摘要：

This paper shows some results focused on topographic 3D surveys and volumetric temporal changes analysis on tidal marshes and coastal dunes systems. The topographic data (x,y,z) were colected by softcopy photogrammetry and airbone lidar sensors and were analysed and integrated using the GIS capabilities for spatial analysis' The results show the advantages of these near-synoptic sources of data (with high spatial and temporal resolution) when applying to fast evolving coastal features (beaches, dunes....). The spatial and temporal topographic internal variability of these coastal systems at detailed scale, on the other hand, give to these technologies an important role within the context of future coastal geomorphology research. The spatial capabilities provided by GIS (natural risk assessment, DEM, modelling, sedimentary butgets,...) appears as the natural context for integration, analysis, visualization and modelling of these georeferenced data.
