The GPS Promark 3, koyamba

Ndatengapo maseŵera awa m'bokosi, mkati sabata imodzi tidzachita maphunziro kuti tiwone momwe zikuyendera. Pakadali pano, sindinawonepo makanema ndi zina mwazinthu zina.

Otsatira a Promark 3.

Mu mzere womwewo, kunalipo kale ndipo kunali omaliza:

• Mobile Mapper Pro, chidole chabwino chomwe chidapita ku US $ 1,500, ndikuti pambuyo pokonza pambuyo pake adakwaniritsa mwatsatanetsatane. Itha kukhala maziko komanso rover. Tsopano yatha; Zinali zokhumudwitsa kuti khadiyo idasinthidwa poyambira, mwina chifukwa cha kachilombo, mwina chifukwa cholakwika pambuyo pa kunyanyala kwa ogwira ntchito pakampaniyo.
• Mobile Mapper CXUwu ndi mtundu wabwino wa Pro, yokhala ndi tinyanga titha kugwiritsidwa ntchito ngati GPS ya geodetic. Adali ndi wachibale dzina lake CE, yemwe adathamanga pa Windows CE, ndipo kuchokera pazomwe ndidamva, CX iyi siyimva mutu wake.
• Mobile Mapper 6, uwu ndi mzere watsopano, Ndayankhula izi nthawi zingapo. Zambiri kapena zochepa ndizofanana Juno Trimble, ngakhale imadutsa mwatsatanetsatane. Sizingakhale zoyambira, zokhazokha zokhazokha ndipo munthawi yeniyeni ndiyolowera kuyendetsa bwino yolondola ya 3 mpaka 5 mita.

Kodi chatsopano ndi PM3

Izi zimabweretsa ntchito zofanana ndi Pro ndi CX, mosiyana ndi 6 yomwe imabweretsa Mapping Mapping, kamera, kampasi ndi makapu ambiri. Kwa iwo omwe amayesa Pro, ndi zophweka chifukwa njira yogwirira ntchito ndi yofanana, kuphweka masitepe ambiri mu menyu, yomwe yowonjezerapo makibodi ndi mawonekedwe ogwiritsira ntchito amachititsa kuti ikhale yopindulitsa. Zimathandiza kuti phwando la RTK likugwirizane, Sindikutsimikiza ngati ikuthandizira mapulogalamu ena, monga ArcPad, omwe MM6 angachite. Zoonadi, kuthekera kwa mapulogalamu amene mumabweretsa (Fast Survey) sichikufanana ndi Mapu Mapulogalamu, potsata ndondomeko, mawonetsedwe a malingaliro ndi zina zamutu.

Monga Pro, imatha kukhala yoyambira kapena yokhotakhota, yogulidwa awiriawiri, ndipo imabwera mu thumba la duffel lothandiza. Chilichonse chimakhala ndi tinyanga, munthawi yeniyeni imapeza mwatsatanetsatane (zomwe pro adachita posintha). Kusiya maziko amodzi kumatha kupatsa masentimita masentimita, komanso manambalawa angapangitse kuti MM6 ifike pamametric monga zikuwonetsedwera pamwambowu kale.

Pakati pazowonjezera pali chosinthira choyika pamiyendo itatu, china kuchilikiza pamtengo komanso lamba kuti chikonzeke padzanja; tepi yomwe ingatenge kutalika kwa antenna, adaputala yamitundu yosiyanasiyana yolumikizira USB / Serial. Mwazina, chingwe cha antenna, ma adapter osiyanasiyana amagetsi, khadi ya SD ndi chikwama chopanda madzi.

Batri ndi lithiamu, yokhala ndi maola ochulukirapo, kupitilira omwe adalipo kale omwe adagwiritsa ntchito AA; pogula awiriwa kubwera bala komwe kuli kothandiza kuziyika mumikhalidwe yofananira mukamagwira ntchito "yoyimilira ndikupita". Amabweretsa mapulogalamu a Mobile Mapper Office post-processing, mtundu wa 3.4 omwe kale amathandizira raster data, kulumikizana ndi Mapinfo data, shp, dxf ndi csv; Komanso kugwiritsa ntchito pulogalamu ina yotchedwa GNSS mayankho, yomwe imaphatikizapo kukonza mapulani a kafukufuku. Ntchito yomalizayi ili ndi mawonekedwe owoneka bwino kwambiri, okhala ndi zosankha ndikukoka, malipoti ndi chiwonetsero cha isometric.

Chimodzi mwazinthu zabwino kwambiri, DVD yokhala ndi makanema m'Chisipanishi, powonera mutha kupulumutsa kuwerenga kwambiri ndikumvetsetsa m'njira momwe imagwirira ntchito; ngakhale bukuli ndilothandiza kwambiri. Vidiyoyi ndi yabwino kuphunzitsira, kuphatikiza gawo lomwe limafotokoza momwe magulu am'mlengalenga amagwirira ntchito komanso zomwe zimakhudza phwando. Mulinso mitu:

• Kupereka kwa timu
• Zosintha zoyamba
• Chiyambi cha ntchito ya GPS
• Kodi mungatani kuti muthe kukweza
• Imani ndi kupita kukweza ndi zakuthupi
• Pulogalamu yafukufuku wamunda
• Pogwiritsa ntchito Mobile Mapper Office ndi Other Office Software
• Kugwira ndi kuyang'anira deta ya GIS

Mu mitengo, zimadalira wogulitsa m'deralo, choncho ndinayang'ana kumalo anga, Mobile Mapper Pro inkayenda kwa US $ 1,500, MM6 imayenda pansi pa 1,200 ndi Promark3 pafupi ndi $ 6,000. Osati zoyipa mukaganiza kuti kulondola kwa sentimita kungakwaniritsidwe, zopangidwa zina sizimapereka zida ngati izi pamtengo uwu.

Ngati ndiyenera kuyerekeza ndi kompyuta ina, zikhoza kunenedwa kuti ziri ngati Sakanizani GeoXH, ngakhale kuti sizili chimodzimodzi.

Chotsatira ndi chiyani

Tiyeni tichite maphunziro sabata ino ndi anyamata ochokera ku station yonse ndi anzawo omwe akufuna kuphunzira zaulere. Ndife okonda kuyesa zina monga:

• Accuracies womvera chofanana ndi zida likupezeka mu mizinda yambiri: MMPRO ndi MM6, poyerekeza ndi awiri Promark3 RTK.
• Ndi kulondola kotani komwe kungapezeke munthawi yeniyeni komanso momwe zingagwiritsire ntchito kuyendetsa Garmin Legend pamikhalidwe yofananira pamalo akulu kuposa mahekitala atatu.
• Kutayika kwa kulondola ndiko kutalika: XMUMX mita, imodzi, itatu ndi 100 makilomita.

Nthawi yomweyo, tidzayesa mita zamtunda zomwe ndikuganiza kuti zitha kusintha ma kampasi a Suunto ngati atakonzedwa mokwanira, m'matawuni. Kutengera ndi mayeserowa, tiona momwe tingalimbikitsire kuyesayesa kwakumidzi komwe kudzatitengera kuyambira Juni mpaka Seputembala. 

Ife tiwona momwe izo zikupitira.
