Delivering geospatial information with minimum latency

It is often critical to deliver geospatial information to users with minimum delay. For example, during a flood, water level measurements need to be delivered to the appropriate authorities as quickly as possible. Other scenarios include the measurement of environmental pollutants or the monitoring of moving objects (e.g., geofencing).

Conventional communication patterns in spatial information infrastructures rely on a request-response pattern – client applications need to check regularly if a server offers new data. This results in latency and unnecessary server load. Our team has comprehensive experience with technologies to efficiently deliver geospatial information in near-real time.

We help answer typical questions

• How to minimize the delay of data delivery?
• Which technologies are suited to build near-real time spatial information infrastructures?
• How to ensure the reliable delivery of geospatial data?
• How to document successful information delivery?
• How to implement access control for datastreams?
• How to ensure efficiency and scalability?

We offer:

Requirements analysis

Architecture design

Evaluation of software building blocks

Prototyping

Practical implementation

Strategies for operational deployment and use

Ready-to-use open source software components

Customization of existing software packages
