With the NTS layer turned off and the Georgetown_modified layer turned on, the Kent Square Polygon and Kent St. line are visible. \" width=\"1032\" height=\"791\" class=\"size-full wp-image-951\" \/> Figure 4.41[\/caption]\r\n\r\nWe can see how the town has changed very little between 1880 and 1991 and how this lack of change is indicative of the town\u2019s stagnation.\r\n\r\nThe two churches are still in their same locations. Often, when a town\u2019s population expands, more churches are built to accommodate the newcomers. In Georgetown, it seems that the demand for churches remained the same between 1880 and 1991, which perhaps suggests a stagnation. The only new feature that we can see between 1880 and 1991 is the King\u2019s Playhouse.\r\n\r\nBetween 1880 and 1991, there was no additional road built with which to enter Georgetown. Kent Street has remained the only way into the town. This shows that Georgetown's settlement and commercial activity has only ever required one main entrance into the town. By contrast, there are many roads by which to enter the Island\u2019s major towns, Summerside and Charlottetown.\r\n\r\nThere was very little change to Kent Square between 1880 and 1991. This shows that, despite over 100 years passing, the heart of the town remained largely the same between 1880 and 1991. That settlers\u2019 homes and merchants\u2019 buildings never really encroached on the square over a period of 100 years shows that Georgetown\u2019s development had stagnated.\r\n<h2>Change as a Sign of Decline<\/h2>\r\nWe will now digitize features that existed in Georgetown in 1880 but had disappeared by 1991. This loss of features will perhaps reveal more aspects of Georgetown\u2019s decline.\r\n\r\nTo start with, we will digitize Georgetown's railway station, its customs house, and shipbuilder Benjamin Davies\u2019 shipyard as points. We will also digitize Georgetown\u2019s ferry wharf as a line and its railway wharf as a polygon.\r\n\r\nThe railway came to Georgetown in 1872, and it augmented the town\u2019s status as a port of trade. Passengers and goods were shipped into the port, from which the railway could take them inland. To facilitate this process, Georgetown\u2019s railway station and railway wharf were built.\r\n\r\nThat Georgetown had a customs house further shows that the town was a key port of entry in 1880.\r\n\r\nBenjamin Davies, a significant Island shipbuilder of the late nineteenth century, presumably built ships in Georgetown as part of Georgetown\u2019s booming shipbuilding industry in the late nineteenth century.\r\n\r\nThe ferry connection between Georgetown and Pictou was a key driver of Georgetown\u2019s prosperity in the nineteenth century, before it was replaced by the ferry link between Borden-Carleton and Cape Tormentine in the twentieth century. The ferry wharf for which we will create vector data was the place at which the ferry docked in Georgetown.\r\n\r\nAll of the above features were part of Georgetown in 1880 and were keys to its prosperity. So, their disappearance by 1991 is indicative of the town's decline.\r\n<h1>Creating Vectors: Points, Lines, and Polygons<\/h1>\r\n<h2>An Important Note about Scale<\/h2>\r\nUnlike the 1991 topographic map, the Georgetown map from Meacham\u2019s Atlas (1880) is an urban map at a large scale. So, we do not have to consult the basemap to verify the locations of our points, lines, and polygons on the Georgetown map. Since we used the basemap and made sure that we mapped the vector data on the NTS map at a larger scale, we are able to make accurate comparisons between the 1880 and 1991 maps.\r\n<h2>Points<\/h2>\r\n<h3>Creating a New Shapefile<\/h3>\r\nTo create our vector data, we will first create a new shapefile layer.

Often, when a town\u2019s population expands, more churches are built to accommodate the newcomers. In Georgetown, it seems that the demand for churches remained the same between 1880 and 1991, which perhaps suggests a stagnation. The only new feature that we can see between 1880 and 1991 is the King\u2019s Playhouse.<\/p>\n<p>Between 1880 and 1991, there was no additional road built with which to enter Georgetown. Kent Street has remained the only way into the town. This shows that Georgetown&#8217;s settlement and commercial activity has only ever required one main entrance into the town. By contrast, there are many roads by which to enter the Island\u2019s major towns, Summerside and Charlottetown.<\/p>\n<p>There was very little change to Kent Square between 1880 and 1991. This shows that, despite over 100 years passing, the heart of the town remained largely the same between 1880 and 1991. That settlers\u2019 homes and merchants\u2019 buildings never really encroached on the square over a period of 100 years shows that Georgetown\u2019s development had stagnated.<\/p>\n<h2>Change as a Sign of Decline<\/h2>\n<p>We will now digitize features that existed in Georgetown in 1880 but had disappeared by 1991. This loss of features will perhaps reveal more aspects of Georgetown\u2019s decline.<\/p>\n<p>To start with, we will digitize Georgetown&#8217;s railway station, its customs house, and shipbuilder Benjamin Davies\u2019 shipyard as points. We will also digitize Georgetown\u2019s ferry wharf as a line and its railway wharf as a polygon.<\/p>\n<p>The railway came to Georgetown in 1872, and it augmented the town\u2019s status as a port of trade. Passengers and goods were shipped into the port, from which the railway could take them inland. To facilitate this process, Georgetown\u2019s railway station and railway wharf were built.<\/p>\n<p>That Georgetown had a customs house further shows that the town was a key port of entry in 1880.<\/p>\n<p>Benjamin Davies, a significant Island shipbuilder of the late nineteenth century, presumably built ships in Georgetown as part of Georgetown\u2019s booming shipbuilding industry in the late nineteenth century.<\/p>\n<p>The ferry connection between Georgetown and Pictou was a key driver of Georgetown\u2019s prosperity in the nineteenth century, before it was replaced by the ferry link between Borden-Carleton and Cape Tormentine in the twentieth century. The ferry wharf for which we will create vector data was the place at which the ferry docked in Georgetown.<\/p>\n<p>All of the above features were part of Georgetown in 1880 and were keys to its prosperity. So, their disappearance by 1991 is indicative of the town&#8217;s decline.<\/p>\n<h1>Creating Vectors: Points, Lines, and Polygons<\/h1>\n<h2>An Important Note about Scale<\/h2>\n<p>Unlike the 1991 topographic map, the Georgetown map from Meacham\u2019s Atlas (1880) is an urban map at a large scale. So, we do not have to consult the basemap to verify the locations of our points, lines, and polygons on the Georgetown map. Since we used the basemap and made sure that we mapped the vector data on the NTS map at a larger scale, we are able to make accurate comparisons between the 1880 and 1991 maps.<\/p>\n<h2>Points<\/h2>\n<h3>Creating a New Shapefile<\/h3>\n<p>To create our vector data, we will first create a new shapefile layer.
