As we already know, that story maps allow individuals to create an effective narrative or a presentation based on a specific analysis of a particular topic. ArcGIS or also know as ready to use maps promotes a live atlas of the world with the addition of layers and many more features. ArcGIS online includes a wide range of creative maps and layers from weather and global warming transformations to historical war sites to pin pointed bomb droppings. The purpose of story mapping and ArcGIS online is to offer a collaborative environment that allows individuals to share maps, layers and scenes of quantitative and qualitative data.

For the purpose of this assignment I decided to analyze the historic Welland Canal project offered by ArcGIS online. To begin the Welland Canal expands a length of 43 kilometres, which was designed by Hiram Tibbetts with the purpose of connecting Lake Ontario and Lake Erie with a series of locks and man-made canals. The purpose of this map is to display the design of the Welland Canal from an arial view while incorporating multiple layers of information. When first observing the story map it is quick to notice the simplicity of reading the map due to the organization of the scales and legend. In this situation the scale of the map or range is considered to be from the start of the canal (North of St.Davids Road) to the end of the canal that finishes in Lake Ontario. (South of Lakeshore West). Secondly it is also quick to notice that there are two separate routes pin pointed on the map, this is due to the reconstruction of the canal over time. Therefore this digital archive of the Welland Canal is effective and creditable due to the evidence of showing the current active canal route and comparing it to the old Welland Canal route. The site also incorporates more simplicity by making it easy to remove layers and to add layers by a drop menu to further accommodate what information and statistics individuals want to be shown. Furthermore to personalize your viewing preferences the digital archive also offers a base map gallery which advertises multiple different viewpoints of the map such as a light grey canvas, dark grey canvas, or a open street perspective.

The digital archive of the Welland Canal is also effective by the significant legend that is offered to provide an easy guide to reading the map and its multiple layers. For instance the map includes the documentation of bridges, locks, remnants, bollards, and weirs. Each item that is listed in the legend is marked on the map and is also clickable which provides individuals with a small paragraph of information regarding that item on the map. The digital archive has also incorporated colour coding which allows viewers to have a better perspective of the Welland Canal and as well as the recent construction and innovations. One negative aspect that I found with this digital archive of the Welland Canal was the issue of marking the current Welland Canal route in the colour blue. Although the route is still easy to view the colour blue should on be used and considered when identifying large bodies of water on a map. In conclusion from studying story maps and digital archives from the past previous weeks, I am now able to effectively analyze a ArcGIS archive as well as design my own with incorporating layers and incorporate specific mapping strategies.
