Izindleko Zokulinganisa Umhlaba: Yini Ngempela Amanani e-DGPS ne-Total Station
Umlimi ofuna umngcele wesiza sakhe uphawulwe, kanye nomnyango kahulumeni othatha amahekthare angu-40 wesiteshi somfudlana, ngokobuchwepheshe bacela into efanayo: ukulinganiswa komhlaba ovulekile. Kodwa intengo abazoyinikwa ingahluka ngokuphindwe kayishumi, futhi ubuningi balo mehluko abunakho nokusho nokuxoxisana.
Yilapho ukudideka okuningi kuqala khona. Amanani okulinganisa umhlaba ngokuvamile awashicilelwa, ngakho abathengi bathola inombolo engenamongo, noma bacabange ukuthi ukulinganisa ngakunye kubiza okufanayo ngamacala ngamanye. Akukho okulungile kulokho. Ngezansi kuveza ukuthi le mboni yenza kanjani intengo yale msebenzi wemhlaba ovulekile ngempela.
I-Total Station vs DGPS: Izimiso ezimbili zomsebenzi ezihlukile
Womabili amathuluzi asetshenziselwa umsebenzi wokulinganisa i-DGPS ne-RTK, kodwa axazulula inkinga yokunemba ngendlela ehlukile. I-Total Station isebenza ngomugqa wokubona. Ithuluzi kanye ne-prism kudingeka zibonane, ngakho njalo lapho isihlahla, udonga, noma ukugoba komhlaba kuvimba lo mugqa, umlinganisi kufanele ashintshe isiteshi.
I-DGPS isebenza ngendlela ehlukile. Ifunda indawo kusukela kuma-satellite futhi ixhumana ne-base station ngo-radio, ngakho ayidingi umugqa wokubona endaweni yesibili, kudingeka nje ukubona isibhakabhaka esivulekile. Yingakho i-DGPS ibe umgomo wokuzenzakalelayo womhlaba ovulekile, ofinyeleleka minyaka le.
Ilungele kakhulu izisiza ezincane, ezingenazithiyo lapho iphuzu ngalinye libonakala ngqo kusukela enanini elilinganiselwe lezinsetho. Kudinga ukushintsha isiteshi kaningi emhlabeni ongalingene noma onezitshalo.
Ukukhethwa okuvamile kwezenzakalelayo komhlaba ovulekile, izisiza zezolimo, kanye nomsebenzi womngcele we-cadastral. Akudingeki umugqa wokubona, ukumboza indawo yosuku ngalunye ngokushesha, kanye nokunemba okuqhubekayo emihlabeni emikhulu, eqhubekayo.
Kunconywa uma indawo idlula amahekthare angu-200, noma lapho umhlaba ukude ngempela noma ungatholakali ngokuhamba ngezinyawo. Ukulinganisa nge-drone kumboza umhlaba ngokushesha ukwedlula noma yikuphi ukulinganisa okuhambwa ngezinyawo.
Amanani Okulinganisa Umhlaba Ovulekile Ngohlobo
Intengo yomhlaba ovulekile inikwa ngezindlela ezimbili kuye ngobukhulu. Izindawo ezincane, ngokuvamile ngaphansi kwehektha eyodwa, zinikwa intengo eyisamba ngoba izindleko zokuthutha nokuvakashela indawo zomlinganisi kufanele zibuyiswe. Izindawo ezinkulu zinikwa intengo ngehektha, ngenani lehla kancane njengoba indawo ikhula.
