The present article reports the results of an extensive empirical evaluation of spatial resolution of a digital large format Intergraph DMC sensor. The parameters of the study were flight direction, ground sample distance (GSD) and the distance from the image center. The key finding of the study was that the resolution of the DMC panchromatic large-format image was clearly dependent on the dist...

In this paper, we propose a pixel level image fusion algorithm for merging Landsat thematic mapper (TM) images and SPOT panchromatic images. The two source images are first decomposed using the discrete wavelet frame transform (DWFT), which is both aliasing free and translation invariant. Wavelet coefficients from TM’s approximation subband and SPOT’s detail subbands are then combined together,...

In remote-sensing image processing, fusion (pan-sharpening) is a process of merging high-resolution panchromatic and lower resolution multispectral (MS) imagery to create a single high-resolution color image. Many methods exist to produce data fusion results with the best possible spatial and spectral characteristics, and a number have been commercially implemented. However, the pan-sharpening ...

Updating cadastral information is crucial for recording land ownership and property division changes in a timely fashioned manner. In most cases, the existing cadastral maps do not provide up-to-date information on land parcel boundaries. Such a situation demands that all the cadastral data and parcel boundaries information in these maps to be updated in a timely fashion. The existing technique...

Pansharpening aims at fusing the rich spectral information of multispectral (MS) images and spatial details panchromatic (PAN) to generate a fused image with both high resolutions. In general, existing pansharpening methods suffer from problems distortion lack detail information, which might prevent accuracy computation for ground object identification. To alleviate these problems, we propose H...
