GIS engineering & spatial analysis
Need a location question answered with data?
Location intelligence
Site suitability, catchments and competitor analysis for new branches.
Thematic & environmental mapping
Land cover change, vulnerability and erosion mapping from open and satellite data.
WebGIS & spatial data
Web maps, geocoding and clean datasets your team can open and use.

Deliverables in IOGP SSDM
The Seabed Survey Data Model is IOGP's GIS data model for delivering seabed survey results. It replaces loose CAD files with structured features that load into the client's GIS.
I process survey data and package it to SSDM: features, attributes and metadata, checked against the project specification.
Processed survey data
- Bathymetry
- SSS & MAG contacts
- Pipeline events
- DWG charts
Structure and check
- Schema mapping
- Attributes & domains
- CRS
- Metadata
SSDM delivery
- Geodatabase
- QC log
- Matches the charts
Selected projects
Client data is confidential. Samples are sanitised or shown with client permission.
Pipeline inspection survey chart

Context
A geophysical pipeline inspection survey offshore Indonesia. Each sheet combines bathymetry, a sonar mosaic with interpreted features and a longitudinal profile.
My part
Data processing and chart production: MBES surface, feature compilation and the alignment sheet layout.
Deliverables
Alignment charts as DWG and PDF. Names, coordinates, IDs and the title block are removed here.
MBES processing
Cleaned multibeam surface gridded at 1 m, with depth shown in colour and hillshade.
Branch site selection
Hexagon scoring of population, competitors and access for a multi-branch clinic network.
GIS mapping projects
Five studies from my GIS portfolio. Select a map to enlarge it.
How I work
The same five steps on every job, whether it is a multibeam dataset or a site study.
Scope
Objectives, specification, data and expected deliverables.
Plan
Data needs, tools, checks and milestones.
Process
Survey processing or GIS analysis.
Quality control
Consistency, completeness and requirements.
Deliver
Agreed outputs, documentation and handover.

About
I'm a hydrographic surveyor and data processor based between Bandung and Jakarta. My work links field acquisition to deliverables a client can use.
That means clean bathymetry, consistent charts and structured data. Alongside survey work I take on GIS projects, from site selection for growing businesses to environmental mapping.
I value a clear scope, checked data and plain communication with the project team.
