Draw and Measure Tool (iOS)

Last Updated: Sep 10, 2018 11:59AM EDT

Avenza Maps features a newly redesigned Draw and Measure tool that allows users to draw and measure lines, areas, and circles.  Unlike the previous tool, which did not allow the saving of areas, the newly redesigned tool allows for the saving of measured areas. 

Accessing the Draw and Measure Tool

  1. Open the desired  map that you want to draw/measure lines or areas on
  2. Tap the Tools icon (three dots in the lower right-hand corner), then tap 'Draw and Measure'
     



Drawing and Measuring a Line

To draw and measure a line:

  1. With the Draw and Measure tool open, pan around the map until the crosshair is centered where you like to create your first point
  2. Once the crosshair is in place, tap anywhere on the map view to create the first vertex
  3. Continue in this fashion until your line is complete.  If you need to undo a point you just made, tap the back arrow on the toolbar to remove the last vertex
  4. While drawing, you will see the line measurements at the top of the screen for the current segment, and a total of all lines
  5. Once satisfied with your line, tap the checkmark on the lower right-hand side to save the line.  It will now be listed in your Map Features list
     



Drawing and Measuring an Area

To draw and measure an area:

  1. With the Draw and Measure tool open, pan around the map until the crosshair is centered where you would like to create your first point
  2. Once the crosshair is in place, tap anywhere on the map view to create the first vertex
  3. Once you have a minimum of 3 vertices (2 lines), tap the Line icon to toggle it to Area.  If you need to undo a point  you just created, tap the back arrow on the lower toolbar to remove the last vertex
  4. When you switch to Area mode, you will the current measurements at the top of the screen for the current area and perimeter of the feature  you are drawing
  5. Once satisfied with the area, tap the checkmark on the lower right-hand side of the toolbar to save.  It will now be listed in your Map Features list




Drawing and Measuring a Circle

To draw and measure a circle:

  1. With the Draw and Measure tool open, pan around the map until the crosshair is centered where you would like to create your first point
  2. Once the crosshair is in place, tap anywhere on the map view to create the first vertex
  3. Once you have 2 vertices (1 line), tap the Circle icon to enable it.  If you need to undo a point you just created, tap the back arrow on the lower toolbar to remove the last vertex
  4. When you switch to Circle mode, you can continue drawing in and out to increase or decrease the size of the circle.  With the Circle mode enabled, you will also see the current measurements at the top of the screen for the current area and perimeter of the feature
  5. Once satisfied with the circle, tap the checkmark on the lower right-hand side to save.  It will now be listed in your Map Features list
     

 

Drawing Using Point-By-Point, or Course and Distance

To draw a feature using Point-By-Point or Course and Distance options:

  1. With the Draw and Measure tool open, pan around the map until the crosshair is centered where you would like to create your first point (Course and Distance only), and long press on the map.  This will display the new options at the top of the screen
  2. The default option is Course and Distance.  To access Point-By-Point, tap the arrow next to the heading
    1. Course and Distance - allows the user to enter the heading and distance they would a line drawn.  This will be drawn from the initial location of the crosshair
    2. Point-By-Point - this does not require the crosshair to be centered on a location and uses known coordinates to draw from point to point
  3. Once you are satisfied with your feature, tap the checkmark to save
