The thematic maps asked.
Specifically, step S1 obtains social media data from computer network, and obtains the calamity in social media data
Evil emergency information.
When the disasters such as earthquake occur, the network user can be issued by social medias such as microblogging, mhkc, wechats and be based on position
The information of the natural calamities such as the earthquake of service.Largely propagated by the network media about disaster information.This category information has
The features such as details is abundant, procurement cost is low, renewal speed is very fast.There is the information of a large amount of the condition of a disasters with this kind of embodying information, can be ground
The calamity emergencies such as shake provide additional effective information, the subsidiary discriminant for helping to screen to image are polymerize with remote sensing image, if very
Good be used can effectively shorten rescue time.
After earthquake disaster generation, it can be crawled in certain period of time about the earthquake from internet by crawlers
The information of disaster, and the earthquake disaster emergency information is obtained from the information all about the earthquake disaster.
Calamity emergency information refers to the related information of meeting an urgent need with disaster.
For example, the impaired information in the injures and deaths information of personnel, the trapped information of personnel, house, the information of medical material, rescue
The information etc. of strength, belongs to calamity emergency information.
According to the content of calamity emergency information, calamity emergency information can be divided into different types.Calamity emergency is believed
The type of breath may include：Lifeline engineering class, earthquake situations the condition of a disaster class, medical epidemic prevention class, rescue and relief work class, is sought at secondary disaster class
Class etc. is helped in emergency, but not limited to this.
Such as：" 5 people's conditions of the injury of the villages D of the counties C of the cities B of A provinces are heavier, need to give treatment in time ", which belongs to, seeks to rescue class calamity emergency information；
Belong to earthquake situations the condition of a disaster class calamity emergency " between collapsed house 10 " in " between the cities B of the A provinces areas the C streets D collapsed house 10,40 is homeless "
Information, " 40 is homeless ", which belong to, to be sought to rescue class calamity emergency information.
It can be subdivided into several subclasses per class calamity emergency information.
For example, seeking to rescue class can be divided into that injures and deaths are sought help, the victims of the disaster are stranded, seek the subclasses such as placement, epidemic prevention demand.
Therefore, after obtaining calamity emergency information, you can determine calamity emergency information according to the content of calamity emergency information
Type.
When user is released news by the social media in the terminals such as mobile phone, since the terminals such as mobile phone are with positioning such as GPS
Module, social media have the function of that geo-location service, the information of social media publication can carry geography information.This type of information category
In spontaneous geography information.
(Volunteered Geographic Information, abridge spontaneous geography information VGI, also referred to as volunteer
Geography information), refer to user by way of cooperating online, with common handhold GPS terminal, the high-definition remote sensing of Open Access Journals
It is referred to based on image and the geographical knowledge of personal space cognition, the geography information create, edit, managing, safeguarding.Spontaneously
The concept for managing information was proposed by M.F.Goodchild in 2007.M.F.Goodchild points out traditional unidirectional geography information clothes
Business pattern will gradually change to interactive Cooperative Mode, and user is both the user of geography information, while be also supplier.
After obtaining earthquake disaster emergency information, the atural object in each earthquake disaster emergency information is extracted.
Atural object (culture) is to refer to various corporeal things (such as mountains and rivers, forest, building) and intangibles on ground
The general name on (Ru Sheng, circle of county etc.).Refer to relatively-stationary object on earth surface.
For example, the information of user's publication is " 36 personnel of H factories of the counties G of the cities F of E provinces are stranded ", atural object therein is H factories.
Due to atural object at the earth's surface on be relatively fixed, what geographical location was to determine, described in administrative area be also true
Fixed.Therefore, the title of atural object, shape classification, geographic coordinate information, institute can be preserved in the place name look-up table pre-established
The every grade of administrative area belonged to.
After extracting atural object in earthquake disaster emergency information, according to the name query place name look-up table of atural object, the ground is obtained
The shape classification of object, geographic coordinate information, affiliated every grade administrative area.
According to remote sensing physical modeling, all parameter groups can be needed to be traversed for by the range of input parameter, the calculating of model
Conjunction obtains under each parameter combination as a result, simultaneously expressing in table form.Suitable parameter is found based on cost function
Process is the refutation process of Remote Sensing Model.
The latitude and longitude information of different regions step by step is contained in the place name look-up table of foundation, is had by the title of atural object
The retrieval of restriction, return is a data, consistent with the place name of retrieval and include latitude and longitude coordinates.
