从mapbox中的csv导入iconurl [英] importing iconurl from a csv in mapbox
本文介绍了从mapbox中的csv导入iconurl的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想将一些标记导入到mapbox地图上，其中csv文件定义要使用的图标的名称。 csv表如下所示：
pID，qID，经度，纬度，方位，icon
PID1，QID35,90.39210677,23.7756582,80.1120824,8,3,3.png
PID1，QID40,90.39045721,23.77525565,216.2854365,22,6,6.png
我使用omnivore将这个csv转换为geojson（至少我认为这是omnivore所做的）
我使用的代码如下：
<！DOCTYPE html>
< html>
< head>
< meta charset = utf-8 />
< title>导入数据的自定义标记样式< / title>
< meta name ='viewport'content ='initial-scale = 1，maximum-scale = 1，user-scalable = no'/>
< script src ='https：//api.tiles.mapbox.com/mapbox.js/v1.6.4/mapbox.js'>< / script>
< link href ='https：//api.tiles.mapbox.com/mapbox.js/v1.6.4/mapbox.css'rel ='stylesheet'/>
< style>
body {margin：0; padding：0; }
#map {position：absolute; top：0; bottom：0; width：100％; }
< / style>
< / head>
< body>
< script src ='https：//api.tiles.mapbox.com/mapbox.js/plugins/leaflet-omnivore/v0.2.0/leaflet-omnivore.min.js'>< / script> ;
< div id ='map'>< / div>
< script>
var southWest = L.latLng（23.7，90.2），
northEast = L.latLng（23.9，90.7），
bounds = L.latLngBounds（southWest，northeast）;
var map = L.mapbox.map（'map'，'bakr89.imia9old'，{
maxBounds：bounds，
maxZoom：17，
minZoom： 14
}）。setView（[23.775507，90.3909]，16）;
// Omnivore会AJAX请求这个文件后台并解析它：
//注意有注意事项：
// - CSV文件必须包含纬度和经度值，在列
//命名大致纬度和经度
// - 该文件必须在与请求的页面相同的域，
//或两者的服务器并且用户的浏览器必须
//支持CORS。
var csvdata = omnivore.csv（'csvmarker.csv'），
var myLayer = L.mapbox.featureLayer（csvdata）.addTo（map）
var myIcon = L.icon（{
iconUrl：'csvdata.icon'，
iconSize：[40，40]，
iconAnchor：[20，20]，
popupAnchor：[0，-25]，
}）;
//根据要素属性在每个标记上设置自定义图标。
myLayer.on（'layeradd'，function（e）{
var marker = e.layer，
feature = marker.feature;
marker.setIcon L.icon（feature.properties.icon））;
}
）;
//向地图添加要素。
myLayer.setGeoJSON（csvdata）;
< / script>
< / body>
< / html>
我不是一个编码器，一直在搞乱mapbox约一个星期。
解决方案在csv的情况下正确使用omnivore是
var southWest = L.latLng（23.7，90.2），
northEast = L.latLng（23.9， 90.7），
bounds = L.latLngBounds（southWest，northast）;
var map = L.mapbox.map（'map'，'bakr89.imia9old'，{
maxBounds：bounds，
maxZoom：17，
minZoom： 14
}）。setView（[23.775507，90.3909]，16）;
omnivore.csv（'csvmarker.csv'）。addTo（map）;
I want to import a number of markers onto a mapbox map, where a csv file defines the name of the icon to use. The csv table looks like this:
pID,qID,longitude,latitude,bearing(degree),orientation(36),color,icon
PID1,QID35,90.39210677,23.7756582,80.1120824,8,3,3.png
PID1,QID40,90.39045721,23.77525565,216.2854365,22,6,6.png
I am using omnivore to convert this csv to geojson (at least I think that's what omnivore is doing)
The code I'm using is down below:
<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>Custom marker styles for imported data</title>
<meta name='viewport' content='initial-scale=1,maximum-scale=1,user-scalable=no' />
<script src='https://api.tiles.mapbox.com/mapbox.js/v1.6.4/mapbox.js'></script>
<link href='https://api.tiles.mapbox.com/mapbox.js/v1.6.4/mapbox.css' rel='stylesheet' />
<style>
body { margin:0; padding:0; }
#map { position:absolute; top:0; bottom:0; width:100%; }
</style>
</head>
<body>
<script src='https://api.tiles.mapbox.com/mapbox.js/plugins/leaflet-omnivore/v0.2.0/leaflet-omnivore.min.js'></script>
<div id='map'></div>
<script>
var southWest = L.latLng(23.7, 90.2),
northEast = L.latLng(23.9, 90.7),
bounds = L.latLngBounds(southWest, northEast);
var map = L.mapbox.map('map', 'bakr89.imia9old', {
maxBounds: bounds,
maxZoom: 17,
minZoom: 14
}).setView([23.775507, 90.3909], 16);
// Omnivore will AJAX-request this file behind the scenes and parse it:
// note that there are considerations:
// - The CSV file must contain latitude and longitude values, in column
// named roughly latitude and longitude
// - The file must either be on the same domain as the page that requests it,
// or both the server it is requested from and the user's browser must
// support CORS.
var csvdata = omnivore.csv('csvmarker.csv'),
var myLayer = L.mapbox.featureLayer(csvdata).addTo(map)
var myIcon = L.icon({
iconUrl: 'csvdata.icon',
iconSize: [40, 40],
iconAnchor: [20, 20],
popupAnchor: [0, -25],
});
// Set a custom icon on each marker based on feature properties.
myLayer.on('layeradd', function(e) {
var marker = e.layer,
feature = marker.feature;
marker.setIcon(L.icon(feature.properties.icon));
}
);
// Add features to the map.
myLayer.setGeoJSON(csvdata);
</script>
</body>
</html>
I'm not a coder, and I've been messing around with mapbox for about a week. Do you guys think you can help with seeing what's missing in this code.
解决方案 Proper use of omnivore in the case of csv is like that
var southWest = L.latLng(23.7, 90.2),
northEast = L.latLng(23.9, 90.7),
bounds = L.latLngBounds(southWest, northEast);
var map = L.mapbox.map('map', 'bakr89.imia9old', {
maxBounds: bounds,
maxZoom: 17,
minZoom: 14
}).setView([23.775507, 90.3909], 16);
omnivore.csv('csvmarker.csv').addTo(map);
