Real-Time Big Data Analytical Architecture for Remote Sensing Application:
Point to remember:
1. What is remote sensing?2. What is big data?3. What is data analytical architecture?4. What is data processing?
Problem statement:
1. Scalability issues, which refer to the application, are likely to be running on large scale.
2. Extraction transformation loading method from low, raw data to well thought-out data up to certain extent;
3. Scalable data management has been a vision for more than three decades and much research has focused on large scale data management in traditional enterprise setting.
4. The run-time system takes care of the details of partitioning the input data, scheduling the program’s execution across a set of machines, handling machine failures, and managing the required inter-machine communication.
5. Difficult to handle & maintain huge amount in remote sensing application.
Proposed architectures:
1. Remote sensing big data acquisition unit.(RSDU)
Description of RSDU:
It collects the raw data from the earth atmosphere and send it to the ground station via downlink channel.
2. Data processing unit (DPU).
Description of RSDU:
The collected raw data information are separated with the help of filtration and load balancing algorithm , useful data for analysis since it only allows useful information, whereas the rest of the data are blocked and are discarded.
3. Data analytics decision unit (DADU).
Description of DADU:
DADU, which is responsible for compilation, storage of the results, and generation of decision based on the results received from DPU.
Proposed algorithms:
1. Filtration and Load Balancing Algorithm.
Description:
This algorithm takes satellite data or product and then filters and divides them into segments and performs load-balancing algorithm.
2. Processing and Calculation Algorithm.
Description:
The processing algorithm computes the results for dissimilar restrictions against each incoming block and sends them to the next level.
3. Aggregation and Compilation Algorithm.
Description:
It collects the results from each processing servers against each and then combines, organizes, and stores these results in RDBMS database.
4. Decision-making algorithm.
Description:
The algorithm varies from requirement to requirement and depends on the analysis needs.
