CASS应用体验

  CASS是在(zai)绘(hui)图软件(jian)AOTCAD基础上开发的(de)(de)测量专用(yong)绘(hui)图软件(jian),增加了许多的(de)(de)专用(yong)工具和符(fu)号,为数字化测量带来了极(ji)大的(de)(de)方便。现将(jiang)CASS在(zai)应(ying)(ying)用(yong)中(zhong)应(ying)(ying)注意的(de)(de)事项及一些(xie)CASS应(ying)(ying)用(yong)经验阐(chan)述如下:

  1. 数(shu)据(ju)(ju)通(tong)(tong)(tong)讯(xun)(xun):外业使用(yong)带记录模块的全站仪进行外业测量记录,然后(hou)全站仪与微机利用(yong)CASS通(tong)(tong)(tong)讯(xun)(xun)软件进行通(tong)(tong)(tong)讯(xun)(xun),在通(tong)(tong)(tong)讯(xun)(xun)过程中,通(tong)(tong)(tong)讯(xun)(xun)参数(shu)一定要一制。最常用(yong)参数(shu)是(shi):协议(yi)ACK/NAK,通(tong)(tong)(tong)讯(xun)(xun)口COM1,波特率(lv)9600,数(shu)据(ju)(ju)位8,停止(zhi)位1,检效无(wu)。一般(ban)只通(tong)(tong)(tong)讯(xun)(xun)坐(zuo)标(biao)数(shu)据(ju)(ju),有(you)(you)时(shi)也通(tong)(tong)(tong)讯(xun)(xun)测量数(shu)据(ju)(ju)。数(shu)据(ju)(ju)通(tong)(tong)(tong)讯(xun)(xun)完(wan)毕(bi)后(hou)一定要检查有(you)(you)没(mei)有(you)(you)坏(huai)数(shu)据(ju)(ju),如(ru)果有(you)(you)就把坏(huai)数(shu)据(ju)(ju)删掉,否则(ze)就无(wu)法(fa)进行CASS坐(zuo)标(biao)转(zhuan)换(huan)(huan),然后(hou)把通(tong)(tong)(tong)讯(xun)(xun)数(shu)据(ju)(ju)转(zhuan)换(huan)(huan)成CASS坐(zuo)标(biao),起一个文件名将其保存。

  2.展(zhan)点(dian)(dian)(dian):打开CASS,在(zai)标题栏中(zhong)点(dian)(dian)(dian)击(ji)绘图处理,在(zai)其(qi)子(zi)目录中(zhong)点(dian)(dian)(dian)击(ji)展(zhan)高(gao)程点(dian)(dian)(dian),找(zhao)到(dao)CASS坐(zuo)标文件展(zhan)点(dian)(dian)(dian)即可。但展(zhan)上(shang)(shang)去的为测(ce)(ce)点(dian)(dian)(dian)点(dian)(dian)(dian)位(wei)和高(gao)程。用同种(zhong)方法(fa),在(zai)其(qi)子(zi)目录中(zhong)找(zhao)到(dao)展(zhan)外(wai)业测(ce)(ce)点(dian)(dian)(dian)点(dian)(dian)(dian)号(hao),把点(dian)(dian)(dian)号(hao)展(zhan)上(shang)(shang)。点(dian)(dian)(dian)号(hao),点(dian)(dian)(dian)位(wei),高(gao)程CASS默认为红色,为了(le)更醒目,可以把高(gao)程点(dian)(dian)(dian)或(huo)者(zhe)点(dian)(dian)(dian)号(hao)改(gai)变(bian)一下颜色,方法(fa)如(ru)下:点(dian)(dian)(dian)击(ji)图层管理,找(zhao)到(dao)测(ce)(ce)点(dian)(dian)(dian)号(hao)或(huo)者(zhe)高(gao)程点(dian)(dian)(dian)图层,改(gai)变(bian)其(qi)颜色即可。

