What do you use GIS for?
I have worked on different GIS projects at different scales and have built custom analytical systems to answer a variety of questions. While I strongly believe in the value of data, I have increasingly started wondering about the actual added value of some of these complex approaches.
In many cases, especially in biodiversity conservation, the results often seem very similar to what an experienced professional could have concluded simply by knowing the landscape, the ecosystem, and the problem. It is mostly the same and repeating itself.
For example, in Switzerland, where I often work in familiar landscapes, many conservation questions eventually come down to solutions we already know: restoring ecological structures, planting more hedgerows, improving the management of existing green infrastructure, reconnecting habitats, or changing maintenance practices.
Of course, GIS can build sophisticated systems to identify priorities, optimize interventions, estimate costs, and compare scenarios. But then the reality is often that a landowner does not agree, a project is not feasible, or the theoretically optimal location is not the right place to implement something. Sometimes a more practical approach based on local knowledge and relationships would have achieved more.
This makes me wonder where the real value of GIS lies.
Maybe this changes when working at larger scales, across different ecosystems, or in regions where local expertise is limited. But when you know a landscape well, it sometimes feels like experience and ecological understanding can already provide many of the answers.
I know maps are important to communicate, but for me, that's more in the visual communication category. Because of this, I'm now dabbling in modeling microclimates.
So I am curious:
What do you use GIS for, and where do you see its biggest benefits?
Is GIS mainly a tool for discovering new insights, or is its greatest value in supporting decisions, communicating evidence, and making expert knowledge more transparent and scalable?
