GeoJSON and GeoTIFF in a farm-mapping workflow
Choose a format according to whether the information represents features, attributes, or continuous image pixels. Preserve identifiers, coordinate metadata, dates, units, and nodata definitions across exports.

Agricultural GIS layers: a practical information model
Separate field boundaries, infrastructure, crop observations, imagery, and analysis results into layers with explicit relationships. Define which fields are mandatory and who maintains each layer.

Sampling agricultural imagery with zonal statistics
Define the polygon, pixel inclusion rule, nodata handling, and summary statistics before comparing fields. Inspect distributions and valid coverage rather than relying on a mean alone.

Geotagged agricultural photographs that remain useful
Capture enough context to interpret the photograph later: field code, direction, subject, date, and the condition being documented. Keep the original file and connect it to the observation record.

Surveying agricultural water and irrigation assets
Map outlets, pumps, gates, reservoirs, pipes, and canals according to the operational system. Record asset condition and the dates on which flow or performance observations were taken.

Agricultural map sharing and responsible access settings
Decide what a viewer needs to see and which data should remain restricted. Review farmer identities, precise locations, photographs, and commercial information before publishing a shared map.

Building a repeatable agricultural GIS monthly report
Fix the reporting period, geometry version, quality rules, and field register used for each issue. Keep a record of revised source data so that readers understand changes between editions.

Rice crop calendars from field records and satellite imagery
Record nursery, transplanting or direct-seeding dates, water-management events, and harvest observations. Compare fields according to their actual cycle rather than one assumed regional planting date.

Rice irrigation monitoring: observations before prescriptions
Connect field water-level observations, irrigation delivery, rainfall, and crop stage. Distinguish standing water, saturated soil, and canopy condition in both the survey and the map.

Wheat growth-stage monitoring through a complete season
Link sowing dates, variety, management, and field observations to the image series. Compare establishment, canopy development, heading, and senescence within relevant seasonal groups.
Read article ↗
Wheat drought and heat-stress assessment with spatial evidence
Review crop stage, rainfall, temperature observations, soil conditions, and canopy changes together. Inspect contrasting parts of fields and use local agronomic guidance for the timing of ground checks.

Agricultural water productivity: reading remote-sensing estimates
State the definition and units of water productivity and identify whether the water measure represents evapotranspiration, irrigation delivery, or another quantity. Keep the crop-output reference consistent.
