Penginderaan Jauh Sistem Satelit

Sebagai Teknologi Informasi Penyedia

Data Spatial Wilayah Pesisir dan Laut

Penginderaan Jauh Sistem Satelit

Remote Sensing (Penginderaan Jauh):

is the science of collecting information

about ground features without being in

physical contact.

(SPOT Asia, 2003).

Remote Sensing Definition

The science, technology and art of obtaining information about an object, area or phenomenon through the analysis of data acquired by a sensor which is located at a distance from the object, area or phenomenon

(Lillesand and Kiefer, 1994)

Sumberdaya Pesisir dan Laut

Indonesia memiliki wilayah pesisir dan laut yang luas, serta pulau-pulau kecil yang berjumlah ribuan.

Sumberdaya pesisir dan laut melimpah

Diperlukan data/informasi spasial untuk pemetaan dan monitoring guna pengelolaan dan pelestarian sumberdaya tersebut.

Penginderaan Jauh Satelit Sebagai Teknologi Penyedia Data/

Informasi Spasial

Kelebihan Penggunaan Teknologi ini adalah:

- Informasi yang diperoleh mutakhir (terbaru)

- Data/informasi yang diperoleh Akurat

- Cepat dalam perolehan data dan informasi

- Mudah

- Low cost (biaya rendah dibandingkan metode survei)

- Efektif dalam penggunaan

- Konsisten dalam peyediaan data

- Tenaga operasional yang diperlukan sedikit

Investasi di awal besar

Tenaga terampil relatif terbatas

Kendala liputan awan pada daerah tropis (khususnya pada sensor pasif)

Keterbatasan Penggunaan Teknologi Satelit Sebagai penyedia Data/Informasi Spatial Adalah:

8

Data/Informasi Spasial yang Dapat Diperoleh Dari Teknologi ini untuk Sumberdaya Pesisir dan Laut Adalah:

Pulau-pulau kecil

Terumbu karang

Padang lamun

Mangrove

Perikanan

Hutan pantai

Fitoplankton

dll

Gelombang

Arus laut

Stereo Collection Scenario

Collection Capability

The satellite circles the globe 14 times per day, or

once every 98 minutes

Designed to take digital images of earth from 400 miles (680

kilometers) up and moving at a speed of about four and a half

miles (seven kilometer) per second

the satellite camera can distinguish objects on earths surface as small as one meter square, about three feet, in size.

This is significantly more detail then has ever been available in

commercial satellite imagery before.
