Data model Structure asset attributes for publishing.
02
Services Publish layers as web services.
03
Interface Build map, filters and summary panels.

What needed solving Engineering drawings were in CAD with no coordinate system. Assets could not be analysed alongside other spatial data. OBJECTIVES
What the project set out to do Georeference CAD drawings. Convert features into attributed GIS layers. 01
Review Check drawing layers, units and coordinate references.
02
Georeference Align drawings to control points.
03
Convert Convert to features and attach attributes.
04
QA Topology and attribute checks.

What is georeferencing? Assigning real-world coordinates to drawings or images so they align with other spatial data.
Can GIS data be returned to CAD? Yes. Layers can be exported back to DWG or DXF.

What needed solving Flat maps made it difficult for stakeholders to understand terrain. Planners needed to see steep areas and valleys before route and site decisions. OBJECTIVES
What the project set out to do Process a digital elevation model for the district. Create a 3D terrain visualisation with colour relief. Derive slope and terrain layers for planning. 01
DEM preparation The elevation model was clipped, filled and projected.
02
Terrain derivatives Hillshade, slope and aspect layers were calculated.
03
3D scene The DEM was rendered in 3D with vertical exaggeration and colour relief.
04
Visual output Views were exported for reports and presentations.

A clear 3D terrain view of the study area. Slope and hillshade layers for engineering assessment. Visuals that help non-specialists understand the landscape. 3D DEM visualisation Hillshade and colour relief Slope and aspect analysis Presentation-ready views Digital elevation model (DEM) Administrative boundary Reference imagery 3D terrain visualisation images Slope, aspect and hillshade rasters Processed DEM WHY IT MATTERS
Terrain analysis reduces risk in road, pipeline and site planning by revealing slopes and landforms early in design.
What is a DEM? A digital elevation model is a raster where each cell stores ground height.
Why visualise terrain in 3D? 3D views make slopes, valleys and ridges easy to understand for engineers and stakeholders.
Which data sources can be used? Free global DEMs such as SRTM and Copernicus, or high-resolution LiDAR where available.

What needed solving Spatial data was stored in many formats with inconsistent attributes. Repetitive manual tasks slowed the GIS team. There was no documented data standard. OBJECTIVES
What the project set out to do Assess data quality, structure and coordinate systems. Review software and workflows. Recommend practical improvements and priorities. 01
Discovery Interviews and a data inventory established how GIS is used.
02
Quality checks Layers were tested for completeness, topology, attributes and CRS.
03
Workflow review Manual tasks suitable for automation were identified.
04
Roadmap Findings were turned into a prioritised improvement plan.

A clear picture of data strengths and gaps. Recommended data standard and folder structure. A list of automation opportunities. Independent expert review Data quality assessment Automation opportunities Prioritised roadmap Existing GIS layers and databases CAD drawings Interviews with GIS users Audit report Data standard recommendations Improvement roadmap WHY IT MATTERS
A structured review helps teams fix data problems at the source and focus effort where it saves the most time.
Do you need access to our systems? Usually a copy of key datasets and short interviews are enough.
Can you help implement the recommendations? Yes. We can support implementation or train your team.
