- 1、全部查询
- 2、属性字段查询
- 三、空间查询
- 1、根据query结果查询
- 2、点查询
- 3、线查询
- 4、面查询

- 2、geometryType
以arcgis 提供的地图服务为例 http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer
一、返回的数据类型
var result = {
displayFieldName: "STATE_NAME",
features: [……],
fieldAliases: {……},
fields: [],
geometryType: "esriGeometryPolygon",
spatialReference: {
wkid: 4269
}
二、属性查询
1、全部查询
“where”: “1=1”,
var url = "http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer"
url += "/" + "5"+ "/query"; // states 查询
var params = {
"f": "json",
"where": "1=1",
"returnGeometry": "true",
"outFields": "*"
};
$.ajax({
url:url,
type:'post',
data:params,
dataType: "json",
success: function(data){
console.log(data);
//var features = new ol.format.EsriJSON().readFeatures(data);
//console.log(features);
}
})
2、属性字段查询
- “where”: “STATE_NAME=‘Hawaii’”,
- “where”: “STATE_NAME like ‘%H%’”,
- “where”: “STATE_NAME=‘Hawai_’”,
参考：在 ArcGIS 中使用的查询表达式的 SQL 参考
三、空间查询
1、根据query结果查询
// 坐标需与查询图层的坐标系对应
var geometry = result.features[0].geometry;
geometry = JSON.stringify(geometry);
var geometryType = result.geometryType;
var url = "http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer"
url += "/" + "5"+ "/query"; // states 查询
var params = {
"f": "json",
"geometry": geometry ,
"geometryType": geometryType,
"spatialRel": "esriSpatialRelIntersects", // 相交、可选择其他的
"returnGeometry": "true",
"outFields": "*"
};
$.ajax({
url:url,
type:'post',
data:params,
dataType: "json",
success: function(data){
console.log(data);
//var features = new ol.format.EsriJSON().readFeatures(data);
//console.log(features);
}
})
2、点查询
获取点（-100，40）所在的州?
Kansas(堪萨斯州)
// 坐标需与查询图层的坐标系对应
var center = [-100,40];// 坐标需与查询图层的坐标系对应
var geometry = "{'x':" + center[0] + ",'y':" + center[1] + "}";
var geometryType = "esriGeometryPoint";
var url = "http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer"
url += "/" + "5"+ "/query"; // states 查询
var params = {
"f": "json",
"geometry": geometry ,
"geometryType": geometryType,
"spatialRel": "esriSpatialRelIntersects", // 相交、可选择其他的
"returnGeometry": "true",
"outFields": "*"
};
$.ajax({
url:url,
type:'post',
data:params,
dataType: "json",
success: function(data){
console.log(data);
//var features = new ol.format.EsriJSON().readFeatures(data);
//console.log(features);
}
})
3、线查询
从点（-100，40）到点（-80，40）之间，经过的州有哪些？
Nebraska、Pennsylvania、Indiana、Ohio、Illinois、West Virginia、Kansas、Missouri
内布拉斯加州，宾夕法尼亚州，印第安纳州，俄亥俄州，伊利诺伊州，西弗吉尼亚州，堪萨斯州，密苏里州
// 坐标需与查询图层的坐标系对应
// var geometry = {paths:[[[-100,40],[-80,40]]]};
// var geometryStr = JSON.stringify(geometry);
var geometry = '{"paths":[[[-100,40],[-80,40]]]}';
var geometryType = "esriGeometryPolyline";
var url = "http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer"
url += "/" + "5"+ "/query"; // states 查询
var params = {
"f": "json",
"geometry": geometry,
"geometryType": geometryType ,
"spatialRel": "esriSpatialRelIntersects",
"returnGeometry": "true",
"outFields": "*"
};
$.ajax({
url:url,
type:'post',
data:params,
dataType: "json",
success: function(data){
console.log(data);
//var features = new ol.format.EsriJSON().readFeatures(data);
//console.log(features);
}
})
4、面查询
与华盛顿州相接触的州有哪些？
Oregon （俄勒冈州）、Idaho（爱达荷州）
// 坐标需与查询图层的坐标系对应
// Washington（华盛顿州）面数据
// var geometry = {rings:[[[x,y],[x1,y1]],[[x2,y2],[x3,y3]]]}
// var geometryStr = JSON.stringify(geometry);
