Abstract
The invention discloses a method for analyzing demographic data information by means of satellite images. The method includes the first step of extracting and counting information of all houses of a town or a village through satellite image picture information, the second step of dividing total population publically counted by the town or the village by the number of all the houses of the town or the village to obtain house and population density, the third step of counting the number of all houses in a disaster-affected region through the satellite image picture information, and the fourth step of multiplying the number, obtained in the third step, of all the houses in the disaster-affected region by the house and population density obtained in the second step to obtain the final number of people affected by disasters. According to the method, the problems that current demographic data are generally counted by taking a town or a village as the minimum unit, the disaster-affected region is a village or a group or is even smaller in most cases during disaster-affected evaluation, statistics conducted in the method that population information counted by taking the town or the village as the minimum unit is averaged according to the area and then population information is determined through the disaster-affected region is quite inaccurate and large in error, and disaster evaluation cannot be effectively reflected are solved.
Description
Technical field
The invention belongs to demographic data information analysis techniques, particularly relate to a kind of method utilizing satellite image to analyze population data message.
Background technology
In flood control forecast system, the data analysis of being correlated with will be carried out for Disaster Assessment, wherein being subject to disaster area damage to property and affecting population is one of selective analysis, in vast rural area, the disaster-stricken statistics affecting population is difficult to accurately carry out, to be averaged statistics mainly through disaster area population distribution data, but the general Shi Yizhenhuo township of existing consensus data is that least unit is carried out, when disaster-stricken, often disaster area is that one, village group is even less, at this moment the method for people information carries out that disaster-stricken to affect demographics then very inaccurate to utilize disaster area to determine after the people information added up for least unit with town or township is average by area, error is very large, can not effective Disaster Assessment.
Summary of the invention
The technical problem to be solved in the present invention: a kind of method utilizing satellite image to analyze population data message is provided, with solve the existing people information added up for least unit with town or township average by area after utilize disaster area to determine the method for people information carries out that disaster-stricken to affect demographics then very inaccurate, error is very large, can not the effective problem such as Disaster Assessment.
Technical solution of the present invention:
Utilize satellite image to analyze a method for population data message, it comprises the steps:
Step 1, add up all houseclearings in town or township by the information extraction of satellite image picture;
Step 2, the population of openly adding up with town or township, divided by all houses quantity in town or township, obtain building population's density;
Step 3, by all houses quantity in satellite image picture Information Statistics devastated;
In step 4, the devastated that obtains by step 3, all houses quantity is multiplied by building population's density that step 2 obtains, and obtaining final disaster-strickenly affects number.
Beneficial effect of the present invention:
The present invention utilizes satellite image to add up all houses quantity in township of minimum population unit or town, building population's density is obtained divided by total house quantity by total population, all houses quantity in recycling satellite image statistics devastated, building population's density all houses quantity be multiplied by devastated is utilized to obtain finally disaster-strickenly affecting number quantity, adopt and utilize area average population to add up population suffered from disaster's quantity accurately and reliably than existing in such a way, because house to reflect the size of population, it is high that Billy of the present invention carrys out statistical accuracy by the area size of population, can effectively reflect disaster-strickenly affects number, the invention solves the general Shi Yizhenhuo township of existing consensus data is that least unit is carried out, when disaster-stricken assessment, often disaster area is that one, village group is even less, at this moment the method for people information carries out adding up then very inaccurate to utilize disaster area to determine after the people information added up for least unit with town or township is average by area, error is very large, can not the problem such as effecting reaction Disaster Assessment.
embodiment:
Utilize satellite image to analyze a method for population data message, it comprises the steps:
Step 1, add up all houseclearings in town or township by the information extraction of satellite image picture;
Step 2, the population of openly adding up with town or township, divided by all houses quantity in town or township, obtain building population's density;
Step 3, by all houses quantity in satellite image picture Information Statistics devastated;
In step 4, the devastated that obtains by step 3, all houses quantity is multiplied by building population's density that step 2 obtains, and obtaining final disaster-strickenly affects number.
