  • Niche and Thematic Strategic Planning to Increase International Tourism
    International Journal of Business, Humanities and Technology Vol. 4 No. 2; March 2014 Niche and Thematic Strategic Planning to Increase International Tourism Bob Lee, PhD Associate Professor Tourism, Leisure and Event Planning School of Human Movement, Sports and Leisure Studies Bowling Green State University Bowling Green, Ohio USA Yu Liu, PhD Qiuju Wang, PhD Associate Professor Department of Economy and Tourism, Tourism College Beijing Union University Beijing China David Groves, DEd Professor Emeritus Tourism, Leisure and Event Planning School of Human Movement, Sports and Leisure Studies Bowling Green State University Bowling, Ohio USA Abstract The focus of this study was to review the tourism planning procedures of Hangzhou. Hangzhou is a city in China that has the largest domestic tourism base. Tourism professional primarily used a mass marketing approach for planning which was effective, but the city is exploring new methods to increase its international tourism. What is being proposed is the development of niche marketing based upon thematic planning. Mass marketing is from top to bottom and the proposed method is from bottom to top with the active involvement of tourism professionals. Both methods are necessary for the development a plan that has continuity. Key Words: strategic planning, thematic development, niche planning, international tourism, and planning continuity 1.0 Purpose The purpose of this study was to review the planning process used in Hangzhou, China. Hangzhou is an excellent case study because it has an urban and rural environment, excellent tourism perspective, and a progressive and aggressive tourism development philosophy. This is a case study to illustrate how niche marketing methods can be used as an input for the planning processes.

However, effective cooperation between architects and the survey team of experts is necessary in order to get the best out of this geodata acquisition technology. In this article, the authors first provide an overview of equipment based on the size of the site and the surveying aim, and subsequently give four examples of how terrestrial laser scanning can benefit the restoration of damaged historical buildings.

In recent times, another type of building has been added to this list: industrial heritage. Today, terrestrial laser scanning (TLS) is one of the most advanced measurement techniques for the 3D documentation of such sites. The value of TLS for capturing damaged or decayed historic buildings is that scans can be used to accurately measure and virtually reposition partially or fully destroyed statues, ornaments and other elements. This provides insight into the damaged objects and into which elements can be restored and which will have to be completely remade.
