Tumira Google Earth mufananidzo kune ecw format

Iko kudiwa: Isu tinofanirwa kushanda cadastre tichishandisa iyo Google Earth mufananidzo mune georeferenced fomati iri yakapusa.

Dambudziko: Iyo ortho iyo Stitchmaps kurodha iri mu jpg fomati, iyo georeference iyo inounza haina kutsigirwa neMicrostation.

Mhinduro: Dhawunirodha chifananidzo neStitchmaps, enzanisa Google Earth neMicrostation kupinza iyo georeferenced kubatwa uye warp imwe ichipesana.

Isu tinofarira ecw nekuti haina kugara yeiyo georeference faira uye uko 200 MB HMR kana Tiff inogona kuyera chete 12 MB isina kurasikirwa zvakanyanya muhunhu. Tine Stitchmaps uye Microstation PowerMap V8i, sezvatinazvo tichazviita neizvi kunyangwe nemamwe mapurogiramu angaitwe nematanho mashoma.

Ngationei kuti zvinoitwa sei:

1. Mufananidzo unotora. 

Takaita izvi ne Stitchmaps, sezvatotsanangurwa kare. Kunze kwekunge isu takadhirowa rectangle muGoogle Earth, kuitira kuti iiswe mukutorwa kwemifananidzo.

MuGoogle Earth izvi zvinoitwa ne Wedzera> Polygon, uye muchimiro tinosarudza rondedzero ine ukobvu hwemutsara hwe1.4 chena. Tichaita izvi seizvi, nekuti Microstation haigone kuendesa kml faira mune idzi shanduro, kunze kweBentley Map's FME. Asi iyo vhezheni Powermap haunounisi basa iri, saka kuumba rutsanga tichatofanira kuzviita nekukwevera pamufananidzo.

2 Ita DNA georeferenced.

Izvi zvakasikwa nekuita Faira> Nyowani, uye isu tinosarudza Mbeu3D mbeu. Google Earth mufananidzo kupinza haishande pane 2D faira.

Zvadaro tinofanira kuwedzera georeference kune faira, iyo inoitwa ne: Zvishandiso> Geographics> Sarudza Coordinate System

Mune mapaneti atinosarudza Kubva kuMabhuku, uye kubva panguva ino isu tiri kufarira UTM 16 North, saka takasarudza:

Raibhurari> Yakafungidzirwa> Nyika (UTM)> WGS84> UTM84-16N

Kana iyi iri iyo sisitimu yatinoshandisa zvakanyanya, tinogona kudzvanya -kwira uye kuwedzera kune zvatinoda, kuti tikwanise kuwana zviri nyore. Tinoita OK uye ikozvino faira yedu ndiyo georeferenced.

3. Tora mufananidzo kubva kuGoogle Earth

Kugadzirisa Microstation neGoogle Earth Zvishandiso> Geographics> Tevedza Google Earth View. Nenzira iyi, maonero edu ari kuratidza izvo zviri paGoogle Earth. Izvo zvirinani kuve wakanangisa kuchamhembe uko uye nenzira inogamuchirwa.

Kutumira chifananidzo chatinoita Zvishandiso> Geographics> Tora Google Earth Image, tinodzvanya pachiratidziri tobva tapedzisa kutumirwa. Zvatinazvo ipapo hachisi mufananidzo, asi a digital plot model, nemufananidzo sepfuma yezvipfeko.

Kuti tione mufananidzo, tinomhanya kupa. Kuti usanetseke pane mabhatani ekupa, ini ndichazviita kuburikidza nemirairo yekuraira. Zvishandiso> Kiyi mu> ipa zvese zvakatsetseka.  Ona kuti pane bhokisi rinotinakidza. Ichi chifananidzo, kunyangwe ichigadziriswa zvisirizvo, inoratidzirwa.

4. Georeferefera mufananidzo

Kune izvi, kutanga, isu tichagadzira mapoinzi mumakona eiyo georeferenced mufananidzo. Izvi zvinoitwa nemapoinzi kuraira, tichazviita zvakasvibirira, zvine ukobvu hwekumiririra uye nenzira yakakodzera yekuti kona rekatekete iri kuoneka. Kana isu tikarasikirwa nemufananidzo, isu tinoita iyo yekupa rairo zvakare, uye isu hatinetseke nezve kunyatsoita chaizvo, tinorangarira kuti iyo kusarurama kweGoogle Earth Zvakaipa kudarika zvatinogona kurasikirwa pano.

Kana imwe nguva mapepa aitwa, tinoisa jpg jpg chinyorwa chatakatsvaga ne Stitchmaps:  Faira> Raster Manager, ipapo mubato ratinosarudza Faira> batanidza> Raster. Ngatirege kukanganwa kusiya sarudzo ichishanda Isa Inopindirana, nokuti tichazopinda mairi nemaoko.

Tinoriisa mukati mebhokisi remufananidzo wakavepa, kuitira kuti tigone kutambanudza kubva ipapo. 

Nenzira imwecheteyo, isu tinogadzira makona emakona eraki iri mumufananidzo wevara. Tichaita izvi nezvitsvuku kuti tione mutsauko.

Pakupedzisira tinofanira kuva nechinhu chakadai:

Kuti tambanudze chifananidzo, kubva kuRaster Manager panel, tinonyatsotsvaga pafananidzo, tinosarudza yakarukwa, neyo nzira Affine anopfuura anopfuura matatu mapoinzi. Ipapo isu tinosarudza kona imwe neimwe, tichiratidza poindi yekwatangira (tsvuku) kunzvimbo yekuenda (girini) uye kana vese vana varipo, tinobaya-kurudyi mbeva.

Chinja mufananidzo kubva jpg kuenda ecw

Zvaitwa, ikozvino yedu jpg mufananidzo waitwa georeferenced. Kuti uchengetedze mune imwe fomati, sarudza iyo, tinya kurudyi mbeva bhatani uye sarudza save as. Tinogona kusarudza kubva pamafomati mazhinji, kusanganisira anokosha ecw kuti vakanga vasina Microstation versions. 

Uye pakupedzisira tine zvatinoda, raster ya 24 MB muhukuru, nebhokisi rekufarira kwedu mamiriyoni 1225 kumativi ose, akagadzirira kushanda.
