Te Whakamahinga o te Hangarau GIS i roto i te Ahuwhenua
Kei te anga whakamua ngā wero uaua haere o te ahuwhenua o ēnei rā: te huringa āhuarangi e kore e taea te matapae, te hekenga o te whenua, te korenga o te wai, te piki me te heke o ngā utu whakauru, me ngā tono mō te whakaputanga nui ake me te iti ake o te pānga ki te taiao. I waenganui i ēnei āhuatanga, me whai huarahi atamai ake ngā kaimahi pāmu me ngā kaipupuri hea ki te mārama ki ō rātou whenua, ki te whakahaere i ngā hua, me te whakatau i ngā whakataunga e ahu mai ana i ngā raraunga. Ko tētahi hangarau e whakamahia whānuitia ana hei whakatutuki i ēnei hiahia ko te GIS (Geographic Information System), he pūnaha e taea ai te kohikohi, te penapena, te tātari, me te whakaatu i ngā raraunga e tohutoro ana ki te wāhi.
Mā te GIS ka āwhina i te whakarerekētanga o te ahuwhenua mai i te huarahi "noa" ki te whakahaere motuhake ki te wāhi—he whakahaere e urutau ana i ngā mahi ki ngā āhuatanga rerekē puta noa i ngā rohe rerekē o te whenua. Mā te mārama ki ngā rerekētanga o te momona, te makuku, te pari, me te mōrearea o te whakararuraru, ka taea te whakatau tika ake i ngā mea pēnei i te whakatō, te whakamakuku, me te whakahaere pepeke. Nō reira, ka piki ake te hua, ka whakahaeretia ngā utu, ā, ka whakaitihia ngā pānga ki te taiao.
He aha te GIS, ā, he aha tōna hiranga mō te ahuwhenua?
Ko te GIS he huinga o ngā pūmanawa, ngā taputapu, ngā raraunga, me ngā tikanga tātari e whakamahia ana hei mahere me te tātari i ngā mōhiohio e ahu mai ana i te tauwāhi. I roto i te horopaki ahuwhenua, ka uru atu pea ki ēnei mōhiohio ngā mahere o ngā rohe whenua, ngā momo oneone, ngā mahere pari, te tohatoha hua, ngā mahere whakamakuku, tae atu ki ngā whakaahua amiorangi o ngā āhuatanga tipu.
Ko tētahi painga matua o te GIS ko tōna kaha ki te whakauru i ngā puna raraunga maha ki roto i tētahi anga ā-wāhi kotahi. Hei tauira, ka taea te whakakotahi i ngā raraunga matūkai oneone mai i ngā whakamātautau taiwhanga me ngā mahere whenua me ngā whakaahua amiorangi hei tautuhi i ngā wāhi ka pāngia pea e te korenga o te hauota, te ahotea wai rānei. Mā tēnei ka taea te whakatau i runga i te tātari pono, kaua ki te whakapae noa.
Ngā Pūtake Raraunga mō te GIS Ahuwhenua
Ko te angitu o te whakatinanatanga o te GIS e whakawhirinaki nui ana ki te kounga me te tino o ngā raraunga. I roto i te ahuwhenua, ka ahu mai ngā raraunga GIS i ētahi puna:
1. Whakaahua amiorangi: Whakamahia hei aroturuki i te hauora o ngā tipu, te uhi whenua, ngā huringa o ngā wā whakato, me te kimi i ngā rerekētanga tipu mā roto i ngā tohu tipu pēnei i te NDVI.
2. UAV: Ka whakarato i ngā whakaahua taumira teitei hei tirotiro taipitopito i ngā āhuatanga o ngā tipu, hei tauira, ngā tohu o te mate rau, ngā wāhi waipuke, te kino rānei o ngā pepeke.
3. GPS me te mahere whenua: Hei mahere i ngā rohe whenua, i ngā raina whakamakuku, i ngā pūwāhi tauira oneone, me te tūranga o ngā tipu, o ngā wāhi whakamātautau rānei.
4. Ngā pūoko oneone me te rangi (IoT): Te whakaputa raraunga mō te makuku oneone, te pH, te pāmahana, te ua, me ētahi atu tawhā ka taea te hono atu ki ngā mapi.
