Onani UTM ikugwirizanitsa pa Google Maps, ndikugwiritsa ntchito ANY! Njira zina zogwirizana
Mpaka pano zakhala zofala onaninso UTM ndi maiko ozungulira mu Google Maps. Koma nthawi zambiri kusunga zomwe Google imathandizira ndi WGS84.
Koma:
Bwanji ngati tikufuna kuwona Google Maps, mgwirizano wa Colombia ku MAGNA-SIRGAS, WGS72 kapena PSAD69?
Kugwirizana kwa Spain ku ETRF89, Madrid 1870 kapena REGCAN 95?
Nanga bwanji za mgwirizano wa Mexico ku GRS 1980 kapena International 1924?
Masiku angapo apitawo pali makina omwe amakulolani kuchita izi, ndipo ndi PlexScape WebServices. Kuchokera kwa anzanu achi Greek opanga a Plex.Earth, yomwe imaphatikizapo deta pakati pa Google Earth ndi AutoCAD, yomwe mwa njirayi tsopano imasuta kwambiri kwa AutoCAD 2013 yomwe inasintha malamulo a masewerawo.
Ndipo ntchito iyi ya PlexScape imathandizira zopanda kanthu Zogwirizana ndi 3,000 ndi 400 Datums, zofanana ndi Plex.Earth zimathandiza.
Tiyeni tiwone mayesero: Ndiyesera kufotokozera sitepe ndi sitepe chifukwa moona mtima mawonekedwewo sali oyenera poyamba pakuwona:
Ndili tsopano ku Bogotá ndipo ndikufunitsitsa kuona kusiyana kwa mgwirizano pakati pa WGS84 ndi SIRGAS:
Eya, tiyerekeze kuti ndili pangodya Topoequipment, monga momwe tawonera pa mapu:
PlexScape Web Services, ili ndi mautumiki atatu pano: Imodzi ndikutsata kosavuta kudziwa mgwirizano wa mfundo (Kukonzekera Kutsata), wina kuti apeze mapu pa mapu ndi kuwatsitsa kwa kml / txt (Tsegulani Digitizer) ndipo ina ndiyo yomwe tidzakagwiritsiranso ntchito, yotchedwa Sungani Maofesi.
1. Sankhani Njira Yoyambira
Pachifukwa ichi timasankha patsamba lakumanzere, dziko lomwe timakonda. Pankhaniyi, Colombia, ndipo ikasankhidwa, tiwonetsa WGS84 ngati Datum la chidwi.
Pakati pa latitude / longitude tab ndi Easting / Norting pali zosankha zosiyanasiyana. Chosangalatsa ndichakuti ali ndi zisa ndi dziko chifukwa zingakhale zopusa kuzifufuza pakati pa ambiri omwe dongosololi limathandizira.
2. Malo oyambira
Pachifukwa ichi, kukhala ndi malo omwe amatikonda akuwoneka pamapu, timadutsa mbewa pazithunzi zapansi ndikusankha "Bweretsani chizindikiro pa mapu", ndi izi tiwonetsa chidwi pamapu. Kenako timachikokera kumalo enieni kumene tikufuna kuchiyika. Zomwezo zitha kuchitika ndi ma tabo apamwamba, koma zikuwoneka kuti ndizothandiza kwambiri kuchita kuchokera pachithunzichi ndipo ndikuwonetsa mwanjira yonseyi.
Ngati tikufuna kudziwa kugwirizana kwa malo omwe tapeza, ndiye timayandikira chizindikirocho ndikusankha "Pezani zolumikiza kuchokera ku chilemba", ndi izi mu gulu lathu mgwirizano uwonetsedwa.
Ndipo ngati zomwe tikufuna ndikuyika dongosolo linalake, ndiye kuti timalilemba pagawo ndikuyendetsa pa chithunzi chomwe timasankha "Ikani chizindikiro ku makonzedwe", ndipo ndi ichi mfundo idzakhala mu mgwirizano womwe umatisangalatsa.
