Building Engineering Mapping Method Based on GIS Digital Technology

传统建筑工程测绘方法测量结果通常与实际结果存在误差,降低了测绘精准度。文中研究基于GIS数字技术的建筑工程测绘方法,确定测绘作业流程以及空间信息库,利用GIS数字技术的建筑成像计算方法,生成测绘成果图及信息可视化,提出一种全新的测绘方法。实验结果表明,基于GIS数字技术的测绘方法使用后,当测试次数达到500次时,测绘过程中的鲁棒性可以维持在75%~90%之间,并且平均精准度可以达到91.37%,证明设计方法在应用过程中具有较好的测绘精度,具有一定的实用性。

Due to the error between the measurement results and the actual results of the traditional construction engineering surveying and mapping methods, the accuracy of surveying and mapping is reduced, and the construction engineering surveying and mapping method based on GIS digital technology is studied. Determine the surveying and mapping operation process and spatial information database, use the building imaging calculation method of GIS digital technology togenerate surveying and mapping result map and information visualization,and put forward a new surveying and mapping method. The experimental results show that when the mapping method based on GIS digital technology works, the robustness can be maintained between 75% and 90% during the mapping process reaches 500 times, and the average accuracy can reach 91.37%, which proves that the design method has good mapping accuracy and certainpracticability in the application process.
