Raster topographic maps11/16/2023 ![]() Using various inputs such as Georeferenced raster file, Neat-line Co-ordinates, Topographic Maps etc, vector data sets are produced. ![]() Sunram has experience in the production of digital data through the capture of topographical features in the NTS dataset conforming to the standards and specifications defined in the NTDB and Data Dictionary. Next, the vector contours must be tagged with their corresponding elevation values. There is a requirement to specify the domain of attribute values for each entity and the output is produced as a. The raster elevation contours must first be converted to vectors. More than 90 of Hemas regional and four wheel drive maps which include many different areas such as Cape York, the Top End, Simpson Desert, the Pilbara, Kimberley + many more and also many National Parks. The new Australia Topo 150K, all of Australia at 150K scale. The specifications for vectorization of raster maps are exhaustive and define spatial relations between and for 112 entities and 14 themes. HEMA - Australia 4WD Raster Map Collection. Each map tile is one data set which has entity as its basic unit, and organized into 14 themes. ![]() Search Limits: The search result limit is 100 records select a Country, Feature Class, and/or Feature Type to.
