Abstract

This research focused on the application of multi-resolution earth observation satellite data on territory management – case study in Lai Chau province, Vietnam. The objectives of this study were exploring potential of optical satellite images to extract specific information facilitating the nation-al border monitoring operations such as national territory control points, border belt and riverbank errosion surveillance. Comparative analysis were implemented to show advantage of three ground resolution satellite imageries included Landsat8 (30m) – moderate resolution, Sentinel-2 (10m) –high resolution, and Worldview2 (0.5m) – very high resolution.. It was showed that very high ground resolution satellite data benefit for site or position monitoring while moderate and free access satel-lite data such as Sentinel-2, Landsat8 proper for long term change detection at larger scale.
