Cadastral Application of Satellite Images with High Spatial Resolution in Easter Island (chile)

The purpose of this project is to demonstrate the potentiality of satellite images with high spatial resolution (QuickBridII) and GPS system for cadastral applications in a zone so particular in landuse administration like Rapa Nui or Easter Island, located in the middle of the Pacific Ocean, lat 27o 07’ long 109o 22’ in front to the Chilean coast. Additionally, the last cartographic information, made with GPS measurements, was indispensable in the actualization and study of important changes in different points of the island, providing precise measurements in georeference for the landuse map of the city and geometric control point to the correction processing of the satellite image. Created this cartographic data base support in the satellite image processing we can mixed this information with the cartographic mosaic, all this to know the reality of the state`s properties and its future transference to the ancient owners of the island. However, the potential of this work was the way to study the landuse changes in Rapa Nui, using satellite tools and new techniques in the island to improve the urban growing planning and so he conditions of people’s life, but knowing too its impact according with that urban planning and considering the course of historical errors about this topic. So this project gives an actual situation in the cadastral files used in the island associated with a cartographic data base for the Ministry in charge, being very important to show the application in urban planning using geomatics technologies, in relation too with to choose the best alternative to be used in this particular area, showing an atypical situation for its different culture in reference to belong and landuse possession, specifically; and in other aspect, this job pretend to get a good level of security in order to future inversions in urban infrastructure and improvement of quality life in the moai`s (megalithic sculpture) land.
