摘要:

在自然重砂数据处理过程中,GIS是重要的常用工具之一,本文结合专业领域内数据处理需求和信息领域内的GIS二次开发技术,提出了一种高效、便捷的数据处理方法,通过在MapGIS软件平台下开发GeoTools软件工具,实现对自然重砂数据中的异常点数、平均值、最大值等特征参数进行批量计算及属性赋值,辅助完成自然重砂异常初步分级工作,收到了较为理想的效果。GeoTools软件工具在青海省和山西省的自然重砂资料处理的过程中进行了实际运用,取得了很好的效果,提高了工作效率及资料处理的精度和质量。GeoTools软件工具也可在MapGIS平台下对相关的资料进行处理和数据统计。

Abstract:

GIS is commonly used in processing heavy mineral data. This paper combined with professional data processing and GIS 2nd Development in information domain, presents an effective and fast data processing method that GeoTools developed in MapGIS can calculate in batch anomaly points, average, and maximum of heavy mineral anomaly, and help complete classification of anomalies. GeoTools had achieved good results in processing Qinghai and Shanxi’s heavy minerals data in rising efficiency and quality and accuracy, and can be processing data under MapGIS.
