The output of GIS Specialisten is used efficienty in, for example sustainability and policy choices.
Geographical Information Systems

GIS takes an increasingly prominent role in the processes of organisations. This is not surprising, because only with GIS can spatial relationships and patterns be clearly mapped out. Large amounts of data from various sources are processed, analysed, interpreted and visualised in a GIS. The result is usually a clear representation of a situation, problem or trend and in a universal language with an understandable message for the target group.


However, GIS is also complex. Both the implementation, management and use of GIS requires specialist knowledge and expertise. In addition, the field is constantly developing, ensuring that yesterday’s knowledge is not enough to meet the challenges of tomorrow. This makes it difficult for organisations to have and maintain all knowledge in-house. GIS Specialisten can fill this burdening role for organisations. In the form of consultancy, secondment and professional support, we therefore gladly make a valuable contribution to (government) organisations and companies.

Working method GIS Specialisten

In the approach of GIS Specialisten, the match between specialist and client is central. We are only satisfied if the right person reaches the right place within an organisation. That is why GIS Specialisten combines an informal, personal approach with a professional attitude. Thanks to this approach and years of experience, GIS Specialisten is a reliable partner with an established position in the geographic sector.


The focus of GIS Specialisten is proces-, customer oriented and technically innovative. Our core activities are divided in the specialism below.

The amount of data generated, captured and made available today is growing hand over hand, resulting in insights that power the creation of countless new business opportunities. The drawback is that processing, storing, correct interpretation and dissemination of this data is increasingly becoming a challenge.

At GIS Specialisten, we can support you in the correct visualization of your spatial data through analogue or interactive web maps. We will perform the necessary spatial analysis and extract the geoinformation that can support your decision making, programs, monitoring and evaluation.

The first step is often to do an ETL (Extract, Translate and Load). This helps us prepare, process, and present GIS data in the best form. The structured approach of the ETL makes it easier to identify meaningful insights, visualize them in a suitable manner and convey them to potential users. To choose the applications and software necessary during the ETL, we use an objective approach. Our portfolio includes ESRI, Safe (FME), Hexagon and open-source applications such as QGIS and PostgreSQL. We always select the applications that are the most relevant and fitting for your project and your organization.
In every GIS project, sharing data and presenting results is critical in conveying the information to the target audience. GIS Specialisten supports you in this essential step by designing and implementing custom dashboards, web GIS applications or software plugins. Together, we clarify your requirements and end goal and make an educated choice of development and configuration tools. This way, we can ensure that our solution fits your existing workflows.

Are you looking for an application in which certain acquisition, processing and dissemination steps can be automated? Our developers will discuss your requirements with you and will create a custom application that does just what you need.
A proper IT infrastructure is of key importance for any automation project. To set your infrastructure up right, you need to make decisions about a range of elements. How will you connect and secure the servers? What kind of storage, database and applications do you need? Do you want to host your environment on bare metal or use cloud virtualization technology such as containers?

GIS Specialisten offers you a clear overview of all you need for your GEO-ICT infrastructure. We look at security, performance and scalability for geospatial solutions. Once we identify your requirements, we will plan and draw out the steps together and implement the best solutions that are available today.

If you do not have on-premise IT availability, we can offer GeoService.Cloud for hosting and management.
GIS Specialisten also helps companies in various application domains by deriving actionable insights from earth observation data. We have expertise in using both drones and satellites for remote sensing to support you in reaching your business targets.

We combine multiple sources of geospatial data, both open source and commercial, and we use state-of-the-art methods and techniques to create products and services that precisely and accurately address your requirements.

Our team has experience with both Optical and LiDAR remote sensing data. We use machine learning and cloud services to find and process the data best suited to the project. The result: timely, objective, and transparent information that serves your needs.
Our mission is to offer innovative geospatial solutions to support our customers’ operations and workflows: during planning, implementation, monitoring, evaluation and beyond. To be able to do that at the high level we want to, we heavily invest in knowledge exchange. Our team consists of highly skilled individuals who are specialized in different domains. In addition, we have close working ties with experienced partners and organizations in the geospatial industry, a network of talents that make our co-creation proficiency even stronger.

