New open-source Python library improves rapid mapping services

In emergency services, rapid response is paramount. ICube-SERTIT’s Rapid Mapping Service provides near real-time delivery of geo-information to help emergency services respond quickly to disasters such as flooding, fires and landslides. A new Python open-source library, called EOReader, speeds up this mapping response by enabling the easy opening of imagery from multiple satellite sensors, both optical and synthetic aperture radar (SAR).

About KOMPSAT-2

KOMPSAT-2 (Korean Multi-purpose Satellite 2), also known as Arirang-2, is an Earth-imaging/environmental Korean satellite which launched on 28 July 2006 and remains operational.

*Mission Specifications*
Orbit Height	685 km
Orbit Type	Sun-synchronous Circular Polar
Repeat Cycle	14 days

KOMPSAT-2 Objectives

KOMPSAT-2 is designed for very-high-resolution (VHR) remote-sensing applications:

Land planning: to detect and identify features smaller than 1 sq.m., e.g. vehicles, street furnishings, roads and bushes
Agriculture: to pinpoint crop or tree diseases
Urban planning and demographics: to locate detached houses
Defence: to describe high-value assets or military sites
Civil engineering: to plan road, railroad and oil pipeline corridors
Surveillance of large scale disasters and their countermeasures
Acquisition of independent high resolution images for GIS
Composition of printed maps and digitised image maps on domestic and overseas territories to users
Continue to support satellite Earth observation activities that were served by KOMPSAT-1.
