Spatial Data

GIS Mapping and Surveying

Efficient city administration hinges on robust planning, driven by accurate data. Geographical Information System (GIS) has emerged as a vital tool, integrating diverse data sources for informed urban decision-making.

One geodatabase. Every map comes out of it.

Field survey, digitisation and a single project geodatabase underpin every deliverable we issue, so the classification map, the commercial road list and the SDZ boundaries cannot disagree with one another.

The land use classification map is the deliverable a council votes on, so the data behind it has to be traceable: which parcel, surveyed when, classified against which category, by whom.

We build one geodatabase per engagement and generate every map from it. Attribute tables are handed over with the maps, so the district can query its own plan afterwards instead of re-surveying to answer a question.

Where a district already holds spatial data, we reconcile against it rather than replace it, and we record the discrepancies instead of quietly overwriting them.

Field Capture

Every layer starts as a reading taken on the ground.

Positions are observed in the field and reconciled against whatever spatial data the district already holds, rather than replacing it. What the office receives afterwards is one project geodatabase — so a correction made to a boundary is a correction made to every map generated from it.

Deliverables

Districts and municipal corporations that need a spatial record they can keep using long after the plan is delivered.

  1. Field survey and parcel-level data capture
  2. Digitisation and georeferencing of existing records
  3. Project geodatabase with a documented attribute schema
  4. Land use classification map/s
  5. Handover of layers and attribute tables to the client
  1. Base mapSurvey graticule, district extent and hydrology.
  2. Cadastral parcelsPlot boundaries, digitised and georeferenced.
  3. Road networkCarriageway hierarchy and frontage assessment.
  4. Land use zoningClassification carried across every parcel.
  5. Points and annotationJunctions, references and the drawn record.
Next Step

Send the brief. We will tell you what it needs.

A tender reference, a district name or a two-line description is enough to start. We reply with the deliverable set the work would need and what we would want from your office to begin.
