AFRICA: 1:50,000 Topographic Maps  

Africa has been, and will continue to be, an area of great interest for its history, abundant natural resources and cultural diversity.  EVG has maintained an office in Africa for over five years. This presence has allowed us establish close relationships and form agreements with national mapping agencies across Africa. This network has allowed us to acquire extensive coverage of nationally produced maps from various countries.  Most notably, we have amassed a large collection of 1:50,000 scale topographic maps over many of Africa's countries.  This is the largest scale at which most countries produce maps, and it provides excellent detail for elevation, roads, cities and much more.

Feature Country - TANZANIA
As an emerging mining destination and natural gas producer with immense infrastructural projects in tow, the Tanzanian government is opening up to investors in their efforts to boost economic growth. EVG, in partnership with Tanzania's Survey and Mapping Division, now brings you complete countrywide coverage of their nationally produced 1:50,000 scale topographic maps. Through our agreement with them, their topographic products can be offered digitally.

Feature Country - ZIMBABWE
Published by Surveyor-General Rhodesia/Zimbabwe, this map series consists of near complete country coverage of Zimbabwe with 570 of 573 maps published between 1965 and 2005. With increases of 35-50% in the mining and agriculture sectors and overall exports over the last 3-4 years, Zimbabwe's economy is now beginning to recover from more than a decade of decline. Development and growth is afoot and these maps show it all.

In addition to Zimbabwe and Tanzania, 1:50,000 scale topographic maps are available for:

Precision Aerial Imagery

RGB* Precision Aerial Imagery by County
This simple solution for county-wide RGB 30cm aerial imagery is ideally suited for county governments. For applications requiring imagery at higher resolution than is currently available from commercial satellites, aerial data is key. Using their industry-leading digital imaging technology, DigitalGlobe has acquired wall-to-wall 30cm natural color and 60cm color-infrared orthoimagery coverage of the contiguous United States and Western Europe, with 15cm resolution imagery available for Germany.

This product, Precision Aerial, is perfect for users seeking an attractively-priced imagery solution that requires no further processing or manipulation by the end-user. Precision Aerial data is collected from a uniform platform with consistency in accuracy, seasonality and resolution. 

The appetite of the geospatial industry for data with better resolution and greater consistency continues to grow. This product is ideally suited for such users and fills a commercial void in the market for high-quality digital orthophotos.  


[Sample Images 2 - 30cm RGB - 60cm CIR, California, USA]  


As a North American Partner of DigitalGlobe, East View Geospatial (EVG) is able to offer the Precision Aerial product in addition to imagery collected from DG's constellation of high-resolution satellites.

Geospatial Data & Map Services for Academia

Geospatial Data Hosting
EVG hosts terabytes of vector data, raster data and digital maps. EVG can host your existing databases, or the databases provided by EVG. The data and raster maps can be accessed through a web application for non-GIS users, and through Web Mapping Service (WMS), Web Feature Service (WFS), or Web Coverage Service (WCS) for use in GIS. These services can simply be used to view maps/data, or can be customized to query, analyze and download the maps/data.

Map Scanning, Cataloging and Indexing 
EVG maintains the world's largest commercially-available collection of maps and geospatial data. Our own digitization, cataloging, scanning, index map-creation and overall collection management procedures has proven valuable to the academic community at large. EVG has performed numerous cataloging projects, which often include custom procurements, high-resolution scanning and metadata creation for ingestion into various ILS/OPAC systems. In addition to readily available Off-The-Shelf indexes (GIS shapefiles, tabular data, or index maps), EVG can scan maps, store digital backup copies and compile series and sheet level metadata to meet custom specifications.
