Extract the files to C:\EsriPress on a PC or to EsriPress under your home directory on a Mac.This tutorial works for both PCs and Macs, though the lab data directories differ on them. To simplify the tutorial instructions, the following tutorial mentions the data directory on the PC only.

      2 In Microsoft Excel, navigate to C:\EsriPress\GTKWebGIS\Chapter1\Locations .csv, and study its data format.This file has the main POIs in the City of Redlands. You will examine the sample data to familiarize yourself with the required fields. The first row of your spreadsheet provides the header. Below that, each row contains one tour point. For each point, the Story Map Tour template expects the following fields:Name: A short name identifying the point.Caption: A description of the point. Keep it short (less than 350 characters is recommended). The caption can include HTML tags to format the text or provide hyperlinks.Icon_color (optional): The color of each point. The valid values—R, G, B, and P—indicate red, green, blue, and purple, respectively.Geographic Location: You can describe geographic location by specifying longitude and latitude as Long and Lat (in decimal degrees), a single Address field containing a complete street address, or multiple fields (such as Address, City, State, and ZIP).

The recommended image size is 1000 × 750 pixels, but other sizes will also work.For videos: The template does not include a generic video player. Instead, you will use the URL that a video hosting service, such as YouTube, provides for embedding videos via a link. You will append #isVideo to the end of the URL (for example, http://www.youtube .com/embed/RM0eMdrPhEA#isVideo). For YouTube videos, you will right-click the video being played, click Copy Embed Code, paste the code into Notepad, find the URL in the code, and append #isVideo to the end of the URL.To use photos or videos on your computer, you must first upload them to some form of online storage, such as Flickr, YouTube, or your own web server.If you have not yet collected your own images and videos, you can search for media through search engines and then copy their URLs. For images: Right-click an image. Select Copy Image Location in Firefox or Copy Image URL in Chrome. For Internet Explorer, select Properties and then copy the image address URL.Thumb_URL: The full web address of the thumbnail image (starting with http://, https://, or //). Images can fit to scale, but the recommended image size is 200 × 133 pixels.
