Embodiment Construction

[0019] Below by example the present invention is further described:

[0020] 1. With the regional aerial electronic bird's-eye view at different heights as the background, the bird's-eye view can clearly display the regional topography and traffic characteristics. The GIS platform and the electronic bird's-eye view map are spliced ​​together to form a "base map". The graph has all the functions of GIS, that is, single selection, rectangle selection, circle selection, polygon selection, etc. of the target graphics; it has various operations such as table structure, map query, attribute data query, and layer attribute information.

[0021] 2. According to latitude and longitude, mark different types of houses, bridges and other buildings, population, etc. (in villages) in the assessment area on the "base map" according to their latitude and longitude on the GIS platform, and connect each punctuation to the corresponding database. Databases include SQL, ACCESS, ORACLE, etc. The ...

Abstract

Wherein, it relates to a GIS platform, a database, and remote data exchange software. The system can query data, display result, maintains and converts between data and image; it can automatic evaluate loss according to damage sample data, and outputs evaluation report.

Description

Technical field [0001] The invention relates to a method for rapidly assessing earthquake disaster losses based on GIS technology, in particular to a technical scheme for rapidly assessing earthquake disaster losses based on GIS technology. Background technique [0002] Earthquake is one of the serious natural disasters faced by human beings. A destructive earthquake often causes very serious disaster losses and casualties in a very short period of time. In order to deploy post-earthquake disaster relief, it is urgent to understand the disaster losses (mainly direct economic losses such as the destruction of various buildings) and casualties caused by earthquakes. To this end, the earthquake department has formulated regulations on earthquake disaster assessment, which are divided into three forms: rapid assessment, preliminary assessment, and general assessment according to the actual situation, so as to meet the actual needs of governments at all levels for earthquake reli...
