River fluctuation analysis system and method employing aerial photograph and GIS (Graphical Information System)

Abstract

The invention provides river fluctuation analysis system and method employing aerial photograph and a GIS, which can carry out the mobile comparison of low-water channels easily. The invention comprises an aerial photograph receiving part and a digital map receiving part which are connected with a system driver component and used for receiving aerial photographs and digital maps; an interface part which is used for the data interface between the key input of a user and the system driver component and a CPU (Central Processing Unit) and an RAM (Random Access Memory); a display part which outputs the aerial photographs and the digital maps into images, and outputs the analysis result into images; a database which consists of river plane figure DB and river attribute information DB. The system driver component transforms the resolution and capacity of each data according to received aerial photographs and digital maps, so as to provide coordinate systems to the aerial photographes, separate river regions in each aerial photograph of the area into a plurality of regions, analyze river changes and relize control in the way of driving warning when identifying changing ranges.

Description

technical field [0001] The present invention relates to a river plane change analysis system and method using aerial photos and GIS, more specifically, the present invention relates to the following river plane change analysis system and method using aerial photos and GIS, wherein, by By setting actual coordinate values ​​in annual aerial photographs of target rivers and automatically comparing photographs of low waterways and embankments on an annual basis, quick decision-making data can be obtained. Background technique [0002] As is well known, river maintenance and river course maintenance currently being carried out are carried out collectively while ignoring the characteristics of the flow of the river. As a result, the artificial treatment of rivers is still going on until now. Therefore, although it has a profound impact on the physics, chemistry, and biology of rivers and river courses, the actual situation is that the causes of human-made river disturbances and th...

Problems solved by technology

[0003] However, until now, it is clear that there is no analytical method technology at all in the system for analyzing the changing appearance of rivers. Therefore, it takes a very long time for the government office to make decisions on river maintenance and river planning, and the grounds for this are inaccurate. , such that the problem of having decision-making behavior proceed hastily
