coordinates. You can use the app as a GPS tracker. You can view a coordinate data on the map. You can search by longitude/latitude. You can convert an existing coordinate into another coordinate system. You can display circumference and area measurements of some coordinates by opening the file which created before. Also you can measure distance and area for some coordinates which determined manually on the map. You can display a KML file on the map. Coordinator app contains several useful tools for people interested in coordinates, maps and geographic information systems (GIS).
Coordinator offers Cloud Database Functions (creating points, lines & polygons, sharing your layers with teammates, working simultaneously with teammates, working offline and synchronizing, etc), exporting to KML & Excel files, get elevation value of points and so on. You can create your layers and share that layers with your teammates. You can instantaneously see the data which is created by other friends on the map instantaneously.
Besides longitude/latitude, subscribers can find out the altitude value of a point on the map. Subscribers can use the Coordinator Web app. So that you can use the cloud database features of the Coordinator app on the web page on your computer and monitor the data instantly. You can view/track and edit cloud database data on the web page. In this way, you can instantly monitor the data movements made in the mobile app in the field, in the web browser on your computer.
