This module can also be used as a tool to register points / markers which will automatically be stored in a database complete with coordinate data, time of observation, elevation from sea level (premium) and geocoding address (premium). Each marker can be labeled manually with unique label / notes. Marker style can be changed to display ID or notes / label to make the markers easier to recognize.
To perform a simple spatial analysis, the application equiped with Tools to perform & display complex geometry analysis such as triangulation (Delaunay Triangulation), Voronoi Diagrams, Fix Buffers and Convex Hull. These geometries line & polygon can be displayed and hidden according to your wishes, the object will be dynamically change when you add a new marker data on the map.
To save measure data to an external file, there is an Export tool which supports KML, GPX and CSV file formats and stored in Google Drive. Saved GPX files can be displayed again on the map by using the Reference File menu as a static reference file.
