MongoDB地图集搜索-如何过滤搜索分数

MongoDB地图集搜索是MongoDB数据库提供的一种强大的地理位置搜索功能。它允许开发者在地理位置数据上执行复杂的查询和过滤操作,以便快速准确地检索出符合特定条件的地理位置信息。

在进行地图集搜索时,过滤搜索分数是一种常见的需求,它可以帮助开发者根据搜索结果的相关性进行筛选。以下是一种完善且全面的答案示例:

过滤搜索分数可以通过MongoDB地图集搜索中的查询条件进行实现。在MongoDB中,可以使用$geoNear操作符进行地理位置搜索,并结合$match操作符进行筛选和过滤。具体步骤如下:

  1. 创建地理位置索引:在对应的集合上创建地理位置索引,以便加速地理位置搜索。可以使用createIndex方法来创建索引,其中需指定字段为地理位置类型(如2dsphere)。
  2. 构建查询条件:通过构建查询条件来实现过滤搜索分数。查询条件可以包括地理位置参数、搜索关键词以及其他过滤条件。
  3. 执行地图集搜索:使用aggregate方法进行地图集搜索,结合$geoNear操作符和$match操作符来实现地理位置搜索和过滤。
  4. 过滤搜索分数:在查询结果中,可以使用$match操作符再次进行过滤,根据搜索结果的分数来筛选出符合条件的数据。

使用MongoDB地图集搜索进行过滤搜索分数的优势包括:

  • 强大的地理位置搜索功能:MongoDB地图集搜索提供了丰富的地理位置操作符和功能,能够满足各种复杂的地理位置搜索需求。
  • 高性能的查询和过滤:地图集搜索利用地理位置索引和复杂查询操作符,能够快速准确地检索符合条件的地理位置信息。
  • 灵活的应用场景:地图集搜索适用于各种应用场景,如地理位置服务、商业分析、附近搜索等。

  • 中国成人脑白质分区与脑功能图谱

    脑地图集在研究大脑解剖和功能方面起着重要的作用。随着对多模态磁共振成像(MRI)方法(如结合结构MRI、弥散加权成像(DWI)和静息态功能MRI (rs-fMRI))的兴趣的增加,有必要基于这三种成像方式构建集成的脑地图集。本研究构建了中国成年人群(年龄22-79岁,n = 180)的多模态脑图谱,包括反映脑形态学的T1图谱、描绘复杂纤维结构的高角度分辨率弥散成像(HARDI)图谱和反映单一立体定向坐标下大脑固有功能组织的rs-fMRI图谱。我们采用大变形自形度量映射(LDDMM)和无偏自形图谱生成方法同时生成T1和HARDI图谱。利用谱聚类,我们从rs-fMRI数据中生成了20个脑功能网络。我们通过联合独立成分分析,展示了使用图谱来探索大脑形态、功能网络和白质束之间的一致性标记。

    Google Earth Engine——全球摩擦面列举了北纬85度和南纬60度之间的所有陆地像素在2015年的名义年的陆地迁移速度。

    This global friction surface enumerates land-based travel speed for all land pixels between 85 degrees north and 60 degrees south for a nominal year 2015. This map was produced through a collaboration between the University of Oxford Malaria Atlas Project (MAP), Google, the European Union Joint Research Centre (JRC), and the University of Twente, Netherlands. The underlying datasets used to produce the map include roads (comprising the first ever global-scale use of Open Street Map and Google roads datasets), railways, rivers, lakes, oceans, topographic conditions (slope and elevation), landcover types, and national borders. These datasets were each allocated a speed or speeds of travel in terms of time to cross each pixel of that type. The datasets were then combined to produce this “friction surface”, a map where every pixel is allocated a nominal overall speed of travel based on the types occurring within that pixel, with the fastest travel mode intersecting the pixel being used to determine the speed of travel in that pixel (with some exceptions such as national boundaries, which have the effect of imposing a travel time penalty). This map represents the travel speed from this allocation process, expressed in units of minutes required to travel one meter. It forms the underlying dataset behind the global accessibility map described in the referenced paper.

    NC:生理高频振荡和慢波之间的相-幅耦合的发育图谱

    摘要:我们研究了高频振荡(HFO)和调制指数(MI)(HFO与慢波相位之间的耦合测量)的发展变化。我们利用114名患者(年龄1.0-41.5岁)的8251个非癫痫电极部位的硬膜下脑电图信号生成了标准脑图谱,这些患者在癫痫切除手术后实现了癫痫发作控制。我们观察到所有年龄段的枕叶MI均较高,并且枕叶MI在儿童早期显着增加。表现出MI共同生长的皮质区域通过垂直枕叶束和后胼胝体纤维连接。虽然枕叶HFO没有显示出显着的年龄相关性,但颞叶、额叶和顶叶的HFO却表现出与年龄相反。对1006个癫痫发作部位的评估显示,癫痫发作时的z评分归一化MI和HFO高于非癫痫电极部位。

    Google Earth Engine——北纬85度和南纬60度之间所有地区到最近的人口密集区的迁移时间数据集

    This global accessibility map enumerates land-based travel time to the nearest densely-populated area for all areas between 85 degrees north and 60 degrees south for a nominal year 2015. Densely-populated areas are defined as contiguous areas with 1,500 or more inhabitants per square kilometer or a majority of built-up land cover types coincident with a population centre of at least 50,000 inhabitants. This map was produced through a collaboration between the University of Oxford Malaria Atlas Project (MAP), Google, the European Union Joint Research Centre (JRC), and the University of Twente, Netherlands. The underlying datasets used to produce the map include roads (comprising the first ever global-scale use of Open Street Map and Google roads datasets), railways, rivers, lakes, oceans, topographic conditions (slope and elevation), landcover types, and national borders. These datasets were each allocated a speed or speeds of travel in terms of time to cross each pixel of that type. The datasets were then combined to produce a “friction surface”, a map where every pixel is allocated a nominal overall speed of travel based on the types occurring within that pixel. Least-cost-path algorithms (running in Google Earth Engine and, for high-latitude areas, in R) were used in conjunction with this friction surface to calculate the time of travel from all locations to the nearest city (by travel time). Cities were determined using the high-density-cover product created by the Global Human Settlement Project. Each pixel in the resultant accessibility map thus represents the modeled shortest time from that location to a city.
