Overview
Overview
The ability to access and analyze remote imagery from multiple time periods is becoming easily available to non-technical users as well as to GIS specialists using publicly available tools built on the ArcGIS, Google Earth and Earth Engine platforms. In this workshop we will present case studies using these platforms to visualize and analyze changes in the landscape such as burn scars and tree loss from wildfires, surface water gain or loss from droughts and floods, and historic imagery useful for visualizing a whole host of environmental changes over time. We will discuss how to use our own data on these platforms, as well as workflows to import and export data to multiple tools including the KSU Brownfields Inventory Tool (BiT). Using the EPA EJScreen and EnviroAtlas, participants will further explore case studies of how climate change impacts will affect the work of Brownfields and other tribal environmental programs. Hands-on activities will be provided in an on-demand format and will be used in the workshop session. Participants will need a laptop computer for the extensive hands-on activities, and it is recommended, although not required, that participants arrange to use Google Earth Pro (desktop download) and access a Google account on their computers.

Introduce Yourself
Introduce Yourself
Let's begin by getting to know each other. We will work in groups on Jamboards, which are like a virtual whiteboard. The links below will take you to your group's Jamboard. The slides give you pointers on how to use them.
There are 5 pages with prompts; you will tell us something about yourself, your community, the place you are interested in and the story you want to tell.
Your Jamboards will be public, so please do not put any private information on them; they are collaborative, and we ask that you respect each other's work. That said, please interact and respond to what others in your group share; we want to get to know each other and have a little fun while we work.
Don't worry if you are using a work computer that blocks Google Accounts, you will still be able to add material to the Jamboard; but if you have a Google Account you will also be able to upload photos.
Group A.pdfUse this slide presentation to learn the basics of using Jamboards.

Activity #1 Make a folder
Activity #1 Make a folder
We will develop a workflow that allows us to keep track of the many different files and products (websites, maps, documents, forms, image files, SHP and KML files, etc.) that we will use to create our case studies.
Note: If you cannot access a Google Account because you are using a work computer, you can create a folder either on your computer or on whatever online platform you normally use (for example, Dropbox, MicroSoft OneDrive, etc.). The important point is that we begin by creating a place to store all of our work; preferably this will be shareable online with colleagues. If you can't create your own folder, take a look at the folder for the case study click here and use that to follow along.
The slides below give you a step-by-step set of instructions for this activity.
You will use this folder throughout our workshop to store your files. If you are using Google Drive you will be able to create maps, websites, forms, spreadsheets, etc. and store them all in your folder. This creates a single location for your collaborators to find all of the materials used to develop your project. You can easily add or remove collaborators from the folder and it will change the permissions on everything in the folder; by simplifying project management you can control who has access and who manages the project over time.
If you do not have a Google Account, you can create a personal account here . You can also use a work account if you have one.
Go to Google Drive and sign in (choose Go to Drive for personal accounts)
Create a folder; name your folder; set the sharing permissions
Create a Document to record website links, etc. used in developing your project to help collaborators retrace your steps
Activity #2 Make a website
Activity #2 Make a website
In order to share our work and engage our community, we will create a simple website using Google Sites. This is the easiest way to quickly share rich media content such as slide presentations, maps, images, and videos. One of the important things that you can do by sharing your content on a website (as opposed to sharing a folder or individual items) is that you can provide a context for the materials which allows you to develop a story that is easier to understand than an assortment of files that are not presented in relation to each other.
You can create a Google Site in your project folder in Google Drive.
Go to your Google Drive project folder
Click New>More>Google Sites
Give your Google Site a name
Set the sharing permissions
Choose a theme
Add your logo or an image to the header
Write a paragraph that describes your project
Activity #3 Make a form
Activity #3 Make a form
Oftentimes we want to find out information from our communities; for example, we may want to set up a way to have community members tell us about properties they are concerned about. An easy way to do this is to make a Google Form in your project folder, connect it to a Google Sheet to collect responses, and embed the Form in your website. The Response Sheet can be imported into a Google My Maps for visualization.
Go to your Google Drive project folder
Click New>Google Forms
Give your Form a name
Choose a theme, add your logo or an image to the header
Choose a destination; use Sheet
Create a list of questions
Answer the questions in the Form below and click Submit at the bottom. You will see the responses in the Google Sheet. Do not enter any private information since this will be made public. We will then import the Response Google Sheet into the My Maps below.
Activity #4 Make a map
Activity #4 Make a map
We will find information about sites using a variety of free mapping platforms (the EPA EnviroMapper and Cleanups In My Community, the Brownfield Inventory Tool) and then import the map data into a Google My Maps. We can also import a Google Sheet connected to a Form to visualize the answers to a survey.
Google My Maps is a free mapping tool available in your Google Drive. It is an especially fast and easy way to create an interactive map that can be embedded in a website.
Go to your Google Drive project folder
Click New>More>Google My Maps
Give your map a name and description
Set sharing permissions
Choose a base map
Add Points, Lines and Polygons
Add a new layer and import a file
Use data exported from BiT if you have an account
Use data exported from EnviroMapper or Cleanups In My Community
Use the Response Sheet from our last activity click here
The Brownfield Inventory Tool (BiT) is a free comprehensive brownfield program management tool. You may enter detailed site data, upload documents and data, and generate and export a variety of reports, including a Property Profile Form. BiT users are asked to create a user name and password for privacy protection. BiT can also be used as a collaborative tool.
Once you have established an inventory of sites (brownfields, cultural sites, etc.) you can use the map within BiT to visualize your inventory, or you can export a spreadsheet or map file to use on other platforms such as Google My Maps, Google Earth, and the EnviroAtlas.
The EPA EnviroMapper, like the other EPA mapping tool, is built on an ArcGIS platform that pulls data from sources such as EPA ACRES, and all of the EPA mapping tools will pull data from the same sources (all of the Brownfields sites will be mapped from ACRES data, for example). This means that if there is a data layer you want to use, find the platform that most easily allows you to download the data in a user friendly format (EnviroMapper, Cleanups in Your Community, etc.). The best format for mapping your data using My Maps is a CSV file. A CSV file format is a universal spreadsheet format type that you can also open in Excel or Google Sheets. It has the advantage that when you open it as a spreadsheet you can edit and add to it using all of the tools available in Excel or Google Sheets (things like autofill and sort to help with quality control). Once you edit it you can import it into Google My Maps. You can also find mapping file formats such as SHP (used for ESRI ArcGIS and Google Earth Pro) and KML/KMZ (used for Google My Maps, Google Earth Pro and ESRI ArcGIS). The advantage of downloading a file in these formats is that you can use polygons and lines (shapes) as well as points. The disadvantage is that you can't open it as a spreadsheet and edit it without coding.
EPA Cleanups in My Community website
The Cleanups in My Community platform will let you create a map with many useful layers, but it cannot be downloaded and you must print it as a PDF file. CIMC will also download data, but you must do it from the Lists or Tables page, not from the mapping tool. The best format to use for downloading data is CSV format which is a universal file type and will work in My Maps as well as Excel.
The advantage of CIMC exports is that they give you a live link to the property information which will show up in the map markers on your My Maps.

