Kusintha mapu kuchokera ku NAD27 kupita ku WGS84 (NAD83) ndi AutoCAD
Tisanayambe kuyankhula za chifukwa chomwe tikukhala, zolemba zambiri zakale ili pa NAD 27, pamene maiko onse akugwiritsidwa ntchito ndi NAD83, kapena ambiri amatcha WGS84; ngakhale kuti zonsezi zili zofanana, kusiyana kuli Datum (kumangokhala mu gridi ya UTM).
Ambiri amakumana ndi chisokonezo chokwanira ndikukhulupirira kuti mapu akungoyendetsedwa ndi vector, zomwe zinachitikira Honduras m'mapepala ojambula mapu akuti ndi 202 mamita kumpoto ndi 6 mamita kummawa; Zoonadi izi zingagwiritsidwe ntchito kuntchito, komabe pamene mukubwezeretsa monga momwe ziyenera kukhalira, mapulogalamu a makompyuta amachititsa ntchito zochuluka pa kusintha kwa ellipsoid komwe kumapanganso mapu pomwe onsewo asunthira mu gridi mtengo osati nthawi zonse, kotero sizingagwirizane ndi mapu "angosuntha".
Zitha kuchitika ndi Microstation Geographcis, ARCGis kapena ndi Manifold; pamenepa tiwona momwe tingachitire ndi AutoCAD Map3D. Ndigwiritsa ntchito zomwe ndili nazo (Map3D) mu Chingerezi kotero tidzayesetsa kusunga mayina ena momwe mulili pamndandanda ndi mabatani komanso monga mnzake CADGEEK adafotokozera kale. Muyenera kudziwa kuti AutoCAD Land Desktop ndi AutoCAD Civil 3D, omwe kale anali mapu a AutoCAD adamaliza kukhala pulogalamu iyi yomwe AutoCAD imayitanitsa Map3D, njirayi sinasinthe pamitundu yosiyanasiyana.
Timayamba kuchita ndi mapu opanda kanthu:
Perekani ndondomeko ku mapu oyambirira
1. Tikuyamba kujambula kopanda kanthu
2. Pogwiritsa ntchito malo ogwirira ntchito a "map classic", timapita ku mapu/zida/kugawa dongosolo la coordinate padziko lonse. Mwanjira imeneyi dwg yathu ili kale ndi kachitidwe kofotokozera, ambiri pano akulakwitsa chifukwa amangopereka dongosolo latsopano, zomwe zingayambitse data yolakwika. Pa batani la "Select Coordinate System" timasankha chiyambi.
3. Muchitsanzo ichi, ndili ndi mapu mu NAD27, kotero timasankha dongosololi mu batani la "select coordinate system"; Ndikufuna kupereka izi ku NAD83, ndikuyiyika ku batani lotsatira pagawo lomwelo (chojambula chagwero). Ndi batani la "sankhani zojambula", fayilo (kapena mafayilo) omwe angakanidwe amasankhidwa.
4. Tsopano popeza mapu athu ali ndi njira yolumikizira, timatsegula gulu ngati silinatsegulidwe. Zitha kuchitidwa ndi bala la MAPWSPACE, kenako lowetsani.
5. Tsopano kuchokera pa "map explorer", timadina kumanja pa "zojambula" ndikusankha "attach"
6. Bokosi la zokambirana lomwe likuwonekera limatithandiza kufufuza msakatuli wa fayilo yoyamba, tikaipeza timayika batani la "kuwonjezera"
7. Ndi chojambula chowonjezeredwa, tsopano tikhazikitsa funso. Kuti tichite izi, dinani kumanja pa "funso lapano" kuchokera pagawo lakusakatula mapu, ndikusankha "kutanthauzira".
8. Kuchokera pazotsatira za gulu la Query, dinani "malo", pansi pa "funso type", ndiyeno dinani "chabwino" kuti muvomereze "mtundu uliwonse wa malire". Izi zikutanthauza kuti ngati tiyang'ana zojambula zoyambirira m'magulu ake, ndi "funso lamtundu" lomwe likufotokozedwa, timasankha njira ya "kujambula" monga "mafunso".
9. Pambuyo pofotokozera funsolo, timakanikiza batani la "execute query". Mapu a AutoCAD Mapu 3D akamaliza ntchitoyi, timakulitsa makulitsidwe ndipo mutha kuwona zojambula zokanidwa.
M'pofunikanso ponena kuti ena zinthu Civil 3D amafuna kusuntha kuti zosavuta, monga mlandu wa ziwembu zovuta (kanjedza angapo, mbiri) kapena iwo amene ali monga zilumba (ziwembu mkati ziwembu); Zomwe zili zonyansa mongazo zomangidwa ndi luso lamtundu wina ndi zina zowonongeka. Kawirikawiri amakhala mabungwe kapena magulu omwe amafunika kugwiritsidwa ntchito asanaweruzidwe.

