Gazetteers

Gazetteers are vital tools for navigating around maps and quickly locating individual streets within cities. They can also be used to geo-code your data and create lists of places within a defined area. Gazetteers can be provided as text files, as a spread sheet or as an Access database.

There are two types of gazetteer available for Turkey:

	TR-Gaz-National	A National gazetteer listing all towns, cities and villages, together with region names and lat/long coordinates
	TR-Gaz-City	Individual gazetteers listing street name and x,y coordinates within a town or city.  Postcode information can be added as a separate option where available and if required. The cities available are listed under Street Data.

Distance Matrices

Distance Matrices are created on demand as standard tables (based on private car drive-times between postcode sector centroids) &/or as customised tables for any combination of origins and destinations within Turkey, including user-identified locations such as sales outlets, warehouses, customers or suppliers.

The standard Distance Matrix for Turkey lists distances and drive times between the administrative centres (major towns) and can be supplied as a comma delimited text file or as a spread sheet.

TR-Dist-Std

Standard Distance Matrix

In conjunction with datasets from adjacent countries, international drive-time matrices can be created on request.

Geocoding

Most forms of business, social or socio-economic analysis is based on the ability to "register" or geo-code data with respect to base maps for the area concerned.

All the data from Geo Strategies will already be geo-coded, however, there are situations where users will wish to carry out their own geocoding. In the industry, this is mainly based on postcode boundaries &/or centroids.

There are a total of 923 sub-provinces for Turkey which means that each one, on average, covers 838 sq km or has a radius of 16.3 km, and includes ~ 26,300 households. For Ankara, there are 395 sub-provinces which, on average, enclose an area with a radius of 660 m and include ~ 2,900 households.

If the postcode is known, this level of accuracy may be perfectly adequate for the majority of analyses. If, however, greater positional accuracy is required for thematic analysis or routing, then the coordinates may be deduced from a close examination of the Geo Strategies digital road maps which are accurate to ~ 30 metres.