5. Ngā raraunga whakahaere me ngā raraunga tatauranga: Pērā i ngā rohe o ngā kāinga, ngā whatunga rori, ngā raraunga hua, me ngā rekoata whakaputanga mō te tātari tauine rohe.
Mā te whakakotahi i ēnei raraunga, ka whakaratohia e te GIS he pikitia whānui o ngā āhuatanga ahuwhenua mai i te tauine whenua ki te tauine whenua.
Te Whakamahinga o te GIS i roto i te Ahuwhenua
1. Te Mahere me te Aromatawai i te Tikanga o te Whenua
He tino whai hua te GIS mō te whakatau i te pai o te whenua mō ngā hua motuhake. Ka taea te mahi tātari mā te whakakotahi i ngā taurangi pēnei i te momo oneone, te pH, te wātea o te wai, te teitei, te pari, me te pāmahana. Mai i tēnei whakakotahitanga, ka hangaia he mahere rohe, pēnei i te "tino pai," "tino pai," "kāore i te pai." He whai hua ēnei mahere mō te whakamahere i te whakawātea whenua, te kanorau hua, me te whakawhanake i ngā rohe ahuwhenua whakauru.
2. Te Ahuwhenua Tika
I roto i te ahuwhenua tino tika, ka arohia ngā rerekētanga o ngā āhuatanga i roto i te mara kotahi. Ka whakamahia te GIS hei waihanga i ngā rohe whakahaere i runga i ngā rerekētanga oneone, i te pai rānei o te hua. Kātahi ka taea e ngā kaimahi pāmu te whakatinana i te whakamomona tere rerekē, ina rerekē ngā horopeta tongi i waenga i ngā rohe. Ka pā anō te kaupapa ki te whakakōhatu, te whakato, me ngā maimoatanga patu pepeke. Ehara i te mea ka whakapiki ake i te whai huatanga o te whakaurunga engari ka whakaitihia hoki te parahanga mai i te whakamahinga tongi nui.
3. Te Aroturuki i te Hauora o ngā Tipu me te Kitenga Moata
Mā te whakamahi i ngā whakaahua amiorangi, i ngā whakaahua rererangi rānei, ka taea e te GIS te āwhina i te aroturuki i te hauora o ngā hua. Mā ngā tātaitai tipu ka āwhina i te tautuhi i ngā wāhi e pāngia ana e te ahotea, pērā i te korenga o te wai, te korenga o ngā matūkai, te pakarutanga rānei o te mate. Ka taea te tohu i ngā wāhi raruraru ki runga i te mapi, ā, ka taea e ngā tīma mara te whakahaere i ngā tirotiro i te papaanga hei whakatau i te take. Mā tēnei huarahi ka penapena wā nā te mea kāore e hiahiatia kia whakahaerehia ngā tirotiro puta noa i te mara katoa.
4. Te Whakahaere i te Whakamakuku me ngā Rauemi Wai
He mea nui te wai i roto i te mahi ahuwhenua. Ka taea te whakamahi i te GIS hei mahere i ngā whatunga whakamakuku, ngā puna wai, me ngā tauira rere. Mā te whakamahi i ngā raraunga whenua (hei tauira, mai i te Tauira Whakateitei Mamati (DEM), ka taea e te GIS te tātari i te ahunga rere me te kohikohinga o te wai, ā, mā reira ka tautuhia ngā wāhi e pāngia ana e te tauraki, e te waipuke rānei. Ina honoa ki ngā pūoko makuku oneone, ka taea te hanga i ngā kaupapa whakamakuku kia tika ake, ka whakaiti i te para wai me te pūngao.
5. Te Whakahaere i ngā Mate me ngā Pepeke e Hangai ana ki te Wāhi
He maha ngā wā ka pāngia ngā tauira horapa o ngā pakarutanga o ngā pepeke me ngā mate e ngā āhuatanga o te taiao. Mā te GIS, ka taea te mahere me te tātari i ngā wāhi e pangia ana e te pepeke hei tautuhi i ngā whanaungatanga ki ētahi atu āhuatanga pēnei i te haumākū, te tawhiti mai i te pūtake o te mate, te ahunga hau rānei. He whai hua ēnei mōhiohio mō ngā rautaki whakahaere pepeke whakauru, pēnei i te whakatau i ngā wāhi hopu, ngā rohe karantini, ngā kaupapa matua rehu rānei.
