## Tutorial: Spatial Analysis of Accessibility of Wells using Map Algebra

### 3. Condition 1: Wells within 150 Meters of Houses or Roads

#### 3.4. Create Zones of 150 Meters Around the Roads

In a similar way we can now calculate the 150 m buffer around the roads.

1. Style the roads layer. Use these classes:

2. Repeat the steps used to calculate the zones of 150 m around the houses, but use the roads layer as the Input layer and name the output roads150m.tif.
