You will learn how to:


Create and edit vector layers


To prevent potential inconsistency between local and cloud project's versions? shapes created in the project locally are not accessible in the cloud while the vector layers created in the cloud are not accessible locally because both objects are editable.


Create vector layer


To create a new vector layer left-click on the Add button in the Workspace pane on the left.


Edit vector layer


To select the layer left-click on it's name in the Workspace pane  on the left.


To change a vector layer name select it in the Workspace pane on the left, open Properties pane on the right and edit the name.

 

To change vector layer children geometries default color select it in the Workspace pane on the left, open Properties pane on the right and select the color. Note that when changing the vector layer color it will be applied to all children geometries.

 

To delete a vector layer select it in the  Workspace pane on the left then left-click on the Delete button next to its label  or press Delete key on the keyboard. Alternatively open the Properties pane on the right and left-click on the Delete button in the top right corner.


To undo vector layer deletion left-click on the Undo button appear on the bottom left side of the window.


Export vector layer


Geometries and its properties are saved in the vector layer, in case you need to use it in a third party application download the vector layer as .geojson file.


To download vector layer as .geojson file select it in the Workspace pane on the left, open Properties pane on the right and left-click on the Download button in the top right corner.


Draw points and measure positions


Draw point


To create a new point activate the Point tool by left-clicking on it's icon in the top right corner of the window and then click on the point of your interest in a 3D scene. When Point tool is activated, it is available to draw new points. To deactivate the Point tool left-click on it's icon in the top right corner of the user interface 


Edit point geometry and appearance


To select the point left-click on it's name in the Workspace pane on the left or left-click on it in a 3D scene.

To edit the existing property, select the property's Name or Value field and edit it, changes are being saved automatically. 


To delete the property, left-click on the Delete button next to the property. To undo property deletion, left-click on the Undo button appear on the bottom left side of the window. 


Measure position


A WGS84 (EPSG::4326) coordinates of current mouse cursor position are available in Coordinates pane on the bottom of the page. 


In case you need to perform precise position measurement - activate the Point tool, draw the desired point and inspect it's WGS84 (EPSG::4326) coordinates in the General properties block of a Properties pane on the right.  Each time you change point position it's coordinates are re-calculated.


Point coordinates are saved in it's properties, in case you need to use them in a third party application you can copy them or download point as .geojson feature.


Export point


To copy point coordinates click on the Copy button on the top right corner of General properties block of the Properties pane on the right.


To download single point as .geojson file select it in the Workspace pane on the left or in a 3D scene, open Properties pane on the right and left-click on the Download button.

When the Polyline tool is active it is available to draw new polyline immediately after finishing the previous.


To deactivate the tool and stop drawing - left-click on the tool icon in the top right corner of the window.


Edit polylines


To select the polyline left-click on it's name in the Workspace pane on the left or left-click on it in a 3D scene. 


To change a polyline name select it in the Workspace pane on the left or in a 3D scene, open Properties pane on the right and edit the name. Alternatively, double click on the polyline's name in the Workspace pane on the left and edit it's name.


To change polyline color select it in the Workspace pane on the left or in a 3D scene, open Properties pane on the right and select the desired color.


To change polyline vertex position select it in a 3D scene and drag to desired position. 

 

To delete a polyline select it in the Workspace pane on the left or in a 3D scene and left-click on the Delete button  or press Delete key on the keyboard. Alternatively select the polyline, open Properties pane on the right and left-click on the Delete button. 


To undo polyline deletion left-click on the Undo button appear on the bottom left side of the window.

Measure length, horizontal length, slope and elevation difference


Each time you create a new polyline or change existing polyline vertices positions it's properties are calculated.  


Polyline properties:

  • Length - a sum of polyline edges length in a 3D space.
  • Horizontal length - a sum of polyline edges length projected onto the plane tangent to ellipsoid in a centroid of polyline vertices.
  • Slope - a slope in percentage between the first vertex and the last vertex of polyline, calculated as an elevation difference between the first vertex and the last vertex of the polyline divided by the horizontal distance first vertex and the last vertex of the polyline, multiplied by 100.   Wikipedia article for reference.
  • Elevation difference - a difference between elevation of the start point and the end point of polyline.


In case you only need to perform measurements but not to save the polyline - activate the Polyline tool, draw the desired polyline, inspect measurement results in the General properties block of a Properties pane on the right, and then right-click or press ESC instead of finishing drawing - the temporary polyline will not be saved into the vector layer.


Export polyline

Measure area and perimeter


Each time you create a new polygon or change existing polygon vertices positions its properties are calculated.  


Polygon properties:

  • Area 2D the area of polygon projected onto the plane tangent to ellipsoid in a centroid of polygon vertices. Most suitable to measure  an area of a land plots.
  • Areathe area of the polygon projected onto the plane best fitting the polygons vertices 3d positions. Most suitable  to measure an area of oblique surfaces like walls and roofs.
  • Perimeter 2D - a sum of polygon edges length projected onto the plane tangent to ellipsoid in a centroid of polygon  vertices. 
  • Perimeter 3D - a sum of polygon edges length in a 3D space .
