Can I draw my farm's plots on a map and calculate their area?

Yes. In Owari Agro, under Plots > Geolocate, you draw each plot's outline on a satellite map, save it and download it as GeoJSON or KML. The area in hectares doesn't come from the drawing: the system calculates it from the plot's number of trees and planting spacing.

How to draw a plot

1. Go to Plots and open the Geolocatetab. Each plot has a «Geolocate» action, or «Edit geometry» if it's already drawn.
2. Find the land: type in «Search address or place…» or use the location button, which centers the map on where you are.
3. With the polygon tool, at the top left of the map, mark the outline's corners one by one. You can adjust them later.
4. Tap Save geometry. If you need to delete it, use Delete geometry.

Each plot has a single polygon: if you draw another one, it replaces the previous one. Corners are marked by hand on the satellite image; the system doesn't trace the plot by walking it with GPS.

Download the farm map

• By plot: the «GeoJSON» and «KML» buttons, in the editor or on the plot's row, without opening the map.
• Whole farm: Farm GeoJSON and also Farm KML, with all the drawn plots.

They are standard map formats, handy for sharing the farm with an agronomist or opening it in mapping software.

And the plot's area

The area Owari Agro uses on the Home screen («Area (ha)» and kilos per hectare) is calculated from two plot details: the number of trees and the planting spacing in meters. For example, 5000 trees at 2 x 1 meters make 1 hectare. The polygon is there to locate the plot and share its shape, but it doesn't measure the surface or change that calculation. Units are fixed: meters and hectares.

If you want the area to be right, check that every plot has the correct number of trees and planting spacing. How it's then used for yield is explained in yield per tree and per area.

Available on every plan

Plot geolocation has no plan limit: it's included in Seed too. In the Geolocate list each plot shows its variety and crop type, so on a farm with several crops you know which one you're drawing; see how to organize coffee, plantain and other crops.
