Maitiro Ekuverenga Kureba Kwenzvimbo Uchishandisa Mepu Yenzvimbo
Pendauluan
Mepu dzenzvimbo dzinobatsira zvikuru pakunzwisisa mamiriro enzvimbo. Dzinoratidza zvinhu zvakasiyana-siyana zvakaita sekukwirira, magadzirirwo enyika, nezvimwe zvinhu zvakadzama. Imwe yenzira huru dzekushandisa mepu dzenzvimbo ndeyekuverenga kukwirira kwenzvimbo chaiyo. Chinyorwa chino chichakurukura zvakadzama maitiro ekuverenga kukwirira uchishandisa mepu yenzvimbo, ichifukidza kunzwisisa kwekutanga kwemamepu enzvimbo, matanho ekuverenga magadzirirwo, uye matekiniki ekuverenga kukwirira.
Kunzwisisa Mepu dzeTopographic
Mepu yenzvimbo inomiririra pamusoro penyika, ichiratidza mitsetse yenzvimbo, kana kuti kukwirira, pamusoro pegungwa. Mamepu aya anoshandisa mitsetse yenzvimbo kubatanidza nzvimbo dzine kukwirira kwakaenzana. Mitsetse yenzvimbo iri pedyo, ndipo panonyanya kukwira mawere.
Zvinhu zveMepu yeTopographic
Usati watanga kuverenga kukwirira, zvakakosha kunzwisisa zvinhu zvakakosha zvinowanikwa pamamepu enzvimbo:
1. Mutsetse weContour: Mutsetse unobatanidza nzvimbo dzine kukwira kwakaenzana. Daro rakamira pakati pemitsara yecontour rinonzi contour interval.
2. Nguva yeContour: Musiyano wekukwirira pakati pemitsara miviri yakatevedzana yecontour.
3. Contour Index: Mitsetse yecontour inodhindwa nehupamhi hwakakora uye yakanyorwa nekukwirira kwayo kuti zvive nyore kuverenga.
4. Chikero cheMepu: Chiyero chiri pakati pedaro riri pamepu nedaro chairo riri pasi.
5. Ngano: Tsananguro yezviratidzo zvakashandiswa pamepu.
6. Kutarisa Mepu: Kazhinji kunoratidzwa nekwakananga kuchamhembe pamepu.
Matanho Ekuverenga Kureba Kwenzvimbo
Heano matanho aunogona kutevera kuti uverenge kukwirira kwenzvimbo uchishandisa mepu yenzvimbo:
1. Ziva Mitsetse yeContour uye Nguva dzeContour
Danho rekutanga nderekuona mitsetse yecontour pamepu uye kuona nguva yayo. Nguva yecontour inowanzo ratidzwa munhoroondo yemepu. Semuenzaniso, kana nguva yecontour iri mamita makumi maviri, izvi zvinoreva kuti mutsetse wega wega wecontour unomiririra shanduko yekukwirira kwemamita makumi maviri.
2. Tsvaga Nzvimbo Yenzvimbo Yaunoda Kuverenga
Tevedzera nzvimbo yaunoda kuverenga kukwirira kwayo pamepu. Iyi inogona kuva nzvimbo chaiyo kana nzvimbo yakakura. Cherechedza mitsetse yemakona yakatenderedza nzvimbo yacho.
3. Kuziva Nhamba yeContour iri Pedyo
Tsvaga mutsetse we index contour uri pedyo newe kwaunoenda. Cherechedza kuti mutsetse we index contour wakakura uye wakanyorwa ne elevation. Semuenzaniso, kana mutsetse we index contour wakanyorwa 200 metres, zvinoreva kuti mutsetse wacho uri 200 metres pamusoro pegungwa.
4. Kuverenga Nhambwe Yakamira Kubva Pamutsetse WemaContour Ari Pedyo
Mushure mekuona mutsetse wecontour index uri pedyo, verengai huwandu hwemitsara yecontour kubva panzvimbo yaunoda kuyera kukwirira kusvika kumutsetse wecontour uri pedyo. Kana nzvimbo yenyu iri pakati pemitsara miviri yecontour, muchafanira kufungidzira daro rayo zvichienderana nekusvika kwayo kumiganhu iyoyo.