6. Te Matapae i te Kotinga me te Tātari i te Hua
Mā te GIS ka āwhina i te tātari i ngā rerekētanga o ngā hua o te hua i roto i te wā. Mēnā ka tuhia ngā raraunga hua mō ia wāhi, ka taea te hanga mahere hua. He pai ēnei mahere mō te aromatawai i te whai huatanga o ngā maimoatanga whakatipu, te tautuhi i ngā wāhi he iti tonu ngā hua, me te whakawhanake i ngā rautaki whakapai ake. Ka whakamahia hoki e ētahi pūnaha ngā tauira matapae hua e whakauru ana i ngā taurangi huarere, te momo oneone, me te taupū tipu.
7. Te Whakaiti i te Mōrearea me te Huringa Āhuarangi
Ka piki ake te mōrearea o te waipuke, te tauraki, me te huarere kino i te huringa āhuarangi. Ka taea te whakamahi i te GIS hei mahere i ngā wāhi e pāngia ana e ngā āhuatanga kino, hei waihanga i ngā horopaki pānga, me te whakamahere urutau. Hei tauira, te whakatau i tētahi maramataka whakato e hangai ana ki te mōrearea āhuarangi, te whakamahere i ngā puna wai, te whiriwhiri rānei i ngā momo e tika ana mō ngā āhuatanga motuhake. I te taumata rohe, ka tautoko te GIS i ngā kāwanatanga me ngā umanga ahuwhenua ki te whakahaere i te haumarutanga kai.
Ngā Painga Ōhanga me te Taiao
He maha ngā painga o te whakamahinga o te GIS i roto i te ahuwhenua. I te taha ōhanga, ka taea e ngā kaimahi pāmu te whakaiti i ngā utu whakauru mā te tongi me te rehu kua arotahihia, te whakaiti i ngā mate nā te whakaroa o te kimi raruraru, me te whakapiki i te hua mā te whakahaere auau. I te taha taiao, ka āwhina te GIS ki te whakaiti i te rerenga tongi ki roto i ngā awa, te whakaiti i te whakamahinga o ngā patu pepeke, me te tautoko i ngā mahi tiaki oneone mā te mārama ake ki te horo me ngā pari whenua.
Ngā Wero i roto i te Whakatinanatanga
Ahakoa tōna kaha nui, ehara i te mea ngāwari te whakatinana i te GIS i ngā wā katoa. Ko ngā wero noa ko te utu o ngā taputapu me ngā raraunga, te iti o te urunga ipurangi i ngā rohe taiwhenua, te kore o ngā pūkenga tukatuka raraunga, me te hiahia ki ngā whakahoutanga raraunga auau. Hei tāpiri, ko te whakauru raraunga mai i ngā puna maha me whai paerewa raraunga pakari me te whakahaere. Ko te whakatika i tēnei me whai whakangungu, tautoko mai i ngā kaimahi toronga, me te whakamahi i ngā tūāpapa GIS tuwhera-pūtake utu nui ake, i ngā ratonga kapua rānei.
Te Katinga
Kua noho te hangarau GIS hei taputapu nui mō te huri i te ahuwhenua ki tētahi pūnaha tika ake, whai hua ake, me te pumau ake. Mā te kaha ki te mahere me te tātari i ngā raraunga e ahu mai ana i te tauwāhi, ka āwhina te GIS i ngā kaimahi pāmu ki te mārama ake i ō rātou whenua, ki te whakahaere tika i ngā whakaurunga, ki te aroturuki i te hauora o ngā hua, me te urupare wawe ki ngā mōrearea. I te heke mai, mā te whakaurunga o te GIS ki ngā waka rererangi, ngā pūoko IoT, me te mātauranga horihori ka whakapakari ake i te whakatau kaupapa e ahu mai ana i ngā raraunga. Mō te ahuwhenua o Initonīhia, ehara te tango GIS i te mea he kōwhiringa hangarau noa iho, engari he taahiraa rautaki hei whakanui ake i te hua me te tiaki i te taiao me te haumarutanga kai mō te wā roa.
