Each layer has a limit of detail, and knowing this changes how it should be read. It is expressed in two ways depending on the type of data: as a scale in the soil survey map —1:50.000, 1:500.000— and as a pixel size in the raster layers —30 m, 1 km—.
| Resolution | What distinguishes | Example |
|---|---|---|
| 30m | Differences within a paddock | National Crop Map |
| 1km | Differences between areas, not between properties neighbors | Climate, texture, organic carbon |
| 1:50.000 | Differences within a property | Soil survey maps provincials of soil |
| 1:500.000 | Regional differences | Soil survey map national of soil |
The practical consequence: with a 1 km layer, two properties boundaries will show the same rain and texture value, because they fall on the same pixel. That is not a data error, it is its resolution.
A small property may not contain the center of any pixel in a 1 km layer. In that case the section does not appear directly, instead showing a value taken from a neighboring pixel.
