The user interface of EA-GIS is intuitive and easy to use. On the left side of the window there is a toolbar for creating custom objects. All of GIS geometry is made of 3 simple objects: point, polyline and polygon. To make it simpler for the user to create schemes, standard EA-PSM icons have been used for elements. For example, to create a substation the user would choose the substation button and draw a polygon on the map. Individual coordinates can be adjusted later.
When creating an object, the user has to choose which layer the object will belong to. For convenience, default layers have been created and are selected automatically once the user clicks an element icon in the toolbar.
The toolbar also has a “Measure” pane in which measurement tools can be accessed. The user may measure length or area on the map and the results will be displayed in the bottom left corner of the window.
