透明座标板由于外业人员打座标网手续繁琐，时间花费很长，而且结果亦不见得能保证精确，因此根据上述情况改用照相胶板制成的“透明座标板”，这样节省人力，节约时间，又保证了精度，比原来提高了一倍多的效率。它的用法是先以透明板在图纸上透好座标网，再在座标网上展绘图廓点及测绘控制点。 Transparent coordinate plate as a result of outside staff to play coordinate network cumbersome procedures, the time it takes a long time, and the result is not necessarily accurate, so according to the above situation to use photographic plastic plate made of “transparent coordinate plate”, thus saving Manpower, save time, but also ensure the accuracy, more than doubled the efficiency of the original. Its usage is to first transparent plate in the drawings on a good coordinate network, and then in the coordinate network exhibition plot points and mapping control points.
