篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了图像处理软件erdas如何使用?相关的知识,希望对你有一定的参考价值。
我是遥感初学者 对于图像处理了解不多 要如何才能使用erdas呢?有没有什么教程啊?最好是电子版的
参考技术A 这有个http://www.eshuba.com/soft/10733.htm 参考技术B 有呀。在Google上百度一下就有了。。。mac单节点安装Erda实践
一、安装环境
1、官方最低要求
- Docker 版本:20.10.0 及以上
- 节点配置:4 核 CPU,8 GB 内存
2、自己实际环境
1、硬件环境
2、软件环境
二、安装文档
因为是自己机器安装,机器配置一般,所以只能选择 Docker Compose安装。
三、安装步骤
1、执行脚本
打开自己的iTerm2运行如下脚本
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/erda-project/erda/master/quick-start/quick-start.sh)"
遇到问题一:执行过程中有可能(如果网络正常就不会碰到)碰到443错误,如下图所示
原因:网络偶尔有异常(raw.githubusercontent.com 域用于提供存储在GitHub存储库中的文件的未处理版本)
解决:两种方式
- 方式一:搭建翻墙工具或者切换网络(我的情况是网络有异常,什么都没操作过了一会自己就正常)
- 方式二:将下面shell保存到本地,然后运行。但是远程erda的脚本有可能变更;

echo "goto ${INSTALL_LOCATION}/quick-start/ dir to check and manage the docker-compose resources"
效果:刷刷刷,程序运行起来了,如下图
遇到问题二:文件夹缺少权限
现象:文件 is not shared ,具体如下
Creating erda-migration ... error
ERROR: for erda-migration Cannot start service erda-migration: Mounts denied:
The path /opt/erda-quickstart/.erda/migrations is not shared from the host and is not known to Docker.
You can configure shared paths from Docker -> Preferences... -> Resources -> File Sharing.
See https://docs.docker.com/docker-for-mac for more info.
ERROR: for erda-migration Cannot start service erda-migration: Mounts denied:
The path /opt/erda-quickstart/.erda/migrations is not shared from the host and is not known to Docker.

See https://docs.docker.com/docker-for-mac for more info.
ERROR: Encountered errors while bringing up the project.
Failed during: docker-compose up erda-migration
原因:erda安装过程中会创建一个/opt/erda-quickstart文件夹,但是该文件夹没有被shared,导致docker执行文件夹下命令时候Mounts denied
解决:将该文件夹shared,操作Docker -> Preferences… -> Resources -> File Sharing.如下图
文件夹共享后,可以重新执行下/bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/erda-project/erda/master/quick-start/quick-start.sh)” 最终看到successfully
2、访问平台
浏览器上直接访问 http://erda.local
注:erda安装过程中给本机hosts里添加了一行数据,所以可以通过上面域名访问
127.0.0.1 erda.local one.erda.local
系统进入一个登录页面,没有账密(erda为何不给数据库中主动插入一条账户数据呢?),选择注册用户,注册成功后进入主页
遇到问题一:当前页面不存在
http://one.erda.local/-/sysAdmin/orgs
问题原因:注意到该页面地址为 sysAdmin/orgs,即超级管理员管理页,该模块暂时还未包含在开源包内(我们将在近期开放该模块)。Erda 首次注册到账号会默认成为超级管理员,因此会自动尝试跳转到该页面。
解决方法:您可以退出首次注册的账号,然后再次注册一个新账号,使用新的账号登录后将会跳转到个人仪表盘页面,如下图所示,您可以从点击页面左上方的 创建机构 按钮开始体验 Erda。
重新注册第二个用户后终于可以正常使用。PS第一个账户注册时候密码没有要求,注册第二个账户密码有一定长度+强弱要求;
后续其他操作见erda官网文档

请问使用ERDAS软件进行遥感影像数据可视化、分类时,具体的一个软件使用流程是怎样的?跪求高手指点!