Place name look-up table can first pass through the foundation of the tool in GIS platform in advance.For example, by ArcGIS
ArcCatalog establishes place name look-up table.
It include geographic coordinate information in place name look-up table.Due under different earth coordinates, the geography of same atural object
Coordinate has differences, and therefore, establishes place name look-up table and needs to use an existing earth coordinates.
Earth coordinates are the coordinate systems that face is set up on the basis of reference ellipsoid in geodesic survey.The position of ground point
It sets and is indicated with geodetic longitude, geodetic latitude and geodetic altitude.The establishment of earth coordinates include selection one ellipsoid, to ellipsoid into
Row positioning and determining the earth known date.
The earth ellipsoid that one shape, size and positioning, orientation are determined is reference ellipsoid.Reference ellipsoid is once true
It is fixed, then indicate that earth coordinates have built up.
Common earth coordinates include three types：Referenced-centric system, geocentric coordinate system and Local Independent Coordinate System.I
The common earth coordinates of state include：WGS-84 coordinate systems, Beijing Geodetic Coordinate System 1954, Xi'an Geodetic Coordinate System 1980 and new 1954 Beijing
Coordinate system.
Preferably, the place name look-up table in the embodiment of the present invention is established under WGS-84 coordinate systems.
WGS-84 coordinate systems, referred to as World Geodesic Coordinate System 1984 are united, and are the unified geocentric coordinate systems in a whole world.
Place name look-up table is multistage place name look-up table.
For example, be the second level using provincial administrative area as the first order, local administrative area, administrative areas at the county level are the third level, until
Minimum administrative area.Usually, the minimum administrative area in city is street, and the minimum administrative area in rural area is village.
In place name look-up table, the relevant information of whole atural objects in the administrative area can be preserved under minimum administrative area.
Since atural object shows as certain flat shape in plane map, the shape of atural object is generally abstracted as three kinds of shapes
Classification：Punctual geo-objects, linear ground object and area feature.
With the variation of remote sensing image spatial resolution, it is variable that identical atural object, which shows flat shape,.Establish place name
, can be using the shape classification under a specific spatial resolution as the shape classification of atural object when look-up table, it can also be right in advance
The shape classification of atural object provided, but not limited to this.
For different shape classifications, the geographic coordinate information of the atural object preserved in place name look-up table is different.
When the shape classification of atural object is punctual geo-objects, the geographic coordinate information of the atural object is the warp of the point where the atural object
Latitude；
When the shape classification of atural object is linear ground object, the geographic coordinate information of the atural object includes the line segment where the atural object
On several points longitude and latitude；Several points include two endpoints of line segment, and are spaced in line segment with preset longitude and latitude
The point of upper selection；
When the shape classification of atural object is area feature, the geographic coordinate information of the atural object is the external square of minimum of the atural object
The longitude and latitude at the center of shape and four vertex.
For example, provincial highway is linear ground object, the extension of this road is longer, passes through multiple areas, can combine the condition of a disaster spot
Area identifies the effective links in provincial highway, and obtaining the provincial highway by inquiry place name look-up table is located at disaster area minimum administrative area Nei Lu
The geographic coordinate information of section.
Preferably for linear ground object, it is divided between preset longitude and latitude 0.05 second.
Known terrestrial equator radius is about 6378.2 kilometers of (sources：Baidupedia), circumference calculation formula：S=2 π R,
Wherein, S indicates equatorial perimeter, and R is equatorial radius, and π is pi；It enables pi be approximately equal to 3.14, then calculates equatorial perimeter about
It is 40055.096 kilometers.Known circle is 360 degree, 1 degree of 60 points of correspondence, 1 point of 60 meters of correspondence, then every point of corresponding spatial variations range
About 30.9 meters, about the spatial resolution size of one pixel of LandSat images；Equator longitude changes 0.05 second range about
It is about 1.5-2 meters corresponding, it is corresponding with the spatial resolution size of one pixel of high spatial resolution image.Therefore, therefore it is preset
Longitude and latitude interval can accordingly be adjusted based on the spatial resolution size of the corresponding remote sensing image pixel used.
For area feature, can preserve successively the minimum enclosed rectangle of the atural object counterclockwise from north orientation south, westerly
The longitude and latitude on four vertex and center eastwards.
By the above process, for each atural object in calamity emergency information, title, the shape of the atural object can be obtained
Classification, geographic coordinate information, affiliated every grade administrative area, the calamity emergency information at place and the calamity emergency information at place
Type, the corresponding calamity emergency demand data as the atural object.
