NAVMap Raster data sets
NAVIGATE has has the ability to create coverages of raster maps that are generated from our NAVMap global vector map products using the advanced cartography ability of ArcGIS. The advantage of this approach is the flexibility and extensibility for the customer’s benefit. If required, NAVIGATE has the ability to further customise many aspects of the final product to the customer’s specific requirements.
NAVIGATE has created the dataset with its own cartographic style and content. However, any aspect of the cartography can be flexible if a customer needs their own specific style.
Colours, fonts, line styles, label behaviour and other aspects of symbology can be adjusted within the capabilities of ArcGIS and the underlying data.
Content and Extent
The data that underpins the raster datasets is NAVIGATE’s NAVMap product. There are many attributes embedded into the road vector data beyond the basic name and hierarchy codes. One-way streets, roundabouts, traffic lights, address numbers Etc are all built into the data and are included on the map. There are other road attributes that could be integrated in the future including paved/nonpaved road status, restricted access (eg emergency vehicles only), level crossings, road dividers and divider type, gates with access restrictions Etc.
NAVIGATE has access to NAVTEQ's global datasets so we can produce consistent raster data coverages for many parts of the world. See sample generated for the central part of Jakarta.
A vast amount of Points of Interest are available including community facilities such as medical centres, police and petrol stations. It is also possible in some cases to represent points of interest as highlighted cadastral parcels to de-clutter the map.
NAVIGATE can also offer to integrate additional datasets that may be supplied by other data providers or perhaps a customer may have some of its own data that it wishes to integrate into the raster datasets.
The raster data products are derived from NAVIGATE’s NAVMap vector products so if a customer have a future need to upgrade to use vector data in their GIS, there will be full and seamless compatibility.
Coverage at Different Scales
Currently there is a baseline coverage of raster maps at 1:12,500 scale for all the “Built-up” areas as defined by the NAVTEQ data. This is a set of polygons that cover city and significant towns. There will also be a complete coverage of raster maps at a scale of 1:100,000 included in the baseline coverage.
Additional and alternative coverages and scale options may be added in the future.
