At FarmTRX we want users to be able to get empowering insight from their yield data off any combine, whether they’re looking for fine detail coming through in precision maps or just for monitoring live readings in the cab.  In the FarmTRX Web App farmers can choose from 9 different outputs to visualize their yield and moisture data – from raw unfiltered points taken directly from the yield monitor to automatically corrected precision maps.

When FarmTRX yield and moisture data syncs to the cloud, it is automatically processed into a variety of yield and moisture maps. Automated precision mapping is part of the FarmTRX Premium Web Service, which all customers have access to for one year after purchase. More info on FarmTRX Premium here!

Users can choose from the following 9 map views to see their yield data:

1) Boundary

The Boundary marks the extent of your field. All recorded yield and moisture data from FarmTRX lands within a field boundary upon yield data sync, therefore boundaries need to be created in your Web App account to see yield maps. Boundaries are drawn or imported by the farmer and can be customized at any time. If factors like surface water or tree clearing impact the area harvested one year, farmers can change their field boundary to reflect it accordingly. Have a test plot in your field? You can draw smaller sub-field boundaries within a larger one to get separate precision maps for both.

2) Raw Yield Points

The Raw Yield Points display shows every point the yield monitor collected while combining, with a new point created every two seconds. Different point colours represent different harvesters with a FarmTRX Yield Monitor. In this view, the raw yield points have yet to be corrected so users can still see any potential miscalibrations, incorrect crop inputs, headland turns, transits to unload or partial rows.

3) Raw Yield Map

The Raw Yield Map is the interpolation of your raw, unfiltered yield data values. Any miscalibration or incorrect values input before harvesting will still be visible in this view. Areas where false yields were recorded, such as when the combine slowed  significantly, picked up a swathed “clump” or turned will be visible in this map. 

Fortunately, with FarmTRX users can edit their field settings after data sync. If an incorrect crop type or header was selected, or the user did not connect to the yield monitor before harvesting, they can still get accurate precision maps for the field by adding the total yield after the fact using an elevator ticket.

4) Corrected Yield Points

Like the Raw Yield Points, in the Corrected Yield Points map users will find the data points generated by the FarmTRX Yield Monitor during harvest, with one big difference. Here, all visible data points have gone through FarmTRX’s data analysis process to be cleaned and corrected. The Web App automatically detects and adjusts misleading yield points, performs multi-combine normalization, removes headland turns, modifies partial rows, identifies changes in calibration from day to day and makes several other checks and corrections to produce a final, accurate collection of yield points.

5) Corrected Yield Map

The Corrected Yield Map is an interpolated map based off the corrected yield points. The map is a continuous grid surface, colour shaded to indicate relative high and low yield areas. The color shading and corresponding legend allow growers to easily see the range of yield variation in their field with high-resolution definition and clarity. This map display is best used in a close review or when scouting.

6) Classified (Zoned) Yield

Instead of a smooth change in colour themes indicating variations in yield, the Classified (Zoned) Yield map distinctly separates yield performance into 5 classes or “performance zones”. Each of the 5 yield classes make up a twentieth percentile of the total harvest field area, ranging from lowest to highest. Variation between the classes is crisp and clear, making it easy to see and quantify areas that could benefit from remedial treatment.

7) Trend of Yield

The Trend of Yield Map is another variation of the interpolated Corrected Yield Map. Here, the general yield trends have been smoothed to take out smaller, local variations which can be irrelevant to a large-scale treatment plan. The Trend Map offers growers a “big picture” perspective on their yield tendencies. This is especially powerful when viewing across multiple fields, as the effects of larger drainage patterns, soil zones or power zones come into focus.

8) Raw Moisture Map

The Raw Moisture Map is computed using the grain moisture values generated by the FarmTRX Moisture Sensor. The moisture sensor takes multiple readings per second and averages a moisture reading that is sent to the FarmTRX Yield Monitor every 10 seconds. The Raw Moisture Map is created from this data.

9) Swath Map

The swath map is created from corrected yield points collected across a header width. Unlike the Trend and Corrected Yield maps the Swath Map shows the movement and direction of the harvester without smoothing across a continuous surface. The Swath Map is helpful in picking out pass-to-pass differences, particularly for evaluating in-field trials.
