EGIP geothermal map (MapServer)

The underground geothermal conditions can be presented, irrespective of the aquifers' position, with the appropriate geothermal maps. These maps represent the expected isoterms at a depths and are derived from Geothermal maps - Expected temperatures , which are made with data from 302 boreholes. It is made on the basis of measured temperatures in accessible boreholes throughout the country. However, since the temperature field depends on the geological structure in the depths and tectonic characteristics, the course of the isotherms is a result of many influences, such as thermal conductivity of rocks, permeability and fracturing of rocks, all of which are reflected in the measured temperatures in boreholes. The distribution of boreholes, which were useful for the measurement of temperature, is very uneven and different as regard the depths.借助适配的地热图，可展现地下地热状况，且不受含水层空间位置的限制。此类地图展示各深度处的预期等温线，其数据来源于以302个钻孔数据为基础编制的《地热图——预期温度》成果。该类地图基于全国范围内可获取钻孔的实测温度编制而成。然而，由于温度场受深部地质构造与构造特征影响，等温线的展布受多重因素共同作用，包括岩石热导率、岩石渗透性及岩石裂隙发育程度，上述因素均会在钻孔实测温度中得到体现。可用于温度测量的钻孔空间分布极不均匀，且在钻孔深度方面也存在显著差异。
