{{#customtitle:Gathering Data on Field: GPS Module|Gathering Data on Field: GPS Module}} The GPS Module allows for data exchange between a GPS device and GeoAgro GIS. The data gathered with the GPS device can be downloaded to the computer and added to the GIS in new layers. Data can also be defined as GIS Points (Waypoints), Lines (Tracks) or Polylines (Routes) and transferred to the browser in order to be later used on field. To use the GPS module, activate the corresponding tab.

Note Note: This is one of the few exercises for which sample data is not provided, as you need a GPS device connected to the computer in order to work on the exercise. The same step-by-step method with sample data will be used to present the exercise, but in order to work on it you will need to connect your GPS and unload personal data that you have already gathered.

Exercises

Where to Do the Exercises


The first step to complete the exercises in this tutorial is to set up the computer you will be working on. You may either:

  • Work on your own computer: If you completed our Getting Started Course, your system and datasets are ready to go through this learning guide. You will be able to use our GeoAgro GIS trial version for 2 months. From now on, you are ready to begin with any learning guide you wish.
  • Work on a virtual computer provided by GeoAgro: This does not require any previous installation. See Prepare a GGS Tutorial on a virtual computer


The following instructions apply to either method, unless otherwise specified.

Exercise 1 – From GIS to GPS

To transfer the points to the GPS browser first you need to import the points to the GPS Module. Select the GPS tab and activate the Waypoints layer, as you are going to import points.

GPS Module

If you see points or polygons from previous exercises, press the “Delete all objects" tool. Delete objects

Select the “Import from GIS Module” tool in the Tool Bar located to the right.

GPS Module

A dialog box will open displaying a list of all the existing layers for the current project in the GIS Module. Select the “Sampling" layer and click 'Accept'.


Layer to export

Data

In the next box you will be able to make associations between the structure of the origin layer and the data that is stored in the device’s memory, in order to keep the names (numbers) assigned to the points.

Click on the “SamplingN” field in the Origin box (the right column) and then click on the "Identifier" field in the Destiny box to link both data charts. Then click “Accept”.

Field matching

On the GPS Module Map Window, you will see the points with their corresponding numbers.

Map window

Loading Data

To load the points to the GPS device you must plug the device to your computer and click on the Connection to the GPS device button Connect.

Once the GPS is connected, click on the “Send objects to GPS device" button Image:GIS_gps_Tool_02_01.jpg.

The georeferenced points will be stored in the GPS unit together with their corresponding identifying numbers.

Exercise 2 – From GPS to GIS

To do the practice, you must first take some GPS points. Next, these points will be downloaded in the GPS Module so that the gathered information can be then added to a GIS layer.

Connection

Click on this icon to automatically set the communication between the GPS Module and the portable GPS navigation device that is plugged to the computer (no previous configuration required). If connection fails, a box will appear indicating the possible causes. Conflicts generated by the adapter cable that connects the portable GPS to the laptop's USB port are very common. See Connecting the GPS to the PC.

Import

Activate the Waypoints layer. By doing so, you will indicate to the system that you want to download only the points stored in the browser (not the tracks or the routes).


Click on the Download objects from the GPS device tool GeoAgro GIS will search all the Waypoints (points) stored in the GPS device.

  • A dialog box will pop up displaying the progress for the operation.


When this is finished, the objects will have been downloaded and will be displayed in the work window of the GPS Module.
