Support / The map & data / Reading your map
Your map is the proof of what the robot actually did, and where it struggled. Yardstick records every position the robot logs, then draws it as a coverage grid over a photo of your yard. The colors are the story. This page shows you how to read them.
The tiles across the top score the whole run in a glance, before you touch a single layer. They tell you how much of the yard got covered, how well the robot's GPS held up, and whether there is enough data to trust the picture.
Under the tiles is a row of layer buttons. Pick one and the coverage grid repaints to color every cell by that one measurement. There are three ways a layer can be colored, and knowing which one you are looking at is most of the skill.
A layer that has more or less of something. The good end recedes into the surface. Where color builds up is where to look.
A red palette that marks only where something happened. It is drawn only where it matters, so any red is worth a look.
A layer that just maps a fact, like slope or elevation. Color shows the shape of the thing, not a problem.
Each button below is one layer. The tag on each one tells you which direction is trouble: whether a high reading is the warning sign, a low reading is, or the layer just maps a fact with no good or bad end. Some layers are drawn only where the thing happened.
You do not need to read all eighteen. Most people start with two or three and only reach for the rest when something looks off.
Seeing a color you cannot explain? Open a support ticket and tell us which layer you had on and where the color showed up. Because Yardstick runs on your own machine, the full record is right there to look at.