Step S2 establishes the base map of the thematic maps of calamity emergency demand.
The thematic maps of calamity emergency demand may include two-part information：A part is the information of atural object itself, separately
A part is the corresponding calamity emergency demand information of atural object.
The information of atural object itself can be obtained by remote sensing image.Preferably, it is obtained by high spatial resolution remote sense image
It takes.
After the generation of the disasters such as earthquake, the information of atural object itself can change.Such as：House collapse, road landslide, shape
At barrier lake etc..Therefore, it is necessary to the high spatial resolution remote sense images after being occurred according to disasters such as earthquakes, obtain newest atural object
The information of itself.
Usually, as unit of certain administrative area, the remote sensing image in disaster area is obtained.By the interpretation to remote sensing image,
It will be superimposed upon in the face figure layer in disaster area, obtain related to all types of calamity emergency demands from the thematic information obtained in remote sensing image
Thematic information map, as base map.
Specifically, to the interpretation of remote sensing image, object-oriented point may be used in the thematic information obtained from remote sensing image
Class technology identifies the various thematic informations in remote sensing image.
In order to make the calamity emergency demand information matching corresponding with atural object of the information of atural object itself, remote sensing image use big
Ground coordinate system is identical as the earth coordinates that place name look-up table uses are pre-established.
For example, when establishing place name look-up table and using WGS-84 coordinate systems, the high spatial resolution remote sense image in disaster area
Also it is acquired under WGS-84 coordinate systems.
The unit for the remote sensing image for obtaining disaster area is determined generally according to disaster-stricken range.It can be by disaster-stricken minimum administrative area
Unit of the common upper level administrative area as the remote sensing image for obtaining disaster area, but not limited to this.For example, working as disaster-stricken ranging from one
It, can be using this county as the unit for the remote sensing image for obtaining disaster area when multiple townshiies in county；When the one of disaster-stricken ranging from one county
It, can be using this county or the township as the unit for the remote sensing image for obtaining disaster area when a township.
The information of atural object itself and the corresponding calamity emergency demand information of atural object are overlapped, i.e., by VGI numbers by step S3
It is polymerize according to remote sensing image data, generates the thematic maps of all types of calamity emergency demands.
Calamity emergency demand can be divided into different type.Such as：Great casualties rescue demand, emergent evacuation of people and peace
Set demand and great medical aid demand etc..
If corresponding with Ganlei's calamity emergency information per class calamity emergency demand.That is, if Ganlei's calamity emergency is believed
Breath reflects same class calamity emergency demand.
Seek to rescue class calamity emergency information for example, " 5 people's conditions of the injury of the villages L of the counties K of the cities J of I provinces are heavier, need to give treatment in time " belongs to,
Reflect great casualties rescue demand；" cities B of the A provinces areas the C streets D 40 are homeless ", which belongs to, seeks to rescue class calamity emergency letter
Breath, reflects emergent evacuation of people and placement demand.
In step S1, the calamity emergency demand data of whole atural objects in same type calamity emergency information can be carried out
Induction-arrangement generates the type corresponding figure layer of calamity emergency information.It can be by GIS platform, such as ArcMap, by each
The geographic coordinate information of object is converted to an element, to which the atural object to be added in a figure layer.Each point element includes attribute
Table, attribute list include the corresponding calamity emergency demand data of atural object.
Preferably, it puts in figure layer, each point indicates a calamity emergency information；The classification of the legend display point of point, indicates
The type of calamity emergency information；The size of legend indicates the order of importance and emergency of demand；The color of legend is for distinguishing under same category
Subclass.
By GIS platform, it will reflect the corresponding point of calamity emergency information all types of each type calamity emergency demand
Figure layer is superimposed upon on the map of the thematic maps of the type calamity emergency demand, generates the special topic of the type calamity emergency demand
Map.
It is understood that not depending on specific sequencing between step S1 and step S2, that is, held after executing step S2
Row step S1 executes step S2 after executing step S1, or is performed simultaneously step S1 and step S2, can realize offer of the present invention
Thematic maps generation method.
The embodiment of the present invention passes through the VGI data and remote sensing image data in the polymerization disaster area under identical earth coordinates, energy
It realizes the thematic maps for quickly generating all kinds of calamity emergency demands, to intuitively reflect the emergency management and rescue demand in disaster area, is conducive to special
