In-house GIS team vs outsourced consultant: how to decide
Most organisations that work with spatial data hit this question eventually. Do we hire…

Enterprise-grade geospatial intelligence built around your business
Strategic geospatial expertise for property, energy, infrastructure, and local authorities
Book a free consultationMany organisations already own valuable spatial data - property records, environment datasets, infrastructure assets - without fully realising its strategic potential.

The problems that stop GIS projects
We've solved these seven problems numerous times. Yours might not look exactly like the next organisation's, but the pattern is usually there.
Common GIS challenges we solve
Data we can't trust
Incomplete records, inconsistent formats, duplicate entries. Before anything else, you need to know what you've got.
We audit your data, identify issues, and rebuild trust with validated, clean records.
See our audit process →Platform uncertainty
ESRI, QGIS, Postgres custom, or something else? The right answer depends on your team, data, and roadmap.
We evaluate your options against your specific needs and help you choose the right stack for your data volume and team.
Read our tech evaluation →Low adoption
The new system isn't replacing the old spreadsheet. Workarounds everywhere. The problem isn't the tech.
We redesign workflows and train teams so they actually use what you've built.
Explore our approach →Need to scope first
You know something has to change but can't write the brief yet. You need an honest audit, not a sales pitch.
We run a scoping engagement that clarifies requirements and builds a solid brief for your project.
Learn about scoping →Something needs building
An app, an analysis, a plan. The thinking is done. You need a team that can deliver it precisely, on time.
We deliver custom solutions built to your exact specs, tested thoroughly, and ready for your team to maintain.
See what we've built →Need expertise
Data migration, analysis, optimization, training, APIs, compliance, or ongoing support.
We bring specialized skills to the exact challenge you're facing, when you need them.
Explore our services →Integration challenges
Your GIS exists in isolation. Sales, operations, planning. They need access but can't get it. Silos everywhere.
We connect your GIS to the systems your team actually uses every day. Data flows where it needs to go.

Team adoption
Why most GIS projects fail (and how we avoid it)
Build the wrong tech and strategy fails. Get the strategy wrong and adoption fails. Forget adoption and you have an expensive tool nobody uses. We weight our work to the thing that actually breaks: making your team want to use it.
Let's map out your next move
A one-hour conversation gets us from "we're not sure where to start" to a roadmap. Whether you want to scope a project, understand your options, or move straight to a proposal: let's start the conversation.
Schedule a callNot sure if we're the right fit?
We're best suited for teams with spatial data at meaningful scale who need both technical depth and strategic clarity.
If that's you, let's talk. If not, we'll point you toward better options.
