Siting using the Vernier LabQuest, GPS sensor, and Light (or wind) Meter & Downloading Data for Use in ArcMap You will now have the opportunity to obtain simultaneous light intensity and location data using the Vernier Labquest. You will then export the data via LoggerPro software from Vernier into a usable format for ArcGIS. Obtaining data 1. Grab your Vernier LabQuest, GPS sensor, and light or wind sensor 2. Set the light sensor to the largest range, 0-150,000 lux, for being outside 3. Plug-in the two sensors to the LabQuest and head outside. The GPS sensor plugs into the USB port at the top of the device. 4. Once outside, wait for the GPS to acquire a signal. This will be evident when the latitude and longitude change from 0.00000. 5. Touch the “mode” box on the right side and change the selction from “time based” to “selected events”. A name is not required. 6. On the top of the screen, tap the x-y column data to enter the table screen. The graphing screen is not helpful with this type of measurement. 7. Get into the desired position and hit the play button This lesson was created for NYSERDA School Power…Naturally by the Institute for the Application of Geospatial Technologies (IAGT) under the Applying Geospatial Technologies for Expansion of School Power Naturally Program, Grant # 10981 8. Info will now be stored in the table. 9. Move to your next location and hit “keep” 10. Repeat for as many steps as needed/desired. 11. Click the stop button to end data collection Downloading data 12. Begin by making sure the data collection has stopped. 13. Open up LoggerPro on the computer. It is listed under Program Files Æ “Vernier Software”. 14. Unplug the two sensors, then use the USB wire to connect the LabQuest to the USB port of the computer. 15. LoggerPro should recognize the LabQuest and ask you if you want to retrieve the remote data. Click “yes”. It is fine to load it into the same window, so click “OK” to import the data into the current session. 16. You now have a table of x-y data based on latitude, longitude, and light intensity. Altitude is there as well, but not useful for this lab. Exporting Data to ArcMap Note: To export the data for use in ArcGIS or other GIS software, you have a few options. You can export as a text file (.txt), a .csv file, or GIS format. It is also possible to export directly to Google Maps and see your latitude/longitude data on a GoogleMap, but it will not show other data. 17. Make sure you have exported the data from your Vernier unit to a .txt or .csv file and that you have exported to a location you will access in future steps. Write down the path to your file below. Saved location: _____________________________________________ Note: You can export from Vernier as a GIS Shapefile. If you do this step, you will only need to Add Data. You will not need to go through the Add XY coordinate steps. However, you will need to define the projection for the file.

View your .txt document in Notepad. Double check to make sure you have all the important information and do any cleanup that may be necessary. 19. Open the ESF Vernier.mxd ArcMap document. Mapping Your Locations 20. Connect to the folder of your saved location above by using the “connect to folder button”. This will give you access to the location and all the data that you have in there. 21. Add your lastname.txt to your map document by clicking the "Add Data" button either on the menu bar or from File > Add Data. This lesson was created for NYSERDA School Power…Naturally by the Institute for the Application of Geospatial Technologies (IAGT) under the Applying Geospatial Technologies for Expansion of School Power Naturally Program, Grant # 10981 22. From your menu bar, select "Tools" and "Add XY Data." 23. Use the drop down arrow to select your lastname.txt file. Specify the X and Y coordinates based on the column names for latitude and longitude used in your text document. Do NOT hit OK yet. Select the "Edit" button to assign a coordinate system. 24. After hitting "Edit", hit "Select" a predefined coordinate system and navigate to the WGS 1984.prj file: Geographic Coordinate Systems > World > WGS 1984.prj This lesson was created for NYSERDA School Power…Naturally by the Institute for the Application of Geospatial Technologies (IAGT) under the Applying Geospatial Technologies for Expansion of School Power Naturally Program, Grant # 10981 When your screen looks like this, hit OK. 25. Select "OK" to a message that looks like: **You have now added the points that you collected in the field to your map. Now it’s time to look at the additional data that you collected at each point.** Symbolizing Your Data 26. On the left side of your screen, highlight the layer you just created from the XY points. Right click the layer and select "Properties".

Select the "Symbology" tab. Select "Quantities" on the left side and fill in the "Value" box with the field name that contains the information collected from the Vernier Sensor (i.e. Illuminati). Hit "OK." Congratulations! You have now created a map using Vernier Units with GPS sensors.
