Ta\u010diau daugelis \u0161ali\u0173, \u012fskaitant Ukrain\u0105, susiduria su pasenusiomis \u017eem\u0117lapi\u0173 sudarymo sistemomis, kurios trukdo pa\u017eangai. Neseniai, 2025 m., paskelbtame Stadnikovo ir koleg\u0173 tyrime nagrin\u0117jama, kaip geoinformacin\u0117s technologijos (GIT) \u2013 \u012frankiai, kurie renka, analizuoja ir vizualizuoja erdvinius duomenis \u2013 gali automatizuoti skaitmenini\u0173 topografini\u0173 \u017eem\u0117lapi\u0173 k\u016brim\u0105 ir prie\u017ei\u016br\u0105.<\/p>\n

Kritinis \u0161iuolaikini\u0173 topografini\u0173 \u017eem\u0117lapi\u0173 poreikis<\/h2>\n

Topografiniai \u017eem\u0117lapiai yra daugiau nei kra\u0161tovaizd\u017eio br\u0117\u017einiai \u2013 jie yra gyvybi\u0161kai svarb\u016bs sprendim\u0173 pri\u0117mimo \u012frankiai. \u0160iuose \u017eem\u0117lapiuose naudojamos kont\u016brin\u0117s linijos, simboliai ir spalvos, kad b\u016bt\u0173 pavaizduotas auk\u0161tis, vandens telkiniai, keliai ir augmenija, taip sukuriant 3D reljefo perspektyv\u0105.<\/p>\n

Ukrainoje daugiau nei 70% \u0161i\u0173 \u017eem\u0117lapi\u0173 yra i\u0161 sovietme\u010dio ir daugiausia skirti kariniam naudojimui. \u0160iuose pasenusiuose \u017eem\u0117lapiuose tr\u016bksta detali\u0173, kurios yra labai svarbios \u0161iuolaikiniams poreikiams, pavyzd\u017eiui, \u017eem\u0117s auk\u0161\u010dio potvyni\u0173 modeliavimui ar sklyp\u0173 rib\u0173 miest\u0173 pl\u0117trai.<\/p>\n

Dar blogiau, kad per pastaruosius penkerius metus atnaujinta ma\u017eiau nei 101 TP3 TB \u017eem\u0117lapi\u0173, nepaisant teisinio reikalavimo juos per\u017ei\u016br\u0117ti kas pus\u0119 de\u0161imtme\u010dio. \u0160is v\u0117lavimas turi reali\u0173 pasekmi\u0173.<\/p>\n

Pavyzd\u017eiui, pasen\u0119 \u017eem\u0117lapiai apsunkina karo nuniokot\u0173 miest\u0173 atstatymo pastangas arba numato nuo\u0161liau\u017eas \u2013 stichines nelaimes, \u012fvykstan\u010dias, kai dirvo\u017eemis ir uolienos slysta \u0161laitais, \u2013 kurios Ukrainai kasmet kainuoja apie 1420 mln. JAV doleri\u0173 infrastrukt\u016bros \u017ealos.<\/p>\n

Tyrime pabr\u0117\u017eiama, kad \u0161i\u0173 \u017eem\u0117lapi\u0173 modernizavimas yra ne tik techninis atnaujinimas, bet ir b\u016btinyb\u0117 ekonominiam ir socialiniam stabilumui.<\/p>\n

Kas yra automatinis skaitmeninis topografinis kartografavimas\u00a0<\/strong><\/h2>\n

Automatinis skaitmeninis topografinis kartografavimas \u2013 tai pa\u017eangi\u0173 technologij\u0173 ir programin\u0117s \u012frangos sistem\u0173 naudojimas kuriant, atnaujinant ir pri\u017ei\u016brint i\u0161samius \u017dem\u0117s pavir\u0161iaus ypatybi\u0173, toki\u0173 kaip auk\u0161tis, reljefas, vandens telkiniai ir \u017emogaus sukurti dariniai, vaizdus su minimaliu \u017emogaus \u012fsiki\u0161imu.<\/p>\n

Skirtingai nuo tradicini\u0173 metod\u0173, kurie remiasi rankiniu matavimu ir brai\u017eymu, ADTM naudoja pa\u017eangias technologijas, tokias kaip geografin\u0117s informacin\u0117s sistemos (GIS), dronai, LiDAR (\u0161viesos aptikimas ir diapazono nustatymas), palydoviniai vaizdai ir dirbtinis intelektas (DI), kad sukurt\u0173 labai tikslius, dinami\u0161kus ir kei\u010diamo dyd\u017eio \u017eem\u0117lapius su minimaliu \u017emogaus \u012fsiki\u0161imu.<\/p>\n

