在数据收集过程中,照片往往是需要收集的重要信息。然而,大照片会迅速增加数据库的大小,导致上传和同步时间变慢。但你需要那张照片!选择照片大小以捕获所需内容,并将其对数据库的影响降至最低。注意:虽然照片可能很大,存储费用取决于数据的大小,但附件(包括照片)的存储费用比功能数据本身的每GB要低。所有三个用于数据收集的ArcGIS应用程序都支持自定义照片大小。在ArcGIS Survey123中,你可以用几种方式控制图像大小:在Survey123 Connect中,你可以在Options选项卡中为所有照片设置最长边的最大大小(以像素为单位)。在Survey123 Connect或浏览器中,您可以为每个图像问题设置最大文件大小(以MB为单位)。这将只在浏览器中收集数据时使用。在这两种情况下,这只适用于通过Survey123拍摄的照片。 Photos that were added from the device use their original file type, resolution, and quality. Learn more about restricting the image sizes in Survey123 Connect in Media questions > Images. In the browser, you'll find the File size > Maximum setting at the bottom of the Validation section for configuring an Image question. ArcGIS Field Maps In ArcGIS Field Maps, there are a couple of ways to set the photo size: The map author can set it as a part of the App settings specified during map configuration. See Configure the map > Specify photo size. The data collector can set it in the mobile app's settings. See Configure the mobile app > Specify photo size. (If the map author has provided a size, the mobile app defaults to it when the map is open. Details for how to override the map author's setting and use a device setting instead are included in that linked topic.) In both cases, the size is applied not only to photos taken through the app but is also used as the max size if uploading a photo to a feature. ArcGIS QuickCapture In ArcGIS QuickCapture, you can set the photo size for all photos captured through the project. While configuring the project, go to the General settings and set the Photo size. --- And that's it! Now, no matter which field app you use, you can configure your photos to meet your project requirements.

当在教室里使用ArcGIS时,一天的基调取决于让每个人登录并准备好上课的容易程度。我花了很多时间帮助早期的小学生,轻松记住密码是关键!在创建帐户时,我可以为他们设置强大但简单的密码。然而,当他们第一次登录时,他们会被提示更改它们!突然间,房间里的人再也不会知道他们的密码了……那么,我们如何为学生设置他们能记住且不会被提示更改的密码呢?最好的方法是使用单点登录(SSO)来创建帐户。(该软件使用与其他学校软件相同的密码,避免了学生只需要为ArcGIS学习一个帐户或密码。)然而,并不是所有的学校和地区都可以这样做。本博客将介绍SSO不适用时的选项。 Without SSO, a common approach is to sign in to each account after it is created and reset the password for them. But when creating 100 or more accounts, I don't want to undertake that Sisyphean task. Another option is to create or update the accounts through Python scripting, contained in an ArcGIS Notebook. In a script, you can update the password and set the security question, and then the students won't be prompted to do so when they log in. Download my notebook to see the full code. I've included comments to help you understand it. However, keep in mind that running a notebook is a more advanced task, so proceed with caution. Updating the account is the key part of the code, so let's take a look at that line, using arcgis.gis.User.reset: account.reset(password=passwordFinal+'TEMP', new_password=passwordFinal, new_security_question='1', new_security_answer='Your City') This assumes an account password of the final password, followed by TEMP. It then sets the password to the final, desired permanent password, and sets the security question. Security question option 1 is "What city were you born in?" and using that, with an answer of the city where your school is, has served me well. (If you'd like to see all the security choice options, they are listed out as part of the parameters for arcgis.gis.User.update.) Keep in mind that the final password is only as secure as your script makes it. If you are working with older students likely to sign in as other students maliciously, you'll want to choose something safer than password format proposed in the script. So one line of python that does the heavy lifting, and many fewer password resets in your future!

我们都见过学生试图搞笑,但行为不当。如果你还没看过,请任何一个班级填写一份关于昵称和图片的2个问题的调查。那么,我们如何从课堂上获得数据,而不把这些小丑的作品放在其他学生面前呢?添加审查步骤,以便只与类共享已批准的数据。添加评审步骤是一个简单但复杂的过程。(如果你看过我做的演示或其他博客,你现在可能知道我的意思是会有一些步骤,但我会牵着你的手——只要你注意,你就会得到这个!然而,如果你害怕漫长的过程,这可能不适合你。)那么,我们如何在审查过程中创建一个调查呢?以下是重点:像你通常做的那样做一份调查。将一个字段添加到存储数据中,无论该数据是否被审查。 After entries are submitted, review each submission and mark it as approved or rejected. There are a number of ways to review the data, but I find using a dashboard is a pretty slick way to do so, especially when you have a high volume of data and want to have a list of just what is left to review. Create a layer view that only includes the approved data, and use it in maps and apps for your class to see. Want to try it out for yourself? Head over to this dashboard to see how it works once all set up: you'll submit the survey, review your entry, then see it in the approved results. Are you ready to see the full implementation details? Head back to the dashboard and expand the section at the bottom of the survey. Questions? Just leave a comment here. These are wrapped into a single dashboard to give you one place to see the workflow. In reality, your survey will be handed out as it always is, the dashboard will just be for your use, and you'll use the approved results the same way you use results today.

