# Zoom Controls ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/D7Ayq944a9lbrilyxxq9jqd0hiwoq5msgnc-g-jpeg.jpeg) There are multiple methods available for zooming your map. The first method that can be used is the 2-finger pinch controls. By pinching your fingers together on the screen you can zoom out and by moving your fingers apart you can zoom in. The alternate method is the use of zoom in and zoom out buttons that can be added to the bar along the top right. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/iD8kjairoculrex4xdv1gqutaczehahrkygmq-png.png) The zoom buttons are not shown by default. To enable these buttons check the '**Show zoom buttons**' box under ‘**Settings > Application**’. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/M57qpuhjj7jo1w5uxn2rha24fk8an9ueougfg-png.png) ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/DlMgvqkxojetxyvsimhl7nhbo2sjoexrneyqq-png.png) Independent of these zoom controls is the 'Zoom to full' button, this button does NOT need to be enabled. When pressed the button zooms the map in or out to the maximum size that shows the entire surface grid of the map. # Image Overlays ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/qHZv8myqiroo3lytv0mv50ejdwzf-vx3x6jva-png.png)‘Image overlays’ allows geo-referenced image data to be imported into a field. The image overlay is accessed by pressing the button at the top of the screen (Shown right). **![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/QkRxqhdvmowigdd9eqxc3pvssdpaimiaietug-png.png)Add image** This is the primary method for adding overlay images to the field. When the button is pressed a file window will open to select the desired file. The file types that are currently supported as overlay images are **.KML**** **and **.TIFF**. **Load image from JDOC** Images from the John Deere Operations Center can be downloaded into the image overlay. This is useful for comparing previous data (such as yields) with current survey data. **Delete images** Overlay images can be deleted by unchecking the box next to them and pressing the ‘delete images’ button. This will delete the layer from the available list. **Transparency** Overlay images can be set to be transparent so that layers below them can be seen. Check the box to the left of the layer and then press the transparency button on the right side. **Layers** Pressing on any of the layers will cause it to be displayed over the others. # Choose Mode/Terrain/Layer #### **Mode** **2D View** - By default the map will be displayed in a 2D aerial view. **3D View** - When switching to 3D view the map will show all the terrain as small hills and valleys. In this viewing mode if you press the vertical scale magnifier (shown here) it will increase the exaggeration of these hills and valleys so that they can be more easily identified. The focal point when viewing in 3D can be changed by quickly double tapping on a position.

#### **![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/mQD7k02cfbwoceinmwtmm7xv-ipeirsnk2t0q-png.png)View** When viewing a map you have a variety of display options. #### **Surface** ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/Vlgfm2alezcu3ly9y77mgsdu9qdezzirtiurq-jpeg.jpeg)This refers to the source for the 3D topography and coloring of the map. There are 6 options: **Elevation** - This terrain viewing mode shows the map as the original surface prior to any dirt being moved. Displays the map in a Red to Blue gradient scale with Red being low areas and Blue being high areas. **Design** - This viewing mode shows the design that has been applied. This is the surface that you are attempting to reach at the end of the dirt moving process. Has the same color scheme as Elevation. **Cut/Fill** - Shows where the design will be taking dirt from and where it will be putting it. Coloring of this layer depends on the current Cut/Fill color scheme (Settings > Application). **As applied** - Displaying the map using this method shows changes as they occur. It shows a real-time representation of progress as work progresses. Has the same color scheme as Elevation. This terrain is only available if ‘**As Applied**’ mapping has been enabled in the machine tab of ‘**Settings**’. **As Cut/Fill** - Shows where the design will be taking dirt from and where it will be putting it. Coloring of this layer depends on the current Cut/Fill color scheme (Settings > Application). **Pass Count** - This layer displays how many passes you have done over an area. This layer is only available once pass count tracking has been enabled in Settings > Machine:![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/xKih4-ngk659mpypfn2sefmf5yjdjxpn7yywa-png.png) #### **Layers** **Various defined layers can be turned on and off here. This includes the current surface (see above), depressions, drains, linework, and overlays such as KML that have been loaded. The buttons at the top allow you to load and clear layers, and beside each layer is a transparency toggle button. Click the button to change its transparency.