GIS Information
AGnVET Services offer the following services;
Accurate DGPS surveying and Mapping: Using the latest technology in GPS equipment, we produce accurate Farm Feature Maps and / or Green Hectare Maps. This provides the basis for all management records to be linked or be compatible with, digital data information such as GIS. Why pay more ? Having accurate maps can save you money with respect to licensing agreements, consulting services, spraying, sowing, windrowing and harvesting.
Pesticide Application Management Plans: As part of Best Management Practice guidelines, features such as neighbour notification zones and down-wind no-spray zones may be clearly marked on accurate maps, to contribute to the responsible use of pesticides.
Yield Map Overlays and Analysis: Using yield maps and other spatial data it is possible to create "multi - temporal yield analysis" (looking at the change in yield over time) and temporal stability (how stable each area is within the field). These can then be used to create field management zones for sampling or for further investigation.
GPS referenced soil / plant testing: GPS referenced test sites allow a continuum of information to be collected, to assess changes over time. This reduces spatial variability.
Variable Rate Technology: Variable rate technology uses specific paddock information to allow variable prescriptions of inputs such as lime & gypsum, to optimise resource management.
Multi-Spectral imaging and Remote Sensing Data analysis: Collecting spatially referenced information using different light bands allows variations across a paddock to be identified that often can't be seen by the naked eye. This information can be used to direct further analysis in the field to correct any imbalances before they impact greatly on productivity.
Electromagentic Surveys: EM surveys characterise soil differences below the soil surface by measuring electrical conductivity. Together with other historical information Zones or management units can be determined to aid in sampling strategies for GPS referenced testing.