5. Kuverenga Kureba
Shandisa nguva yekutarisa kukwirira. Semuenzaniso, kana nguva yekutarisa kukwirira iri mamita makumi maviri uye nzvimbo yako iri mitsetse miviri yekutarisa pamusoro pemutsetse wekutarisa wemamiriyoni mazana maviri, saka kukwirira kwenzvimbo yacho kuri 200 + (2 x 20) = mamita mazana maviri nemakumi mana.
6. Kushandisa Interpolation Kuti Uwane Kururama Kwakanyanya
Kana nzvimbo yauri kuyera iri pakati pemitsara miviri yecontour, uchafanira kushandisa interpolation kuti uwane mhedzisiro chaiyo. Semuenzaniso, kana nzvimbo yacho iri pakati pemitsara yecontour ye240-meter ne260-meter, kukwirira kwayo kunogona kufungidzirwa kuti inosvika mamita mazana maviri nemakumi mashanu.
Muenzaniso Unoshanda Wekuverenga Kureba
Ngatishandisei matanho ari pamusoro apa pamuenzaniso unoshanda. Ngatitii une mepu yeGomo A ine nzvimbo ine miganhu yemamita makumi mashanu:
1. Ziva Mitsetse yeContour uye Nguva dzeContour:
- Nguva yepakati magadzirirwo emepu Gomo A rine kukwirira kwemamita makumi mashanu.
2. Tsvaga Nzvimbo Yenzvimbo Yaunoda Kuverenga:
- Nzvimbo inofanira kuverengerwa iri panzvimbo X pamepu.
3. Kuziva Nearest Contour Index:
– Mutsetse wechiratidzo uri pedyo ndiwo mamita mazana mana.
4. Kuverenga Nhambwe Yakamira Kubva Pamutsetse WemaContour Ari Pedyo:
- Nzvimbo X imitsara miviri yecontour iri pamusoro pemutsetse we index we 400 metres.
5. Kuverenga Kureba:
– Kureba = 400 + (2 x 50) = mamita mazana mashanu.
Kana nzvimbo X iri pakati pemitsara miviri ye contour, fungidzira daro rayo uchishandisa interpolation. Semuenzaniso, kana X iri pakati chaipo pemamita mazana mana nemakumi mashanu nemamita mazana mashanu, kukwirira kwayo kunenge mamita mazana mana nemakumi manomwe nemashanu.
Zvikanganiso Zvakajairika uye Mazano Ekuverenga Mepu dzeTopographic
Zvikanganiso Zvakajairika
- Kusateerera Chikero cheMepu: Kusateerera chikero chemepu kunogona kukonzera kuverenga kusina kururama.
- Kusanzwisiswa kweMitsetse yeContour: Kufunga nezvemitsetse yese yecontour semitsetse ye index kunogona kukonzera zvikanganiso.
– Kusateerera Nguva yeContour: Kusaziva nguva yecontour kuchaita kuti kuverenga kwako kuve kusina kururama.
Mazano ekuverenga Mepu dzeTopographic
- Shandisa Zvishandiso: Kushandisa zvishandiso zvakaita serura kana kambasi yekutarisa mamiriro enzvimbo kunogona kubatsira mukuona kuti zvinhu zvakarurama.
- Dzidzira Kazhinji: Kana ukanyanya kudzidzira kuverenga mamepu enzvimbo, hunyanzvi hwako hunowedzera.
– Simbisa Mhedzisiro: Kana zvichibvira, simbisa mhedzisiro yako uchishandisa dzimwe nzira dzakadai se altimeter kana sevhisi yedhijitari yemapu.
Mhedziso
Kuverenga kukwirira uchishandisa mepu yenzvimbo kunoda kunzwisisa kwakakwana kwezvinhu zviri pamepu uye nzira dzakakodzera dzekuverenga. Nekutevera matanho ataurwa, unogona kuona zviri nyore kukwirira kwenzvimbo chaiyo. Uyezve, kudzidzira nguva dzose uye kutarisisa zvakadzama zvichabatsira kuvandudza kururama uye kushanda zvakanaka kwekuverenga nekushandisa mepu dzenzvimbo. Mepu dzenzvimbo zvishandiso zvinokosha, kwete kune vanoongorora nzvimbo nevanokwira makomo chete, asiwo kune chero munhu ari kutsvaga kunzwisisa kwakadzama kwenzvimbo nenzvimbo.