** **![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/TeCtwwn1pdkjnfainohxhov-jdh7zyxwbyspg-png.png)** **NOTE: The depressions layer is not shown if the project only has drains (and no elevation surface).** # GPS Data ### ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/tEF1ozxdksmzoi4wjnb7lccdo4dqiujumjpew-png.png) ### In the lower right corner of the screen is the GPS information button. It displays the latitude and longitude of your current position as well as your current heading. TIP: Right clicking (press and hold) on this button will reveal a context menu with the option to display coordinates in UTM format. When you press this button the ‘GPS Info’ window will open with more detailed GPS information. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/hwRf7r6qrru2iurxdcwgdfvze5kmemjijroda-png.png) This window provides the following information: - **Serial port parameters**: displays the current settings for the com port and baud rate that is being used. There are flashing arrows which indicate that the software is sending and receiving information. - **Warning Thresholds**: used to set limits for certain parameters. When these thresholds are being approached the borders of the screen will flash orange, once any of the thresholds have been exceeded or connection to GPS is cut the borders of the screen will flash red. - **Output**: shows all the GPS information currently being received. **Serial port parameters** ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/PAhvfdrdmpoteveimu4p71tgyvjyoz51dnyva-png.png)**Com port**: The Com port # is assigned by the adapter. In the drop down box you can find all available com ports. It is important that this is set to the serial port that is physically attached via cable to the iGrade™ Application Controller. Diagnostic information about current serial ports can be found in the Windows Device Manager. One way of accessing this Windows tool is via the button in bottom left of ‘Settings > GPS’ . ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/Cz6le-nvs-4a1gbrebuzup0nog5mfuckakr3w-png.png) **Baud rate**: The speed at which the system talks to iGrade™. It is important that this matches the iGrade™ settings or the T3RRA software will not be able to talk to iGrade™. We recommend setting the baud rate to 38400 when connected to iGrade v1. If connected to iGrade™ v2 we recommend setting the baud rate to 115200 with **NMEA Message Type** set to “All”. **Warning Thresholds** ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/vdElc-g0gijblg1c-ep-b8l8ofkbkcwdy8f9g-png.png)**Idle timeout**: If no GPS messages have been received in this time period an error warning will show. **RTK Timeout**: This monitors the time since the last good RTK correction packet was received. It should not normally be set above 10-20sec. **Max VDOP**: Vertical Dilution of Precision is a measure of the altitude accuracy. For the most accurate implementation you will want this value as low as possible however setting lower than 2 may cause interruptions in the use of T3RRA software. **Min Satellite Count**: Sets how few satellites the GPS needs to see before a warning is shown. **Output** ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/IWOtrcmdgum-qtiht66scjm0l85mpwbwk-kyw-png.png) **Current & Raw GPS Data**: Current displays the current position data for the receiver, while Raw GPS Data will display all the messages that are coming in. **Lat & Lon**: Your current location coordinates (latitude and longitude). **Altitude**: Your current height (Displayed in chosen measurement format) above sea level. **Num Sats**: The number of satellites that your GPS is currently tracking. This is linked to the Min Satellite Count in Warning thresholds and provides an error if this number drops below what is set there. **Fix**: The type of position solution calculated. **Time**: The current GPS time. **Last Correction**: Time since receiving the last differential correction message from the base station. Should be as low as possible for the most accurate readings. It is linked to the RTK Timeout in Warning thresholds and will provide an error if it exceeds that time limit. **VDOP**: Vertical Dilution of Precision. If this number exceeds the value in the Max VDOP in warning thresholds it will show an error. # Markers ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/6UAv46xrsliqggjidbocwygkhccx7gu4emdpq-png.png)Markers on designs allow for setting points of interest at user-selected locations. This includes using a marker as a benchmark “control point” location in the design. To use a marker as a Benchmark location, refer to ‘**Set Zero using a marker**’ in the Implementation section of this manual. **Set marker** - use this tool to set a marker on the map. Markers are always placed at the current location. