Department's products

  • Topographic maps :
  • This kind of maps contains contour lines, triangulation points, fixed three-coordinate known landmarks and elevation points which present the relief of specific plain. The contour lines distances are different according to maps scales and data sources . These maps also clarify the names and the geomorphologic features' shapes such as rivers, lakes, canals and drains and manmade features such as roads, railway lines inhabitation blocks and borders. There are different scales for these maps gradually from 1:1000 to 1:2 000,000 .

  • Imaged vertical maps:
  • This kind of maps is produced with 1:10,000 scale from the photogrammetric images and corrected by removing the distortions caused by inclination, elevation of sea level or by the lenses deviation while taking photos. This correction is implemented by mathematical ways via computers to get a high accuracy to equalize them with the other kinds of previous maps. This kind also clarifies the visible features and makes them clear on images, produced in paper printed maps and digital maps.

  • Tourist maps :
  • This kind of maps is produced in scales 10,000 and 15.000 to bring out touristy places and utilities which serve tourism such as embassies, consulates, hotels, restaurants and other touristy places.
    These maps are available for some cities such as Cairo, Alexandria, Hurghada, Luxor, Aswan, Port Said, Ismailia and Marsa Alam in addition to Egypt maps with scale 1:2 000,000 and Cairo streets book produced in 2009 and Ismailia book 2010.
