Chengetedza mapoka emugwagwa kubva kuGoogle Earth

Kuziva kwedu, hapana chirongwa (zvakadaro) chinogona kurodha mumigwagwa yeGoogle Earth mumhando ye vector. Kunyangwe iwe uchigona kubva kuOpen Street Mamepu, zvakashata hapana anobva kumaguta ese.

Asi kana mumwe munhu aifarira mumigwagwa yeGoogle Earth, nzira yekubuda nayo ndeyokuvadhawunirodha semufananidzo, wobva waita semhuka pavari. Heano mamwe matipi ekudzora iwo huwandu hwehuswa:

1. Isa chifananidzo chemasikati

Isu tinoita izvi, kuitira kuti iyo satellite satellite isapindire uye inovandudza kuoneka kwemigwagwa. Mufananidzo mutema bmp unogadzirwa muMspaint uye inodaidzwa kubva kuGoogle Earth, uchiutambanudza pamusoro penzvimbo yekufarira.

2. Dhaunirodha mufananidzo ne Stitchmaps

Iye zvino, achishandisa Stitchmaps, takasarudza mifananidzo inotitendera kuti tione magwaro ehupamhi pasi pevector yemugwagwa.

Onai, kunyange zvazvo Google Earth isina kuona yose migwagwa pakakwirira kwechifananidzo, Stitchmaps zvose, tinosarudza kukwirira kwepasi, munyaya ino 384 mamita.

Kana iyo mosaic yatsanangurwa, isu tinoraira kurodha pasi, uye kumirira iyo mosaic kuti ienderane. pakupedzisira tinoichengeta netiff fomati, uye neka calibration faira yeOziExplorer (.map). Mufananidzo wacho unotaridzika seizvi: iwo mufananidzo kurudyi kuwedzera.

Sevabereki, kana tichida kuzvishandura ku .ecw, in Global Mapper isu tinouyisa mukati, ndokupa iko kuratidzira uye kuudza iyo kuti igadzirise kubva kune .map faira. Ipapo inogona kutumirwa kune .ecw yekubata zvirinani kubva kune chimwe chirongwa.

3. Dzokorodzisa nehurongwa hwekugadzirira

Dhora rakatarisana nemutsara inogona kuva hafu iyo inoshungurudza, kana iwe uchida kutama nekukurumidza, unogona kushandisa chirongwa chekugadzirisa zvinhu zvakadai, Microstation Descartes.

Zvinonzwisisika kuti mufananidzo we .ecw uri georeferenced, (kunyange zvaigona kuitwa kubva kuDescartes), chii chinouya kushandura iwo mufananidzo kuve vector, nenzira imwecheteyo yatinoratidza mune imwe nzvimbo yapfuura.

Chifukidziro chakagadzirwa cheye toni tsvuku, uye imwe yeakachena toni uye tobva taiudza kuti ishandure ivo ive vector ine topological yekuchenesa. Chikamu pane icho chinyorwa, iyo vector haigadzirwe, isu tichafanirwa kuita mubatanidzwa netsoka, kunyangwe kana iwe uchida kutora mukana weDescartes, zvinokwanisika kuti iye achashandura iwo ese iwo manzwi ezvinyorwa kuita grey yemugwagwa, ndosaka takazviita zvidiki. Kana iwo mavara achizo kuve vectorized, shandisa rairo yezvakatemerwa zvinyorwa.

4. Kana musingaiti Microstation Descartes

Inofanirawo kushanda zvakafanana neAustDesk Raster Design, ArcScan, siyana GIS, uye kunyange Corel Trace.
