LandInfo Worldwide Mapping: topographic maps of Greece: 1:250,000


Received from LandInfo Worldwide Mapping, on June 24, 2011, two sets of 34 Joint Operation Graphic (JOG) maps of Greece, with accompanying index. 

JOG topographic maps are a worldwide series produced by National Geospatial-Intelligence Agency (NGA), U.S. military mapping agency, Defense Mapping Agency (DMA), and National Imagery and Mapping Agency (NIMA). These maps have all of the standard topographic information; contours, power lines, roads, culture, etc. Some also have aeronautical information overlaid on the topographic map. The JOG series is the U.S. equivalent to the Soviet military series at 1:200,000.

The first set consists of 30 full scanned maps which includes the border and legend (non-georeferenced), with index.  Maps NK 35-7b, NK 35-10b, NJ 35-2, NJ-35-15 are not included with this set, but are included with the georeferenced and cropped set.

Spatial reference and data type

The cropped and georeferenced data sets are available in geographic co-ordinates; horizontal datum is World Geodetic System 1984 (WGS84). Data files are in TFW (tif World File) format with average file size of 40 MB.

The non-georeferenced data files are in tif format with average file size of 60 MB. Other data formats can be accommodated, as the Geospatial Centre has access to a number of conversion utilities. 

Data access
