Abstract
Green cover removal is a crucial factor in urbanization scenario. These changes can be clearly observed and estimated by using Geographic Information System (GIS) technologies and satellite images. The Normalized Difference Vegetation Index (NDVI) is a general tool which is used in decision making regarding remote sensing based land cover and land-use related studies. Tasseled cap indices provide more detailed description onseparate land features such as vegetation, water and bare land. Kelaniya is an important city with higher population density and infra-structure development which is very closer to capital city of Sri Lanka. The main objective of this study was to find out the relationship between tasseled cap transformationindices and NDVI.An image from Landsat 8 was used for the analysis while ArcGIS 10.1 was using as the software. From the image analysis process, NDVI and Tasseled cap transformation (TCT) maps were derived for the study area. A strong positive relationship was identified between NDVI andTasseled cap greenness index. Tasseled cap indices enable to provide much more detail interpretations for the judgments made based on NDVI values