1. Ukulinganisa Umngcele noma i-Cadastral
Lolu uhlobo lokulinganisa oluyisisekelo: ukulinganisa umngcele wesiza noma umhlaba wasepulazini kanye nokubala isikhala esiphelele. Lokhu kwakha izinga lokubhekisela ezinye izinhlobo ezimbili zokulinganisa ezingezansi.
| Izinga Lendawo | Izinga Ngehektha |
|---|---|
| Kuze kufike ku-10 Ha | R380 / Ha |
| 10 Ha kuya ku-20 Ha | R285 / Ha |
| 20 Ha kuya ku-50 Ha | R190 / Ha |
| 50 Ha kuya ku-100 Ha | R150 / Ha |
| Ngaphezu kuka-100 Ha | R95 / Ha |
Kwizisiza ezincane kunehektha eyodwa, izinga ngehektha alisebenzi. Abalinganisi ngokuvamile babiza inani eliphansi elingaba u-R1,900 ngokuvakashela indawo, elimboza ukuthutha, izindleko zohambo, kanye nosuku lwenkundla, kucatshangwa ukuthi indawo ikwikhilomitha ezingu-50 kusuka enkundleni yomlinganisi. Ngaphezu kwamahekthare angu-200, ukulinganisa nge-drone ngokuvamile kuyindlela esebenzisekayo kakhulu.
2. Ukulinganisa i-Contour noma i-Level
Ukulinganisa i-contour kuqopha ukuphakama endaweni yonke yesiza egridini elimisiwe, hhayi izingosi zomngcele nje kuphela, okusho ukuthi umlinganisi kudingeka ahambe ngokoqobo yonke indawo engaphakathi yomhlaba. Lo msebenzi owengeziwe wasenkundleni uvezwa entengweni: cishe izikhathi ezingu-1.5 kuya ku-1.8 zezinga lokulinganisa umngcele, okuba cishe R570 ngehektha ngaphansi kwezimo ezijwayelekile.
3. Ukulinganisa i-Topography
I-Topography inezela ukuthwebula izici phezu kwedatha yomngcele nezinga: izakhiwo, imithombo, izihlahla, izinsika zikagesi, imigwaqo, kanye nanoma yiziphi ezinye izici zomzimba endaweni. Lokhu yiyona ephelele futhi ethatha isikhathi eside kunazo zonke ezintathu, ngokuvamile ifika ku-R950 ngehektha.
Ukulinganisa akuwona umsebenzi wenkundla ngamaphesenti alikhulu. Usuku olusetshenzwe endaweni lubonisana cishe njalo namahora angeziwe ehhovisi ecutshungulwa idatha nokulungiswa komdwebo, futhi lo msebenzi wokucutshungulwa ngemuva usuvele wakhiwe kuzo zonke izinga ezingenhla. Inothi lomkhuba wasenkundleni, imisebenzi yokulinganisa umhlaba ovulekile
Amanani Okulinganisa Okuqondile: Imifudlana, Imigwaqo Nemibiko Yokuthelekisa
Akuwo wonke amasilinganisi asuselwa endaweni. Ukuhlelwa kwemifudlana, izindlela zomgwaqo, kanye namaphrojekthi Wombiko Wokuthelekisa Kagesi alinganiswa njengezindawo eziqondile, ngokuvamile nge-Right of Way (ROW) eze ku-50 wamamitha ububanzi. Ikhilomitha eyodwa eqondile cishe ilingana namahekthare amahlanu omsebenzi wokulinganisa olilinganiselwe.
| Uhlobo Lokulinganisa | Ububanzi be-ROW | Izinga |
|---|---|---|
| Ukulinganisa Okuqondile (umfudlana, umgwaqo, umbiko wokuthelekisa) | Kuze kufike ku-50 m | R1,900 / km (R1.90 ngemitha) |
Ukulinganisa umngcele kudinga kuphela amaphuzu omngcele, ngakho ithimba le-DGPS lingamboza cishe amahekthare angu-50 ngosuku. Ukulinganisa i-contour kudinga i-grid engaphakathi, okwehlisela amandla osuku olulodwa kufike cishe kumahekthare angu-20. Ukulinganisa i-topography kunezela ukuthwebula izici kuze kufike kumaphuzu ali-100 ngehektha, okwehlisa amandla osuku olulodwa kakhudlwana, kufike cishe kumahekthare angu-10.
Isidingo somugqa wokubona se-Total Station sisho ukumisa amanye amaziteshi amaningi emhlabeni ofanayo, futhi ukumiswa kwesiteshi ngasinye kuthatha isikhathi sokulinganisa nokucwaninga. Emhlabeni ovulekile, ongenazithiyo, isasebenza kahle, ngokuvamile cishe amahekthare angu-30 ngosuku ekulinganiseni umngcele, kodwa isala emuva kwe-DGPS njengoba izithiyo zikhula.
