Location Map EASTERN TOPOGRAPHICS (E-TOPO) is a full service aerial mapping firm based in the Lakes Region Area of New Hampshire that has been providing high quality accurate mapping for engineering consultants throughout the New England area for the past thirty (30) years. Our flight crew has logged several thousand hours of cartographic aerial mapping in the difficult terrain and climatic conditions often encountered in the New England region. Our stereoplotter operators and mapping technicians are intimately familiar with the topography, ground surface conditions, foliage, and cultural features including man-made stone walls as found in the northeastern United States. We have extensive experience specific to aerial photography and digital photogrammetric mapping. Eastern Topographics' existing library of low altitude aerial photography continues to be a reliable source for accurate mapping at any time of year. We only capture cartographic imagery for our library during optimum spring conditions of complete defoliation and high sun angle. To plan for a custom flight or access our library for imagery or mapping purposes, please transmit via email, FAX, or mail a copy of a USGS quadrangle, Tax Map, or similar, outlining your area of interest. Include your desired map scale, contour interval and digital format for a cost proposal.
