Konferencia sa uskutočnila v dňoch 19. – 20. marca 2024 a opäť ukázala, že komunita má čo povedať. bola výborná a účastníkov pozitívne. V priebehu dvoch dní zazneli inšpiratívne , ktoré pokryli široké spektrum tém – od praktických aplikácií, cez a , až po a technologické . Program bol pestrý. Niektoré tematicky nadväzovali, iné priniesli pohľad z úplne iného uhla. Objavila sa urbanisticko-prognostická reflexia, ekonomický aspekt s údajmi, ako aj manažérsky pohľad v území. Technologicky veľmi silný bol vstup z Prahy, ktorý zaujal svojou odbornosťou aj precíznou realizáciou.

Téma otvorených dát bola prítomná v rôznych formách a prepojeniach, čo len potvrdzuje, že ide o oblasť, ktorá v našich podmienkach dozrieva a zároveň otvára . Zvlášť zaujímavým výstupom boli tri environmentálne ladené príspevky, ktoré odštartovali veľmi konštruktívny dialóg. Aj vďaka nim sa črtá potenciál pre bližšiu spoluprácu medzi mestom a Prírodovedeckou fakultou UK. Zastúpené boli príspevky z rôznych lokalít – Bratislava, , Brno, , , , ako aj ďalšie Slovenskej a Českej republiky. boli živé a často pokračovali aj mimo hlavného programu – čo je vždy dobré znamenie. Platformu Zoom si zvolili zámerne a opäť sa ukázala ako spoľahlivé riešenie pre online podujatie tohto typu. Do budúcna však veríme, že sa nám podarí vytvoriť aj pre osobné stretnutie.

The conference took place on 19–20, 2024, and once again demonstrated that the GIS community has much to say. The atmosphere was excellent and participant feedback was very positive. Over the course of two days, inspiring presentations were delivered, covering a broad range of topics — from practical applications and urbanism to management, , and technological innovation. The program was diverse: some presentations followed thematically, while others offered perspectives from entirely different angles. Urban–prognostic reflections emerged, alongside the economic aspects of working with data and managerial perspectives on spatial decision-making. From a technological standpoint, a particularly strong contribution came from , impressing the audience with both its expertise and precise implementation.

The topic of open data appeared in various forms and connections, further confirming that this field is maturing under local conditions while simultaneously opening up new opportunities. Especially noteworthy were three environmentally focused presentations, which initiated a very constructive dialogue. Thanks in part to these contributions, there is emerging potential for closer cooperation between the of Bratislava and the Faculty of Natural Sciences of Comenius University. Contributions represented a wide range of locations — Bratislava, Prague, , Ostrava, Jihlava, the Region, as well as other regions of and the Republic. Discussions were lively and often continued beyond the main program, which is always a good sign. The Zoom platform was deliberately chosen and once again proved to be a reliable solution for an online event of this type. Looking ahead, however, we hope to create space for in-person meetings as well.

GIS Slovakia 2023

Hits: 45

V roku 2023 som usporiadal prvý ročník podujatia , ktorý sa konal formou . Tu je z neho výstup.


Konferencia, ktorá prebehla v dňoch 21. až 23. marca 2023, privítala viac než 150 účastníkov. V priebehu troch dní zaznamenali kumulovaný čas sledovania takmer 67 dní, pričom v najsilnejšom okamihu sa online stretlo až 72 ľudí naraz. Medzi prítomnými boli z rôznych úrovní , štátnych inštitúcií, akademickej sféry aj súkromného sektora. Menovite: , Metropolitný inštitút Bratislavy (), , mestské časti a , Bratislavský a Košický samosprávny kraj, SR, a Košice, , a viaceré – SPU v Nitre, UK , , , Univerzita Palackého Olomouc. Zastúpenie mal aj výskum a súkromný sektor: , Telekom, ArcGEO, Eurosense, YMS, Asseco Central , OEL-Solutions, . Celkovo bolo prezentovaných 27 príspevkov, ktoré sa snažili sprostredkovať užitočné a praktické informácie o GIS technológiách aj pre neodbornú .

