PurePixel

Benefits
  • Saves time by targeting specific locations for crop scouting versus scouting the entire field
  • Reduces economic losses by providing an early warning system for crop health
  • Improves management decisions by comparing PurePixel maps to other field operations maps such as as-applied fertilizer, as-applied seed, and yield maps
  • Identify differences in crop health and maturity even when crop health is generally strong

The PurePixel™ solution, part of Trimble's Connected Farm™, provides farmers and their trusted advisors with a high precision source of vegetation health information to drive improved crop analysis. Most remote sensing based vegetation maps are plagued by issues with "noise" from soil color and moisture variability. Furthermore, these maps generally use non-calibrated information that limit the user’s ability to compare crop health from one period to the next. The PurePixel solution not only removes the noise that undermines the accuracy of most vegetation maps, but also uses a precise calibration that allows for more meaningful analysis of the vegetation map information. Overall, the PurePixel solution provides high quality vegetation health information to improve farm and field management.

 

Types of PurePixel Maps

There are two types of PurePixel Vegetation Index (PPVI) maps. The first type uses a Natural distribution which displays crop health on an absolute scale to show the true state of vegetation health. The second type uses a Clustered distribution to display crop health with percentile buckets that accentuate the crop health variability. Between these two maps users can compare multiple images of the same area over time to detect changes in crop health and variability, no matter how large or small the differences.

Compatible Data Export

PurePixel maps are compatible with other third party software solutions, including Farm Works Software®. Click the Download button to export PurePixel Vegetation Index and PurePixel Chlorophyll Index data using a standard shapefile (*.shp) format. This allows flexibility outside of Connected Farm if a different system is needed for management zone creation or variable rate calculations.
