关于
安装
Composer /Artisan
或者
composer require equi/opengeodb-laravel
在 composer.json 中添加行 "equi/opengeodb-laravel": "~1.0"
...
"require": {
"php": ">=5.5.9",
"laravel/framework": "5.2.*",
....
"equi/opengeodb-laravel": "~1.0",
...
},
...
手动更新时,请执行该命令
composer update
在 /config/app.php 的 "providers" 数组中添加此行
Equi\Opengeodb\OpengeodbServiceprovider::class,
然后,将 default configs/migrations/.. 复制到 /app 目录。
php artisan vendor:publish
查找缺失的文件
你们需要哪些文件?
必需
opengeodb-end.sql
opengeodb_hier.sql
changes.sql
根据需要加载各个国家的文件
AT.sql
AThier.sql
BE.sql
BEhier.sql
CH.sql
CHhier.sql
DE.sql
DEhier.sql
LI.sql
LIhier.sql
Extra.sql // Übergeordnete inhalte (Europa, Amerika, ...) und dazugehörige Sprachen (Deutschland = Germany ...)
这些文件似乎已过时,但将在 changes.sql 中更新
放哪里?
默认情况下在 /Storage/app/opengeodb/sql 或配置文件中指定的 storageopengodbsql 下的文件夹
配置 config/opengeodb.php
return [
// Storage/app/.....
'storagemap' => "/opengeodb/map",
'storagee00' => "/opengeodb/e00",
'storageopengodbsql' => "/opengeodb/sql",
'mapcolor' => [
'black'=>[0, 0, 0],
'white'=>[255, 255, 255],
'Therme'=>[255, 0, 0],
'Freizeitbad'=>[178, 237, 90],
'Sauna'=>[148, 208, 255],
'Anderes Bad'=>[148, 208, 255],
'Bad'=>[148, 208, 255],
'Hallenbad'=>[148, 208, 255],
'yellow'=>[148, 208, 255],
'pink'=>[148, 208, 255],
'land'=>[20, 20, 20],
'bund'=>[125, 125, 125],
'kreis'=>[200, 200, 200],
],
'incresscolor' => 'black',
'radiusdata' => [
1 => 7,
2 => 10,
5 => 14,
]
];
创建和填充数据库
composer dump-autoload
php artisan migrate
php artisan db:seed --class=OpengeodbSeeder
对于某些PHP配置,de.sql 文件太大,可以尝试以下方法
php -d memory_limit=256M artisan db:seed --class=OpengeodbSeeder
引入/使用
绘制地图
示例显示了一个在 routes.php 中对 /Karte/ 响应的控制器。

这是我现在降低加载时间的方法。点在 map.blade.php 中。
- 要仅显示德国的地图,可以简单地调用 /Karte/show/105 (250px)。
- <img src="{{URL::Asset('/karte/show/' . $demaps[$x]->loc_id)}}" alt="地图 {{$demaps[$x]->GeodbMaster()->name()}}">
- 请将其放入 for 循环中或用数字替换 $x。
- 在函数 /Karte/showbig/105 (1090px) 中还会绘制更多的点。
- <img src="{{URL::Asset('/karte/showbig/' . $demaps[$x]->loc_id)}}" alt="地图 {{$demaps[$x]->GeodbMaster()->name()}}" usemap="#map-{{$demaps[$x]->loc_id}}">
- 请将其放入 for 循环中或用数字替换 $x。
- 在函数 /Karte/json/105 中,我还以 JSON 格式返回单个点。
- <map name="map-{{$demaps[$x]->loc_id}}" id="map-{{$demaps[$x]->loc_id}}">
function gethtmlmap(id){
$.ajax({
url: "{{URL::asset("/karte/json")}}/" + id,
}).done(function(data) {
$("#map-" . id).html("");
for(i=0; i < data.data.length; i++){
area = $("#map-" + data.id).append("<area shape='circle' href='#' coords='" + data.data[i].x + "," + data.data[i].y + "," + (data.data[i].r + 10) + "' id='area" + data.data[i].x + data.data[i].y + data.data[i].r + "' data-id='" + i + "'>");
$("#area" + data.data[i].x + data.data[i].y + data.data[i].r).mouseover(function (){
UIkit.notify(data.data[$(this).data("id")].objects, {status:'info'});
});
}
});
}
- Einfach als Javascript gethtmlmap($demaps[$x]->loc_id) aufrufen um an das JSON für die Karte zu kommen.
- UIkit.notify(....); setzt ein kleines notify am Kopf der Seite ab. (benötigt uikit)
获取数据/计算距离
方法 1
$geoloc = GeodbCoordinate::where("loc_id", $geotext->loc_id)->first();
$entrys = Location::select(\DB::raw("*, round(IFNULL((ACOS((SIN(RADIANS(" . $geoloc->lat ."))*SIN(RADIANS(lat))) + (COS(RADIANS(" . $geoloc->lat ."))*COS(RADIANS(lat))*COS(RADIANS(lon)-RADIANS(" . $geoloc->lon .")))) * 6371.110 ),0),2) AS distance"))->get();
Location 模型具有 lat 和 lon 字段,以避免始终搜索 100 MB 的数据。
方法 2
$augsburg = (new GeodbMaster())->searchByName("augsburg")->first();
$munich = (new GeodbMaster())->searchByPLZ(81929)->first();
$distanz = $augsburg->GeodbCoordinate()->calculatedistance($munich->GeodbCoordinate()->lon, $munich->GeodbCoordinate()->lat);
