SATELLITE MONITORING + CITIZEN SCIENCE

Turning environmental data into student-led action.

GreenScope is a school-centered community WebGIS that translates Sentinel-2 vegetation-change indicators into field-verification missions for students and nearby residents around SMP Islam Al-Azhar 19 Cibubur.

How it works

Satellite Data Status Loading analysis… Sentinel-2 Surface Reflectance data processed in Google Earth Engine. Satellite indicators are screening evidence, not automatic proof of tree loss or a planting recommendation.

2026 Mean NDVI—June 1–August 23 median composite

NDVI ≥ 0.35—Working vegetation indicator

Field Observations0Anonymous citizen-science records

Sites for Review0Hardscape or exposed-area observations

Mean NDVI — 2022—Historical baseline

Mean NDVI — 2026—Current comparison period

Relative Mean NDVI Change—2026 relative to 2022 baseline

Community Study Radius250 mSchool-centered pilot area

Decreased Signal—ΔNDVI below −0.05

Relatively Stable—ΔNDVI −0.05 to +0.05

Increased Signal—ΔNDVI above +0.05

Study Area19.40 ha250 m school-centered community AOI

COMMUNITY MOVEMENT

One shared mission: verify what the satellite cannot explain.

GreenScope turns environmental monitoring into participation. Every anonymous field observation adds ground context to the satellite signal and helps the community distinguish existing vegetation, low vegetation, hard surfaces, and exposed areas.

Field workflow: Pilot Area → Survey Mode → click a real location → observe the ground condition → select a category → add a short environmental note → save. Do not submit names, phone numbers, home addresses, or other personal information.

GREEN ACTION LOOP

Observe → Verify → Act → Monitor

Mission 01 Verify vegetation-change areas identified by satellite analysis.

The 2022–2026 comparison screens where vegetation signals decreased, stayed relatively stable, or increased. Ground observations are used before any local cause or intervention is claimed.

HOW GREENSCOPE CREATES SOCIAL + ENVIRONMENTAL VALUE

From remote sensing to a repeatable community action cycle.

1DetectSentinel-2 identifies vegetation-signal change across the pilot area.

2UnderstandThe WebGIS makes the evidence understandable without GIS software.

3VerifyStudents and residents record anonymous ground observations.

4DiscussThe school community reviews observations before proposing action.

5MonitorThe same area can be checked again after protection or greening activities.

ENVIRONMENTAL OUTCOME

What GreenScope measures

GreenScope monitors changes in vegetation spectral response and provides a structured way to verify local land conditions. It does not assume that every decrease is caused by tree removal. Field evidence is part of the method.

SOCIAL MOVEMENT OUTCOME

What participation changes

The school becomes a community environmental anchor: students move from passive awareness to collecting evidence, discussing local conditions, and monitoring whether community actions correspond to measurable environmental change.
