0.引言

ArcGIS for JavaScript（或简称AGJS）是一个强大的工具，它允许开发者使用JavaScript在Web浏览器中创建和运行ArcGIS应用程序。ArcGIS Server是一个强大的服务器产品，它提供了许多服务，包括地理处理服务（GP服务）。GP服务是一种服务，它允许开发者在ArcGIS Server上运行各种地理处理任务等。ArcGIS for JS可以使用ArcGIS Server发布的GP服务来执行各种地理处理任务。

1.ArcGIS创建GP服务

（1）创建mxd地图文档，命名为bufferGP。

（2）创建点要素

（3）创建模型

构建点生成缓冲区的模型。

设置heatPoints。

设置距离[值或字段]。

设置各组件显示模型参数。

同理设置其他组件的模型参数。

重命名各组件。

运行成功并退出。

2.ArcGIS Server发布GP服务

打开模型，执行一次模型。

打开结果查看会话。

发布地理处理服务。

在ArcGIS Server查看GP服务。

地理处理服务地址：http://localhost:6080/arcgis/rest/services/gp/bufferService1/GPServer/bufferGPModel

3.ArcgisForJS使用ArcGIS Server发布的GP服务

（1）实现代码
