在Google Earth中顯示基站扇區(qū)詳解下面是效果圖,如果大家趕興趣,我會(huì)給出詳細(xì)步驟[attach]47069[/attach] kml文件是Google Earth的地標(biāo)文件,在Google Earth界面中隨便插入一個(gè)地標(biāo),然后選中-右鍵-復(fù)制,打開一個(gè)文本文件,粘貼.你就會(huì)看到原始文件,其實(shí)就是XML擴(kuò)展語言,很容易看懂.下面是一個(gè)例子:<?xml version="1.0" encoding="UTF-8"?><kml xmlns="http://earth.google.com/kml/2.1"><Document><name>KmlFile</name><StyleMap id="msn_ylw-pushpin"> <air><key>normal</key><styleUrl>#sn_ylw-pushpin</styleUrl> </Pair> <air><key>highlight</key><styleUrl>#sh_ylw-pushpin</styleUrl> </Pair></StyleMap><Style id="sh_ylw-pushpin"> <IconStyle><scale>1.3</scale><Icon><href></href></Icon><hotSpot x="20" y="2" xunits="pixels" yunits="pixels"/> </IconStyle></Style><Style id="sn_ylw-pushpin"> <IconStyle><scale>1.1</scale><Icon><href></href></Icon><hotSpot x="20" y="2" xunits="pixels" yunits="pixels"/> </IconStyle></Style><lacemark> <name>Untitled 地標(biāo)</name> <LookAt>[u][color=Red]<longitude>-96.49999999999993</longitude><latitude>40.50000000000001</latitude>[/color][/u]<altitude>0</altitude><range>25484000.00000001</range><tilt>2.862499213317163e-014</tilt><heading>7.802569820582511e-015</heading> </LookAt> <styleUrl>#msn_ylw-pushpin</styleUrl> <oint><coordinates>-96.49999999999994,40.50000000000001,0</coordinates> </Point></Placemark></Document></kml>這里面對(duì)我們有用的就是經(jīng)緯度語言格式,生成基站層就可以用它,怎樣才能批量生成基站層呢?目前已經(jīng)有很多軟件實(shí)現(xiàn),但我要告訴大家的是用 EXCEL 制作基站數(shù)據(jù).要下班了,今天先寫到這吧.2.第2步,制作EXCEL數(shù)據(jù)把上面XLM原文件集中到一行內(nèi),然后分批拷入EXCEL表格中,注意地標(biāo)名(基站名)單獨(dú)占一列,經(jīng)緯度各站一列,然后就可以把你的基站名稱和經(jīng)緯度拷入相應(yīng)列中,其它列數(shù)據(jù)用鼠標(biāo)拖動(dòng)復(fù)制即可,然后復(fù)制粘貼到txt文件中,另存為KML文件,用google earth打開后就是2樓的效果了.怎樣生成扇區(qū)呢,咱們下回書接著說.3.maoinfo中生成基站扇區(qū)我們可以用Mapinfo2Google軟件把maoinfo地圖轉(zhuǎn)成 Google Earth格式.但先要在maoinfo中生成基站扇區(qū),目前有很多mapinfo插件程序,這些程序都是通過maobasic 語言編寫的, 下面是生成扇區(qū)的關(guān)鍵程序, 希望給maobasic 語言愛好者一點(diǎn)幫助. if T_cellinfo.col5=360 thenupdate T_cellinfo set obj=createcircle(T_cellinfo.col3,T_cellinfo.col4,T_cellinfo.col6*1000) where rowid=rowelsepline_Spointx=T_cellinfo.col3+cos((360-T_cellinfo.col5-T_cellinfo.col7/2+90) * DEG_2_RAD)*T_cellinfo.col6*0.00001pline_Spointy=T_cellinfo.col4+sin((360-T_cellinfo.col5-T_cellinfo.col7/2+90) * DEG_2_RAD)*T_cellinfo.col6*0.00001pline1_Mpointx=T_cellinfo.col3pline1_Mpointy=T_cellinfo.col4pline2_Mpointx=T_cellinfo.col3+cos((360-T_cellinfo.col5+90) * DEG_2_RAD)*T_cellinfo.col6*0.00001pline2_Mpointy=T_cellinfo.col4+sin((360-T_cellinfo.col5+90) * DEG_2_RAD)*T_cellinfo.col6*0.00001pline_Epointx=T_cellinfo.col3+cos((360-T_cellinfo.col5+T_cellinfo.col7/2+90) * DEG_2_RAD)*T_cellinfo.col6*0.00001pline_Epointy=T_cellinfo.col4+sin((360-T_cellinfo.col5+T_cellinfo.col7/2+90) * DEG_2_RAD)*T_cellinfo.col6*0.00001 create pline into variable pline1_obj 3 (pline_Spointx,pline_Spointy)(pline1_Mpointx,pline1_Mpointy)(pline_Epointx,pline_Epointy) pen(1,2,black) create pline into variable pline2_obj 3 (pline_Spointx,pline_Spointy)(pline2_Mpointx,pline2_Mpointy)(pline_Epointx,pline_Epointy) pen(1,2,black) smooth cell_obj=converttoregion(combine(pline1_obj,pline2_obj)) update T_cellinfo set obj=cell_obj where rowid=rowend if
