GIS Mapping delivered as scalable offshore support.
GIS-to-CAD conversion and utility asset mapping — ArcGIS and QGIS data reconciled into coordinate-true DWG for distribution design. Built for engineering managers scaling drafting capacity without adding headcount: A cost-effective, scalable offshore team that works to your standards and delivers overnight, so your licensed staff review rather than draft.
GIS-to-CAD conversion is the second workflow teams most often move offshore, because it is high-volume and rules-based. We reconcile ArcGIS and QGIS parcel, asset and network layers into coordinate-true DWG aligned to your project datum, with GIS attributes mapped to your CAD layer schema rather than flattened to geometry.
Because the conversion follows a defined attribute-to-layer mapping, it scales cleanly across a large data set without losing fidelity. We check spatial accuracy against the source before delivery, so the base your designers build on is true to the record, not a redrawn approximation.
| Metric | In-house team | Spanex Engineering |
|---|---|---|
| Cost efficiency | Fixed salaried capacity, paid whether the queue is full or not | Cost-effective per-project support — pay for the work, not idle time |
| Turnaround | Bound by local working hours | Overnight production against your time zone; review starts your morning |
| Scalability | Hiring and training lead time to add capacity | Scale a run up or down by the project, no hiring |
| Standards | Your CAD standard and code | Your CAD standard and code — we adopt yours, not ours |
| Quality control | Reviewer often also the drafter | Independent lead review on every package before release |

Common questions
Which GIS platforms do you work from?
ArcGIS and QGIS. We reconcile parcel, asset and network layers into a coordinate-true CAD base aligned to your project datum.
Do you preserve attributes in the conversion?
Yes. GIS attributes are mapped to your CAD layer schema so data survives the conversion rather than being flattened to geometry.
Why work with Spanex Engineering for gis mapping?
A cost-effective, scalable offshore team that works to your standards and delivers overnight, so your licensed staff review rather than draft.
Which GIS formats can you convert to CAD?
ArcGIS geodatabases and shapefiles, and QGIS layers. We convert to DWG or DGN aligned to your datum, preserving attributes through a mapping to your CAD layer schema.
Do attributes survive the GIS-to-CAD conversion?
Yes. We map GIS attributes to your CAD layer and block schema so asset data carries into the drawing instead of being lost when geometry is exported.
Can you convert legacy as-built records as well as live GIS?
Yes. We convert legacy GIS and scanned as-built records into coordinate-true, standards-compliant CAD your team can design from.