\"Kas<\/p>\n

\u0160is metodas kei\u010dia tokias pramon\u0117s \u0161akas kaip miest\u0173 planavimas, \u017eem\u0117s \u016bkis, nelaimi\u0173 valdymas ir nacionalinis saugumas. Pavyzd\u017eiui, 2023 m. Pasaulio banko ataskaitoje apskai\u010diuota, kad \u0161alys, diegian\u010dios ADTM, suma\u017eino \u017eem\u0117lapi\u0173 atnaujinimo i\u0161laidas 40\u201360% ir pagreitino projekt\u0173 terminus 70%, palyginti su rankiniais metodais.<\/p>\n

Ukrainoje, kur daugiau nei 70% topografini\u0173 \u017eem\u0117lapi\u0173 yra pasen\u0119, ADTM laikoma svarbia priemone pokario atstatymui ir ekonomikos atsigavimui.<\/p>\n

Kaip veikia geografin\u0117s informacin\u0117s sistemos (GIS)<\/h2>\n

\u0160iuolaikin\u0117s kartografijos \u2013 \u017eem\u0117lapi\u0173 sudarymo mokslo ir meno \u2013 pagrindas yra geografin\u0117s informacin\u0117s sistemos (GIS). \u0160ios sistemos apjungia technin\u0119 ir programin\u0119 \u012frang\u0105, duomenis ir metodus erdvinei informacijai, t. y. su geografin\u0117mis vietov\u0117mis susijusiems duomenims apdoroti. Tyrime GIS suskirstoma \u012f keturias pagrindines dalis.<\/p>\n

    \n
  1. Pirmas<\/strong>, Neapdorotus duomenis renka tokia \u012franga kaip dronai (bepilot\u0117s orlaiviai arba UAV), palydovai ir didel\u0117s skiriamosios gebos skeneriai. Pavyzd\u017eiui, dronai gali u\u017efiksuoti i\u0161samius kra\u0161tovaizd\u017eio vaizdus u\u017e nedidel\u0119 dal\u012f tradicini\u0173 metod\u0173 kainos.<\/li>\n
  2. Antra<\/strong>, Tokia programin\u0117 \u012franga kaip \u201eArcGIS\u201c (auk\u0161\u010diausios kokyb\u0117s \u012frankis sud\u0117tingam modeliavimui) arba \u201eQGIS\u201c (nemokama, atvirojo kodo alternatyva) apdoroja \u0161iuos duomenis, paversdama vaizdus redaguojamais \u017eem\u0117lapiais.<\/li>\n
  3. Tre\u010dias<\/strong>, patys duomenys apima erdvines detales, tokias kaip koordinat\u0117s ir auk\u0161\u010diai, taip pat atribut\u0173 informacij\u0105 \u2013 apra\u0161omuosius duomenis, tokius kaip \u017eem\u0117s naudojimas, gyventoj\u0173 tankumas ar dirvo\u017eemio tipas.<\/li>\n
  4. Galiausiai<\/strong>, Tokios metodologijos kaip vektorizavimas \u2013 rastrini\u0173 vaizd\u0173 (pikseli\u0173 pagrindu sukurt\u0173 format\u0173, pvz., JPEG) konvertavimo \u012f vektorinius formatus (redaguojamus kelius ir formas) ir erdvin\u0117 analiz\u0117 automatizuoja u\u017eduotis, kurioms anks\u010diau reik\u0117jo rankinio darbo. Kartu \u0161ie komponentai leid\u017eia grei\u010diau ir tiksliau sudaryti \u017eem\u0117lapius.<\/li>\n<\/ol>\n

    Teisini\u0173 ir technologini\u0173 kli\u016b\u010di\u0173 \u017eem\u0117lapi\u0173 sudarymo \u012fveikimas<\/h2>\n

    Ukrainos kelias link modernaus kartografijos yra kupinas i\u0161\u0161\u016bki\u0173. Grie\u017eti \u012fstatymai, tokie kaip 1998 m.\u00a0Topografin\u0117s-geodezin\u0117s ir kartografin\u0117s veiklos \u012fstatymas<\/em>\u2013 \u017eem\u0117lapi\u0173 k\u016brim\u0105 ir atnaujinim\u0105 reglamentuojantis reglamentas \u2013 reikalauja, kad visi \u017eem\u0117lapi\u0173 sudarymo darbai b\u016bt\u0173 registruojami Ukrainos nacionalin\u0117je geoprini\u0173 duomen\u0173 institucijoje \u201eStateGeoCadastre\u201c.<\/p>\n

