ETHIOPIA - 1:50K Topographic Maps

East View Cartographic's presence in Africa is becoming household.  Through the hard work of our African office in neighboring Kenya, we have procured a set of Ethiopia nationally produced 1:50,000 scale topographic maps.  This map set is ideally suited where exceptional terrain detail coverage and high contour density are necessary. 

Ethiopia 50K sample
Ethiopia 1:50,000 Topographic Map 


This elusive series consists of just shy of 1,000 maps and covers about 2/3rds of the country (coverage in green below).  The maps were incrementally published by the Ethiopian Mapping Authority between 1974 and 2002.  These very detailed maps include all typical topographic, hydrographic, land designation and cultural features including contour intervals at 10m.  The map contents and full legend are in English.

THE NETHERLANDS - Distributor agreement with the Kadaster brings Dutch topographic maps, vector data and aerial imagery to EVC 

Kadaster  Logo
East View Cartographic is now an official distributor of the Kadaster, the Netherlands (Dutch) geodata agency. 
Late last year, due in large part to our Europe office located in The Netherlands, we signed a distributor agreement with the Kadaster making us an official distributor of their geospatial data worldwide. The main objective of this agency is to collect details about registered properties in the Netherlands and record them in cadastral maps.  As a result of this mission, Kadaster has built up a large library of geospatial data for the entire country of The Netherlands that is now available to the rest of the world through EVC.

The Netherlands - 1:10,000 Vector Data


Kadaster's data is of superb quality and EVC can deliver this quickly.  The available data is topographic maps in paper and raster in scales from 1:400,000 to 1:10,000; vector data in scales of 1:10,000 and 1:25,000 and high-resolution 40cm aerial imagery.  A bulk of metadata and symbolization setups for different GIS systems are also a part of this complete package of Dutch data.

SOUTH AFRICA - 1:50K GIS Vector Data

A recent exhibition at a tradeshow in South Africa brought us an unexpected dataset, complete 1:50,000 vector coverage of the entire Republic of South Africa.  Produced by the Department of Rural Development and Land Reform, digital topographic information has been captured from the department's 1:500K and 1:50K map series.  This information has been topologically structured and stored as features (such as all roads, railways, built-up areas, rivers and contours) of the entire 1:50,000 national series (1913 sheets).

A great thing about EVC is the wide variety of clients we serve along with their wide variety of geospatial needs.  This keeps us on our toes and ready for new challenges.




1:5,000 Large-Scale Planimetric GIS Database of Taiwan with native database scripts preserved  


The ability to read a map is one thing.  The ability to read a map in another language is, well, another thing.  In fact, this "another thing" is a skill that not many cartographers possess, at least not in the U.S.  About a year ago a customer came to us with a problem.  Provided to them was a Taiwanese produced GIS database of large-scale vector data of the entire country of Taiwan (25 provinces).  Of course, in order for them to be able to use it, they needed it to be converted into English.   After proposing our solution to them, they were impressed and went for it and we delivered the product last month.


Taiwan - 5K Vector



Rarely does such a detailed and updated GIS database exist and become commercially available for an entire country.   The provision of this database demonstrates that there is a commercial demand for highly accurate and comprehensive international geospatial databases.   Data such as this has multiple uses, from improving efficiency of infrastructure development and planning, network and market analysis and risk assessment, mitigation and disaster response.



Taiwan - 5K Vector Attribute Table



From colors on paper to analytical stratigraphy, here are the steps of bringing geological raster data to metadata supported vector data:


1.  Source dataset was acquired from the supplier in ESRI shapefile format. The challenge was to make sure that native Taiwanese script is preserved in the database.


2.  Since shapefile format  does not directly support Unicode encoding (using general 8-bit DBF files) alternative data conversion methodology has had to be introduced.


3.  Solution was found using alternative open source GIS system to convert data into GML format.


4.  Final delivery has been made in ESRI file geodatabase format that supports Unicode UTF-8 encoding and is acceptable by our client.



Utilizing our geospatial skill set and toolbox to find cost-effective solutions for our clients is what we do.  We are happy to tackle new opportunities that keep us on the leading edge of the ever-changing geospatial industry.
