Detecting Land Use and Land Cover and Land Surface Temperature Change in Lilongwe City, Malawi
Abstract: In south east Africa, Lilongwe city had an observed rapid population growth over the past decade and a half. The same city also had recently observed increased temperatures and adverse weather conditions such as occassional heavy storms which caused severe flooding in January 2017 and December 2017. It was therefore thought wise to do a land use and land cover (LULC) study of the city over time to detect land …

A Novel Feature Level Fusion Method for Classification of Remote Sensing Images
Abstract: Feature level fusion approach is utilized in this paper to classify remote sensing images. Texture features are extracted from panchromatic images using mixed Gabor filter (GB), fast gray level co-occurrence matrix (GLCM) and linear binary pattern (LBP). The resultant texture features are classified using nearest neighbor (k-NN) classification method. Spectral features are extracted from the MS image and segmented using over segmented k-means algorithm with novel initialization (OSKNI). Finally the …

Assessing Urban Land Utilization Using Geographical Information System
Abstract: In all urban centers of the Tigray region, Ethiopia in general, there is inefficient urban land utilization. Inefficient buildable urban land development and management is manifested in the form of vacant, partially utilized and underutilized lands. Most of these lands are exposed to urban sprawl, squatting and land speculation. Moreover, there is inadequate infrastructure provision, under regulation, and shortage of buildable lands; speculation and tenure insecurity are the problems of …

Multi-spectral Data Simulation Method Based on Hyperspectral Data
Abstract: Deep learning algorithms have been widely used in remote sensing image classification and recognition. Due to the difference in parameters such as spectral response functions of different sensors, a single sensor sample dataset cannot meet the needs of other sensors. Constructing sample datasets for different sensors will seriously increase the workload. To solve this problem, this paper proposes a multi-spectral data simulation method based on hyper spectral data and analyzes …