Once we understand your needs, we will make sure you receive the optimal support from us. Depending on the problem at hand, we can provide secondment, consultancy, project management support, recruitment or training.
At GIS Specialisten, we never stop learning. Science and technology are evolving around us at breakneck pace, so we invest in staying up to date with the latest developments. Moreover, we believe that a successful team requires continuous growth – and this can only be achieved by following a life-long learning approach.

For that reason, the research and innovation we do is not limited to a single department or a limited number of people. Innovation is how we grow, so it is a part of our work culture. We are curious and motivated people, driven to discover creative ways to develop time- and cost-effective geospatial solutions.
Integrate IoT with GIS

The government invests more and more in Smart Cities. Various Internet of Things (IoT) sensors with LoRa technology collect relevant live data of different locations, and send this to the open source platform of The Things Network (TTN). This platform serves as a central place for all sensor data and standard encrypt the data, wherefore only the owner of the sensor receives the secured data. The data could be used to perceive particular trends or changings.

Through collect different types of sensor data (for example temperature or air quality) you could analyse geographic relations (based on location). Most (semi-) government agencies have a GIS system, because of this the combination with IoT is interesting.  We could  access the data from TTN via various protocols to a GIS system or database. This can be platform independent. It doesn’t matter if a GIS system uses an open source application or for example ArcGIS Enterprise (ArcGIS Online/ArcGIS Server).

At GIS Specialisten we believe in the power of sharing information to foster innovation. Do you want to know more about the possibilities of IoT and GIS you could give us a call: +31 (0)857 325 825 or via contact

Skylab is our partner for delivering the LoRaWAN gateways and/or LoRa IoT sensors. For more information about this, go to this website

“De spatial analyses functioneren niet goed in de QGIS opensourceapplicaties”, “de LiDAR data is niet goed geïmplementeerd in ArcGIS”. Spatial en LiDar? “Huh, zeg dat nog eens?”.

GIS is een voor vele mensen onbekend vak. De projecten kunnen complex zijn zonder enige kennis binnen het GIS-domein. Vandaar dat de manier van communiceren essentieel is om de juiste boodschap over te brengen. Aan mij de taak om hier een handje bij te helpen binnen het GIS Specialisten team.

Mijn naam is Paulien van Merrienboer, 23 jaar oud en sinds 2 januari 2020 werkzaam bij GIS Specialisten als Marketing & Communicatie Specialist. Ik ga mij richten op de digitale en geprinte uitingen, de events, Social Media en alles wat daarbij komt kijken. In 2017 heb ik mijn opleiding Corporate Communication behaald. Ik vond vooral het branding gedeelte interessant. Je merk sterk op de markt zetten en de juiste doelgroep(en) aanspreken door bijvoorbeeld gebruik van online en offline communicatie.

In 2016 heb ik stage in Valencia gedaan bij een online reisbureau, hier heb ik Spaans geleerd en veel ervaring opgedaan op gebied van marketingcommunicatie. Andere relevante werkervaring heb ik de afgelopen 1,5 jaar opgedaan als Content Officer, waar ik voornamelijk bezig ben geweest met het invullen van een website.

In mijn vrije tijd houd ik van reizen, tekenen en met familie en vriendinnen leuke dingen doen. Zo kom ik net terug van een 3-weekse reis door het mooie Colombia.

Vragen over communicatie of marketing gerelateerde onderwerpen? Of samenwerkingen op dit gebied? Neem dan contact met mij op via en wie weet drinken we binnenkort een kop koffie!

Ontmoet de rest van het team, of kijk hier of er nog een passende vacature voor je is.

Power of GIS
A GIS (Geographic Information System) is a system for storing, managing, processing and visualising geographical data. This data usually comes from various sources and can be very different in nature. One property has all the data in common: they are linked to a location on earth. This makes it possible to accurately map themes and trends of a specific area in a GIS. This creates relationships and patterns that otherwise can never be discovered. The applications are very diverse: from the determination of the location of facilities to the identification of risk and problem areas. Analysis can be performed on international, national, regional or even at neighbourhood scales. The strength of GIS lies in combining and presenting data on a map, so that you can provide insight into complex information at a glance.