我最近为小学STEM之夜提供了绘图活动。为了将它们呈现给学生,我考虑了几个选项:ArcGIS StoryMap Collection和ArcGIS Hub Gallery。两者都创建了一个简单,易于阅读的页面,让学生探索,选择一个感兴趣的活动,并投入其中。当我收集我想要分享的活动时,我考虑是否应该使用Hub Gallery或StoryMap Collection。我知道这两种方法都可以快速创建一个链接到我想要分享的活动的网页,并显示活动本身的标题和图像。那么如何选择使用哪种呢?要查看每种格式相同内容的示例,您可以查看我为STEM之夜创建的测试站点:STEM之夜的StoryMap Collection Hub Gallery那么哪个更好呢?一个考虑因素是浏览页面的人的经验。学生看到的内容有一些不同:Hub Galleries显示活动描述,但它们在StoryMap Collections中缺失。StoryMap集合具有一致的格式和布局,而枢纽画廊是页面的一部分,无论作者如何决定布局。 StoryMap Collections support some surrounding text but are focused on the activities. Hub Galleries can have as much text and as many varied components around them on the page as the author decides. The other consideration is the work required to create one and the differences in the authoring experience: Upon creation, StoryMap Collections are ready for you to add your resources. In a Hub, you first have to add a Gallery to your page's layout. Configuring the gallery gives you the ability to search for and add content from ArcGIS, showing the title, description, and icon. StoryMap Collections support content in ArcGIS as well as content from outside your ArcGIS account by uploading or linking to images, videos, PDFs, or other embeddable content (like websites and apps). Hub Galleries are limited to content from ArcGIS. Adding items you didn't make into a StoryMap Collection means finding them in ArcGIS Online, favoriting them, then adding them to the collection. (In the StoryMap Collection interface, you can explore your favorites but not all public facing ArcGIS Online content.) During the configuration of a Hub Gallery, you can browse all ArcGIS Online content. A Hub Gallery can be populated manually or dynamically based on a group, tag, category, or content type. This allows you to change the content presented without having to edit the page. The content in a StoryMap Collection is manually selected. Hub Galleries support up to 16 items. StoryMap Collections can have a maximum of 60 items. Once your resources are identified, a StoryMap Collection is ready to go. It only needs a title and an optional bit of text. A Hub Gallery is part of a larger Hub page and requires work to get the page feeling complete. So which one did I use, and how did I choose? For this event, I used the Hub Gallery. I wanted to have more context around the activities, and more information than just activities. Placing additional items into the hub page's layout let me do so (for example, the QR code to use the page at home, and information on how the students could access GIS software). I'm also comfortable creating Hub sites and working in HTML (which can come into play for some Hub layouts), so those weren't hurdles for me. Your choice might differ. What's your comfort level, and what do you need on your page? Here we explored StoryMap Collections and Hub Galleries as ways to distribute activities to students. But those aren't the only use cases for this kind of setup. You can use a similar concept and make a collection of resources you often use, or a progression through activities where students must go in order. Or perhaps you want to gather resources to share with another teacher. Maybe it's even just a way to gather the resources you know you recommend time and time again so that you have one place to quickly access them all. Whatever your need, a Storymap Collection or a Hub Gallery is an effective way to organize and share content and your project and skills will help determine which to use. Now, what do you need to organize?

