Measuring and Drawing Toolbar
Click on the ruler icon in the left side toolbar to open the measuring and drawing toolbar. It will open on the right side of the screen.
...
Point, Line, Circle, Square, and Polygon Tools
To draw a feature on the map, use the point, line, circle, square, or polygon tool from the measuring and drawing toolbar.
...
You can cancel a drawing or measurement in progress by pressing the Esc button on your keyboard.
Selection Tool
The selection tool allows you to select a specific drawing or measurement you’ve created. Simply click on the desired shape to select it. The selected shape will be highlighted in blue and the other shapes will show in the default yellow-orange color.
...
Info Window
The selection tool opens a small info window that shows information for the selected shape. If there is only a single shape on the map, it will be selected by default when the info window is opened. If there are multiple shapes, the desired shape can be selected by clicking on it.
...
Selecting Measuring Units and System
You can use the dropdown menu at the top of the info window to change the measurement units between a variety of options in the imperial and metric systems. Length, area, and slope measurements can be selected independently.
...
The measurement unit options for imperial are feet, yards, miles and acres (for area only). The options for metric are meters, kilometers, and hectares (for area only). The slope options are rise/run, degrees, and percent.
...
Toggle Measurement Values
You can use the checkboxes next to the measurement values in the info window to hide or display the measurement values on the map.
...
Copy Measurement Values
You can copy measurement values for the selected shape directly from the info window.
...
Edit Feature
The edit feature tool allows you to edit a drawn feature that has already been completed.
...
To complete the edits, click on the tool again in the toolbar or press the enter key on your keyboard.
Edit Color
The edit color tool allows you to change the color of the measurements and drawings on the map.
To change the color of the shapes, open the edit color tool, select the desired color, and click Save.
...
Undo Shape
The undo shape tool on the toolbar removes the most recently created drawing.
...
Clear Workspace
The clear workspace button on the toolbar clears all drawings on the screen.
...
Export Layer or Feature
The Export layer or feature tool allows you to export your drawings into the following supported formats:
...
Note that different geometry types cannot be exported into the same shapefile format (for example, polygons and points). If you need to export two types of geometry, select a different data format, or select which geometry type to export. You can also select to export the different geometry types to separate shapefiles if desired.
...
Measuring and Drawing in 2D
In 2D, you can draw and get measurement values for the following:
Points (latitude, longitude, elevation)
Lines (segment length, total length)
Polygons (Rectangle or free polygon) (perimeter, area)
Circles (radius, circumference, area)
2D Points: Elevation
The 2D point tool displays the ground elevation above sea level at a given point. To measure elevation, select the point tool and click on a location on the map. An info box will indicate the elevation and lat/long values for the point.
...
| Info |
|---|
The 2D elevation tool shows you the elevation of the ground above sea level - not the elevation of the feature. Use the 3D elevation tool to see the elevation of a feature itself. |
2D Lines: Segment Length and Total Length
The 2D line tool measures the distance between points, ignoring elevation and obstacles.
...
The length of each segment is displayed, and the total length of all segments appears at the end.
...
2D Polygons: Perimeter and Area
The 2D polygon tool measures the area, perimeter, and side lengths of a polygon, ignoring any elevation changes or obstacles.
...
The length of each segment is displayed, and the perimeter and area values appear in the center of the shape.
...
2D Circles: Radius, Circumference, and Area
The 2D circle tool measures the radius, circumference, and area of a circle, ignoring any elevation changes or obstacles.
...
The radius, circumference, and area values appear in the center of the shape.
...
Measuring and Drawing in 3D
In 3D, you can draw and get measurement values for the following:
...
| Note |
|---|
3D measurements are only available in Urban 3D collections. If you try to use the 3D measuring tools in other 3D datasets such as Legacy collections, they will not work. |
3D Points
Elevation
The 3D point tool displays the elevation above sea level at a given point. To measure elevation, select the point tool and click on a location on the map. An info box will indicate the elevation and lat/long values for the point.
...
| Info |
|---|
The 3D elevation tool shows you the elevation of a feature above sea level - not the ground elevation below the feature. |
Relative Height
The Relative Height tool allows you to measure the height of an object compared to a base point. To do so, ensure you’re in 3D mode, then select the relative heighttool from the measuring and drawing toolbar
...
A good base point is one that is located on a flat, preferably paved, surface. Once a base point is marked, the Viewer will assign a color to the base point to represent it’s accuracy:
A base point showing in green is one that is considered to have good precision.
A base point showing in yellow is one that is considered to have adequate precision. Results will probably be okay, but consider using the undo button and selecting a better base point.
A base point showing in red is one that is considered to have poor precision. Use the undo button and select a better base point to avoid inaccurate results.
...
To set a new base point, clear your measurements using the Clear workspace button on the toolbar, then use the Relative Height tool to mark a new base point and new height points.
3D Lines
Height
The height tool is a special kind of line measurement that shows the height of an object in a plane directly above where the first point is placed. To measure the height of a structure or object, ensure you’re in 3D mode, then select the heighttool from the measuring and drawing toolbar. Start at the bottom, using a single left-click to begin measuring and double-click to mark the top. You can also start the measurement at the top of the object and measure height from the top down.
...
| Info |
|---|
Tip: When measuring the height of structures, line up the measuring tool with the base and edge of the structure to get more accurate measurements. |
Length and Slope/Pitch
The 3D length tool measures the distance between points, accounting for elevation and obstacles. It also calculates the slope/pitch of that line. Draw a 3D line by selecting the line tool, then clicking on each point you’d like to measure between. Double-click the last point to finish the line.
...
The length and slope of each segment is displayed, and the total length of all segments appears at the end.
...
3D Polygons: Perimeter, Area, and Slope/Pitch
The 3D area tool measures the area, perimeter, and side lengths of a polygon, accounting for any elevation changes or obstacles. It also calculates the slope/pitch of the polygon, if all vertices are located in the same plane.
...
The length of each segment is displayed, and the perimeter, area, and slope/pitch values appear in the center of the shape.
...
3D Circles: Radius, Circumference, and Area
The 3D circle tool measures the radius, circumference, and area of a circle, accounting for any elevation changes or obstacles.