    Nors tai u\u017etikrina kokyb\u0117s kontrol\u0119, kartu atsiranda ir biurokratini\u0173 v\u0117lavim\u0173. Nuo 2022 m. \u012fvesta karo pad\u0117tis dar labiau apsunkino proces\u0105: aerofotografavimui dabar reikalingi Ukrainos saugumo tarnybos leidimai, o \u0161is procesas gali u\u017etrukti nuo trij\u0173 iki \u0161e\u0161i\u0173 m\u0117nesi\u0173.<\/p>\n

    Be to, prieiga prie Nacionalin\u0117s geoprini\u0173 duomen\u0173 infrastrukt\u016bros geoportal\u0173 \u2013 internetini\u0173 platform\u0173, kuriose talpinami \u017eem\u0117lapiai ir erdvini\u0173 duomen\u0173 rinkiniai \u2013 yra ribojama tik patvirtintiems vartotojams, tod\u0117l visuomen\u0117s dalyvavimas yra ribojamas.<\/p>\n

    Technologij\u0173 srityje vyriausybin\u0117s agent\u016bros da\u017enai naudoja nesuderinam\u0105 programin\u0119 \u012frang\u0105 ir klasifikavimo sistemas. Pavyzd\u017eiui, viena agent\u016bra gali naudoti \u201eArcGIS\u201c, o kita \u2013 \u201eAutoCAD Map\u201c, tod\u0117l dubliuojami 30% duomenys ir \u0161vaistomi i\u0161tekliai.<\/p>\n

    D\u0117l \u0161io susiskaidymo Ukraina kasmet kainuoja apie 14,5 mln. JAV doleri\u0173 d\u0117l nereikaling\u0173 lauko tyrim\u0173, kai t\u0105 pa\u010di\u0105 teritorij\u0105 kelis kartus tiria skirtingos komandos.<\/p>\n

    Dronai, kei\u010diantys topografini\u0173 duomen\u0173 rinkim\u0105<\/strong><\/h2>\n

    Vienas i\u0161 perspektyviausi\u0173 tyrimo rezultat\u0173 yra dron\u0173, arba bepilo\u010di\u0173 orlaivi\u0173 (UAV), naudojimas duomenims rinkti. UAV yra nuotoliniu b\u016bdu valdomi orlaiviai, kuriuose \u012frengtos kameros arba jutikliai.<\/p>\n

    Tradiciniai metodai, tokie kaip palydovin\u0117s nuotraukos, kainuoja nuo\u00a0500 ir <\/span><\/span>1000 kvadratiniame kilometre, ta\u010diau dronai gali pasiekti pana\u0161i\u0173 rezultat\u0173 vos u\u017e\u00a050 <\/span>t<\/span>o <\/span><\/span><\/span><\/span>100. Kai kurios pagrindin\u0117s i\u0161vados:<\/p>\n

      \n
    • Optimalus vaizdo persidengimas<\/strong>Lopes Bento ir kt. (2022 m.) nustat\u0117, kad 70% \u0161oninis ir 50% priekinis persidengimas dron\u0173 skryd\u017eiuose i\u0161laiko tikslum\u0105, tuo pa\u010diu sutrumpinant skryd\u017eio laik\u0105 40%.<\/li>\n
    • \u012estri\u017ea fotografija<\/strong>Cheng ir Matsuoka (2021) parod\u0117, kad vertikali\u0173 ir 45 laipsni\u0173 kampuot\u0173 vaizd\u0173 derinimas pagerina nuo\u017eulnaus reljefo 3D modeliavim\u0105, suma\u017eindamas auk\u0161\u010dio paklaidas iki <1 metro.<\/li>\n<\/ul>\n

      Nepaisant \u0161i\u0173 privalum\u0173, dron\u0173 naudojimas Ukrainoje i\u0161lieka ribotas. 2023 m. tik 15% savivaldybi\u0173 tur\u0117jo leidimus atlikti tyrimus bepilo\u010diais orlaiviais, daugiausia d\u0117l karo meto oro erdv\u0117s apribojim\u0173. I\u0161pl\u0117sus prieig\u0105 prie dron\u0173 b\u016bt\u0173 galima sutaupyti milijonus ir paspartinti \u017eem\u0117lapi\u0173 atnaujinimus.<\/p>\n