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/B6uaozgmmrooe2rzkcdjjjxkvsncrtzgc20ug-png.png)When a new marker is created a window will appear allowing a name for the marker to be entered. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/MJAqa83-ezbzf-gjs0btzpiakmlqrvn-eqg-png.png)**Edit Marker** - this opens a window that allows you to select any marker on the map and edit it. The ‘Edit Marker’ button will open the below window allowing you to see the information of each marker that has been placed including heading, distance and height of the marker relative to your current position. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/PMk6iym8mprymcwlgoivantos9vnzet-eai7a-png.png)Pressing the button next to the marker name will let you change the name of the marker. The buttons at the bottom of the window allow you to select all the markers, delete the currently selected markers, export the currently selected markers and close the window. # Start, Pause and Stop controls ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/B3Y3s4qz-fll0hy6jtjutzwshvametdzogiq-png.png)![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/qEF9ka9fbteaoykc1b05zr395p3z5imu2x7ka-png.png)In the Surveying and Implementation screens the ‘**Start**’, ‘**Pause**’, and ‘**Stop**’ buttons are used to control the beginning and ending of the relevant activities. These buttons do have slightly different functions depending on when they are used. **Normal function**: During normal function these buttons will act in the following way. ‘**Start**’ will begin the system either surveying data or implementing a design. It will also start logging path counts (if enabled). The title of the button will reflect which action it will start. ‘**Pause**’ is only applicable to Surveying. The use of the pause button in surveying is to allow you to continue a path after moving around obstacles. For example surveying a drain, pressing the pause button and moving then the start button will tell the system that the same drain continues where you are. ‘**Stop**’ will stop the surveying of the area or the implementation of a design. Using the stop button in surveying tells the system that when you press start next it is a separate area. Using the same example as pausing, if surveying a drain pressing the stop button moving and then the start button will tell the system that this is a new separate drain. **Drain Surveying function**: The ‘**Start**’ ‘**Pause**’, and ‘**Stop**’ buttons will change function slightly when the software is set to survey drains. ‘**Start**’ will start the system surveying a drain. ‘**Stop**’ will end the current drain survey. Pressing ‘**Start**’ after this will start a new drain. Pausing collection is designed to allow for situations where the collecting vehicle cannot physically traverse a section of drain line. # Drain Surveying specific edit controls The following tools become available in the ‘**Collection**’ and ‘**Surfacing**’ stages if drain survey points exist. - Edit Drain - Merge Drains - Extend Drain - Split Drain ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/py2ykvydx0jhd62r9rmjwvpai4hd1cvfnowdw-png.png) ##### ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/1FAqvutwgg9e8y-sxwmfwl-mezc6sgzibmcrg-png.png)**Edit Drain** This button allows you to edit complete drain paths from the project. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/Bpjxfboctlzpfnn4yxyen4eo1hiefzo6o-eeg-png.png) After pressing the '**Edit** **drain**' button a window will appear with a list of available drain paths. Select a drain from the list, and press the corresponding button to either change the name of the drain or delete it. ##### **Merge drains** ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/eG35utr-9e5urxzmwq3a9tnevzggntatdtthg-png.png)This tool allows two drains to together at either end. When merging a copy of the original drains with the joining line will be made and you be given the option to delete the originals if you would like. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/ZHWiroepeqcfuv6ubatiimkrkejq8ujai-mmg-png.png) **Extend drain** ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/Jnfdoqvf6i-41q6hysk-c44jgt9xxjrclrz9w-png.png) This tool allows you to arbitrarily extend a drain from either end of the surveyed path. This can be useful if the drain needs to extend to a location that was not directly accessible by the surveying vehicle. Pressing the '**Extend Drain**' button will bring up the below screen. This screen allows you to extend the drain in whatever direction you wish. The red arrow shows the direction in which the drain will be extended, as well as which end of the drain will be extended. