Hitungan Penentuan Awal Bulan Hijriah dan 1 Syawal 1443H

By • • Knowledge, Other, Public • , , • 2 minutes of reading

Salam, bermula awal bulan Muharram 1443H/2021M, negara-negara MABIMS telah menggunakan kriteria yg baru bagi kebolehnampakan hilal (imkanurrukyah) berkaitan dengan penetapan awal bulan Hijriah, iaitu tinggi bulan tidak kurang 3° dan jarak lengkung tidak kurang 6.4°, dan tidak lagi menggunakan nilai-nilai 2° dan 3° atau umur bulan 8jam. Bagi kebolehnampakan anak bulan Syawal tahun ini, ianya agak menarik (sehinggakan telah menimbulkan pelbagai polemik dikalangan masyarakat) disebabkan data falak menunjukkan nilai jarak lengkungnya sangat hampir dengan kriteria minimum. Berdasarkan kiraan falak untuk 1 Mei 2022, iaitu hari ke-29 Ramadan (hari melihat anak bulan Syawal), tinggi bulan di Tg Cincin, Langkawi (stesen rujukan […]

In addressing the effects of plate tectonic motion due to natural disasters such as earthquakes on the coordinates reference system and vertical datum systems for the whole country, JUPEM has successfully established a more accurate, precise and contemporary GDM2020. This newly derived geodetic datum system is fully aligned to ITRF2014, where velocities and PSD are modelled as an intrinsic component of the kinematic/ semi-kinematic concept of the CORS coordinates. In order to facilitate the conversion of various coordinates system in Malaysia, JUPEM has produced numerous sets of datum transformation and map projection parameters to relate the different types of coordinate

Internet of Bodies (IoB)

By • • Knowledge, Other, Public, Research, Teaching • , , • 8 minutes of reading

The term Internet of Bodies conjures up images of humans with cyborg-like features, controlling computers with your mind and syncing up iron man hearts. But you may be surprised to hear that IoB is now not just a science fiction plot.  Almost one billion people worldwide and nearly 70% of the US population are already using IoB. This is the wearable market- smartwatches and fitness trackers. These are all part of the IoB ecosystem, although futuristic inventions that run through your mind may not be that far away either. IoB is revolutionizing healthcare and on its way to improving our day-to-day conveniences, but it

Terms – Geographic(al) Information System, GIScience, Geomatics, Geoinformatics, Geoinformation Technology and Geospatial Technology

Common people, often, get confused with the terms Geographic(al) Information System, GIScience, Geomatics, Geoinformatics, Geoinformation Technology and Geospatial Technology. To understand the differences or similarities among them we need to fine-tune our understanding about these frequently used and interchangeable terms. Geographic Information System (GIS) is a computer-based information system used to digitally represent and analyze the geospatial data or geographic data. The GIS has been called an ‘enabling technology’, because it offers interrelation with the wide variety of disciplines which must deal with geospatial data. Each related field provides some of the techniques which make up a GIS. Many of these related fields emphasize data collection; GIS brings

Spatial vs Geospatial [2]

By • • Knowledge, Public, Research, Teaching • , , • 3 minutes of reading

Mike Goodchild believes that we should make a distinction between spatial and geospatial believing that if spatial is special then geospatial is even more special! The way he sees it is that geospatial is a subset of something much larger that encompases any spatiotemporal frame, any spatial resoultion, non-Cartesian spaces and metrics and so on.  Spatial represents the big picture while geospatial carves out its own area of interest at on on the earth’s surface  He goes on to suggest that any theory of geospatial (geographic information) should be developed quite separetely from a theory of spatial (spatial information) with the proviso

Spatial vs Geospatial [1]

By • • Knowledge, Public, Research, Teaching • , , , , • 2 minutes of reading

Often my students ask about the difference(s) between spatial and geospatial. These two words appear very frequently in remote sensing and GIS literature. The word spatial originated from Latin ‘spatium’, which means space. Spatial means ‘pertaining to space’ or ‘having to do with space, relating to space and the position, size, shape, etc.’ (Oxford Dictionary), which refers to features or phenomena distributed in three-dimensional space (any space, not only the Earth’s surface) and, thus, having physical, measurable dimensions. In GIS, ‘spatial’ is also referred to as ‘based on location on map’. Geographic(al) means ‘pertaining to geography (the study of the

Integrasi Data Geospatial Johor dengan Infrastruktur MyGDI

By • • Knowledge, Other, Project, Public, Research • , , , , , • 4 minutes of reading

Oleh Shahabuddin Amerudin Pengenalan Pembangunan geospatial di Malaysia kini semakin pesat, seiring dengan perkembangan teknologi dan keperluan untuk pengurusan maklumat yang lebih cekap di pelbagai peringkat. Negeri Johor, sebagai salah satu negeri utama di Malaysia, perlu mengambil langkah proaktif dalam mengintegrasikan data geospatial yang dikumpulkan dengan sistem yang telah ditetapkan oleh Pusat Geospatial Negara (PGN). Ini bukan sahaja memastikan data yang dikumpulkan adalah seragam dan boleh diakses oleh pelbagai agensi, tetapi juga membolehkan Johor untuk memanfaatkan infrastruktur yang telah sedia ada, seperti MyGDI (Infrastruktur Data Geospatial Negara), yang dibangunkan oleh PGN. Artikel ini membincangkan bagaimana pelan induk geospatial negeri Johor
