Practical guide to open source GIS and modern GIS in your organisation: QGIS, PostGIS, web maps, migration, and operations. Where a commercial platform like GeoApps fits alongside OSS, in plain language.
Modern GIS combines web maps, trustworthy data, and links to your processes. Open source (such as QGIS and PostGIS) fits well. Expand each step in the roadmap below for the full work list and deeper detail. A GIS stack is not free to run: updates, security, and support still need owners.
In this recording we discuss how organisations use modern GIS and open source, as a complement to the roadmap below.
Short reference table for the roadmap. Your setup may differ.
| Part | Example | What for |
|---|---|---|
| Desktop workbench | e.g. QGIS | Make maps, answer spatial questions, and check data before you share it. |
| Data storage | Often PostgreSQL + PostGIS | Where the authoritative map layers live: reliable, searchable, and connectable to other systems. |
| Online maps | e.g. GeoServer or similar | So maps work in a browser or apps, not only on the specialist’s PC. |
| Keeping data fresh | Scripts or schedulers | Repeatable steps to refresh data from source systems on a schedule (less manual work, fewer mistakes). |
| Web & access | Map in site/portal, links | Where colleagues and citizens see the map, and where you connect sign-in and other software. |
Twelve steps from vision to scale. Steps 1 to 8 combine a short work list with deeper detail: open a step to see everything. Then migration, data, publishing, automation, roles, training, governance, and advanced use cases.
Work list (short)
In plain language, write down why you want open source (for example: less dependence on one vendor, easier links to other systems, or more control over data). Decide how far you want to go: maps on the PC only, maps on intranet or website as well, or a broader map-and-data setup.
Deeper detail
Do not start with tools: start with the question: what must GIS deliver?
Think about:
Output: A short GIS vision with concrete use cases.
Work list (short)
Make a simple list: which programs and contracts, where map files live, who makes maps, and who helps when something breaks. That quickly shows where it hurts.
Deeper detail
Map what runs today and where it hurts.
Inventory:
Output: Current architecture plus pain points.
Work list (short)
You do not have to replace everything at once. Many teams start with QGIS and a central place for map data; online maps for colleagues and citizens come later. Choose what fits your people and IT agreements, and what you can maintain.
Deeper detail
Choose what you need per layer.
Examples per layer:
Output: Target architecture.
Work list (short)
Open source brings freedom and responsibility: who may do what, which passwords must never be shared, and how do you back up? Agree this with IT and privacy, so no one has to guess later.
Deeper detail
Decide what moves, is rebuilt, or is connected. Start with a pilot instead of everything at once.
Decide:
Output: Phased migration plan.
Work list (short)
Pick one concrete example (one map product or one workflow). Train the people who will run it, and show them where to ask questions. If it works, you expand.
Deeper detail
Install QGIS LTR and configure a reusable baseline.
Output: A working QGIS baseline environment.
Work list (short)
Converting old files often takes longer than installing new software. Work in small steps, spot-check boundaries and labels, and record who keeps the “right” version.
Deeper detail
Avoid scattered, siloed data.
Output: A central, reusable geodata foundation.
Work list (short)
Open standards make it easier to switch vendors later or share data. In the Netherlands you often use national feeds (such as PDOK); note where they fit and who owns them.
Deeper detail
Make maps usable for people who are not GIS specialists.
Output: Policy staff, project leads, field teams, and citizens can use geo without QGIS: first online GIS applications.
Work list (short)
Software ages: plan once a year (or more) which versions you upgrade and how you roll back if something breaks. Small regular care prevents big crises.
Deeper detail
Which manual GIS tasks can you automate? Use FME, GDAL/OGR, scripts, or platform capabilities.
Examples:
Output: Less manual work, more reliable processes.
Deeper detail
The GIS expert does not disappear; the role evolves.
Output: A clear operations and roles model.
Deeper detail
Not everyone needs to become a QGIS power user.
Output: Adoption plan plus training.
Deeper detail
Make explicit choices about open source.
Output: Written open source governance agreements.
Deeper detail
After the basics: grow toward strategic applications.
Output: GIS as strategic information supply, not only as a map tool.
Aligning briefly as a team (or with your partner) first keeps a call with us focused. Then pick a time below to walk through the roadmap, modern GIS, open source, and how GeoApps could fit your situation.
