WebGIS, Geoportal & Digital Twin Services
PT Geo Anfa Spasial (GeoGap) is a legally incorporated geospatial technology company based in Sleman, Special Region of Yogyakarta. We build web-based spatial information systems — from lightweight interactive maps to OGC-standard geoportals and 3D Digital Twin City platforms.
We do not resell templates. Every system is designed around your actual data, workflow, and hosting constraints. Choose a Non-GeoServer architecture when you need something fast and inexpensive to run, or a GeoServer stack when interoperability and OGC standards (WMS, WFS, WMTS) matter. All source code and data stay under your control.
Below are our four core services. Each page explains the scope, the technology, the deliverables, and links to the case studies where we applied it.
Custom 2D & 3D WebGIS Development
We build custom, standalone, and responsive web mapping platforms (WebGIS) focused on real functionality without overloading your server architecture.
