How do I map data collected on a LabQuest or LabQuest 2?

The following steps describe how to collect data including latitude and longitude on a LabQuest or LabQuest 2, and display it on a map.

1. Set up the GPS receiver.
• (LabQuest 2 users) Enable the built-in GPS by choosing Sensor Setup… from the Sensors menu of LabQuest app. Check the GPS box and tap OK.
• (Original LabQuest users) Connect a Vernier GPS Sensor, order code vgps, $64 to the USB port of the original LabQuest.

2. Once the GPS has acquired enough satellites, latitude and longitude values will be displayed. Note: The first time GPS is enabled, it may take several minutes to determine its location. To minimize this time, orient the LabQuest screen upward, toward an unobstructed view of the sky, and do not move until latitude and longitude values are displayed. Subsequent connections will take less time. Altitude, speed, and direction over ground will also be collected once data collection has begun. These data will be available in the data table.

3. Confirm the data-collection mode is appropriate. If the GPS is the only sensor being used, the default data-collection mode will be Time Based. If it is being used with another sensor, the default data-collection mode is Selected Events. You may also consider using Data Matrix mode.

4. Collect data.

5. Save your data by selecting Save… from the File menu.

6. Connect LabQuest to your computer and launch Logger Pro.

7. If your data was still being displayed on LabQuest, Logger Pro may detect it and prompt you to import. If not, go to the LabQuest Browser under the File menu, and choose Open. Select the desired file from the list and open it.

8. Two mapping options are available by choosing Export from the File menu of Logger Pro:
• GIS Format: Choosing this option saves the data as a tab delimited text file specially tailored for GIS software such as ESRI’s ArcGIS family. The file can then be imported into the GIS application as a table of x,y data.
• Google™ Maps: If connected to the internet, choosing this option displays your data on a Google Map. A dialog box allows you to make choices such as whether you prefer to map discrete points or a connecting line. When ready, click OK and Google Maps will launch in your browser displaying your data.

9. If you wish to add an image of the map to your Logger Pro file, capture it using a screen capture utility and save as a jpg. In Logger Pro, choose Picture from the Insert menu, and select your image.
