Contribution of Remote Sensing in Mapping Industry According to Wikipedia remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on Earth. It is including both on the surface, and in the atmosphere and oceans. The way its detect and classify is by propagated signals such as electromagnetic radiation emitted from aircraft or satellites.
The era of globalization, remote sensing has enabled mapping, studying, monitoring and management of various resources like agriculture, forestry, geology, water, ocean and so on. It has more enabled monitoring of environment and in that way helping in conservation. Previously, it has grown as a major tool for collecting information on almost every aspect on the earth. With the availability of very high spatial resolution satellites in the recent years, the applications have multiplied.
In Malaysia remote sensing has been used for various applications during long time and has contributed significantly towards development. It is also give contribute into Malaysia mapping industry. Navigation Satellites and Earth Observation Satellites are two of the most widely used satellites in Malaysia. Since the introduction of Malaysian Active GPS System (MASS) by Department of Survey and Mapping Malaysia (DSMM) and the establishment of Malaysian Remote Sensing Agency in 1988, the application from both of this technology has increased greatly.
The government sectors are heavily using the technology to plan and assess land development, disaster management and to manage security issues. Meanwhile in the private sector, the applications are widely used to provide services in the geospatial industries. In the middle 2008, ANGKASA with the collaboration of SIRIM Berhad conducted a study investigating the space industry segment in Malaysia.
The study includes the GNSS and remote sensing industry which is vital part of the downstream space related industry in Malaysia. The study also includes a workshop entitled Downstream Space Application Industry. This study gathers a lot of information from key local industries, universities and government agencies to share knowledge, experience and technology updates in Global Navigation Satellite System (GNSS), Remote Sensing and Satellite Communication.
This paper reports the current status of Malaysia’s GNSS and Remote Sensing downstream application, before the economic downturn and issues to be resolved to map the future space-based industry development plan. The reason why this collaboration was conducted, it is because nowadays the use of remote sensing is very reasonable. For example, high resolution satellite data have real potential for the mapping of the physiognomy of tropical vegetation. Differentiation of the groups of species was not possible.
The cartographical units retained correspond to a physiognomic typology produced by classification of woody formation according to cover density. The spectral response of a plant formation varies in relation to the position of this formation in the toposequence. Therefore, in order to obtain reliable mapping, it is necessary to use other information than the satellite data, such as the terrain, to stratify the land into similar sections within which relations between objects and images are constant.
