Application of SharpMap open source mapping library in fisheries

SharpMap is one of the Open Source GIS Projects. It is an easy to use mapping library for use in web and desktop applications. Because the commercial GIS software has a large scale and costs are too high, so the range of applications is limited in small-scale secondary development. While the SharpMap is a small, open source, good map rendering library. It is very suitable for small-scale Software Design and development. In this paper, commands and tools are as the smallest functional units. The system functions are refined a few commands or tools. These minimum features are developed through programming. Finally the various commands and tools are integrated together to form a software. It is obtained satisfactory results in the application of fisheries.
