PORTOFOLIO KAMIOUR PORTFOLIO
Portofolio GIS & WebGIS: Studi Kasus GIS & WebGIS Portfolio: Case Studies
Berbagai sistem informasi geografis, geoportal, dan Digital Twin yang telah kami kembangkan untuk desa, instansi, dan perusahaan. Various geographic information systems, geoportals, and Digital Twins we have built for villages, agencies, and companies.
This page collects 13 GIS and WebGIS case studies built by PT Geo Anfa Spasial (GeoGap) — from lightweight interactive maps for village governments to OGC-standard geoportals and 3D Digital Twin City platforms. Each case study documents the context, the system we built, its key features, and its impact.
Our portfolio spans 2D WebGIS (Leaflet.js, PostGIS, Laravel), OGC geoportals (GeoServer with WMS, WFS, and WMTS), 3D WebGIS (CesiumJS, 3D Tiles, CityGML/CityJSON), and 3D Gaussian Splatting — a method we published in the GEOID journal (ITS). Sectors covered include village and sub-district government, land administration, plantations, road infrastructure, and heritage documentation.
