Most remote sensing based vegetation maps are plagued by issues with “noise” from soil colour 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 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.
Another helpful map that is automatically downloaded for your field is called the PurePixel Chlorophyll Index map. These maps separate chlorophyll information to help assess crop variability and maturity within a field or between fields. This information can be used to help evaluate mid and late season crop health to assist harvest related decisions.
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.
