Erdas Imagine Satellite Image Layer Mosaic or Layer Stitch

Erdas Imagine Satellite Image Layer Mosaic or Layer Stitch

This tutorial demonstrates how to mosaic two adjacent satellite images to create single satellite image using ERDAS IMAGINE MosaicPro. When study area is large and satellite images collected along the same or adjacent satellite paths to cover the entire area, Image Mosaicing is required to seamlessly joining or stitching these images to generate a new raster dataset.

Erdas Imagine NDBI (Built up) using Model Maker or Spatial Modeller for Landsat 8

Erdas Imagine NDBI (Built up) using Model Maker or Spatial Modeller for Landsat 8

This tutorial demonstrates how to calculate NDBI using ERDAS Imagine Model Maker or Spatial Modeller. The Normalized Difference Built upIndex (NDBI) is an index of built up or urban areas where there is typically a higher reflectance in the shortwave-infrared (SWIR) region, compared to the near-infrared (NIR) region. NDBI = (SWIR – NIR) / (SWIR + NIR ) NDBI values ...
