Change Detection (Lakes & Encroachments) system

Core Project Components

This project focused on developing a geospatial monitoring system to detect changes in lakes and surrounding land parcels over time. The objective was to enable early identification of encroachments, land-use changes, and environmental risks using time-series satellite data.

1. Baseline Mapping Layer – Water Body & Buffer Delineation

The system establishes an accurate baseline of lakes and their associated buffer zones.

Challenge:

Conventional monitoring methods lack temporal consistency and fail to capture gradual or unauthorized changes.

Approach:

Satellite imagery was used to delineate water spread areas, lake boundaries, and regulated buffer zones with spatial precision.

Outcome:

A reliable digital baseline for long-term environmental monitoring.

2. Change Detection Engine – Temporal Spatial Analysis

This layer identifies spatial changes by comparing imagery across multiple time periods.

Capability:

Automated detection of reductions in water spread, boundary intrusions, and land-use alterations around lakes.

Result:

Timely identification of encroachments and environmental degradation.

3. Decision Support Layer – Compliance & Planning Insights

The final layer translates detected changes into actionable insights.

Functionality:

Generates spatial indicators and reports to support regulatory review and planning interventions.

Impact:

Strengthens environmental compliance, supports sustainable urban planning, and enables data-driven governance.
