Jaroslav Poláček

MapTiler

Jaroslav Poláček works at MapTiler, the Swiss mapping platform for developers, and first attended INTERGEO 14 years before the 2026 show. Recorded live at INTERGEO 2026, Jaroslav Poláček explained how developers put Gaussian splat models on web maps and why centimeter accuracy matters less there.

Questions Jaroslav answered

Can you put Gaussian splats on a web map?
Yes, according to Jaroslav Poláček: MapTiler customers place Gaussian splat models from drone imagery on top of a satellite base map, for example for hotels and real estate websites. ▶ 4:09
How do you georeference a Gaussian splat in MapTiler?
According to Jaroslav Poláček, users search the location in MapTiler's 3D editor, adjust the scale, and the model is placed on the terrain; it is done visually, without centimeter accuracy. ▶ 8:06
How does MapTiler stream large Gaussian splat models?
According to Jaroslav Poláček, every uploaded PLY gets LODs, web optimization and a streaming format, so at the lowest level only 0.05% of the data reaches the device. ▶ 10:19
Why choose MapTiler instead of Google or Apple Maps?
According to Jaroslav Poláček, the technology is similar for developers; customers notice the price and a human technical support team. ▶ 13:23
Can other MapTiler users see the data I upload?
No, according to Jaroslav Poláček: uploaded data remains the customer's own, only they can build map applications on it, and there is no marketplace for sharing data sets. ▶ 7:05
