Geospatial data preparation

Geospatial Data Services

Location, road, boundary and geographic datasets, delivered in the projection, schema and format your stack expects.

Population grid aggregated for a metro study areaSparseDense

Overview

Most spatial problems are data problems first

Analysts lose more time to broken geometry than to analysis. Self-intersecting polygons, mismatched projections, boundaries that do not tile, road networks that look continuous but are not connected at the junctions: none of it is visible on a screenshot, and all of it changes the answer.

We prepare geospatial data so that the first thing you do with it is analysis, not repair. Geometry is validated, topology is checked, projections are stated explicitly and coordinate precision is appropriate to the source.

Where a national mapping agency or an open dataset already publishes what you need, we say so and help you use it. Paying for data that already exists in the public domain is the most common avoidable cost in this field.

The same data, mapped

A static preview rather than an embedded map SDK, so the page stays fast. Interactive maps are built on request as part of a visualization project.

Scope

Datasets we prepare

Layers are delivered individually or as a coherent, joined package.

  • Administrative boundaries

    Countries, regions, municipalities, census units and postcode areas, cleaned so they tile without gaps or overlaps.

  • Custom zones

    Trade areas, delivery zones, sales territories and catchments built to your definition.

  • Road networks

    Routable geometry with classification, one-way flags and validated junction connectivity.

  • Point layers

    POIs, assets, stops or events as validated point features with attributes.

  • Building and parcel footprints

    Polygon layers with area, and height or storey counts where the source provides them.

  • Land use and land cover

    Classified polygons for context, constraint mapping and suitability analysis.

  • Population and demographic grids

    Statistical values disaggregated onto grids or apportioned to your custom zones.

  • Isochrones and catchments

    Drive-time, transit-time and walking-time polygons generated on a road network.

  • Address datasets

    Geocoded address points with match quality and confidence recorded per record.

  • Raster products

    Density surfaces, interpolations and derived grids at a stated resolution.

Output formats

Delivered the way your stack expects

GeoJSON
EPSG:4326, right-hand-rule compliant, suitable for web mapping and APIs.
Shapefile
Delivered with .prj, .cpg and a field name mapping, since shapefiles truncate long names.
GeoPackage
Single-file, multi-layer delivery with preserved field types and no name limits.
PostGIS
Direct load with spatial indexes and geometry constraints already applied.
CSV with WKT
For tools that expect tabular input but still need geometry.
Vector tiles
MBTiles or PMTiles for fast rendering of large layers in a browser.

Sample dataset

What you actually receive

Sample project data. Every layer states its coordinate reference system, its source type and its vintage, because mixing those silently is how spatial analysis goes wrong.

This service on a real project

Sample projects built on this service, with the numbers they produced and what each one settled.

Heatmap AnalysisGIS AnalysisMap Visualization

Urban Heatmap Data Analysis

Turning a scattered point dataset into a normalised density surface that separates real activity clusters from population artefacts.

Input records
48,600
Records corrected
9.1%
Hotspots confirmed
2 of 5

What it showed

  • Central had by far the largest raw count and by far the largest visual hotspot, but ranked third on activity per resident. The original map had been describing population distribution, not activity.
  • Harbourside, which barely registered on the unnormalised map, was the strongest genuine hotspot at 99% confidence. It has a small residential population and a high concentration of activity, precisely the pattern raw-count heatmaps hide.

POI DataData CollectionMarket Research

POI Data Analysis

Building a comparable category census across five metro areas, and the standardisation work that made the comparison valid.

Raw records

Unique POIs

Category labels
14 → 1

What it showed

  • Ranked by absolute count, Metro A led by a wide margin. Ranked per capita, it placed third, and the two markets the team had considered marginal turned out to be the most densely served.
  • Chain share varied from 17.9% to 51.4% across markets that industry commentary had treated as broadly similar. That spread became the central finding of the research rather than a footnote.

How it works

Five steps, every project

  1. Step 01

    Tell us what data you need

    Describe the study area, the layers and the tools the data has to work in.

  2. Step 02

    We define the data scope

    We identify sources, licences, projections and the schema each layer will use.

  3. Step 03

    We collect and process the data

    Layers are acquired, reprojected, clipped to the study area and given consistent field names.

  4. Step 04

    We validate the dataset

    Geometry validity, topology, connectivity and attribute completeness are all checked.

  5. Step 05

    We deliver the final result

    A documented package with a layer manifest, CRS notes and licence attributions.

Quoted on feature counts, the number of layers, source complexity and validation depth. Tell us the layers and coverage you need and you get a fixed price against a written scope.

FAQ

Questions we get asked

What is geospatial data?

Any data with a location attached: a point, a line, a polygon or a grid cell tied to coordinates on the Earth. What makes it geospatial rather than tabular is that distance, containment and adjacency between records carry meaning.

Which coordinate systems do you work in?

We deliver in EPSG:4326 by default and reproject to whatever your workflow needs, including national grids and local projected systems. Any measurement of distance or area is done in an appropriate projected system, never in degrees.

Can you work with open data such as OpenStreetMap?

Yes, and we recommend it where it fits. We extract, clean and validate it for your study area, and we include the required attribution. Where open data has known gaps for your use case, we say so and propose how to fill them.

Can you build custom boundaries?

Yes. Trade areas, delivery zones, sales territories and catchments can be built from drive times, postcode groupings, population targets or rules you define, and delivered as clean, non-overlapping polygons.

Do you handle large datasets?

Yes. National road networks and multi-million-feature layers are handled with tiled processing and delivered as GeoPackage, PostGIS or vector tiles rather than shapefiles, which are not suited to that size.

Can you fix a dataset we already have?

Often the fastest option. We run a validity and topology audit, report what is wrong, and repair geometry, projections, field types and joins in place so your existing analysis keeps working.

Have a specific data requirement?

Tell us the geography, the fields and the cadence you need for geospatial data. You get a scoped plan, a sample and a fixed price before any work starts.
