As the name suggests, “remote sensing” refers to capturing and monitoring information from the longest distance in wireless mode. For instance: sensing the green vegetation on the earth’s surface from a satellite. For that, it uses electromagnetic waves obtained from sensed objects in the form of diffraction, emission, and reflection.This article is envisioned to provide key Remote Sensing Project Topics along with its research areas, trends, issues, and techniques!!!

 From this, we can identify the need and importance of enhancing natural resource management and a green environment.  Further, the remote sensing systems or platforms provide below data,

What are the important issues in remote sensing?

• Inabilities of Remote Sensors
  • Some sensors are lacking in measuring the events in uncertain situations
  • Although the inferential techniques are utilized, the sensed data may be inaccurate
  • For instance; underwater research
• Insufficient Non-commercial Remote Sensing Data
  • Although there are several advanced remote sensing tools, lack of data distribution availability may cause a severe impact in the remote sensing field
  • Even the data is commercially available, it is very expensive for economically weak researchers
• Absence of National Spatial Data Infrastructures (SDI)
  • Specifically, developing countries are largely get affected by this issue
  • Since it stops the remote sensing data accessibility for processing and assessment

For illustration, here we have taken the sensor as an example from the above list. Generally, there are numerous sensors are available for the remote sensing process. And, these sensors are differentiated by their characteristics, merits, and demerits. Depending on this information, one should select the appropriate sensor for their project.

Suppose if the sensor attempts to capture images then it should need to consider certain factors such as area coverage, image resolution, flight restriction, etc. For instance: the satellite has a global view, the drone has small and the aircraft has a limited view. Here, we have given you a few most widely used sensor technologies for remote sensing.

What are the 3 remote sensing tools in geography?

• Sound Navigation Ranging (Sonar)
• Sensors, Radiometers and Spectrometers

From the above, Sonar and LiDAR are used to construct the topographic models. Although these techniques are used for a common purpose, it has one main difference i.e., a supportive environment. In specific, Sonar can be used underwater and LiDAR can be used underground. In addition to topographic models, we can also construct assessment models. Examples of topographic models are delineating watersheds, archaeological sites, and flood risk prediction.

What is the classification of remote sensing data?

Now, we can see the importance of “classification’ in remote sensing. Classification is one of the main processes in digital image processing. While classifying remotely sensed images, it assigns pixel/pixels to the land cover class. If the pixel is bound up with one class, then it is referred to as hard or crisp classification. If the pixel is bound up with multiple classes, then it is referred to as soft or fuzzy classification.

Before implementing the classification process, pre-process method has to be implemented. Since it is necessary to eliminate the artifacts for processing only meaningful information. Here, we have given you a list of preprocessing methods based on artifact types.

• Haze and Low illumination (Histogram Truncation)
• Contextual noise (Difference of Offset Gaussian Filters)
• Speckle noise (Dynamic Thresholding and Image Rationing)
• Contrast Variation (Sub-histogram Equalization and Fuzzy Clustering)
• Blur (Improved S2CVA and Gram-Schmidt Spectral Sharpening)
• Brightness Distortion (Cuckoo Search-based Discrete Wavelet Transform)
• Intensity Variation (Simulated Annealing, Hybrid Ant Colony and Genetic Algorithm)
• Haze (Radiative Transfer-based Detail-Injection Method)
• Irregular Intensity (Alternating Direction Method of Multipliers with Split Bregman Iteration (ADMM-SBI) and Maximum-a-Posterior)
• Brightness and Contrast (BAT algorithm for Histogram Equalized Contrast Enhancement)

            Now, we can see the classification process in detail. The input of the classification process is preprocessed data. Generally, the classification is categorized into two types where one is pixel-based classification and the other is object-oriented classification. In pixel-based classification, the whole scene is processed pixel-by-pixel. So, it is also addressed as per-pixel classification. Object-oriented classification, the whole scene is decomposed into several segments/patches using the image segmentation technique. Further, it is used as high-spatial-resolution imagery where the characteristics are subjected to the conventional fuzzy logic.

Deep Learning (DL) is the most widely used technique for performing supervised learning processes as classification. These supervised classification algorithms are used to allocate unknown pixels in the place of m possible classes. Further, the selection of a particular classifier is based on the input data characteristics. Parametric classification assumes that observed vectors in each class and the spectral band are classified as Gaussian. Nonparametric classification will make such an assumption. For your information, here we have classified some extensively used algorithms.

• Hyperspectral Classification
  • Matched Filtering
  • Linear Spectral Unmixing
  • Spectral Angle Mapper
  • Spectral Feature Filtering
  • Binary Encoding
• Nonparametric Classification
  • Parallepieped
  • Neural Network
  • 1Dimensional Density Slicing
  • Expert System Analysis
  • Nearest-neighbor
  • Minimum Distance
• Parametric Classification
  • Maximum Likelihood

Further, other primary challenges need to be addressed such as environmental state, system trade-off, high-altitude imaging, etc. Since all these challenges may cause an effect on observation quality. Deep learning plays a major role in tackling many important research challenges. Besides, we also support you with other efficient techniques to solve any sort of complicated research issue. 

Deep Learning Methods for Remote Sensing

The measurement uncertainties like varieties, complexity, and volume create blockages in the data analysis process. To crack this main obstacle, machine learning was employed. These techniques automate the analysis process and enhance the observation quality. In this, it first removes the unwanted artifacts using deep learning which is a subset of machine learning.

The motive of deep learning techniques is to consider the important factors such as pan-sharping, denoising, fusion, single / multi-band super-resolution, restoration, etc. to enhance the Remote sensing and GIS observation.

Performance Evaluation in Remote Sensing

Although remote-sensing-driven data are evolving fast, it has some in-built errors from different sources. To reduce the errors, we need the source and perform an accuracy evaluation. For that, first, develop metadata before strategy decision and analysis. And also, it needs GIS layers to support classification. For any kind of application, we use appropriate performance metrics to enhance the efficiency of the system.