  3. 连线(xian):即(ji)根(gen)据(ju)外业(ye)草图用CASS工具和符号把相(xiang)连的(de)点位(wei)连接(jie)起来,把测区地物地形如实(shi)的(de)反映出(chu)来。在连线(xian)过(guo)程中应当(dang)注(zhu)意陡(dou)坎连接(jie),陡(dou)坎连接(jie)后拟合时示坡线(xian)经常两边跑,为了解决这个(ge)问题有(you)一个(ge)比较好的(de)解决方法,即(ji)在连接(jie)陡(dou)坎时多点几个(ge)节点,特别是在坎拐弯(wan)和坎角,这样就能很(hen)好的(de)控制示坡线(xian)的(de)方向(xiang)。

  4.勾绘等(deng)(deng)高(gao)(gao)(gao)线(xian)(xian)(xian)(xian):勾绘等(deng)(deng)高(gao)(gao)(gao)线(xian)(xian)(xian)(xian)有(you)两种方(fang)(fang)法(fa):1.CASS依据测点自动生成,在(zai)(zai)山(shan)区地貌不(bu)是十分复杂,地物不(bu)多的(de)(de)情况下(xia)比(bi)较实用(yong),但是生成等(deng)(deng)高(gao)(gao)(gao)线(xian)(xian)(xian)(xian)后图形文件变(bian)的(de)(de)比(bi)较大,为后期处理带来(lai)许(xu)多不(bu)便,在(zai)(zai)微机配置不(bu)高(gao)(gao)(gao)的(de)(de)情况下(xia)一般不(bu)要用(yong)。2. 手工(gong)绘制(zhi)(zhi)等(deng)(deng)高(gao)(gao)(gao)线(xian)(xian)(xian)(xian):等(deng)(deng)高(gao)(gao)(gao)线(xian)(xian)(xian)(xian)在(zai)(zai)绘制(zhi)(zhi)时会自动拟合(he),线(xian)(xian)(xian)(xian)体有(you)很多节点,在(zai)(zai)修改时非常(chang)麻(ma)烦。现有(you)一个比(bi)较好的(de)(de)方(fang)(fang)法(fa),使等(deng)(deng)高(gao)(gao)(gao)线(xian)(xian)(xian)(xian)修改变(bian)的(de)(de)非常(chang)简单(dan)。方(fang)(fang)法(fa)如下(xia):在(zai)(zai)绘制(zhi)(zhi)等(deng)(deng)高(gao)(gao)(gao)线(xian)(xian)(xian)(xian)时不(bu)要直接(jie)使用(yong)绘制(zhi)(zhi)等(deng)(deng)高(gao)(gao)(gao)线(xian)(xian)(xian)(xian)工(gong)具,而(er)使用(yong)复合(he)线(xian)(xian)(xian)(xian)工(gong)具来(lai)绘制(zhi)(zhi)等(deng)(deng)高(gao)(gao)(gao)线(xian)(xian)(xian)(xian),因为复合(he)线(xian)(xian)(xian)(xian)非常(chang)容易拉动修改。在(zai)(zai)等(deng)(deng)高(gao)(gao)(gao)线(xian)(xian)(xian)(xian)绘制(zhi)(zhi)完后可(ke)以(yi)批量拟合(he)复合(he)线(xian)(xian)(xian)(xian),然后把拟合(he)后的(de)(de)复合(he)线(xian)(xian)(xian)(xian)加注等(deng)(deng)高(gao)(gao)(gao)线(xian)(xian)(xian)(xian)属性即可(ke)。这样画出的(de)(de)等(deng)(deng)高(gao)(gao)(gao)线(xian)(xian)(xian)(xian)套合(he)的(de)(de)非常(chang)好,非常(chang)漂亮。

  5. 文件保存: CASS在使用中有文件自动保存功能,但是在CASS软件使用不当,出现致命错误时文件容易丢失,所以要对文件时时做备份保存,即另存文件,建议大约每半小时做一次