Zámerom bolo nielen prezentovať výsledky , ale aj priblížiť GIS ako nástroj, ktorý prepája ľudí naprieč sektormí – od samosprávy cez akademickú pôdu až po komerčnú sféru. Ukázať, že práve táto rozmanitosť prináša hodnotu. Nejde o to, aký používame, ale aký postoj zaujímame – ku spolupráci, k otvorenosti a k spoločnému územnému vnímaniu.

Ako niekto, kto venuje mestu Bratislava už takmer 25 rokov, mi záleží na tom, aby sa GIS rozvíjal aj v tomto kontexte. Preto bolo prirodzené, že viaceré boli tematicky späté s Bratislavou – či už zo strany mojich kolegov, alebo spolupracujúcich odborníkov z blízkych oblastí. Územné témy, ktoré riešime – nielen v Bratislave, ale aj v Košiciach, Ostrave či Olomouci – majú často spoločný základ. Týkajú sa kompetencií, regiónov, potrieb aj výziev. V mnohých prípadoch presahujú úroveň mesta a smerujú ku celoslovenským, ba až globálnym otázkam – ako je klimatická zmena či adaptácia mestského .

Ďakujem veľmi pekne všetkým prezentujúcim za ich čas, energiu a ochotu zdieľať. Aj vďaka nim sa darí formovať GIS komunitu, ktorá nie je len technologická, ale najmä ľudská a hodnotová.

Príspevky


In 2023, I organized the edition of the event, held as an online conference. Below is its outcome.

The conference, which took place from 21 to 23, 2023, welcomed more than 150 participants. Over the three days, we recorded a cumulative viewing time of almost 67 days, with a peak of up to 72 people connected online at the same time. Participants included representatives from various levels of local government, state institutions, academia, and the private sector. Specifically: the Hall of the Capital City of Bratislava, the Metropolitan Institute of Bratislava (MIB), Marianum, the city districts of Staré and Ružinov, the Bratislava and Košice Self-Governing Regions, the Ministry of Environment of the Slovak Republic, the cities of Trenčín and Košice, MAPPA , and several universities — the Slovak University of Agriculture in , Comenius University in Bratislava, University in Prešov, Masaryk University in Brno, and Palacký University in Olomouc. Research and the private sector were also represented: the Transport Research Centre Brno, Telekom, ArcGEO, Eurosense, YMS, Asseco Central Europe, OEL-Solutions, and GIS Services . In total, 27 presentations were delivered, aiming to provide useful and practical information about GIS technologies even for a non-expert audience.

The goal was not only to present the results of work, but also to introduce GIS as a tool that connects people across sectors — from local government and academia to the commercial sphere. To show that this diversity itself creates value. It is not about which software we use, but about the attitude we adopt — toward cooperation, openness, and a shared spatial perspective.

As someone who has been devoted to the city of Bratislava for nearly 25 years, it matters to me that GIS continues to develop in this broader context. It was therefore natural that many of the presentations were thematically linked to Bratislava — whether from my colleagues or from collaborating experts in related fields. The spatial issues we deal with — not only in Bratislava, but also in Košice, Ostrava, or Olomouc — often share a common foundation. They concern competencies, regions, needs, and challenges. In many cases, they go beyond the level of individual cities and move toward national and even global questions — such as climate change and urban adaptation.

I would like to sincerely thank all the presenters for their time, energy, and willingness to share. Thanks to them, a GIS community is being formed that is not only technological, but above all human and value-driven.