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/MiAizndjyjvnv2ynf2lvmvlnyyknuij3odl5a-png.png)Use the controls on the left hand side to select a drain. Then choose the length, elevation, and direction of the extension. ‘**Rel elevation**’ adds (or removes) the value entered into to the elevation of the existing drain end to calculate the elevation of the extended drain end. ‘**Abs elevation**’ Sets the extended drain end to the value entered. For example, to extend the drain 1ft below an ending elevation height of 100ft: Rel elevation value: -1ft Abs elevation value: 99ft Once you have finished making these adjustments press the 'Extend Drain' button. ##### ##### **Split drain** ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/HFZ3h2-4jbitbzuq4q-h9giu78siwlt2uymq-png.png)Split drain allows you to split a drain into two separate drains. First select which drain it is you wish to edit from the '**Which drain to split?**' drop down menu in the bottom center. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/TIiulertvwncrbppjkzhybzuvxziyvngrtj-q-png.png) Once a drain has been selected you can press anywhere along the drain profile. A blue arrow will appear to show where the split will occur. The arrow can also be moved using the left and right arrows found to the right of the ‘**Split at Distance**’ option. Create a Marker for referencing by choosing the Marker button. Name the new drain using the '**New drain name**' text box. Once you are happy with all of these settings press the '**Split Drain At Point**' button to apply the split. NOTE: The new drain name cannot be the same as an existing drain. The '**Split Drain At Point**' button will become disabled in this case. ### # 2D Current Position Tracking Options When surveying or implementing there are 4 options that control how vehicle location is tracked on the screen in 2D. The options for 2D tracking are ‘**Scroll**’, ‘**Center**’, ‘**Dir. up**’, and ‘Manual’. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/HI6efj9qqw3kaebxb2hge-lvf3mjtpk-soboa-png.png)**Scroll** This option will show the GPS position indicator moving freely on the screen and will move the screen as the indicator approaches the edge to ensure that the indicator is always present on the screen. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/0o6jaiwaajwbdjzfchbr0iy6nkmh-zwqnvm7g-png.png)**Dir. Up** When the ‘**Direction Up**’ option is active the map will rotate to make sure that the direction of travel is always to the top of the screen. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/yL7penidfqd57ojlwpes5d46uaet6t2ze8ang-png.png)**Center** The Center option has 2 parts, first it locks the indicator to the center of the screen so as it moves the map moves to make sure it stays in the center. The second part is that the map is locked to always have north at the top of the screen. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/bDXqeixmb2bpd4lgy72x9j26ikqxnhv3xxszw-png.png)**Manual** This option makes it so that the system does not lock the direction of the map or fixate on the location of the indicator so that even while surveying or implementing you can inspect other sections of the map. Caution: in this mode the vehicle icon can move off the edge of the map. # 3D Current Position Tracking Options When surveying or implementing in 3D there are 2 options available. The first option is ‘**Follow Tractor**’ and the second option is ‘**Stop Following**’. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/kJXshvhag5bafi7wddm1vm-dngmts91hd0tia-png.png)**Follow Tractor** This option keeps the tractor at the center of the screen at all times, the camera will be placed behind the tractor when pressed.. While in 3D viewing the camera can only be moved to view the tractor from various angles and will rotate with the tractor as the primary focus. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/JI6ybzrirmm4lohdap3c-jig8xk9r-75vgw2g-png.png)**Stop Following** This option stops the camera from following the tractor. While using this option the tractor is able to drive off the edge of the screen and the camera will not follow it, however whenever a change is made to the camera angle it will snap back to the tractor's current position and use the tractor as the focal point. # Screenshot ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/Koum-rh2t4imcmzilavtoawxv1vh7yst0mwta-png.png)In the top right of any mapping window is a small button with a camera. Pressing the camera button will take a screenshot of what is currently on the screen. After taking a screenshot a pop-up window will appear (shown below). Pressing ‘Yes’ will open the folder where the screenshot is saved. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/jMJpdd-dfrbbljbo67xfipphouu-1dkk1m79w-png.png) # Battery Level In the top right of the screen next to the screenshot button you will find the Battery level indicator. This indicator displays the tablet/computer's battery level and whether it is plugged into power or not. ![](https://docs.t3rra.com/uploads/images/gallery/2025-03/scaled-1680-/ZCQipt1irgundec75-myka-rsdthghbczhj5q-png.png)
