Staking Out

a. Point Stakeout

1. After a field operator has conducted a survey, the points collected can be staked out to verify the accuracy of the coordinate data.
2. To stake out a point, tap on the Tools button in the top right corner and select the Stake Out button. Then, choose the point you wish to stake out.
3. A stake-out window will open, displaying your current location along with a direction line to guide you to the destination point.
4. The stake-out window will provide various parameters, including Easting Change, Northing Change, Distance, Elevation Difference, HDOP, and VDOP. A compass will also be displayed to help you navigate toward the destination point.
5. As you approach the destination, it will be indicated by a 30 cm circle, with a smaller 5 cm circle at the center. When you are within the 5 cm circle, the app will announce "Staked out" and present an Add Point button. Tap on Add Point and then Measure to save the staked point.
6. Alternatively, you can stake out a point by selecting it on the map and tapping Stake Out.

b. Line Stakeout

1. To stake out a line, select the line on the map or choose it from the list of lines.
2. Tap on the Stake Out button. A dialog will appear asking the points interval. Enter the interval as per your requirement and click on Continue Button.
3. A line stake-out map will open, similar to the point stake-out map. However, instead of a point, the map will display a red line with its initial point highlighted.
4. Navigate to the initial point of the line and stake it out. After staking out the initial point, the map will update to show the next point, located at specified interval from the initial point along the line.
5. Continue this process until you reach the end of the line. As you stake out points along its length, the line will gradually change to green.
6. After staking out the final point, a button will appear to save the line. Tap it to save the staked line.

Base Shift

If a base shift occurs, you can calculate the shift from known points and apply it within the survey.

1. Tap on the Tools menu and select the Base Shift option.
2. From the list of points, choose a known point and then select the corresponding base-shifted point.
3. Click on the Calculate Base Shift button. The app will compute the base shift and display the difference value in a pop-up window.
4. To apply this difference as the base shift within the survey, click on the Set Base Shift button.

Dividing a Line into Equal Sections

The Airace One Mobile App allows you to divide a line between two points into equal segments, adding points at specified intervals along the line.

1. To divide a line, navigate to the Tools menu and select the Divide Line option. A pop-up will appear displaying a list of points. Choose any two points and click on the Split Line button.
2. A map will display the line connecting the selected points. After verifying the points, proceed by clicking on the Divide Line button.
3. A new pop-up will prompt you to specify the division distance in meters or feet. Enter the desired distance and click on the Divide Line button.
4. The app will divide the specified line into equal segments based on the entered distance.
5. Finally, click the Save Data button to save the line and the newly created points to the survey. These points can later be staked out by selecting them and choosing the Stake Out option.

Dividing an Area

The app also enables the division of a polygon into smaller sub-polygons of a specified area.

1. To divide a polygon, go to the Tools menu and select the Area Divide option. Choose the desired polygon from the list.

3. After selecting the side, click on the Divide Polygon button and enter the desired area for the sub-polygon. Click on the Divide Area button to proceed.
4. The app will process the polygon and create a sub-polygon with intersecting points. The area of both the main and sub-polygons will be displayed. The intersecting points and sub-polygon will automatically be saved to the survey.

Coordinate Geometry (COGO) Functionalities

The Airace One Mobile App includes a range of Coordinate Geometry (COGO) tools to assist users in analyzing and working with survey points on-site.

1. To access the COGO functionalities, tap on the COGO button in the Tools menu and select the required option.
2. The following COGO functionalities are available in the app:
   • Two Points: Calculate Azimuth, Horizontal Distance, Vertical Distance, Total Distance, and errors between two points. Select the two points and click on Compute to obtain the results.
   • Point to Line: Calculate the minimum distance from a point to a line defined by two points. Select point P and line vertices A and B, then click on Compute to calculate the distance.
   • Offset Point: Determine the coordinates of point P using the coordinates of a reference point A, the azimuth angle between A and P, and the horizontal and vertical distances between A and P. Enter the required values and click on Compute to obtain the coordinates of point P.
   • Intersection Point: Determine the intersection point P of two lines AB and CD. Select points A, B, C, and D, then click on Compute to obtain the coordinates of the intersection point.
   • Bisection Point: Calculate the coordinates of a bisection point P given the coordinates of points A, B (intersection), and C, along with the distance between B and P. Enter the required details and click on Compute to obtain the coordinates of the bisection point.
   • Circle Intersection: Find the common intersection point of circles centered on selected points. Choose a minimum of two and a maximum of four points, then draw circles with the chosen points as centers and desired radii. Once the circles are drawn, click on the Intersect Circles button to find the intersection points. The intersecting points can be saved to the survey, or you can view their details and start a stakeout.

Common Issues and Troubleshooting steps

Sr No.	Issue	Remedy
1	CSV file is not importing	To import CSV file properly, make sure it is in correct format as suggested here
2	Importing DXF file is not showing points in the map	Make sure that DXF file contains position data in UTM coordinates and elevation must be Orthometric Height.
3	Point data and measurement are in Feet but required in Meters or vice versa	Change Unit setting to Meter/Feet in Settings Tab.
4	App not showing RTK Fix	Make sure you've connect with NTRIP server to receive RTCM corrections. To connect to NTRIP server, go to Settings Tab and Add a Ntrip Profile then click on Start CORS.
5	Airace GNSS Device is not showing in Bluetooth device list	Make sure you've paired the Airace GNSS Device via Bluetooth first. Once paired successfully, click on Refresh button in the Device Connection page and it will show the Airace GNSS Device. Click on Connect button to get started.
