Georeferencing mufananidzo weGoogleEarth

Ndakanga ndambotaura pamusoro teerera an orthophoto kuGoogle Earth dai taiziva iyo georeference.

Iye zvino ngatimboedzei pane zvakatarisana, kana tine maonero eGoogleEarth, tingaitora sei uye georeference iyo.

Chinhu chokutanga ndechekuti, tinoziva zvakanaka uye nei kwete Google Earth, zvisati zvaitika isu takatotaura pamusoro pazvo. Zvakanaka, chinhu chekutanga ndechokuti maonero acho aoneke, uye zvatinoda ndezvekutora mufananidzo iwoyo uye georeference. Iwe unofanirwa kushandura nzvimbo yacho kuti urege kushandura maonero ekutsvaga matatu-dimensional, unofanirawo kuva nechokwadi chokuti kambasi iri kuchamhembe uye maonero akafanana.

1. Kuratidza nzvimbo inofarira

Iwe unofanirwa kugadzira bhokisi rine polygon tool yeGoogle Earth, mumakona eruva raunoda kugura. Zvino iwe unoswedera zvakakwana kuti uwane urongwa hweUTM, uchiisa pointer pamusoro pekona, unofanirwa kuchengeta mupfungwa kuti kururama kweGoogleEarth kune mamiriyoni makumi matatu mamita kuitira kuti usazvidya mwoyo nezvakawanda.

Iye zvino tava kuzocheka bhokisi, tinofanira kutama kuitira kuti magwaro nekambasi zvisati zviri mukati mebhokisi uye tinogadzira zvinyorwa zvitsvuku nebhokisi uye tichikopa iyo kupendesa.

Pano iyi inogona kuderedzwa mupende, nokuti kuzviita nenzira yakanyanyisa ndiko kuparadza kwemaawa pakati pekuti ruvara rutsvuku ruchagara mukati kana kunze. Ndinosimbisa, kutengesa kweGoogleEarth hakufananidzi kurwira kwemamita mashomanana. Iye zvino tinovhura nehofisi yeFinner Picture (iyo inouya neWoldws) kuti icheke mitsetse nechinakidza zvikuru pamwe nekusarudzwa kwezvirimwa nekudhonza mhedziso, ndinozviita pano nokuti ndinoda kuvandudza zvishoma kusiyana kwechifananidzo.

Uyu ndiwo mufananidzo unoguma nechinopenya uye kupenya kuchinja.

2. Kuisa bhokisi ku Microstation

Iye zvino tava kuenda kune georeference iyo uchishandisa Microstation V8, data inoratidzirwa inonyorwa mune zvakanakisisa kuitira x, y, z uye isu tinoichengeta mu .txt format ye z zero kushandiswa. Izvi ndezvekuti usapinda mahwende nekiyi inofamba netsoka.

Iye zvino mu Microstation kana xyz data inoshandisa palette haina kubviswa, itaira nayo nemashandisi / mabhokisi ekushandisa uye usarudze pakuguma. Nechidziro ichi tinoshandisa mapepa kubva kune faira yakakurumbira uye ndizvo zvazviri, isu tatova nemafungiro ekutura chifananidzo.

Kuita kuti pfungwa idzi dziwedzere kuonekwa, unogona kuchinja mararamiro uye kuwanda kwechinhu chacho.

3. Georeferencing mufananidzo mu Microstation

Ikozvino chasara kupinza mufananidzo, nekuda kweizvi isu tinoshandisa raster maneja kuraira, ne "nzvimbo inopindirana" sarudzo uye kuiisa mukati memapoinzi mana.

Kuti tidzire, tinoshandisa mutemo we warp, nechinangwa chechina, uye kuratidza imwe imwe yekona yemufananidzo kuburikidza nekunyorera pfungwa dzayo dzinofananidzwa.

Apo patakaratidza pfungwa ina tinonyatsotsvaga pahwindo uye wapedza. Iyo georeferenced googleearth image. Iye zvino kubva pano chifananidzo ichi chinogona kuponeswa nechinangwa che georeferenced.

4. Kupwanya pamusoro pekukosha kweizvi 🙂

Ini ndinomanikidza sekupedzisira mazano, iyo nguva refu yakarongwa ndatsanangura kuti ndipedze nguva shoma yerwendo urwu rwakatotitadza ini. Usashandise izvi pamabasa akaoma, nokuti data yeGoogleEarth haigoni kushanda iyo. Kuti ndikuratidzei muenzaniso, ndinosangana nemepu yefaji.

Kuvandudza, kutora mifananidzo nenzira inorwadza kunogona kuitwa nekubatanidza zvakananga kubva manifold system kana ne Google Maps Image Downloader
