CAD / GIS & Mapping
Engineering-ready CAD drawings, GIS datasets, digital maps and geospatial deliverables — the form in which survey data becomes usable.
Overview
Survey data earns its value when it reaches the people who design, build and manage — as clean CAD sheets, structured GIS layers and clear maps. BTPL drafts and builds these outputs in-house, from raw field data or from processed aerial products.
We also build GIS and asset-mapping datasets: utility networks, pole and asset inventories, land-parcel layers and spatial databases that integrate survey accuracy with attribute information.
Applications
- Topographic CAD sheet preparation
- Alignment sheets and strip plans
- Utility and asset mapping GIS
- Land-parcel and revenue-map digitisation
- Thematic and planning maps
- KML/KMZ deliverables for review
- Spatial database development
- CAD platforms (DWG/DXF workflows)
- GIS platforms and spatial databases
- Survey data integration tools
How BTPL Performs the Work
Specification
Layer standards, symbology, sheet layout, datum and formats agreed before drafting begins.
Compilation
Survey data drafted/structured; codes mapped to layers and attributes; topology built for GIS data.
Cartographic finishing
Annotation, dimensioning, legends and sheet composition to a professional drawing standard.
Verification
Cross-checks against source data; topology and attribute validation for GIS layers.
Delivery
DWG/DXF, SHP/GeoPackage, PDF map series, KML/KMZ and databases as required.
Accuracy & Quality Control
Drawings follow the agreed layer and annotation standard sheet after sheet; GIS layers pass topology and attribute-completeness checks. What we deliver opens cleanly in your environment — that is the test.

Common Questions
Can BTPL work in our drawing template?
Yes — supply the template, layer standard and title-block convention and drawings are produced to it.
Do you deliver both CAD and GIS from the same survey?
Yes; the survey database is structured once and exported to both, keeping geometry identical across formats.
Can existing paper/PDF maps be digitised?
Yes — georeferenced digitisation with documented accuracy limits inherited from the source material.
