The 3D model is an important resource when planning construction, height regulations and land use rulings. The model was created using photogrammetric assessment of aerial photographs taken from 2000 to 2008. The most recent update of development data took place in 2016, and terrain data in 2018. The development model is accurate to at least 0.5 m, and the terrain model to at least 1 m.</p> <p>The development model is regularly updated to ensure consistent quality.</p> <p>Data is used in various web applications and can be viewed at:  <a href="http://www.iprpraha.cz/3dmodel" target="_blank">www.iprpraha.cz/3dmodel</a>.

Potenciál využití prostorových dat je však mnohem širší, v praxi se vyskytuje celá řada úloh, ve kterých je požadováno zjištění existence prvků nebo jejich vlastností na určitém místě povrchu Země, aniž by bylo potřeba současně zobrazovat mapový výstup lokality. Pro řešení těchto úloh využívá hl. m. Praha tzv. dotazovací služby. Jedná se webové služby dle standardu XML-RPC, umožňující vyhledávat informace o de facto libovolných datech datového skladu prostorových dat.</p> 142Query services 2019-03-27T09:48:15Z Receiving geodetic documentation http://www.geoportalpraha.cz/en/clanek/187/receiving-geodetic-documentation <p>Documentation for completed building projects, especially geodetic documentation for construction (DSPS) and geometric plans, are the fundamental basis for updating the Digital Technical Map of Prague (DTMP).

Considering their success with users, it was initially decided that one quarter of the territory would be updated annually. However, the great demand for current data led to a shorter cycle and beginning in 1999, half of the territory was photographed each year. In 2007, a decision was made to photograph the entire territory annually, and currently there are flyovers twice a year.</p> 14Orthophoto maps 2019-08-07T14:42:42Z
