With the onset of the digital age, printed hardcopy maps have lost their relevance. Instead, the more versatile, digital maps have arrived, which are served through the internet. Suppose you have geospatial datasets to combine and create thematic maps and then serve them through the web. GeoNode may assist you in executing […]

The temporal resolution of the remotely sensed images is improving. Therefore, more attention is sought for the change detection applications. The approach of deep learning is being tried on remote sensing datasets. Here are a few supervised deep learning approaches that are applied for change detection applications using multispectral remote […]
Wetlands are valuable. We need to preserve them. We need to keep a record, an inventory of wetlands, and their inundation maps. Remote sensing can help in this. This article describes a novel way, LiDAR-based mapping.
Dust storms are one of the climatological phenomena. These events are important because they represent a massive amount of erosion and leave a considerable amount of deposition. Dust storms usually transport silt-sized material from the world’s deserts to distant places, thousands of kilometres away. The wind is responsible for lifting […]
Say that you have Sentinel-2 data and want to derive land cover classes from that data. You adopt a common pixel-based classification approach, say, Random Forest. You design a suitable classification scheme and give the training samples to the algorithm. The classification result is straightforward: all the classes are identified […]
Researchers from the UK have used earth observation data to estimate the quality of education in Nigeria. It is novel research altogether, one of its own kind. How spatial information is linked to the quality of education? Researchers have used the information on the adequacy of classroom space as an indicator of […]
The electric vehicle (EV) revolution has begun. Many countries have started electrifying their transportation systems. Probably we are going to witness a historic shift in the transportation history of mankind. Why optimally placed charging stations are getting importance? The acceptance of EVs by the masses, among many other factors, also […]
A few villages at the southern tip of the Indian subcontinent have shown high erosional rates (4 to 10 metres per year). This was revealed in a recent geospatial study conducted using multi-date satellite images. How was it detected? Geospatial technology was utilised for this study. Satellite-based remotely sensed images, repeatedly acquired […]
Agriculture 4.0 is here. The fourth agricultural revolution. It seeks qualitative and quantitative improvements in farm products through technologies such as robotics, the Internet of Things (IoT), big data and artificial intelligence. Precision farming and climate-resilient farming systems have already taken the centre spot. The use of Unmanned Aerial systems […]