V Žiline ZO Akvafit začala v decembri 2009 organizovať vždy každú prvú nedeľu v mesiaci v Dome ulici Vysokoškolákov, akvaristickú burzu. Akcia sa koná spolu s vtáčkarskou (exotárskou) burzou, ktorá sa koná už dlhé roky. Prvá akcia sa konala 6.12.2009 od 6:30 do 11:30. Exotárska časť vtedy skončila 9:30, ako býva zvykom. Aj mňa zaskočilo, že sa konajú v nedeľu a ešte k tomu tak skoro ráno. Čudoval som sa, aj keď som vedel, že exotári to tak majú vo zvyku aj v iným mestách Slovenska. My sa na prvú burzu vybrali štyria z Bratislavy v dvoch autách. Jeden z nás dokonca ani nebral žiadny tovar. Aj my ostatní sme šli skôr naľahko oťukať . Okrem nás prišli aj Ostraváci, , iní Bratislavčania a nejakí domáci. Veľmi sa nám páčili stoly, ktoré boli pevné a aj pekné. Páčilo sa nám aj množstvo ľudí, ktoré prišlo. Odhadujem viac ako 500 ľudí. My sme dorazili asi 5:45 na miesto a už sa aj trúsili pomedzi nás aj prví . O siedmej hodine ráno tam bol nával. Po deviatej začalo ľudí evidentne ubúdať. Akvaristov prišlo samozrejme pomenej, ale to sa dalo očakávať. Exotári však neohrdli a popozerali aj našu ponuku a podaktorí utratili aj dáke euryčká. Ja som zase rád popozeral ich , ale eurá som minul iba na párky a kofolu v miestnom pridruženom „bufete„. Bufet bol zaujímavý – promptný, sympatický personál, predával sa aj . Snáď sa ho nik nenapil ;-). Akvaristická časť ponúkala , , , , suché, živé, mrazené. Najmä mrazené krmivo bol výborný tovar, plné auto ktorým ho istý doniesol, ostalo skoro prázdne. Mrazené ponúkali aj Ostraváci, okrem toho mali živé , , , dafnie aj mikry. Po akcii sme sa premiestnili tuším štyrmi autami ku Jankovi Budaiovi, kde nám ukázal jeho klenoty. Po odchode od Jana sme nabrali kurz .

Medzitým sa konalo už množstvo týchto búrz. na ne neboli vždy len pozitívne. Pikošky, ktoré šli v Bratislave, v Žiline nechcel skoro nikto. Druhá takáto spoločná exotársko-akvaristická akcia bola 3.1.2010, čo je z môjho pohľadu hrozný termín. Napriek tomu prebehla ku spokojnosti všetkých :-)). Každopádne si myslím, takéto akcie sa nám páčili po každej stránke. Vďaka tradícii exotárov a pravidelnosti budú pre nás prínosom. Myslím samozrejme aj na pozíciu predajcov aj zákazníkov. Samozrejmé je aj to, že exotárov a akvaristov sa prelínajú aj odlišujú. Ich motivácia chovať aj kupovať je podobná. Teším sa preto na ďalšie akcie.


In , the Zoological Organization Akvafit started organizing an aquarium market every Sunday of the month at the House of Technology on Vysokoškolákov Street in December 2009. The event is held together with an exotic bird market, which has been taking place for many years. The first event took place on December 6, 2009, from 6:30 to 11:30. The exotic part ended at 9:30, as is customary. I was surprised that the events take place on Sundays and so early in the morning, although I knew that exotic enthusiasts have this habit in other cities in .

Four of us from Bratislava attended the first market in two cars. One of us didn’t even bring any goods; we were there to explore the terrain lightly. Besides us, participants came from , , other Bratislavans, and some locals. We liked the sturdy and -looking tables and were impressed by the number of people attending. I estimate more than 500 people were present. We arrived around 5:45 am, and the first customers were already mingling among us. By 7 am, there was a rush, and after 9 am, the number of people started to decrease. Naturally, fewer aquarium enthusiasts attended, but that was expected. Exotic bird enthusiasts also explored our offerings, and some spent a few euros. I enjoyed looking at their birds, but I only spent money on hot dogs and cola at the local „buffet,“ which was interesting – prompt service, friendly staff, and they even sold PMDD. Hopefully, no one drank ;-). The aquarium section offered fish, plants, shrimp, snails, and various types of dry, live, and frozen feeds. Especially the frozen feed was excellent; a full car brought by a certain Pole was almost empty by the end. The Ostrava participants also offered frozen goods, along with live killifish, , loaches, , and brine shrimp.

After the event, we moved with about four cars to Janko Budaio’s place, where he showed us his treasures. After leaving Janko’s, we set course for Bratislava. Meanwhile, several such markets have taken place. Reactions to them were not always positive. Trinkets that sold well in Bratislava were not desired in Žilina. The second joint exotic-aquarium event was on January 3, 2010, which, from my perspective, was a terrible date. Nevertheless, it went well to everyone’s satisfaction. In any case, we liked such events from every aspect. Thanks to the tradition of exotic enthusiasts and the regularity, they will be beneficial for us. I also think about the position of both sellers and customers. It’s evident that the interests of exotic enthusiasts and aquarium enthusiasts overlap and differ. Their motivation to breed and buy is similar. I look forward to future events.
