Yield Data Import

Import harvest yield data into GeoPard for cleaning, calibration, analytics, and zoning.

To upload as-applied data files choose the Import Data menu and the Upload Files item. Then select Yield Data.

Keep in mind that there are some restrictions:

• Only WGS84 (EPSG:4326) shape files are supported with points or polygons-based data.

• The attributes must be a Numeric type (Integer or Real, not String).

• 100MB is the maximum file size.

• Try to eliminate the usage of special symbols like %+@ in the attribute titles.

• The maximum amount of attributes is 20.

• Each archive is treated as a single dataset (*.shp and *.dbf files are mandatory).

Upload Yield Data as Shapefile

1. You can either drag and drop single or multiple Yield Datasets to the panel or click the Browse button and select a dataset from your computer.

2. Click the Upload button. Then GeoPard will verify that the file meets the requirements and save the data.

Wait for the confirmation dialog to see that the dataset was uploaded successfully:

The Yield Dataset will be available in the tree in the Yield Data section for further interactions including ZonesMaps creation.

Yield — Metadata & Units Reference

Each shapefile archive can optionally include a <filename>-Metadata.json file. The DataAttributes array tells GeoPard how to label and unit-convert each column. Unit strings use compound notation: t1ha-1 = t·ha⁻¹, km1hr-1 = km·h⁻¹.

Unit Strings Reference

Relevant unit strings for field operations

Unit string	Meaning	Used for
t1ha-1	metric tonne per hectare	Dry mass yield, lime rate
[m3]1ha-1	cubic metre per hectare	Volumetric yield (combine)
l1ha-1	litre per hectare	Liquid fertilizer / chemical applied rate
kg1ha-1	kilogram per hectare	Dry/granular fertilizer rate
ha-1	per hectare	Seeding rate (seeds/ha)
prcnt	percent (%)	Moisture, dry matter, humidity
km1hr-1	kilometre per hour	Vehicle speed, wind speed
m	metre	Swath width, distance, elevation
cm	centimetre	Planting depth
in	inch	Planting depth (US imperial)
l	litre	Fuel consumed
C	degrees Celsius	Air temp, soil temp
arcdeg	degrees of arc	Machine heading / bearing
bu	bushels	US yield volume
bu1ac-1	bushels per acre (non-standard)	US yield rate — prefer t1ha-1

Compound unit notation rules

Multiplication is written with 1 between tokens: km1hr-1 = km × hr⁻¹

Division uses negative exponent suffix -1: t1ha-1 = t × ha⁻¹ = t/ha

Cubic metres use brackets: [m3]1ha-1 = m³/haSimple per-unit (no numerator): ha-1 = per hectare
