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.

Complexity

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.

Approach

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.

Services

Consultancy

GIS Specialisten provides consultancy and project management for the professional support of the design, implementation and management of GIS. Our experts can set up and maintain a structured GIS department, including the work of the (permanent) employees.

Data analysis is the process of finding answers to different themes using raw data. In a statistically substantiated manner, answers are given to a wide range of issues. The data analysis contributes to decision-making and image formation of a question, but also has a role in marketing, for example. The results of data analysis are displayed in different ways. With geographic data this is often in the form of a map, but these can also be dashboards with KPIs, graphs or reports

Data is now widely available. The quality and shape is very varied. During a data conversion, data is inspected, cleaned up, transformed and modelled in order to continue to work in the most efficient way. When converting data, it is sometimes necessary to combine data sets to enrich them. In this way, all valuable information can be retrieved from the data.

Good, systematic storage of data ensures that data is always correct and available. This is of great importance in every (business) process. Important elements of data management are managing metadata, ensuring the right back-ups and designing the most efficient data models. Data and database management ensures that everyone always has the right information. This data can then be interpreted unambiguously and contributes to the quality of data analyses.

For GIS to perform to a high standard with wide availability, a stable IT architecture is important. A well thought out GEO-ICT architecture ensures that your GIS performs optimally and can grow with you in the future. In addition, matters such as security and privacy are of great importance for protecting the data. Depending on the purpose and wishes, a local architecture, a cloud based solution or a hybrid environment can be chosen.

To be able to use new technologies and to get involved in a dynamic world, it is necessary to migrate to newer software versions. It is important that all different components of the GIS continue to work together. With a data migration it is important not to disrupt ongoing (business) processes. After a migration, a form of information or knowledge transfer is often required to ensure that everyone benefits from the new situation.

Coordination and supervision is of great importance for complex GIS or GEO-ICT projects. An appropriate mix of substantive knowledge and process, and management knowledge, combined with techniques such as Scrum / Kanban (Agile) and Prince2, provide an optimal environment for the success of the GIS project.

The world around us is changing and so too are the tools we work with. The applications and the platforms on which this is running regularly renew. In time with the right versions, these changes ensure that data, software and environments stay tuned and perform optimally.

Specific software is required when performing detailed GIS tasks. What cannot be done with standard functionality can be customised. Depending on the requirements and wishes, this can be configured with open source or commercial software. In both cases, stable software is provided, which works quickly and intuitively. All software is provided with clear accompanying documentation where necessary.

To ensure that ready-made software packages function optimally, a correct configuration is important. This works in two directions; on the one hand, a user must immediately have the most relevant tools available; on the other hand, the software must be configured correctly in order to make the most of all sources.

Before new software can be used, it is necessary to undergo extensive testing. The GIS software must be compatible with the environments used and be able to work well with other geographical tools so that they can handle the data in the right way. Software test management prevents surprises that disrupt the production process.

Periodic monitoring of performance is important to ensure that the GIS continues to function optimally. The entire range of GIS software, hardware, databases, data processing and the execution of test cases is discussed. Performance tests enable an organisation to identify problems before they disrupt daily work. By proactively testing and monitoring the GIS remains healthy.

Data can be made available anywhere through hosting. By data hosting you do not need a complete GIS system yourself. When hosting data, the data is served from a local or cloud-based GIS server for the end applications. The security, management and maintenance lies with the host, which removes overhead for the user.

By taking care of GIS courses and customised training, everyone gets the maximum return from the GIS. After attending a course, everyone speaks the same language and all functions are used. For temporary projects, knowledge transfer takes place through documentation, possibly supplemented with presentations.

Data collection and aerial photography using drones and remote sensing ensure that data remains up-to-date and can be enriched. Remote sensing data has many applications and can, for example, be used for creating 3D point cloud data to give analyses an extra dimension. Well-trained operators in possession of all the right permits can provide accurate data.

Recruitment and Secondment

GIS Specialisten likes to arrange the right person in the right place, with the right GIS knowledge, experience and mentality. To achieve this, we strive for a personal approach: informal, but professional. As a result, we get to know the person behind the specialist better in our selection interviews, with which a good match between client and specialist is achieved. A specialist in the right place performs better! Our clients have the choice of various types of employment. For example, specialists can be deployed on a freelance or secondment basis for both short-term and long-term use. In addition, it is possible to hire someone permanently.

Development

Due to the strong dynamics in the field, it is important to keep the knowledge up-to-date. That is why GIS Specialisten ensures that all specialists are kept up-to-date on all developments in the field through training, workshops and further training. In this way, we can also optimally match the client’s request to the supply.

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.
