The measuring tools allow you to measure distances, areas, and feature locations on a map or scene. You can draw a line to measure length, a polygon to measure area, or click an individual feature to get measurement information. In 3D, there is an additional tool to measure vertical distances.
Choose your method and upon interacting with the viewer, the results appear in a small window overlaid on the map. You can measure any number of segments in a sequence—each click represents a new starting point from which the next distance is measured. The first click in the view begins a line segment, and the next click ends that segment and begins another. Double-click to finish measuring. A cumulative sum for the distance or area also displays as part of the results. You can copy and paste the results to use in other applications.
Measure on the map
- On the Map tab, in the Inquiry group, click the Measure drop-down arrow.
- Choose a measuring tool and click the map to begin measuring.
- Measure Distance —Click the map to measure the straight-line distance between two or more points. In 3D, you can use this to measure between locations not on the ground. For example, click a window or face of a building, and measure over to another building. The line appears as floating but its endpoints are attached to each building.
- Measure Area —Click the map to draw a polygon shape to measure the area on the ground. You can do geodetic area measurements in a geographic coordinate system (GCS) and planar area measurements in a projected coordinate system (PCS).
In 3D, the area measured is returning the 2D surface area.
- Measure Features —Click a feature to measure its length (line), perimeter and area (polygons and multipatches), or x,y,z location (point features).
- Measure Vertical (3D only)—Click to draw a vertical line to measure height or the difference between two locations. Moving the pointer sideways widens a reference circle at the end of the line to assist identifying the top (or bottom) of the measurement.
- Optionally set units for the feedback results and the measurement mode using the overlay that appears on the view.
- Distance and Area Units—Set the distance and area measurement units. You can select multiple units.
- Mode—Set the interactive measurement type for measuring line distances. Geodesic is the default.
- Press Esc anytime during the sketch if you want to cancel a measure to start over, or press Clear Results to completely clear and reset the measurement results.
Modes available when measuring
The interactive measurement mode drop-down list provides a selection of measurement modes you can use for distance measurements: Geodesic, Planar, Loxodromic, and Great Elliptic.
The shortest line between any two points on the earth's surface on a spheroid (ellipsoid). One use for a geodesic line is when you want to determine the shortest distance between two cities for an airplane's flight path. This is also known as a great circle line if based on a sphere rather than an ellipsoid.
Planar measurement uses 2D Cartesian mathematics to calculate length and area. The option is only available when measuring in a projected coordinate system and the 2D plane of that coordinate system will be used as the basis for the measurements.
A loxodromic distance is a line of constant bearing or azimuth. Great circles are often broken into a series of loxodromes, which simplifies navigation. This is also known as a rhumb line. Unlike geodesic, it is not the shortest distance between two points.
The line on a spheroid (ellipsoid) defined by the intersection at the surface by a plane that passes through the center of the spheroid and the start and endpoints of a segment. This is also known as a great circle when a sphere is used. The great elliptic type allows you to create lines only.
Measure 3D height
In addition to using the Measure Vertical tool, you can measure height by placing the cursor over the feature you want to measure, whether its a building or a mountain. The z-value shown in the coordinate display at the bottom of your view is the measured height. The z-units are determined by the elevation units set for your scene.
Measure distance from view to cursor
Distance to cursor displays the straight line distance from your view position to a location in the view such as a mountain top or the corner of a building. To enable this option, click the Project tab, click Options, choose the Navigation tab, and check Show distance to cursor. This value displays along side the coordinates at the bottom of your view.
The units listed for each Measure tool is derived from the units listed on the Units tab of the Options dialog box. To add a new unit, click <Select Unit Code> and choose from the list of all available units. To remove, format, or make the default, right-click the unit.