Ukungangeni kalula, umhlaba ontaba noma okude, imifula noma izihosha ezidlula endaweni, ukujula kwephuzu lezici okuphakeme umthengi akudingayo, kanye nesimo sezulu esimba konke kunezela isikhathi sasenkundleni ngaphandle kwezinga elivamile. Lezi zici zibonakala endaweni yalesosihloko, yingakho intengo ngayinye kufanele isuselwe engxoxweni yangempela ngomhlaba, hhayi inombolo eqinile eyenziwe etafuleni.
Uma indawo idlula amahekthare angu-200, noma lapho umhlaba ukude kakhulu ngendlela yokuthi ukuhamba iphuzu ngalinye kungenzeki, ukulinganisa nge-drone kuba yindlela esebenza kahle kakhulu. Ithimba le-DGPS noma le-Total Station lingamboza cishe amahekthare angu-500 ngosuku ngokulinganisa indawo nge-drone.
Kungani Ukufinyelela Kwasenkundleni Kusanquma Inombolo Yokugcina
Izinga ngalinye elingenhla licabangela izimo ezijwayelekile ngokwengqondo: umhlaba ofinyelelekayo, isimo sezulu esilinganiselwe, kanye nendawo ekwilinganiselwe lohambo olujwayelekile lethimba lokulinganisa. Amaphrojekthi angempela kancane ahlala ehleliwe kanjalo. Ithimba lasenkundleni elenza ukulinganisa kwendlela yomfudlana ngezindawo ezidlula izihosha nemibundu engazinzile lizodinga isikhathi esingaphezulu kunebanga elifanayo eliqondile emhlabeni ovulekile oyisicaba.
Lapha futhi nomsebenzi wokuthola umhlaba unezela ingcindezi yawo. Uma ukulinganisa kusiza ukuthola umhlaba kahulumeni, ukunemba kudingeka kuvikeleke, ngoba imiphumela iqondisa ngqo isinxephezelo umnikazi womhlaba azosithola.
Awuqinisekile ukuthi umhlaba wakho udinga uhlobo luni lokulinganisa?
Ukulinganisa umngcele, i-contour, ne-topography kuxazulula izinkinga ezehlukile futhi kunikwa izinga ngenxa ethile.
Bheka Imiphumela Yokulinganisa i-TopographyBala Izindleko Zakho Ezilinganiselwe Zokulinganisa
Ikhalikhuletha engezansi isebenzisa izinga elijwayelekile lokulinganisa umngcele (indawo) elivela etafuleni elingenhla. Inikeza kuphela isilinganiso sokuqala, inombolo yokugcina yomhlaba wakho ixhomeke endaweni, ukufinyelela, kanye nokujula kwezici.
🔢 Ikhalikhuletha Yezindleko Zokulinganisa Indawo Yomhlaba Ovulekile
Izinga: R380/Ha (kuze kufike ku-10 Ha) · R285/Ha (10 kuya ku-20 Ha) · R190/Ha (20 kuya ku-50 Ha) · R150/Ha (50 kuya ku-100 Ha) · R95/Ha (ngaphezu kuka-100 Ha). Izindawo ezingaphansi kuka-1 Ha zithintwa inani eliphansi elingu-R1,900 lokuvakashela indawo. Ngaphezu kwamahekthare angu-200, ukulinganisa nge-drone ngokuvamile kuyanconywa.
Kumaphrojekthi lapho umhlaba ufaka imifula, izihosha, noma izingxenye ezingahanjwa ngqo, ukumboza kosuku olusebenzayo kuwela phansi kakhulu kunezibalo zamandla e-DGPS ejwayelekile. Ukukubika lokhu kumlinganisi wakho ngaphambi kokuvakasha, hhayi ngemuva, kugwema ukungahambisani phakathi kwesilinganiso sokuqala kanye ne-invoyisi yokugcina.