      \u017dem\u0117lapi\u0173 automatizavimas siekiant suma\u017einti klaidas<\/h2>\n

      Automatizavimas \u2013 technologij\u0173 naudojimas u\u017eduotims atlikti su minimaliu \u017emogaus \u012fsiki\u0161imu \u2013 yra pagrindinis tyrimo rekomendacij\u0173 akmuo. Skaitmeninant \u017eem\u0117lapius 4800 dpi (ta\u0161k\u0173 colyje) skaitytuvais, i\u0161saugomos net ir ma\u017eiausios detal\u0117s, tokios kaip kont\u016brin\u0117s linijos (linijos, jungian\u010dios vienodo auk\u0161\u010dio ta\u0161kus) ar nuosavyb\u0117s ribos.<\/p>\n

      Suskaitmeninta GIS programin\u0117 \u012franga gali aptikti nauj\u0173 aerofotonuotrauk\u0173 pakeitimus ir atnaujinti duomen\u0173 bazes realiuoju laiku. Pavyzd\u017eiui, drono nuotraukoje pasteb\u0117tas naujas pastatas gali b\u016bti \u012ftrauktas \u012f \u017eem\u0117lap\u012f per kelias valandas, o anks\u010diau tai u\u017etrukdavo savaites.<\/p>\n

      \"\u017dem\u0117lapi\u0173<\/p>\n

      Erdvin\u0117s analiz\u0117s \u012frankiai dar labiau padidina tikslum\u0105, apskai\u010diuodami tokias rizikas kaip potvyniai ar nuo\u0161liau\u017eos 95% tikslumu, palyginti su 75% rankiniuose metoduose. \u0160ie \u012frankiai naudoja algoritmus scenarijams, pavyzd\u017eiui, kaip vanduo gali tek\u0117ti smarkaus lietaus metu, imituoti.<\/p>\n

      Bandomasis projektas Odesoje pademonstravo \u0161iuos privalumus: automatizuotas vektorizavimas \u2013 nuskaityt\u0173 \u017eem\u0117lapi\u0173 konvertavimas \u012f redaguojamus vektorinius sluoksnius \u2013 suma\u017eino darbo s\u0105naudas 1 TP4 12 000 pes\u0173 vienam \u017eem\u0117lapio lapui, tuo pa\u010diu pagerindamas detalum\u0105.

      \u012eg\u016bd\u017ei\u0173 sprag\u0173 kartografijoje u\u017epildymas<\/h2>\n

      Reik\u0161minga modernizavimo kli\u016btis yra apmokyto personalo tr\u016bkumas. Ukrainos kartograf\u0173 apklausa parod\u0117, kad 65% tr\u016bksta pa\u017eangi\u0173 GIS mokym\u0173, tod\u0117l daugelis yra priversti pasikliauti pasenusiais \u012frankiais, tokiais kaip\u00a0Pasaulinis \u017eem\u0117lapi\u0173 sudarytojas<\/em>, pagrindin\u0117 GIS programin\u0117 \u012franga.<\/p>\n

      Siekiant u\u017epildyti \u0161i\u0105 sprag\u0105, tyrime si\u016blomos sertifikavimo programos ir seminarai. Partneryst\u0117 su universitetais siekiant pasi\u016blyti GIS kursus gal\u0117t\u0173 atspind\u0117ti s\u0117kmingus modelius, tokius kaip JAV GIS specialisto (GISP) sertifikavimas \u2013 kvalifikacij\u0105 patvirtinantis erdvini\u0173 duomen\u0173 valdymo kompetencijos pa\u017eym\u0117jimas.<\/p>\n

      Praktiniai mokymai naudojant nemokam\u0105, atvirojo kodo programin\u0119 \u012frang\u0105, toki\u0105 kaip QGIS (Quantum GIS), padaryt\u0173 \u0161iuos \u012fg\u016bd\u017eius prieinamus daugiau \u017emoni\u0173.<\/p>\n

      Uzbekistano patirtis yra pavyzdys: \u012fgyvendinusi pana\u0161ias mokymo programas, \u0161alis per dvejus metus padidino \u017eem\u0117lapi\u0173 atnaujinimo efektyvum\u0105 50%.

      Be to, verting\u0173 pamok\u0173 suteikia Ukrainos bendradarbiavimas su Norvegijos kartografijos tarnyba nuo 2018 iki 2021 m. \u012egyvendinant 8 mln. eur\u0173 kainavus\u012f projekt\u0105, buvo atnaujinti 1:50 000 mastelio nacionaliniai \u017eem\u0117lapiai, naudojant NATO standartinius simbolius ir centralizuot\u0105 debesijos duomen\u0173 baz\u0119.<\/p>\n

      1:50 000 mastelis rei\u0161kia, kad vienas vienetas \u017eem\u0117lapyje atitinka 50 000 vienet\u0173 ant \u017eem\u0117s, tod\u0117l u\u017etikrinama detalumo ir apr\u0117pties pusiausvyra.
