When creating or editing fields in Hecterra, take into account the following restrictions:
This way of creating fields is the most time-consuming.
To add a new field to the map manually, follow the steps below.
Below are the tools available for creating and editing fields on the map.
|Draw field. Use this tool to set the field boundary by adding vertices one after another.|
|Edit contours. Use this tool to change the boundaries of an already drawn field.|
|Drag field. Use this tool to move the field to another location.|
|Cut a hole. Use this tool to 'cut out' sections of uncultivated area (buildings, trees, ponds, etc.).|
|Rotate field. Use this tool to rotate the field by dragging one of its points.|
Area and distance. Use this tool to measure distance and area. The tool is available only after saving the field.
When calculating the area of the field, the height difference (terrain) is not taken into account.
|Select the map.|
|Switch to full-screen mode/return to normal mode.|
|Show field names and areas on the map when zooming in.|
Synchronization is one of the easiest and fastest ways to add fields in Hecterra.
After you click on the button , the system checks Wialon for geofences of the polygon type which are not yet in Hecterra. If there are any, it adds them to the application. Such properties as geofence name, description, and shape are transferred.
You can synchronize all geofences created in the resource, or geofences from certain groups (select the required geofences on the Geofence groups tab).
As a result, new fields are added and the ones synchronized earlier are updated.
The basic principles of field synchronization are:
During the synchronization, the system may find such geofences in Wialon that do not have analogue fields in Hecterra, but their names and descriptions are the same as those of the existing fields. In this case, you can select one of the following options in the synchronization dialogue box: merge such geofences with the fields or create new fields on the basis of the found geofences.
In Hecterra, you can import geofences of the polygon type from KML, KMZ, and SHP files. When importing from SHP, you should use a ZIP file containing SHP, SHX, and DBF files.
To import geofences, click on the button in the upper right corner of the Fields page.
Such properties as geofence name, description, and shape are transferred during import. If the names of the fields are not determined, they receive the name NONAME.
In the import dialog box, the Skip same-name fields option is activated by default. This means that the fields with the same names as the fields in the application are not imported.