3. Onani makonzedwe a UTM
Kuti tidziwe momwe UTM ikugwirizanitsa pa mfundoyi, tiwonetsa malo owonetsera. Ngati mukukayika, titha kusankha imodzi mwazo, ndikusankha "Onetsani malire” malo olembedwa buluu akuwonekera. Thandizo lalikulu chifukwa tizikumbukira zimenezo Colombia sikuti imangogwera m'madera Kumpoto kwa 17, 18 Kumpoto ndi 19 Kumpoto komanso komweko koma kumwera kuyambira pomwe dzikolo lidawoloka ndi Ecuador ndi zomwe zimachitika m'magawo asanu ndi limodzi. Chifukwa chake, asintha madera awo omwe amalemetsa miyoyo yawo pang'ono.
Pankhaniyi, tasankha UTM Zone 18 N ndipo kwenikweni, tikuwona kuti pali mfundo yathu.
3. Sunthani mgwirizano kuchokera kumanzere kupita kumanja
Pakadali pano, zomwe tawona ndi momwe tingawonetsere UTM yolumikizira mu Google Maps. Koma tili ndi chidwi chowona mgwirizano womwewo mu njira ina yolumikizira, pamlandu wa MAGNA-SIRGAS. Choyamba, timagwiritsa ntchito muvi wobiriwira kuti tiwonetse kuti zofananira zimamasuliridwa kuchokera kumanzere kupita kumanja. Izi zimachitika ndikudina ndipo chomwe chingatisangalatse ndikuti mbali zonse ndizofanana.
Tsopano kuti titsegule cholozera choyenera, timachita zomwezo: Yendani pamwamba pa chithunzicho, ndikusankha "Bweretsani chizindikiro pa mapu“. Ikatera kwina, timafufuzanso malowo ndikuwonetsa "Sungani chizindikiro cha mapu” ndi kufananiza mgwirizano “Ikani chizindikiro ku makonzedwe".
Chizindikiro choti zonse zili bwino ndikuti pointer ya buluu iyenera kukhala yofanana ndi pointer ya bulauni ngati njira yolumikizira ndiyofanana onse. Ili ndi chisokonezo, koma chimagwira.
4. Dziwani mgwirizano wa WGS84 ku SIRGAS
Pazimenezi timasintha kuchokera ku WGS84 kupita ku SIRGAS pagawo lakumanja. Kenako timasunthira pamwamba pa chithunzicho ndikuti "Pezani zolumikiza kuchokera ku chilemba", kotero timapeza mgwirizano wa mfundo yomwe tili nayo kale koma mu dongosolo lina. Zindikirani kuti mu lat/lon mgwirizano ndi wofanana, chifukwa SIRGAS imachokera pa WGS84.
Koma ngati tiwona zomwe zimachitika m'mayunitsi a UTM, mgwirizanowu mu X umasiyana masentimita atatu ndipo mgwirizanowu ndi Y wina sentimita. Ndipo ichi ndichifukwa chake titha kunena kuti machitidwe onsewa ndi ofanana. Tikamayenda, kusiyana kumeneku kumasintha mamilimita. Ndikufotokozera kuti izi zikugwirizana ndi magawo omwe PlexScape Web Services yakhazikitsa, chilichonse chachilendo chiyenera kufotokozedwa chifukwa zandichitikira kangapo m'mbuyomu.
5. Dziwani mgwirizano mu PSAD
Titha kusankha dongosolo lina lililonse, ndikupempha kuti libweze mgwirizano ndi "Pezani zolumikiza kuchokera ku chilemba“. Cholozeracho sichiyenera kusuntha, popeza tili pamalo omwewo, zomwe zikubwerera kwa ife ndizogwirizanitsa mu dongosolo lina. Pachifukwa ichi, mu PSAD 1956 mfundo yomweyi ili ndi ma coordinates X=604210.66 Y=512981.6.
Tangoganizani, kuti zomwe tikufuna kuwona ndizofanana mu machitidwe onse awiri (osati mfundo imodzi), kotero timatengera kugwirizanitsa kuchokera kumanzere kupita kumanja ndiyeno "Ikani chizindikiro ku makonzedwe” ndipo pamenepo tiri nazo. Mgwirizano womwewo pansipa, m'magulu onse awiri, koma mfundo yabuluu imagwera kwa ife 228 mamita kumadzulo ndi mamita 370 kumwera.
Chida cha PlexScape Web Services ndichosangalatsa. Mwanzeru zanga zokha. Tsiku lina tidzakambirana zina mwamautumiki awo, zomwe zina zimalipidwa, kuphatikiza kutembenuka komweku kuchokera pa fayilo yokhala ndi mfundo zambiri.
