caREL

Using Geodata

The INSPIRE directive, which is regulating the foundation for a uniform provision and utilization of geodata throughout the EU since 2021, has created an ideal framework. Existing algorithms from the completed research projects SUN-AREA, WIND-AREA and ERNEUERBAR KOMM! will be merged with the EU-wide standardized geodata.

Creating Algorithms

We intend to develop and deliver an algorithm that allows EU-wide operators from industry, science and administration, software developers, large municipalities and local authorities, planning and engineering offices as well as project developers to perform automated potential analyses to identify the most profitable areas for wind power and solar plants.

Reaching EU Goals

The European Union (EU) has declared its goal of becoming the world's first climate-neutral continent by 2050 through the European Green Deal. The caREL research group is looking for ways to use their expertise to support the achievement of the climate protection goals and the european climate neutrality.

With the "European Green Deal" and its central element, the EU Climate Change Act, Europe is pursuing the long-term goal of becoming the first climate-neutral continent. Identifying the best and most profitable locations for wind power and solar plants is a necessary prerequisite for this

This is a fine example of how the open data strategies of the EU, the federal government and the state of Hesse can pave the way for sensible and necessary projects and what great potential can result from the provision of publicly accessible data free of charge. Therefore, we expressly support open source projects that serve the transfer of knowledge.

-Hessian Minister for Digital Strategy and Development Prof. Dr. Kristina Sinemus

Many countries now offer high-quality LiDAR data as open data via their national geoportals. The caREL algorithm is able to generate high-quality, meaningful results from these data.

Our Work

Processing the results of research

01 January, 2021 · Project Launch

This project starts from the results former projects: SUN-AREA, WIND-AREA & ERNEURBAR KOMM! These were done majorly in Frankfurt, Hesse.

Extension to the European level

1 Octobre, 2021 · Country Selection

The operational area was extended from Germany to Europe. And 5 european countries were selected for the example calculations: Estonia, Belgium, Denmark, Slovenia and Spain Due to the different location in Europe, the selected countries should cover different geographical conditions.

  - Results:
  - -CaREL is a tool to be used in order to perform calculations independently. The Results are not calculated nor will they be available on the website, and no structures are set up for this purpose.
  - -These analyses can be varied by own individual needs.
  - -caREL offers the hope to carry out GIS analyses in the daily work in more detail.
  - -Every used data for the example analyses are available free of charge.

  - Results:
  - - The roads are considered with a buffer in the wind potential analyses, but only the superordinate roads, because of their greater influence on acceptance.
  - - The result data is not available in every desired resolution, for example for smaller areas, but service providers can identify this gap and offer data. CaREL does not offer data.
  - - An algorithm, which is suitable for both analyses solar and wind, could be realized by means of multifunctional surfaces, but not in this transfer project caREL.

  - Results:
  - - Till 2030 all new buildings in the public sector in Estonia should be nearly zero energy buildings.
  - - caREL is a tool with the help of which operators can carry out calculations on their own and to repeat the analyses each year with new data. A governmental organization or NGO can also automatize these calculations, so that it can be refreshed with every new building built.
  - - An Event is planned in Tallinn or at the TalTech where this transfer project caREL will be presented to the Estonian politicians.

  - Results:
  - - The algorithm will not need ArcGIS Pro. A free of charge alternative way to perform the calculations will be provided.
  - - Mainly the data availability influenced the selection of the five pilot countries (Estonia, Spain, Denmark, Slovenia and Belgium) but the geographical location in Europe played a role too.
  - - The analysis results can be individualized or adapted as needed e.g. building outlines or protected areas.
