The Survey and Mapping Office provides various types of Public Sector Information free to the general public for non-commercial and commercial use. At present, open data include geo-referenced public facility data, geodetic survey data, aerial photo flight index, digital terrain model and street name. Open maps include topographic maps (B100k-OM and B200k-OM) and orthophoto map (DOPM100-L0-OM). The topographic maps show key geographical features and are suitable for map applications in 1:100 000 and 1:200 000 scales. The orthophoto map is mosaicked from geometrically rectified aerial photographs and constructed at the scale of 1:100 000.
