IE GSI GSNI Magnetic First Vertical Derivative 50m Ireland (ROI/NI) ITM GRID WMS

From a plane, this survey measures the magnetic strength of rocks below. This allows us to map different types of rocks, even in areas were rocks are covered by soil. The findings tell us about the rocks in the ground. This is useful if you want to drill for water or to help find minerals (materials taken from the ground used for things we need from mobile phones to the stones used to build roads and houses).

本次航空勘测通过机载手段测定下方岩层的磁强度，借此可绘制不同类型岩石的分布图谱，即便在岩石被土层覆盖的区域亦能完成此类测绘。勘测结果可揭示地下岩石的相关特征与分布信息，该技术在钻井取水或探寻矿物时具备重要实用价值——矿物指从地下开采的物料，其应用范围涵盖手机制造、道路与房屋修筑所用石材等各类生产生活所需的领域。
