主機簡介：TMJ-2009面積(ji)測量(liang)儀(yi)也(ye)稱(cheng)為(wei)GPS面積(ji)測量(liang)儀(yi)、、收割機面(mian)積測(ce)量儀，此儀器集成了高精度的(de)GPS定位系(xi)統、精確的(de)面(mian)積計算(suan)方法和(he)智能化的(de)掌(zhang)上電(dian)腦(nao)系(xi)統，能實(shi)現不規則面(mian)積的(de)實(shi)時(shi)測(ce)試、動態圖形顯(xian)示和(he)數(shu)據智能化處理和(he)儲(chu)存。
選定(ding)面積丈量(liang)形(xing)(xing)(xing)式，然(ran)后(hou)按(an)(an)順(shun)時針(或(huo)逆時針)方(fang)向分別在四邊形(xing)(xing)(xing)極點順(shun)次豎(shu)立反射鏡并進行觀(guan)測(ce)(ce)。當觀(guan)測(ce)(ce)到第三點時邊能顯(xian)現(xian)其(qi)三點圍成的(de)(de)面積，假(jia)如要測(ce)(ce)小班是雜(za)亂的(de)(de)多(duo)(duo)邊形(xing)(xing)(xing)，一定(ding)要順(shun)次按(an)(an)次序測(ce)(ce)完各極點，即會剎(cha)那間顯(xian)現(xian)出(chu)多(duo)(duo)邊形(xing)(xing)(xing)的(de)(de)實踐面積。對有弧線的(de)(de)多(duo)(duo)邊形(xing)(xing)(xing)要在圓弧部位可盡(jin)量(liang)多(duo)(duo)設立鏡點。
假如圖形鴻溝彼此交叉面(mian)(mian)(mian)(mian)積(ji)(ji)(ji)則不能正(zheng)確核算(suan)(suan)。故在(zai)(zai)丈(zhang)量過程(cheng)(cheng)(cheng)中(zhong)(zhong)(zhong)有必要(yao)(yao)依照(zhao)次(ci)序來丈(zhang)量一切(qie)極點。因為林(lin)(lin)(lin)地(di)小(xiao)班(ban)形狀(zhuang)雜(za)亂(luan)多樣,在(zai)(zai)運用(yong)全(quan)站(zhan)儀面(mian)(mian)(mian)(mian)積(ji)(ji)(ji)丈(zhang)量過程(cheng)(cheng)(cheng)中(zhong)(zhong)(zhong)，可根(gen)(gen)據(ju)其不一樣形狀(zhuang)采(cai)取(qu)不一樣的(de)設站(zhan)點。全(quan)站(zhan)儀安頓在(zai)(zai)要(yao)(yao)測(ce)林(lin)(lin)(lin)地(di)小(xiao)班(ban)內或外均可。但要(yao)(yao)一次(ci)能看到(dao)要(yao)(yao)測(ce)林(lin)(lin)(lin)地(di)小(xiao)班(ban)的(de)一切(qie)極點。農機(ji)作業(ye)面(mian)(mian)(mian)(mian)積(ji)(ji)(ji)測(ce)量儀面(mian)(mian)(mian)(mian)積(ji)(ji)(ji)較(jiao)大時，應分塊段施(shi)測(ce)。在(zai)(zai)能看到(dao)方針的(de)前(qian)提下盡可能使(shi)鏡(jing)頭放(fang)低(di)來下降鏡(jing)頭偏(pian)疼差錯。最佳選擇(ze)地(di)勢較(jiao)高部(bu)全(quan)站(zhan)儀具有斜距主動改正(zheng)功用(yong)，在(zai)(zai)林(lin)(lin)(lin)地(di)小(xiao)班(ban)面(mian)(mian)(mian)(mian)積(ji)(ji)(ji)丈(zhang)量中(zhong)(zhong)(zhong)不受(shou)地(di)勢凹凸(tu)的(de)影(ying)響。若需(xu)求核算(suan)(suan)傾(qing)斜面(mian)(mian)(mian)(mian)積(ji)(ji)(ji)時可根(gen)(gen)據(ju)已知(zhi)斜角α和水(shui)平面(mian)(mian)(mian)(mian)積(ji)(ji)(ji).在(zai)(zai)林(lin)(lin)(lin)業(ye)六大工程(cheng)(cheng)(cheng)施(shi)行過程(cheng)(cheng)(cheng)中(zhong)(zhong)(zhong)，各(ge)級主管部(bu)門需(xu)要(yao)(yao)對(dui)工程(cheng)(cheng)(cheng)質(zhi)量進(jin)行監督和檢(jian)(jian)驗(yan)，因為涉(she)及到(dao)國家對(dui)工程(cheng)(cheng)(cheng)項(xiang)目(mu)的(de)資(zi)金補助，農機(ji)作業(ye)面(mian)(mian)(mian)(mian)積(ji)(ji)(ji)測(ce)量儀工程(cheng)(cheng)(cheng)項(xiang)目(mu)面(mian)(mian)(mian)(mian)積(ji)(ji)(ji)合格與否便是(shi)(shi)質(zhi)量檢(jian)(jian)驗(yan)重要(yao)(yao)一項(xiang)。這些年在(zai)(zai)退(tui)耕還林(lin)(lin)(lin)工程(cheng)(cheng)(cheng)和國家公益(yi)林(lin)(lin)(lin)、省級公益(yi)林(lin)(lin)(lin)界定效果(guo)等項(xiang)目(mu)的(de)復(fu)查檢(jian)(jian)驗(yan)中(zhong)(zhong)(zhong)。慣例運用(yong)的(de)面(mian)(mian)(mian)(mian)積(ji)(ji)(ji)復(fu)查方法是(shi)(shi)：一是(shi)(shi)對(dui)于面(mian)(mian)(mian)(mian)積(ji)(ji)(ji)較(jiao)小(xiao)的(de)林(lin)(lin)(lin)地(di)小(xiao)班(ban)拉尺實測(ce)，面(mian)(mian)(mian)(mian)對(dui)不規則小(xiao)班(ban)想丈(zhang)量準確有難度(du)；二是(shi)(shi)對(dui)面(mian)(mian)(mian)(mian)積(ji)(ji)(ji)相對(dui)較(jiao)大的(de)，在(zai)(zai)地(di)勢圖現(xian)場(chang)勾繪后進(jin)行地(di)勢圖上(shang)量算(suan)(suan)。
