lecture: Delivering high resolution deformation maps with high performance and extensive proc
SkyGeo uses Interferometric Synthetic Aperture Radar (InSAR) by satellites for mapping ground and infrastructure deformation. This leads to maps with millions of virtual sensors, each measuring deformation by time series containing hundreds of measurements. Examples of monitoring infrastructure and managing water injection in oil fields are shown.
The deformation maps and maps with derived information are delivered via a customer portal. The portal tries to provide the rather complex data derived from InSAR together with extensive features to investigate, analyze and further process the data in a user friendly way. As customers are free to use any GIS package as well as the portals own viewer, all functionality is delivered by fully leveraging the (hidden) potential of the open standards WMS, WFS and WPS.
Building the portal proved challenging because of the sheer amount of data combined by the need of live rendering to allow for styling by users and dynamic filtering using WMS dimensions. On top of that, the portal must be alive 24/7, be very secure and required new functionality must be in production within 2-4 weeks. The portal should allow a growth of 10 times per year.
How these requirements can be met using Docker, Nginx, Mapserver, Heron-MC, PostGIS and PyWPS and some custom components will be discussed. Special attention is given to the rich feature set while retaining standards compliance and the encapsulation of mapserver for on the fly mapfile building and easy management of a very large amount of layers.
