SIIS will hold a booth at upcoming ISRS 2018 in Pyeongchang, Republic of Korea.

*Date: May 9 - 11, 2018
*Venue: Alpensia Convention Center
*Booth No.: 2


SIIS team attended GeoSmart Asia and Locate 2018 in Adelaide, Australia hosted by Geospatial Media and Locate from 9th to 11th of April. It was our first time to attend an exhibition in Australia, so our team had opportunity to meet satellite imagery users and sales partners in Australia. Our team had meetings with out exhibiting partners in the exhibition and found potential sales partner in that region. We have participated exhibitions by Geospatial Media regularly, but it was our first time to attend Locate exhibition. Many australian users seem to attend Locate exhibitions often.

KARI(Korea Aerospace Research Institute) has been releasing KOMPSAT Imagery Quality Report since May, 2016. We have been sharing reports on our website and newsletter every other month. The report of February and March 2018 shows information of KOMPSAT-2, 3, and 3A. It includes location accuracy, ground resolution, etc. The location accuracy of KOMPSAT satellites have improved a lot from the designed specification.

In Costa Rica space technologies, have been recently developed through projects such as Ditsö (program for scientific research in microgravity conditions) and Irazú (the regions first Nano satellite); both promoted by the Central American Association of Aeronautics and Space ACAE.
As an instrument to promote economic development through technology transfer from space to leading industry and sectors, a group of ACAE members started the project DIT Space (design, innovation and technology for space).
DIT Space distributes KOMPSAT constellation satellite images for Central America and the Caribbean, through a partnership with SI Imaging Services SIIS, exclusive worldwide distributor of Korea Aerospace Research Institute KARI, satellite images.
All images are offered with basic processing by our team of professionals, according to customers’ needs. Images are processed using PHOTOMOD® software, which DIT Space distributes in the region through partnership with Racurs.

Application Note

SI Imaging Services website

Sea ice motion and deformation have generally been measured using low-resolution passive microwave or mid-resolution radar remote sensing datasets of daily (or few days) intervals to monitor long-term trends over a wide polar area. This feasibility study presents an application of high-resolution optical images from operational satellites, which have become more available in polar regions, for sea ice motion and deformation measurements.The sea ice motion, i.e., Lagrangian vector, is measured by using a maximum cross-correlation (MCC) technique and multi-temporal high-resolution images acquired on 14–15 August 2014 from multiple spaceborne sensors on board Korea Multi-Purpose Satellites (KOM
PSATs) with short acquisition time intervals. The sea ice motion extracted from the six image pairs of the spatial resolutions were resampled to 4 m and 15 m yields with vector length measurements of 57.7 m root mean square error (RMSE) and −11.4 m bias and 60.7 m RMSE and −13.5 m bias, respectively, compared with buoy location records.

Guinea-Bissau is a sovereign state in West Africa. The terrain is mostly consisted of low coastal plain with swamps of Guinean mangroves rising to Guinean forest-savanna mosaic in the east. The average rainfall for Bissau is 2,024 millimeters (79.7 in) although this is almost entirely taken during the rainy season between June and October. The economy depends mainly on agriculture; fish, cashew nuts and ground nutsare.
