Abstract
High resolution satellite images are rich source of geospatial information. Nowadays, these images contain finest spectral and spatial information of ground realities in different electromagnetic spectrum. Many image processing softwares, algorithms and techniques are available to extract such information from these images. Multi spectral as well as panchromatic (PAN) high resolution satellite images are missing, one important information, regarding ground features and realities that information is attribute information which is not directly available in high resolution satellite images. From very first day, this information used to be collected through indirect ways using GPS, digitizing, geo-coding, geo tagging, field survey and many other techniques. Our real world has vertical labels for ground observer to identify and use this information. These vertical labels are present in form of names, logos, icons, symbols and numbers. These vertical labels ease us to work in real world. Satellites are unable to read these labels due to their vertical orientation. Making satellite/aerial imagery rich of attribute information, we have the possibility to design our world accordingly. Just like vertical labels we can also place real physical horizontal label for space sensors, to make this information directly available in high resolution satellite/aerial imagery. This work is about possibilities of such techniques and methods.
Highlights
Panchromatic (PAN) satellite imagery has been used successfully in different applications such as topographic mapping and terrain modelling
Once I was part of data collector team for a company, they utilized the high resolution satellite images to collect the vertical labels, most the work, days, and people are doing the same thing for data collection
We leave the natural places as an exceptions, because they carry their own information in satellite images at some extent, the rest of extent is not hard to find out.in some cases as airports, bus stations, train stations, fuel stations, places of worships e.g. mosques, they carry their real cartographic signs and are identifiable in high resolution satellite images
Summary
Panchromatic (PAN) satellite imagery has been used successfully in different applications such as topographic mapping and terrain modelling. N. Fareed ful quality; these images contain very high spatial detail. Fareed ful quality; these images contain very high spatial detail Spatial resolution of these images is increasing rapidly with time. Manmade structures are defining the new horizon, while natural disaster vanishing the old ones. Such changes cannot be accommodated without help of high resolution satellite images. People use high resolution satellite images in form of printed sheets to collect the attribute information of manmade structures. Remote sensing and satellite imagery are new things in modern world. The science of high resolution satellite imagery is demanding new horizons as well as new directions to work
