Change Detection for Topographic Mapping Using Three- Dimensional Data Structures
Identifying significant changes to our urban areas is a prerequisite for accurate topographic mapping. This paper presents an approach based on octree data structures to identify change between two sets of point cloud data. The aim of the study was to establish if a method based on the comparison of point clouds could be used to detect simply where topographic change had occurred. As many of th...
متن کاملData Fusion for Topographic Object Classification
This paper presents research conducted into the automatic recognition of features and objects on topographic maps (for example, buildings, roads, land parcels etc.) using a selection of shape description methods developed mostly in the field of computer vision. In particular the work here focuses on the proposal and evaluation of fusion techniques (at the decision level of representation) for t...
متن کاملComparing Three Regression Models for Reconstructing Groundwater Level Data (A Case Study)
The base for hydrology studies is accurate data. However, the gaps and shortage of sufficient data exist n the most hydrology data such as underground water data as the most important and cheapest water source, lack of data take places due to various reasons such as Inability to measure and faille to register statistics. Missing data or incorrect statistics, Therefore, estimating the missin...
متن کاملChange Detection for Update of Topographic Databases through Multi-level Region-based Classification of Vhr Optical and Sar Data
The geographic database producers need improved and faster updating methods for their topographic databases to fulfil the user’s demand. In this context, change detection methods using remotely sensed data are interesting tools applicable on wide areas and are less demanding for human work. Indeed, database update is currently mainly realized through a tedious and laborious photogrammetric rest...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
