Secure Geoportal for Automated Survey Quality Assurance and Data Management

Geoportal Web Interface – Nyeri Municipality

The Secure Geoportal for Automated Survey Quality Assurance and Data Management is a GIS based web platform designed to modernize survey workflows and enhance data accessibility within Nyeri Municipality. Developed using ArcGIS, GeoServer, PostgreSQL/PostGIS, and web technologies (HTML, CSS, and JavaScript), the system automates survey quality assurance processes and provides a secure, centralized environment for spatial data management.

Geoportal features an intuitive interactive web interface that allows surveyors to visualize spatial datasets, retrieve historical survey records, and monitor survey quality in real time. Users can easily navigate through map layers and access spatial information relevant to land management and survey operations.

Identifier Tool

The Identifier Tool enables users to select specific parcels or features on the map and instantly view detailed attribute information. This function supports quick inspection of survey data and verification of land parcel details.

Measurement Tool

The Measurement Tool provides precise functionality for measuring distances and areas directly within the map interface. It enhances accuracy assessments, field validation, and general spatial analysis during survey workflows.

Spatial Query Tool

The Spatial Query Tool empowers users to perform advanced searches and filtering based on spatial relationships or attribute criteria. This feature allows efficient extraction of specific datasets and facilitates focused spatial analysis.

Computational Checks

The Computational Checks component performs automated data validation to identify inconsistencies or errors within survey datasets. This ensures data integrity, reliability, and conformity to set standards before approval or publication.

Conclusion

These integrated tools make Geoportal a comprehensive digital environment for survey quality assurance and spatial data management. The system enhances accuracy, transparency, and operational efficiency, supporting sustainable land administration and informed decision-making across Nyeri Municipality.
