在方才穿超出来的时候，严绍已经开端对这个期间的舆图跟沙盘一头雾水。讲事理，那些绘制非常粗陋的舆图，在他看来非常费事。只是当时别人微言轻，并且当时黄巾之乱也将近到末端了，也就没有需求跑出来显摆本身的设法。
严绍派出的这些探子，不但是需求刺探一些谍报，也需求停止测绘事情。
相较之下，严绍就不会如此了...
同时也按照这些质料，弄出了一个又一个的小沙盘出来，这也是乌桓之乱的经历经验。如果当时有充足多的沙盘，让严绍对全部北海乃至是全部青州都有充足的体味，那么在对于乌桓人的时候，便能够采纳更主动的姿势一一一一固然当时严绍已经干的非常不错了。
直到厥后，他成了北海太守以后，才开端了绘测事情。简朴些讲，就是派人在北海及青州境内，对阵势停止考查和研讨，最后清算出一个比较详细的舆图出来。
要说严绍穿越到这个期间所带来的窜改实在不算多，但是也绝对算不上少。起码在一些他自以为公道，并且不会对本身形成倒霉影响的东西上，他一贯是不吝于窜改的。
有了详细的数据，将来的战役当中也便能够更轻易把握主动权。
以是真的动起手来，真正用的还是舆图，只要在非常熟谙的一些地区又或者是一些关隘四周，才会有比较成熟的沙盘，嗯，这个成熟还是相对的...

没体例，这年初卫星确切多了，但是很多东西还是需求人用脚丫子去走，去测量的...
直到1811年，普鲁士国王菲特烈・威廉三世的文职军事参谋冯・莱斯维茨，用胶泥制作了一个精美的疆场模型，用色彩把门路、河道、村落和树林表示出来，用小瓷块代表军队和兵器，摆设在波茨坦皇宫里，用来停止军事游戏。厥后，莱斯维茨的儿子操纵沙盘、舆图表示地形地貌，以算时器表示军队和兵器的配置环境，遵循实战体例停止战略运营。这类“战役博弈”就是当代沙盘功课。
比如说沙盘...
比及了后代，常常有不法测绘职员被抓获的动静。
不过真正大范围的停止测绘事情，还是在严绍当上了青州牧今后。成了青州牧后，严绍清楚本身接下来的任务是甚么，派出了大量的探子到了邻近的各个州，这此中特别是以冀州、兖州和徐州为主。这也是最有能够与严绍发作抵触的三个州。
在严绍当上青州牧的这几年里，这些探子为严绍供应了大量的谍报，严绍州牧府的此中几个房间里，堆满了邻近州的沙盘。都是按照探子们传返来的谍报绘制的，这也让严绍在与敌手们比武时，更能
没有曼妙的身姿，没有靡靡的歌舞，有的只是十多个或是身穿甲胄或是衣冠楚楚的文武，站在一个庞大的由砂石构成的庞大沙盘前。
而严绍带来的窜改，就是后一者...
早在清朝，乃至是鸦片战役之前的乾隆期间，就已经有本国人在广州等互市地区停止奥妙的测绘事情，到了一战和二战时，更是如此。
探子和间谍实在没甚么辨别，凡人的思虑当中，间谍的事情凡是都和007有些近似，就算不是如许，起码也是高端大气上层次的那种，实际上间谍的事情涵盖面真的很广。不但有高端的007系列，也有其他的并不是那么很高端的事情，这此中就包含了之前提到的测绘。
当代沙拨弄起来比较费时，并且相较之下也没有比舆图强出太多来，每到一个处所，又都还需求考查阵势才气够，恰好当代的王朝对于本身的国度，很少停止绘测，所具有的舆图都是非常粗陋的那种，那里会有质料弄沙盘？
沙盘这个东西其实在当代就已经开端有了，但是这个期间的沙盘凡是都很粗糙。中国南朝宋范晔撰《后汉书・马援传》已有记录：汉建武八年（公元32年）光武帝挞伐天水、武都一带处所豪强隗嚣时，大将马援“聚米为山谷，指画情势”，使光武帝顿有“虏在吾目中矣”的感受，这就是最早的沙盘功课。
嗯嗯，不美意义，前面的必然尽快补上！！！
