New equipment and increasingly sophisticated sensors generate enormous amounts of geodata every day. With the GeoRocket software, researchers at Fraunhofer IGD present a cloud-based store to take on the increasing quantity of geodata and use it to help predict natural disasters.
(Darmstadt) As science and technology advance, increasingly accurate data is being collected in every field - including data that provides information on a certain location or geographical area. This geodata is growing in volume and complexity to the point where it is unmanageable. With GeoRocket, the Fraunhofer Institute for Computer Graphics Research IGD offers a geodata store that responds quickly and flexibly to the increased demand.
High-precision and complete survey data can only be used profitably when it is easily available anywhere. It then makes a valuable contribution to, for example, risk analysis in earthquake-prone regions. Aside from human factors, landforms can also promote the occurrence of natural disasters. To this end, satellite images, ground studies and computer-generated 3D landscape models are available to conduct hydraulic simulations - allowing the calculated mass of water from high forecast precipitation and its downslope flow path to be visualized. The storage required for all this information is immense - the more resolved and true-to-life the relief of the land is mapped, naturally the more realistic the prediction of the path of a landslide. In order to meet the mass of geodata with its enormous storage requirement, a suitable technical solution is needed.
The GeoRocket geodata store is cloud-based, allowing it to work very quickly and be accessed with ease. The free Open Source program responds quickly even with large amounts of data and multiple simultaneous queries. Its microservice architecture dynamically scaled the needed performance to shifting factors, such as data volume being transmitted or the number of users and processes running. Even real-time searches for geodata or attributes, layers, assigned tags, etc. is extremely fast thanks to the targeted output of data in accordance with the search query. The best part: Although the geodata is stored in its original formats, GeoRocket automatically merges the files while they are being used. This type of conversion is vital, since the file formats of the various geoinformation systems are highly diverse.
In addition to the free version, a pro version is available specifically for companies that includes additional functions with its free support, such as an admin area with map display as well as data security features. GeoRocket’s next stage of development will be to output reprocessed datasets in a big data analysis to even better assist geologists, farmers or local agencies in their work.
Fraunhofer IGD will present GeoRocket at the INTERGEO international conference and trade fair for geodesy, geoinformation and land management in Frankfurt am Main, Germany from October 16 to October 18, 2018. At Stand 12.0A.015 in Hall 12.0, a 3D-printed miniature city will illustrate various applications in digital city, planning support and public involvement, environmental monitoring, big data in agriculture and internal security.
