Remote sensing imagery in LAPAN has been managed and distributed through many media and device, like CCT, DCRSy, tape, CD, DVD, hard drive. The format is available from Quicklook data (in JPG or BMP), data RAW (in Gtiff or ground station data format). There also exist metadata that bring along in each remote sensing data like Landsat data, SPOT, Radar data, and High-resolution data. From that all collection then it would need some system that can arrange, keep and distribute data in a huge amount of number. Research on metadata structure and standard will be required in managing a large number of remote sensing data. Types and formats from those remote sensing data will be various but the raster format which most widely used is GeoTiff. Metadata for every raster data format is already standardized following the rule of ISO 19139 and 19115. SPACeMAP is a new web catalog system that uses the simplest and latest raster data format for displaying the mosaic image, data processing result, data raw format and etc. The structure of raster data format (like Gtiff and ECW) is very flexible although the format needs certain criteria. Metadata also treated the same as raster format, this treatment hopefully will minimize the error.
The development of information systems in human life along with the of human civilization itself until finally getting to know the term information technology. Pay attention to the development of such information, we will study briefly the history of information technology in an effort to get the integrity of science and knowledge about information technology. History of technology we can divide into prehistory , past history, and modern times. The utilization of ICT in learning in Indonesia has had a long enough history. Initiative hosted the radio broadcast education and educational television is an attempt do the dissemination of information to the education units are scattered throughout the archipelago. This is a manifestation of consciousness to optimize the domestication of technology in helping the learning process of the community. Along with the need for methods and concept learning is more effective and efficient, the utilization of information technology for education was not inevitable. The concept would later be known as e-learning brings the influence of conventional education, to the process of tranformasi in digital form, either generally contents (contents) and his system. This research aims to apply and implement the concept of e-learning is a teaching and learning that enables tersampaikannya learning materials to students using internet media. With the e-learning is expected to facilitate the teaching and learning process is conducted without limited location, time and costs. The method is done by charging a questionnaire to find out the needs of the user that there is a facebook application and utilization in building E-learning applications. The programming is done with the PHP language and customize with FBML is a framework from Facebook itself. Research results is a system application that will be used in assisting the process of teaching and learning online. This application can support distance learning. This application runs in the facebook application that is very easy to be accessed by the user, which the user is a student and lecturer.
Dalam perjalanan operasional data penginderaan jauh di Pustekdata, LAPAN mengoperasikan Bank Data Penginderaan Jauh Nasional (BDPJN) yang gunanya untuk memfasilitasi kebutuhan data penginderaan jauh nasional. Pada tahun 2011, Pustekdata menyusun Master Plan dan Blue Print Teknologi Informasi (TI) BDPJN tahun 2012-2016 dan Master Plan Manajemen BDPJN. BDPJN memiliki target yang tertuang pada Master Plan TI dan Manajemen BDPJN. Diperlukan suatu kajian untuk mengevaluasi apakah kegiatan yang telah dioperasionalkan hingga saat ini sudah menyesuaikan dengan implementasi dari Master Plan yang telah dibangun. Target-target yang tercantum pada Master Plan TI dan Manajemen BDPJN dapat dijadikan parameter untuk mengukur keberhasilan implementasi Master Plan TI dan Manajemen BDPJN yang telah dioperasionalkan hingga saat ini. Metode DeLone dan McLean digunakan untuk mengukur keberhasilan implementasi Master Plan TI dan Manajemen BDPJN. Koefisien korelasi yang dihasilkan dari pengujian menggunakan metode DeLone dan McLean menunjukkan bahwa kepuasan pengguna sangat berpengaruh pada kesuksesan implementasi masterplan BDPJN diikuti dengan meningkatnya kualitas sistem, kualitas layanan, dan kualitas informasi yang juga ikut mempengaruhinya. Selain itu, meningkatnya kepuasan pengguna maka akan berdampak pada manfaat-manfaat yang diberikan oleh sistem BDPJN sehingga dapat membantu meningkatkan dan mempermudah kinerja pegawai.
SPACeMAP is a remote-sensing data portal system owned by LAPAN used to distribute mosaic data of Medium-Resolution to Very-High-Resolution for Provincial Governments. The frequently arising problem is that mosaic images have very large data size, especially for SPOT-6/7 mosaic images. The increasing number of data and users may affect the data loading process on the portal so that mosaic data compression can be considered. SPACeMAP has the Image Compressor feature using the Tile and Line algorithms with a compression ratio (target rate) recommended for optics (15 to 20). This study aims to determine the best algorithm and target rate to get compressed mosaic SPOT-6/7 imagery. The comparison method was done qualitatively through visual comparison and quantitatively by using Compression Ratio (CR), Bit per Pixel (BPP), and Peak Signal to Noise Ratio (PSNR). Results of the experiment show that, quantitatively, both Tile and Line algorithms give a different performance, depends on the zoom level and land cover characteristics. In terms of the qualitative result, the Tile algorithm gives better overall results compare to the Line algorithm. Quantitatively, both algorithms show good performance in the homogenous area. The target rate difference on the testing range does not affect process duration, nevertheless, the Line algorithm has a long process duration compare to the Tile algorithm. However, compression mosaics with lower or higher resolution remote sensing data may provide different results. Hence, this need be addressed on further studies.
Abstract. The demand for remote sensing imagery data has been increasing in recent years in Remote Sensing Technology and Data Center LAPAN, especially the utilization of such data for the maritime field. Data request is recorded increasing trend from 808 scenes in 2015 to become 6773 scenes in 2016. Therefore, Remote Sensing Technology and Data Center should improve its services so that information provided to users could be delivered as fast as possible. The objective of this research was to find the best alternatives dissemination from the current method of data distribution and remote sensing information in terms of speed, scalability, functionality and data maintenance in order to support government program on maritime sectors. Alternative to be examined was based on Web-GIS which means that access to data and remote sensing information could be done online through internet. The used of Web-GIS in this study due to the utilization of the internet already prevalent in the present day. Through this method, users could have obtained data and information from anywhere and anytime. As an example, this paper uses mangrove distribution data in Banten as remote sensing data provided. Results are easily obtained mangrove information; the government can overcome the problems that has emerged as the reduced area of mangrove forest which resulted in causing chain actions such as floods and other disasters. Using Web-GIS can be an effective means of dissemination to speed up service.