Zikomo, ndi kuyesa kuti muone ngati izi ndi zoona
Moni nonse, posachedwa ndidayamba kugwira ntchito pa AutoCAD Map 3D (yomwe imabwera mu AutoCAD Civil 3D Land Desktop Companion) ndipo ndiyenera kugwira ntchito pa orthophotos kuchokera kudziko langa (Guatemala) vuto ndiloti ndiyenera kupanga chiwonetsero changa chifukwa ndili ndi matanthauzidwe ofunikira kuti ndiyikonze, ngati wina akudziwa kuchita izi kapena ngati ali ndi lingaliro ndithokoza kwambiri, zikomo kwambiri… ..
Maphunziro abwino kwambiri ... komanso mosemphanitsa? Ngati ndili ndi chidziwitso mu WGS84 ndipo ndili ndi magawo amomwe ndingasinthire kukhala datum wamba.
Mukutanthauzira kwa kayendedwe ka machitidwe okha ndi magawo angathe kulowetsedwa kuchokera ku dera lanu ku WGS84. Kodi pali njira iliyonse yochitira izo?
Mwini, ndawerengera magawo pansi pa Bursa-Wolf chitsanzo, koma sindikudziwa ngati Mapu Autocad amagwiritsa ntchito migwirizano yofanana.
Zikomo kwambiri.
zikomo chifukwa cha thandizo lanu g! Ndidzachita mayesero ena ndikudziwitse zotsatira.
Ndi Microstation:
Choyamba muyenera perekani ndondomeko kukunyalanyaza kwanu, kusankha malo a UTM 16 North, ndi deta yomwe muli nayo chidziwitso.
Kenako mumasankha lamulo lomwe kale amabweretsa kuphatikizapo Microstation, kutumiza kwa kmz, iye mwiniyo amachititsa kutembenuka kupita ku malo ndikusankha deta ya wgs84
Ndikukuchenjezani, izi sizikuthandizani inu Microstation XM yokha, mukukhala Mapu a Bentley kapena Microstation Geographics
Ndi AutoCAD:
Pamaso pa nkhondo yomenyana ndi FDO Civil 3D, muyenera tione kutambasuka pamakhala ndi AutoDesk kuti katundu zitsanzo DWG kuti KML

Hello Ine ndine woyamba m'munda ntchito mapu XY amayang'anira kapena kukhala lathyathyathya ngati ndimagwira ntchito MicroStation MX kapena AutoCAD Map3d monga convierto kumpoto ndi longuitud, ndiye analenga wapamwamba KML ndi kuona file wanga Google Eart m'dera UTM ndi 16 Ndimachokera ku El Salvador, ndikukuthokozani chifukwa cha chithandizo chanu.
Ndikufuna pulogalamu yamapulogalamu yomwe imapanga utm mesh mosavuta ku Fayilo ya Autesk Mapu 3D, yomwe ine ndinali nayo kwa nthawi yakale, imapanga zolakwika ndikusiya ntchitoyo
mmm ine sindikuganiza kuti ndikubweretsa chida cha cholinga chimenecho
Ndinkangotchula kuti ndiwatenge iwo ndi autocad mapu 3d
Hello Geobruu, mu positiyi ikufotokozera momwe mungamangire ... muzolumikizana zina mu positi malingaliro amafotokozedwa kuti amvetsetse.
zonse
Chimene sindingathe kuchita ndikujambula mizere yomwe ikuimira dongosolo la utm
Ndagwiritsa ntchito zomwe pulogalamuyo imabweretsa mwachinsinsi; Malingaliro operekedwa ndi malo a m'deralo ndi vectorial displacement koma mwachidziwitso sichigwira ntchito bwino chifukwa momwe maulendo amayandikira ku equator, mawotchi amatha kusintha.
Chimene chikuchitika ndi chakuti ku Honduras, dziko lonse likugwa m'dera lomwelo (16) ndi gawo lochepa chabe m'dera la 15.
Pamapeto pake, poyerekeza njira ziwirizi ndi zochepa kusiyana ndi masentimita khumi kumwera (monga momwe maulendo amayendera kupita ku equator)
Chabwino, tsopano zikuwonekera.
Pa nkhani yeniyeni ya dera lanu, kodi mwawerengera za kusintha kwanu, kapena mumagwiritsa ntchito zomwe zimaperekedwa ndi Geographic Service kapena mumagwiritsa ntchito zomwe pulogalamuyo imabweretsa mwachisawawa?
Ndiko, kodi zotsatira za kusinthika kwenikweni, ndizomwe zili, kapena zokhazokha (mamita angapo)?
Inde, ndinkasokonezeka, ndinayesera kufotokoza.
mu galasi yoyamba, mu gulu lomwelo, muyeso yoyamba timasankha mawonekedwe oyambirira ndipo mwachiwiri timakonzekera dongosolo, ndiye mu batani kuti tisankhe kujambula, timatenga mapu omwe tikufuna kubwezera.
Zimene sindikumvetsa kapena zomwe sindikuziwona ndizomwe mumatanthawuzira dongosolo loyamba la NAD27.
