Tengani chithunzi kuchokera Google Earth kuti ecw apange

Chosowa: Timagwiritsa ntchito cadastre pogwiritsa ntchito chithunzi cha Google Earth pamafayilo omwe ali opepuka.

Vuto: Ortho yomwe Stitchmaps imatsitsa ili mu mtundu wa jpg, georeference yomwe imabweretsa siyothandizidwa ndi Microstation.

Yankho: Tsitsani chithunzichi ndi Stitchmaps, gwirizanitsani Google Earth ndi Microstation kuti mulowetse zojambulazo ndikuwombera wina ndi mnzake.

Tili ndi chidwi ndi ecw chifukwa ilibe fayilo yowonjezera komanso komwe 200 MB HMR kapena Tiff imatha kulemera 12 MB osataya kwambiri. Tili ndi Stitchmaps ndi Microstation PowerMap V8i, monga tili nayo tidzachita ndi izi ngakhale ndi mapulogalamu ena atha kuchitidwa ndi zochepa.

Tiyeni tiwone momwe izo zikuchitikira:

1. Kutsitsa kwazithunzi. 

Izi tachita nazo Makhalidwe, monga tafotokozera kale. Kupatula kuti talemba kachulukidwe mu Google Earth, kuti ipangidwe pakujambula zithunzizo.

Mu Google Earth izi zatha Onjezani> Polygon, ndipo mumtundu wathu timasankha autilaini yokhala ndi mzere wazitali wa 1.4 yoyera. Tidzachita izi monga chonchi, popeza Microstation silingathe kulowetsa fayilo ya kml mumitundu iyi, kupatula FME kuchokera ku Bentley Map. Koma mtunduwo Powermap Sibweretsa zotsatirazi, kotero kuti tipange makositomala kuti tifunikire kuzijambula.

2. Pangani kugwedeza kwa georeferenced.

Izi zimapangidwa ndi kuchita Fayilo> Chatsopano, ndipo timasankha mbewu ya Seed3D. Kuitanitsa zithunzi za Google Earth sikugwira ntchito pa fayilo ya 2D.

Ndiye tiyenera kuwonjezera georeference ku fayilo, zomwe zimachitika ndi: Zida> Geographics> Sankhani Njira Yogwirizira

Mu gulu lomwe timasankha Kuchokera ku Laibulale, ndipo pakadali pano tikufuna malo a UTM 16 North, ndiye timasankha:

Library> Projected> World (UTM)> WGS84> UTM84-16N

Ngati iyi ndiyo njira yomwe timagwiritsa ntchito kwambiri, titha kudina pomwe ndikuwonjezera pazokonda, kuti tithe kugwiritsa ntchito mosavuta. Timapanga OK ndipo fayilo yathu tsopano ndi georeferenced.

3. Jambulani chithunzi kuchokera ku Google Earth

Kuti tigwirizane ndi Microstation ndi Google Earth timachita Zida> Geographics> Tsatirani Google Earth View. Mwanjira iyi, malingaliro athu akuwonetsa zomwe zili pa Google Earth. Ndikosavuta kuyang'ana kumpoto pamenepo ndi njira yovomerezeka.

Kutenga chithunzi chomwe timachita Zida> Geographics> Jambulani Chithunzi cha Google Earth, timadina pazenera kenako ndikumaliza kutumizidwa. Zomwe tili nazo palibe chithunzi, koma a chitsanzo chapamwamba cha digito, ndi chithunzi ngati katundu wa nsapato.

Kuti tiwone chithunzichi, timayendetsa. Pofuna kuti ndisasokoneze komwe mabatani akutulutsira ali, ndizichita kudzera pamalamulo. Zida> Zofunikira mu> perekani zonse zosalala.  Onani kuti pali bokosi lomwe limatisangalatsa. Chithunzichi, ngakhale sichinasinthike bwino, chimasinthidwa.

4. Kujambula chithunzi

Pachifukwa ichi, choyamba, tipanga mfundo pamakona a chithunzi chomwe chatchulidwa. Izi zachitika ndi lamulo lamapepala, tiwapanga kukhala obiriwira, okhala ndi makulidwe oyimira komanso njira yoyenera kotero kuti ngodya ya rectangle iwoneke. Ngati titaya chithunzicho, timayikanso lamulo lakutipatsa, ndipo sitidandaula kuti tidzakhala olondola chonchi, timakumbukira kuti kulondola kwa Google Earth ndi zoipa kuposa zomwe tingathe kutaya pano.

Pomwe mapepala apangidwa, lembani jpg chithunzi chimene tachilandira ndi Stitchmaps:  Fayilo> Woyang'anira Raster, ndiye pa gulu lomwe timasankha Fayilo> onjezerani> Raster. Tisaiwale kusiya njira yogwira Lembani Mwachangu, chifukwa tidzalowa mwadongosolo.

Timayika mkati mwa bokosi la chithunzi cha imvi, kuti tithe kutambasula kuchokera pamenepo. 

Momwemonso, timapanga mfundo kumakona amakona anayi omwe ali m'chifaniziro cha utoto. Tidzachita izi ndi zofiira kuti tione kusiyana kwake.

Pomaliza tiyenera kukhala ndi chonga ichi:

Kutambasula fano, kuchokera ku Raster Manager panel, tikuwombera kumene pa chithunzicho, timasankha m'litali, ndi njirayi Affine mfundo zoposa 3. Kenako timasankha ngodya iliyonse, kuwonetsa komwe adachokera (ofiira) kupita komwe akupita (wobiriwira) ndipo onse anayiwo akakhala, timadina mbewa kumanja.

5. Sinthani chithunzichi kuchokera ku jpg kupita ku ecw

Tachita, tsopano chithunzi chathu cha jpg chidasinthidwa. Kuti muisunge munjira ina, sankhani, dinani batani lamanja ndikusankha sungani monga. Titha kusankha pamitundu yambiri, kuphatikiza amtengo wapatali ecw kuti iwo analibe mabaibulo a Microstation. 

Ndipo potsiriza tili ndi zomwe timafunikira, kukula kwa 24 MB raster, ndi bokosi la chidwi chathu cha mamita 1225 mbali iliyonse, okonzeka kugwira ntchito.