ArcGIS在线更新本周(2022年3月)!虽然它包含了许多强大的增强功能,但我们希望将您的注意力集中在教育工作者会感到兴奋的子集上。将搜索结果添加到草图图层更改自己内容的所有权呈现新的Exhibit应用程序将主页升级到新模板使用新的编辑工作流更改地图查看器工具栏在地图查看器中使用嵌套的组层组织您的图层关于电子邮件验证的说明在新版本中模仿经典StoryMaps最后一件事让您在课堂上思考应用程序……有关完整的发布信息,请参阅博客ArcGIS Online新功能(2022年3月)或阅读文档中的新功能。(复制图层在地图查看器!键盘快捷键!更多即时应用程序更新!在仪表板中放置元素的新方法!新的体验生成器小部件!会员类别! OK, I'll stop now.) 1. Add search results to sketch layers Search results - Add to sketch Remember in Map Viewer Classic how you could search for something, and then add a map note at that location? It’s now supported in new Map Viewer. Do a search, and at the bottom of the result pop-up you’ll see options for adding it to a new or an existing sketch layer. Read how— Add search results to a sketch layer . 2. Change ownership of your own content When working together in ArcGIS Online, we often recommend that one person works on the map, story, or another piece of content at a time. Once one author is done, the recommended workflow is to change the owner of the item to the next person who needs to work on it. Previously, the admin had to transfer the content to a new owner each time. Now, with appropriate permissions, anyone in the org can change the owner of their own content to another person. Learn more about transferring content between members in an org. 3. Present with the new Exhibit app Exhibit app This is another place where something we’ve all loved in the past is back in a new way. Before, you could create a presentation in your map, and then play the slides to present your map. Now, wrap your map in an Instant app “Exhibit” and you can guide your audience through your map using interactive slides. See Build an interactive map presentation with Exhibit. 4. Upgrade of homepages to the new template If you still have the old (legacy) home page and haven’t switched to the new home page yet, your home page has been automatically replaced with a default, new home page. You can further edit and configure your new home page. See the following blogs and help for details: Still using the legacy home page? Create a great homepage for your organization Fun with GIS 303: Spruce up your homepage (focused on K-12 educators) Configure home page 5. Use new editing workflows Editing gets a big boost with this update. First, in new Map Viewer, snapping is here! And along with it is an enhanced editor pane. (Learn more about editing features in Map Viewer.) In the Attachment Viewer Instant App, you can now edit the attributes when showing the attachments of an editable layer. (Learn more in What’s New in Instant Apps (March 2022).) Editing updates 6. Changes to the Map Viewer toolbar Map tools The new Map Viewer is still evolving, and with this release you’ll see some toolbar changes. On the light toolbar, you’ll find the map tools (Search, Directions, Measurement, and Location) are now grouped into a Map tools category. With the last release, the light toolbar was updated to only show options that work with the layer you have selected, so with both these enhancements the toolbar provides a cleaner experience. 7. Organize your layers with nested group layers in Map Viewer A long-awaited feature is ready: Map Viewer now supports nested group layers, simplifying visualization and review of complex data. 8. A note on email verification You might have seen that your ArcGIS login might start prompting you to verify your email address. And you might be worried about all the student accounts you have where you don’t want them prompted to do so. Don’t worry – while email verification might come up for default org admins, no other users in ArcGIS organizations for instructional use will be asked to do so. This includes Education subscriptions and site licenses, as well as ArcGIS for Schools. 9. Mimicking Classic Esri Story Maps in new ArcGIS StoryMaps The Classic Story Map templates were great, and the StoryMaps team has put together a blog about how to recreate those experiences in the new ArcGIS StoryMaps experience! So if you still need Cascade, or Journal, or another classic template in your life, head over and see how to revive them! 10. One last thing to get you thinking of applications in the c lassroom... flow renderer Jason's flow renderer tweet The animated flow renderer brings a new way to visualize magnitude and direction data in imagery layers. Check out how Jason sees using it in the classroom.

哇,自从我做了“映射最喜欢的颜色”项目以来,已经有两年了吗?起初,我只是想向当时4岁和7岁的孩子们展示我在做什么,后来成为向许多人介绍GIS和数据收集的一个很好的资源。到目前为止,已有超过1400人贡献了积分!在我展示之后,人们很自然地想要添加点并戳戳数据。但下一个问题是“你是怎么做的?”我怎么才能做一个这样的?”我喜欢看到老师们可能想要收集和映射到他们的课堂上的想法,我最后分享了我在这个项目中使用的步骤:https://storymaps.arcgis.com/stories/ca956903ac244b7fb7b4d985c3d8f4e4看看,让我知道你的想法。

你听过多少故事,一个孩子通过拆开一个电子设备来了解一个电子设备?解剖然后重建可以让您亲身了解各个部分是如何一起工作的。您可以将相同的理论应用于仪表板。也许您看到一个仪表板,其中包含列表、量规、图表或其他您想在自己的仪表板中模拟的元素。或者,您可能看到了想要改进的仪表盘。您可以复制仪表板,留下您自己的版本进行编辑和修改。在您的副本中,您可以配置每个元素,并查看作者用于创建它的设置。这甚至包括仪表板用来制作更复杂显示的任何Arcade。复制仪表板相对简单,但是需要使用一些url。找到要复制的仪表板的ID。 To do so, open the dashboard you want to copy. Look at the URL in your browser. At the end of the URL is a long, somewhat meaningless string — that's the ID. For example, my favorite color dashboard is at https://arcgis.com/apps/dashboards/8b1b186fe52c435e95c0301997d271f0. It's ID is 8b1b186fe52c435e95c0301997d271f0. Write a new URL as follows: https://arcgis.com/apps/dashboards/new#id=id_of_the_dashboard_to_copy where id_of_the_dashboard_to_copy is replaced with the ID you found in the previous step. For example, the following URL will make a copy of the favorite color dashboard in your account: https://www.arcgis.com/apps/dashboards/new#id=8b1b186fe52c435e95c0301997d271f0 You are taken to the "Create dashboard" experience, but instead of creating an empty dashboard, you'll create one that matches one whose ID you copied. Fill out the requested information, click "Create dashboard" and you'll be taken to your copy. It's ready for you to dissect it and learn! A few things to understand: The dashboard you are working in is a copy, but it is the same map and data that the original dashboard used. You don't own the data, and you can't change the map. Note: You could, of course, save your own copy of the map and then change your copy of the dashboard to use your map. But that will leave you having to make a number of updates to the elements to link them to your updated data sources. Your changes only affect your copy of the dashboard. The original is unchanged.
