What are Lines and Polygons?
The Lines and Polygons feature expands your data collection capabilities in Fulcrum, allowing you to capture more detailed spatial information. Instead of being limited to a single point on a map, you can draw lines or create polygons.
Lines and Polygons are stored as GeoJSON and can be downloaded or exported along with other record data.
How to enable Lines and Polygons on an App
In the Web app, enable the 'Advanced Geometry' setting in the App Builder (you can find this under Location Settings). If you don't have permission to edit an app, please contact your org's admin.
How to create and edit geometries
When creating or editing a record, tap the 'Locate' button at the bottom of the screen. You will then see the map with an options panel at the bottom. If a point or geometry already exists, you will see it on the map. To create or edit a point or geometry, tap the button in the options panel.
Creating a Point
To create a Point, position the map under the crosshair to the desired location and tap the 'Add Point' button then tap 'Done' (iOS) or 'Save' (Android).
Editing a Point
Hovering over a point with the crosshair or tapping it with your finger brings up the Move & Remove choices in the options panel.
Creating a Line
To create a line, select 'Add Point' and move the map so the crosshair is in a new location. Continue to adding points and moving the map as many times as you wish to create the line. When you are satisfied, tap 'Done' (iOS) or 'Save' (Android).
Editing a Line
To Add a point along an existing line, hover over the line with the crosshair. A white dot will appear indicating where the new point will be placed. Tap 'Add Point' to insert a point in the line.
To move an existing point, hover over the point with the crosshair and tap 'Move Point'. You will then be able to move the point to a new location. When you are satisfied, tap 'Add Point' to confirm the new location.
To Remove an existing point in a line, hover over the point and tap 'Remove'.
Creating a Polygon
To create a Polygon, create a line with three or more points and return the crosshair to the original point and tap 'Close Area'.
You will then see the polygon fill with a color.
Editing a Polygon
To add a point to a polygon, hover over a line segment. A white dot will appear indicating where the new point will be placed. Tap 'Add Point' to insert a new point.
To move a point in a polygon, hover over the point and tap 'Move Point'. You will then be able to move the point to a new location.
When you are satisfied, tap 'Add Point' to confirm the new location.
To remove a point from a polygon, hover over the point and tap 'Remove'.
