The objective of this sub-section is to give an overview of equipment that is used for measuring some of the variables mentioned under the various farm level survey categories. Focus will be on instruments used within STARS. A brief explanation of the mode of operation of each instrument will be given (with relevant references to manuals) and obtainable data formats will be elaborated. The following categories of equipment are discussed:
- Locational equipment: e.g. handheld/kinematic GPS for measuring field boundaries, area and ground control points
- Equipment for monitoring crop growth: e.g., AccuPAR, measuring rod/tape and SPAD
- Equipment for measuring other biophysical factors: e.g., automatic weather stations, manual rain gauges and soil moisture devices.
