For mapping the #urban_areas growth we can use both pixel based and #object_based methods to classifying. personally, in this case I would rather to say eCognition is more useful because it’s making decisions is based on objects that carefully classify the features according to their patterns. it can easily make the groups of buildings, roads, parks, and other land-use classifications just by merging the same and related pixels in the unit object. since, the urban features follows relatively similar patterns, the #OBIA (Object-Based Image Analysis) is more efficient which be supported by various software, But #eCognition provides even #Fuzzy_OBIA and #Deep_Learning tools to make the decisions…

As melhores ferramentas de software são aquelas em que o analista/desenvolvedor tem mais experiência de uso. No que diz respeito à verificação do crescimento urbano, o mais importante é ter acesso a bases de dados atualizadas, principalmente imagens de satélite e dados públicos sobre urbanidades. Utilizando ferramentas como o QGIS, por exemplo, é possível criar modelos para a interpretação desses dados com algum nível de automação. Com técnicas de programação, é possível monitorar o crescimento urbano em vários aspectos.

A detecção de mudanças como uma tecnologia de monitoramento automatizada pela IA permite aos tomadores de decisão terem em mãos informações das áreas de crescimento das cidades e com isso cruzar camadas de informações como modelos de terreno, dados demográficos, áreas de suscetibilidade e de risco, possibilitando entender que como a cidade cresce e para onde, podendo impedir a tempo a ocupação ilegal em áreas de risco, áreas de preservação dentre outros. Isso no futuro pode ser importante, pois, diminui-se o impacto de perdas humanas em caso de desastres naturais.

Change detection in remote sensing compares multi-temporal imagery to identify differences in land cover over time. It involves preprocessing images, such as registration and normalization, followed by pixel-based or object-based analysis to detect changes. Common methods include image differencing, vegetation indices, and machine learning algorithms. Change detection is crucial for monitoring urban growth, deforestation, and environmental degradation, aiding in decision-making for sustainable development.
