VIII. FIELD PROCEDURES

A. Locating Sampling Points1. The coordinates of the predetermined sampling points (shown in Table 1) must be uploaded to the hand-held GPS that will be used in the field.2. These coordinates shall then be navigated using the navigation tool of the hand-held GPS.3. Near the navigated point, the final location of sampling points shall be decided in the actual ground wherever is the most convenient place to conduct spectral measurement.4. These final sampling points shall then read of its location using the hand-held GPS.

B. Setting Up the Instrument and Software 1. Connect the reflection probe to the spectrometer as well as the laptop computer with the use of appropriate connectors.

Figure 1. Typical reflection setup(Note: It is recommended to conduct reflection measurement between 9:00 AM to 2:00 PM considering good weather conditions (sunny, cloudy, variable) in which there is a valuable source of light from the sun.)

2. When everything is set-upped, launch SpectraSuite in your laptop computer. Choose File > Save > Save Spectrum. The Save Spectrum dialog box will appear.

Figure 2. Save spectrum menu in the SpectraSuite interface

3. In the Save Spectrum dialog box under the Save Options, choose Save every scans and below check Stop after this many scans: and put 30. Under File Options, choose the File type as Tab Delimited; in the Save to Directory, click and navigate to your working directory for the particular spectrum (reference, dark or sample/target) to be measured. Put your desired Base Filename and set the Padding Digits as 5. Then, click Accept. This setting will automatically save your data to your directory for a particular spectrum when you press Ctrl + S or click with thirty (30) records to be averaged.

C. Taking Measurements1. To ensure the relevance among all measurements for every sample, taking spectral measurement shall be done twice for the reference spectrum (before and after), trice for the sample (at different points within its canopy) and none for the dark spectrum (dark spectrum is constant).2. First, spectral measure shall be done for the reference spectrum.3. Place the reflection probe at a desired distance from the white standard (1.5cm-15cm) with an angle of incidence (AOI) of 45 with respect to the surface of the standard. White standard is an ideal reference because its nearly 100% reflected. AOI of 45 can have your reflection to transmission ratio be equal. Hence, the larger the AOI, the higher the R/T ratio.

Figure 4. Figure showing the desired setup when measuring the reflectance

(Note: You can attach a stick with a length equal to your desired probe-to-target distance adjoining the probe to ensure consistency of this distance.)

4. In SpectraSuite software, with the set-up as stated in B-3, press Ctrl + S or click at the spectrum toolbar. You can navigate to your directory and check if the needed data are already saved.5. Next to measure is the desired target, the sample, in which three (3) points on the sample which are more likely apart from each other must be selected.6. Procedures C-3 and C-4 are just repeated but this time, instead of the white standard, the top of the sample which is exposed to sunlight is the target of the probe. 7. Same process (C-6) is done for the other two (2) points of the sample.8. After taking the three measurements for the sample, another measurement for the reference spectrum shall be conducted. Procedures C-3 and C-4 are repeated.
