中文摘要：

在油气勘探过程中，常需要进行野外踏勘以确定野外地表条件是否可行。随着计算机、遥感等技术的发展．在室内计算机上通过Google Earth即可实现野外地表备件的查看，但存在坐标系统的不一致，需要进行坐标转换，另外．盆地规模的勘探制图往往又涉及坐标的投影跨带问题，需要对邻带坐标进行统一投影。

英文摘要：

Exploration for oil and gas often needs to carry out field reconnaissance to determine the feasibility of the field surface conditions.With the development of computer,remote sensing technology,we can use a computer indoor to realize the field surface conditions through Google Earth to view,but there are some consistencies in the coordinate system.They need coordinate transformation.In addition,mapping of the whole basin-scale exploration often involves projection coordinates cross-belt problem,the need for a unified coordinate with adjacent projection.
