Georeference mepu dwg / dgn

Tichazoshandisa shanduro iyi kutsanangura zvimwe kusava nechokwadi munzira inoenderana nekupa maitiro kuCAD mapa.

Tichashandisa muenzaniso yakambovakwa, umo tinogadzira meshonga yeUTM ye16 yekumaodzanyemba kwenzvimbo kubva pane pepa rakakwirira uye kuvaka neAccCAD.

1 The Units

Iyi ndiyo dambudziko guru pakushanda nechinyakare yeCAD tool. Mune mhaka yeAustCAD, zvikwata zvebasa zvakaoma kubata kune vanhuwo zvavo, nokuti kana yakaiswa kwekutanga nekuurayiwa, inobvunza kuti: Uri gorosi here? Zvakanaka, hazvisi izvo zvakasvibirira asi bvunza kana iwe ukashandisa mauniti mumamilimita kana masendimita.

Nyaya yacho ndeyokuti nyika dzedu dzeEnglandese dzimba yacho ndiyo mita, kuitira kuti tigone kuoma nyika kuti zvikonzero zvekugadzirisa zvirongwa hazvina kukosha (zviyero zviyero) ... nezvimwe zvisina basa kana uchitakura zvigadzirwa kana maitiro yemutsara inoda kuwedzera. Uye kunyange zvazvo mavhidhiyo eAcCC achangobatsira anobatsira nechinetso ichi, mafaira akaitwa nemapurogiramu apfuura anochengetedza dambudziko reyuniti pavanoda georeference.

Panyaya ye Microstation, izvi zvinogadziriswa mu "working units” asi nenzira imwechete vanoramba vari mafaera emakadhi pasina georeference. Iwe une kutonga zviri nani pane izvo Microstation inoziva sembeu faira (mbeu faira), uko izvo zvigadziriswe izvi zvinotsanangurwa ... kuti kunyange zvazvo ivo vangava vanokwanisa kuvanzwisisa pakutanga vanobatsira zvakawanda kupfuura zvinyorwa zveAcotCAD kuenda kuAnglo-Saxon.

Ngatiyeukei kuti kana uri kushanda neUTM coordination, uye mepu iri "georeferenced" kune imwe yeaya macoordination, chaunacho ifaira rine hama inoreva grid, asi haisati yave nefungidziro kana Datum, iyo. ndiro rinoshandiswa pazviri.Inozivikanwa se georeference kana absolute reference.

Mune mhaka yangu, "kuitira kuti ndirege kuoma" nezvikwata zveAutoCAD, zvandinoita ndezvokuzarura mepu yenyika yangu muMicrostation, yandinoziva kuti georeferenced, ndinodana AutoCAD faira sereferensi (nokuti haifaniri kutorwa kunze kwenyika. ) uye sarudza bhatani "DWG Sarudzo" apo ini ndinotsanangura kuti zvivako zvebasa zviri "seed file master units", uye kunyanya Attachment Method regai zvive "Coincidence World". Uye makagadzirira, zvisinei kana dwg akanga kushanda millimeters kana masendimita, faira anobvuma basa vamapoka DGN yangu mepu, ipapo kutevedzera mepu nezve faira rangu akaiisa pasi rimwe zita, kuti nzira ndinoziva kuti mepu ane unhu vembeu yangu faira.

... zvakanaka, ndicho chikonzero changu asi chinoshanda ... unogona kuwana kutsveyamisa kwako 🙂

2 Ipa Maitiro

Izvo zvinotevera zviri nyore, iwe unogona kuita zvakawanda nazvo Kazhinji, kunyange zvazvo iwe uine puroti mushure mako iyo inokosha $ 1,500 unogonawo kuzviita ArcGIS :), sezvaanoita Map3D, Microstation Geographics, Cadcorp...

Kuti uzviite neManifold unogadzira faira idzva, wobva wapinza iyo CAD faira "file / import / drawing", iwe unosarudza iyo "dgn" faira sarudzo. Inokukumbira iwe sarudzo yezvikamu zvakakomberedzwa, kwaunogamuchira kukosha kunouya nekukasira.

Ipapo iyo faira inotengeswa kunze kwenyika, ndinodzima poindi uye mitsetse miviri yandisingazive kuti sei yakasikwa. Ndizvo zvaunoita chete"tora uye bvisa"... iwe unotamba ipapo wodzima nekiyi "delete" 🙂

Kugovera fungidziro, sarudza chikamu, kurudyi mbeva bhatani uye sarudza "govera fungidziro"

Rangarira kuti haugone kusarudza "kuchinja fungidziro" nekuti iri cad faira, iyo isina fungidziro.

Mune yangu ini ndichasarudza "Universal Traverso Mercator", Zone 16 Northern Hemisphere uye WGS84 seDatum.

3 Tumira kuneGoogle Earth.

Iyi inzira yakanaka yekutarisa kuti mepu yakanyatso kutariswa, saka ini ndichaitumira kune kml (hapana chikonzero chekuipa iyo geographic coordinate fungidziro). Tinya-kurudyi pane yatova georeferenced chikamu uye sarudza iyo "export" sarudzo, uchisarudza iyo kml fomati.

Kusika munzvimbo dzakasiyana, iwe chete kutevedzera rokuti (pasina kunyange georeference), zvino namatidza, namatidza, namatidza, namatidza, namatidza, namatidza, namatidza, namatidza ... zvino iwe basa munzvimbo dzakasiyana kuti chikamu chimwe nechimwe zvakasikwa. (Component mu Manifold yakaenzana nepamusoro)

Zvino iwe unoshandisa mafirik kml neGoogle Earth, unoshandura kuwanda uye marara emutsara ... uye ikoko une nzvimbo kubva kuMexico kusvika kuVenezuela uye yeSpain.

Kubva pano iwe unogona kukanda mafaira emabasa aya muzvikwata.dwg,.DGN V7 ,.mepu yezvizhinji uye.Kml pamwe nemitambo yenyika yekuchamhembe kwemaHepanland nyika dzenyika dzeAsia, kusanganisira zvitatu zvinoshandiswa kuSpain

... zvose zvakatorwa kubva pane dwg file nyore yakavakwa neExcel.
