Question

Write one different between the two maps

Answer 1

Answer:In remote sensing, thematic map comparison is often undertaken on a per-pixel basis and based upon measures of classification agreement. Here, the degree of agreement between two thematic maps, and so the difference between the pair, was evaluated through visual and quantitative analyses for two scenarios. Quantitative assessments were based on basic site-specific measures of agreement that are used widely in accuracy assessment (e.g. the overall percentage of pixels with the same class label in each of the two maps and the kappa coefficient of agreement) as well as an information theory based approach that allows the degree of mutual or shared information to be assessed even if different classification schemes have been used to produce the maps. The results indicated that in the first map comparison scenario, focused on labelling, there was a fair degree of correspondence between the maps but with an overall difference in information content of ∼42%. In the second comparison scenario, focused on change in time, considerable change had occurred with a change in class label for ∼42% of the pixels. It was also apparent that global assessments masked local scale changes.

Answer 2

Map 1 and Map 2 represent two different times. Map 1 was made in 1154 CE by al-Idrisi, an Arab geographer. This section is a detail of the Indian subcontinent from his larger map of the world. Map 2 was made by a French cartographer in 1720. Both maps are quite different from each other, even though they represent the same area. In Map 1 we find south India at the place where we would expect to find north India and Sri Lanka is the island at the top. The place names are in Arabic. Some familiar places like Kanauj in Uttar Pradesh have been spelled as Qanauj. In comparison to this Map 2 was made nearly 600 later after Map 1. By that time information about the subcontinent had changed a lot. This map appears to be more familiar to us. The coastal areas, particularly, are more detailed.
