ArcGIS坡度分析出错_百度知道
ArcGIS坡度分析出错
在ArcGIS中，利用等高线生成的DEM栅格文件进行坡度分析，结果总是出错，坡度完全没有差别由等高线生成的DEM文件执行坡度分析的结果是这样的！哪位大大给解释下，哪里出问题了？
我有更好的答案
用百分比输出试试，栅格大小设置的是否合适，再就是到分析环境里面看看有没有设置有误的项
用百分比输出可以的，是什么原因呢
应该是跟你的DEM数据有关，不就是数据本身就这样，或者是格式问题，你可以转成8位正型值试试

要看输入的参数，把做坡度分析时输入参数的界面贴图出来帮你看。或者可以私信我帮你！

OAuth Popup
DescriptionThis sample uses OAuth 2.0 to allow users to log in to the ArcGIS platform via the app. More detailed information about user logins and OAuth 2.0 can be found.
The popup web flow is similar to the &inline& flow, however, the sign in page is within a popup window.
Beginning with version 3.10, support for OAuth2 authentication is provided directly in the ArcGIS for JavaScript API's Identity Manager. This built-in functionality handles a lot of the fine-grained work that you would typically have to do when implementing this type of authentication.
The Identity Manager component simplifies the process of working with the token by appending it to requests and acquiring a new token when necessary. All you need to do is create an
object and specify the appId you received when registering your application. Additionally, you can set the popup property to true if you want to display the OAuth sign-in page in a popup window. After this is set, pass this OAuthInfo object to the IdentityManager's
method and the Identity Manager takes care of the rest.
var info = new OAuthInfo({
appId: &&pass in your application id here&&,
popup: true
esriId.registerOAuthInfos([info]);
The Identity Manager also honors whether or not you choose to remain signed in via a &Keep me signed in& checkbox. This provides the option to save your credentials within local storage so as to not have to repeatedly sign in when accessing the application. If uncertain as to whether a user is already logged in, use the IdentityManager checkSignInStatus method. This method takes a given portal URL and returns the credentials of the user if they are already signed in.
To run this sample on your own web server you need to register your application on ArcGIS.com. Once the application is registered you will get an appid that you use in the sample.

& & & &如下图，对一份数据做坐标系转换：
& & & &过了一会儿，转换失败了。错误消息如下：
& & & &&消息&中提示，&执行函数出错 invalid extent for output coordinate system&，从这句话本人看不出多大的端倪。找高人指点得知，
这份数据的投影坐标是高斯-克吕格投影38度带的，但它的坐标系确是114的（右键地图显示区域，点击数据框属性
& & & & & & & & & & & & & & &&
& & & &显示坐标系为：Xian 1980 3 Degree GK CM 114
& & & & & & & & & & & & &
& & & & 所以，我们必须给这份数据添加一个高斯-克吕格投影38度带的
坐标系，然后再做&投影&（由高斯-克吕格38度带转换为地理坐标系）。
解决方案：
& & & 定义38度投影
& & & 更改应用：定义结束之后，图框内的地图消失了，右键打开&数据框属性&，然后发现其坐标系依然是114的，说明数据框的坐标系还没有更新过来。将数据框的坐标系改为38度，
便可以正确地显示38度的地图了。或者也可以将数据关闭，从新打开一次，也可以正确看到地图。
& & &坐标转化为地理坐标之后，右下角显示的单位可能还是&米&，此时，打开&数据框 属性&，按如下图选中&度十进分制&：
& & & & & & & & & &&
& & & 自此，坐标系转化就算成功了。
