Machine Learning in GIS procures the growing needs for the collection, processing, management, and efficient use of reliable spatial information. This growing demand is caused due to businesses, governments, and researchers working on making more sophisticated developments to ease human-to-human communication, commutation, and urbanization. The best example for better understanding this growth is the use of spatial data to visualize the current location to predict events and enhance service delivery. As governments and businesses across the globe are working on how to tackle the escalating social, economic, and environmental challenges to offer more scalable solutions to people. Machine learning has been a vital solution -How?
Geospatial information systems perform tasks related to collecting, managing, manipulating, analyzing, and visualizing spatial data as a system. This data set usually consists of satellite images, which are the observatory information about latitudes, longitudes, areas, perimeters, centroids, lengths, etc. Unlike any tabular data, spatial data is hard to compute due to the availability of spatial attributes for each observation. The velocity, variety, and types of spatial data for analysis or geometric manipulation to perform techniques like clip, erase, buffer, union, and interpolation, can be optimized using machine learning techniques.
Machine Learning, a part of AI, allows computers to perform tasks that typically require human monitoring, intervention, or intelligence to make decisions. Machine Learning helps computers to read data-driven algorithms to learn from data and deliver the answers that one required for identifying a solution or sometimes delivering a solution directly to a complex challenge. Applying machine learning for spatial data analysis is opening up more massive opportunities than ever before. Machine Learning models that match or even surpass human accuracy at performing tasks such as image recognition, image identification, semantic segmentation, reading comprehension, translating text to speech, etc., can evolve geographic information systems to study, analyze and understand spatial data.
How Machine Learning is Used in GIS?
Using machine learning tasks such as regression, classification, and clustering for spatial data can ease the time consumed with performing critical spatial data analysis techniques like interpolating and Union. Especially, applying Machine learning algorithms like linear regression, tree-based regression, or support vector machine regression to predict target variables to check the relevancy of having more similar values can help in performing better analysis.
Similarly, the machine learning classification algorithms like maximum likelihood, support vector machine, and decision tree can be leveraged for spatial classification. Particularly for classifying the land cover class from satellite images. Another machine learning advantage for spatial data analysis is clustering. The clustering technique applies the same meaning as conventional machine learning for spatially constrained data clustering. We can group a large number of observations into a few clusters according to the pattern similarity between those variables.
The use of Deep Learning
Deep learning closely resembles the architecture and work functioning of the human brain, which provides it the ability to make decisions based on past knowledge. Deep learning can be attributed to three primary developments in GIS advancement including data, computing, and algorithmic improvements. One of the important uses of deep learning is digital mapping. The deep learning models can seamlessly work with satellite images on large geographic areas and arrive at a map containing all the roads for the region, to help with solutions like driving navigations, location information sharing, the digital blueprint of towns, etc. Apart from digital maps, deep learning can be taken a step further to advance computer vision models with this information collected, analyzed, and predicted.
Applying Computer Vision to Geospatial Analysis
Computer vision is a dream technology for everyone looking forward to being more productive when it is impossible to analyze and derive insights through traditional applications. Computer vision tasks and applications that can be applied to GIS range from Image classification, object detection, semantic segmentation, instance segmentation, and more.
1. Image Classification
Image classification for geospatial data analysis can be leveraged to categorize geotagged photos, videos, QR codes, etc. which based on location, time, and activities can help governments and businesses in making better decisions. For instance, a business can seek opportunities to run billboards advertising based on the location, time, and activities of people in a particular location.
2. Object Detection
With object detection practice, the computer can identify objects within an image as well as their location based on geotagging. This can be a very important task for GIS—finding what information resides in satellite, aerial, or drone imagery, locating it, and plotting it on a map. This can be further used for infrastructure mapping, anomaly detection, and feature extraction.
3. Semantic Segmentation
Semantic segmentation allows machines to classify each pixel of an image and identify if it belongs to a particular class. Within GIS data, semantic segmentation can be leveraged for land-cover classification or to extract transportation networks from satellite imagery.
4. Instance Segmentation
Instance segmentation is another type of image segmentation task related to computer vision that allows for more precise object detection. During this segmentation, after identifying every object, a precise boundary for each object is marked out. Which can be used to improve the user experience while understanding digital maps.
Applying Machine Learning in GIS
Geographic information systems are powerful tools for effective decision-making for any business or industry. As it allows the analysis of environmental, demographic, and typographic information. Machine learning compiled with GIS applications allows businesses to consumers to make real-time informed decisions that are beneficial. Here are a few use cases that define how machine learning can scale GIS data is experiencing increased outcomes.
1. Digital Mapping: GIS can be used to provide a visual interpretation of data. Google Maps is an excellent example of a web-based GIS mapping solution that people use for everyday navigation purposes. However, smart mapping technology powered by machine learning has significantly advanced and is used by governments and various industries to take an in-depth look at natural resources, availability of electricity, and water supplies, more.
