The mini program map interface integrates positioning, search, navigation and point of interest display and other functions. Users can view the current location in real time, query the target location, and plan walking. The interface supports map mode switching, point of interest display and custom markers, providing smooth interactive experience and multi-language support. This interface is suitable for travel navigation
(1) Map module integration
Map location clustering is a technology that classifies and integrates geographic location data according to specific rules, often used to optimize location-related applications, such as map navigation, location recommendation, and business display. Its core purpose is to group multiple locations that are geographically close or have similar characteristics in order to better present information, improve system efficiency, or improve user experience.

Clustering principle
Clustering refers to the grouping of a set of geographic location data points by their spatial location or other characteristics (such as category, purpose, etc.). Common clustering algorithms include K-means, DBSCAN, hierarchical clustering and so on. These algorithms automatically divide geographic locations into clusters by calculating the similarity or distance between locations, with locations in each cluster having a high degree of similarity.

  this.mapCtx = wx.createMapContext('map');              // 地图上下文
  this.mapCtx.includePoints({
    padding: [100, 40, 20, 40], // 地图视野的边距
    points: points,             // 包括的所有坐标点
  });

    var ret = res.result.routes[0]; // 获取规划结果

    var pl = [{                    // 初始化路径点串，添加起点
      latitude: e.detail.value.start.split(",")[0],
      longitude: e.detail.value.start.split(",")[1],
    }];
    // 解压缩路径点串
    var kr = 1000000;
    for (var i = 2; i < coors.length; i++) {
      coors[i] = Number(coors[i - 2]) + Number(coors[i]) / kr;
    }
    // 将解压后的路径点依次存入 `pl` 数组
    for (var i = 0; i < coors.length; i += 2) {
      pl.push({
        latitude: coors[i],
        longitude: coors[i + 1],
      });

    // 更新 `polyline` 数据，显示路径
    _this.setData({
      polyline: [{
        points: pl,

1.2.2 Improve homepage fluency and accuracy

Home interface design is simple and intuitive, the top display Fuzhou University image and emblem, and provide a school introduction entrance, convenient for users to quickly understand the school information. Functional modules include map navigation, campus guide, location popularity and friendly links to meet users’ needs for campus travel and information inquiry. It also displays real-time weather information in Fuzhou, Fujian Province, and the bottom navigation bar provides a shortcut entry for users to quickly access related functions.

Optimize weather models with machine learning and data assimilation to improve forecast accuracy. High-resolution weather models and automated correction systems can also adjust data in real time to enhance forecast accuracy.

// 获取天气
    getWeather() {
        var that = this
        wx.request({
            url: 'https://devapi.qweather.com/v7/weather/now?key=' + that.data.APIKEY + "&location=" + that.data.school_location,
            success(result) {
                var res = result.data
                that.setData({
                    now: res.now
                })
            }
        })
    }

• Test range
  Stability test: Simulate high concurrent user access and test the performance of the system under peak load.
  Response speed testing: Measures the average time it takes a system to process a request to ensure that performance standards are met.

• Test results
  Stability test results:
  The system performs stably under standard loads without crashes or abnormal outages.In the high load test, the system has a slight performance degradation, but does not affect the normal operation of the core function.
  

1.3 Questionnaire survey feedback collection

The application of questionnaires in small programs is mainly used to collect user feedback. Through structured questions, users can efficiently obtain comments on the functionality, interface, and performance of the applet, helping the development team identify problems, optimize the experience, and improve the product.
