Become a Map Labeler (Data Annotator)
You'll annotate satellite imagery by drawing and correcting map features (buildings, roads, and landcover). Your work helps create accurate digital maps used for navigation, planning, and location services.
What you'll work on
- Building creation: draw building footprints on blank maps.
- Building repair: fix pre-labeled building shapes.
- Road centreline: draw road center lines + measure width.
- Landcover: label land areas by classification.
✨ Quick overview
🧠 What makes a strong labeler?
Consistency
Follow the same rules every time: geometry, tags, and boundary alignment.
Attention to detail
Clean corners, avoid overlaps/gaps (unless instructed), and ensure correct classifications.
Coachability
Use pushback feedback as free training. (It's annoying… and very useful.)
Speed + quality balance
Benchmark targets matter, but poor quality can reduce earnings due to rework.
📘 What the job entails
As a Map Labeler, you'll interpret satellite imagery and convert it into structured map data. You'll draw shapes (polygons/lines) and apply correct classifications so the map matches reality.
🧩 Mapping services (projects)
🏢 Building creation
Label buildings and draw their shapes on blank maps.
- Trace roof footprints accurately
- Follow corners/curves cleanly
- Separate adjacent structures correctly
🛠️ Building repair
Correct inaccuracies in pre-labeled building shapes.
- Fix shifted/warped polygons
- Split/merge shapes when needed
- Remove false positives
🛣️ Road centreline
Draw lines in the middle of roads and measure their width.
- Follow road curvature
- Keep centerline centered
- Set width per instructions
🌿 Landcover project
Label areas of land based on their classification.
- Forest, water, urban, agriculture, etc.
- Use consistent boundaries
- Resolve ambiguous imagery carefully
🔎 Workflow (quality control)
Your work goes through a quality control process before it's approved and paid.
Labeling
You download a task and complete the annotations.
Checking
A checker reviews quality. Substandard work is "pushed back" to you for corrections.
Judging
The work is sent to a higher-level judger for deeper review and consistency.
Reviewing
Finally, a reviewer approves the task and payment is processed.
🏅 Promotion
📈 How promotions work
High-performing labelers can be promoted to higher-paying roles such as Checker and Judger.
- Consistent accuracy
- Low pushback rate
- Good communication & accountability
💼 Role expectations
As you move up, the focus shifts from "doing tasks" to "protecting quality across many tasks."
- Checker: review others' work + send actionable feedback
- Judger: resolve edge cases + enforce standards

💸 Payment Sample
Standard rate: 75 pesos/hour
The standard rate is 75 pesos per hour but it can change depending on your speed and quality. It varies on how fast or slow you finish tasks. It can increase if you finish faster than the average speed needed per hour, and decrease if not.
🏗️ Sample benchmark table (projects)
Reference: building repair and related tasks.
| Project | Task | Features/layers | Standard Rate |
|---|---|---|---|
| Building Repair (BR) | 800 | 75 pesos/hour | |
| Filter | 240 | 75 pesos/hour | |
| 3D Matching (3DM) | 60 | 75 pesos/hour |
🌿 Landcover (LC) Project
Benchmarks can vary by density level. The table below shows sample expectations (speed per task → tasks per hour).
| Density level (Features/buildings) | Average speed per task | Task per hour | Standard Rate |
|---|---|---|---|
| 1-5 | 60 seconds / 1 minute | 160 bldgs/hr | 75 pesos/hour |
| 6-10 | 90 seconds / 1.5 minutes | 290 bldgs/hr | 75 pesos/hour |
| 11-50 | 180 seconds / 3 minutes | 300 bldgs/hr | 75 pesos/hour |
| 51-100 | 600 seconds / 10 minutes | 400 bldgs/hr | 75 pesos/hour |

How to use this table
- Use it as a target pace, not a stress test.
- Faster is good only if your quality remains high.
- Repeated pushbacks can reduce effective earnings due to rework time.