Activity #5 Google Earth Pro Timeslider and Google Earth Web Timelapse
Activity #5 Google Earth Pro Timeslider and Google Earth Web Timelapse
One way to visualize change is to compare satellite and aerial imagery from different time periods. This is easy to do in Google Earth.
There are two versions of Google Earth, one is a desktop download (Google Earth Pro) and the other is online and is accessed through your browser (Google Earth Web). The Pro version has tools that allow you to do analyses, import GIS files and create complex maps, while the Web version is still in development and is more limited. For the purposes of our workshop today, we will use the Pro version where possible - but if your work laptop won't let you download the Pro version, you can still do some of the activities using Timelapse in Google Earth Web. Both versions are covered in the slide presentation below. If you use Google Earth Web be patient while it loads, it take quite a bit of bandwidth to run.
If you can download Google Earth Pro to your computer open it and do this activity
Search for your place of interest
Drop a pin, give it a name and write a description. Include the date. Set default view.
Open the timeslider and explore imagery from different dates; when you find something of interest, use points, lines and polygons to mark it. For each time period, drop a pin and give it a name then set default view.
In the left panel click on each pin and watch how the imagery changes. What can you learn from images from different dates?
Print the images as JPG or PNG files and upload them to your project folder in Google Drive and add it to your Google Site.
If you cannot download Google Earth Pro to your computer, open Google Earth Web in your browser (it works best in Chrome)
Search for your place of interest
Drop a pin, give it a name and write a description. Include the date. Set default view.
Go to Voyager and find Timelapse. You will need to search for your place of interest again with Timelapse open.
Stop and start Timelapse to find historic imagery that you are interested in.
Print the images as JPG or PNG files and upload them to your project folder in Google Drive and add it to your Google Site.
