Standard Terms of Engagement & Spatial Services Agreement

1. Engagement Framework

These Terms of Engagement govern all technical proposals, Statements of Work (SOW), and service deliverables commissioned from gsVista. Each engagement is formally initiated upon mutually agreed Terms of Reference (TOR) or an executed proposal document detailing the Area of Interest (AOI), analytical parameters, sensor types, and deliverable schedule.

2. Coordinate Datums & Spatial Projection Standards

Unless explicitly specified otherwise in writing, all spatial deliverables prepared by gsVista are referenced to the World Geodetic System 1984 (WGS84 / EPSG:4326) or the appropriate Universal Transverse Mercator (UTM) projection (e.g., UTM Zone 31N / 32N for Nigerian territorial boundaries). Clients must verify target datum compatibility with their internal CAD or GIS systems prior to project sign-off.

3. Sensor Resolution & Technical Disclaimers

gsVista utilizes state-of-the-art satellite radar (SAR) and optical sensors. Clients acknowledge that satellite-derived observations:

• Depend on orbital revisit intervals, optical cloud cover conditions, and atmospheric transmission windows.
• Hydrodynamic flood models, vegetation indices (NDVI/EVI), and land cover classifications represent remote sensing estimations based on calibrated mathematical models and digital terrain datums.
• Satellite assessments are designed to complement, not completely replace, statutory geotechnical ground borings, intrusive foundation soil tests, or legal boundary land registry surveys.

4. Deliverables & Intellectual Property Rights

Upon receipt of full payment under the agreed project milestone schedule:

• The Client receives full, non-exclusive rights to use, modify, and integrate final deliverable products (including Shapefiles, GeoPackages, GeoTIFFs, and Cartographic PDF Reports) for their internal business operations and tender submissions.
• gsVista retains ownership of its proprietary processing algorithms, custom scripts, internal models, and training libraries developed during execution.

5. Invoicing & Payment Terms

Targeted feasibility assessments typically operate on a milestone schedule (e.g., 50% mobilization advance upon contract execution and 50% upon delivery of final spatial data layers). Recurring satellite telemetry retainers are billed on monthly or quarterly cycles in advance.

6. Governing Law & Jurisdiction

These terms are governed by and construed in accordance with the laws of Lagos State and the Federal Republic of Nigeria. Any disputes arising in connection with an engagement shall be submitted to mediation prior to formal arbitration in Lagos.
