The Area of Interest
Considered one of the seven forgotten wonders of the world, Niagara Falls is a breathtaking tourist destination. Located on the Niagara River, it acts as an international water barrier separating the United States from Canada. It is composed of two major sections, the Horseshoe Falls on the Canadian side, and the American Falls on the U.S. side. These two sections are separated by Goat Island, a popular destination on the American side accessible by foot, car or trackless train. It derives its name from a herd of goats that was kept on the island in the late 1700s, but due to an extremely harsh winter, only one goat survived. Also included in Niagara Falls is another smaller waterfall called Bridal Veil Falls. At its base is the Cave of the Winds which provides a protective barrier from the runoff - and is a very kitschy place for people to get married – hence its name. The name Niagara is believed to be derived from “Niagagarega” who were a local branch of the Iroquois Nation that resided in the area when French settlers arrived in the 1700s.

Monthly Update on DigitalGlobe's Aerial Imagery Program
eMap is pleased to be an approved reseller of the DigitalGlobe Aerial Imagery Program which will provide geospatial users with the first ever complete 1-foot aerial imagery collection over the continental US and Western Europe. The regularly updated data included in the DG Aerial Imagery Program is obtained and processed in one-degree by one-degree (lat/long) cells to the following specifications:
In this regular feature, eMap will provide updates to this coverage map as well as any other new items related to the DG Aerial Imagery Program. Since our update on the program in the July edition of GeoView, 213,000 sq km of coverage over Western Europe and 523,000 sq km of coverage over the United States has been added to the database.
- 30-cm (1-foot ) resolution
- Seamless and color-balanced
- Orthorectified with 2.6 to 5.2-m horizontal accuracy (CE90%)
- Cloud-free over urban areas and minimal to cloud-free in rural areas
- Delivered in GeoTIFF format
A US and Europe coverage map of the completed one-degree cells and those that are in progress can be found below. Also included on these maps are the urban and tourism centers that have been completed; these areas will be updated more frequently than areas considered rural.
