The draw and measure tool is a tool available to subscribers that allows you to draw lines and take length and area measurements of the image. To see a tutorial on the Drawing and Measuring tool, please click here.
There are a number of ways to turn off the tool. The first is to uncheck the box next to Active Measurement Tool. The tool will also turn off if you click on any of the panning arrows that surround the image viewer. It will also turn off if you zoom in or out. It will also turn off if you try to change imagery or change over to a map. Basically, any function besides measuring inside the viewer will cause the measurement tool to be turned off.
You will begin by clicking on the check box next to Active Measurement Tool to turn the tool on. Make sure that the bubble is next to Distance in the tool box. Using the mouse crosshairs, click on your starting point. Move out to the next point and click again. The tool box will display overall distance, the distance of that particular line segment, the horizontal (or easterly/westerly) distance and the veritical (northern/southern) distance. You may click on as many points as you would like in order to determine overall distance. Once you have reached your final point, double click on that point and the tool will stop measuring. If you only click once, the tool will continue to measure based on the mouse cursor position being the final point. Once you have double clicked, you can begin another distance measurement.
You will begin by clicking on the check box next to Active Measurement Tool to turn the tool on. Click on the bubble next to Area. Click on the first point that you would like to begin your area measurement from. You can continue to click on as many points as you need to define the area. The tool will automatically close in the area by drawing an invisible line from your last point to the initial point for area calculations. The tool will also measure the perimeter by adding up the distance of each of the lines that you have used to define the area and the individual line lengths. Once you are going to put down the last point to define your area, double click on that point to end the measurement. If you do not double click, the tool will continue to measure based on the position of the mouse crosshairs.
There is a drop down menu in the tool box that allows you to select different units of measurements. Some of the units in the area box are linear units. These correspond directly to an area measurement with these units squared. This means that selecting "foot" when the tool is measuring area will correspond to the area being measured in square feet.
Yes, you can change the thickness of the lines prior to drawing them. Simply use the drag down menu labeled Line Width to change the line thickness. You cannot change the thickness of lines that have already been drawn.
Yes, you can purchase an image with your drawings on it. Remember to double-click the last line of the drawing and make sure to preview the image. If the drawing shows up in the preview, it will be on the purchased image. If the drawing is not in the preview, you may need to double-click the last line.
