Development of Landsat-8 ARD Products for User Service in Indonesia

Abstract

Along with the times and technology development, the number of satellite images produced is increasing and diverse, both in terms of spatial and temporal resolution. In addition, in the last few years, LAPAN has done a mosaic of Landsat data for 16 days. The availability of extensive satellite data makes users desire data ready to use without initial processing to save time and costs. Furthermore, the medium resolution image has a comprehensive enough coverage for applications in the forestry, agriculture, plantation, and marine sectors. Therefore, the need for medium resolution Analysis Ready Data (ARD) increases. The available ARD data has been through the initial processing, including ToA and BRDF corrections. The existing Landsat-8 ARD does not cover Indonesian territory. The Landsat-8 ARD for the Indonesian region was first produced and introduced in this paper. Moreover, the development of ARD data quality is carried out by adding a topographic correction process, and image cropping become tiles with a size of 1-degree x 1-degree, which can be run automatically. This processing system produces ARD Landsat-8 to meet user requirements effectively and efficiently. These advantages are obtained because the pre-processing data load for the user has been reduced, and the user can immediately use the data according to the required scope. The software for making ARD Landsat-8 has been recognized as Intellectual Property Rights. Moreover, ARD Landsat-8 for Indonesian territory has been continuously utilized by the Indonesian Ministry of Environment and Forestry and the Indonesian Ministry of Agriculture.
