Google Earth is a web and computer program that renders a 3D representation of Earth based primarily on satellite imagery.The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles.
Tomnod used online map interfaces that engage many people to each view and tag a small section of a large area on the planet. In 2011 Tomnod cooperated with the UNHCR to locate refugee camps in Somalia. [8] Users were asked to use satellite images to count the shelters of refugees.
For photo interpretation, it is preferred that the image is taken so that the shadows can be clearly observed [2] as shadows can highlight the relief of the topography. [2] This orientation of the image also helps geologists link the 3D pictures to what they observe. [2] Figure 10: This diagram shows the position of the Sun (south).
The digital vector geographical database of the Czech Republic ArcČR® 500 is created in the detail of the scale 1: 500 000. Its content is clear geographical information about the Czech Republic. The data were created in cooperation with ARCDATA PRAHA, s.r.o., the Surveying and Mapping Authority and the Czech Statistical Office and are ...
Therefore, an image from one satellite will be equivalent to an image from any of the other four, allowing for a large amount of imagery to be collected (4 million km 2 per day), and daily revisit to an area. Each travel on the same orbital plane at 630 km, and deliver images in 5 meter pixel size.
Satellite images show flames wreaking havoc on houses, businesses, and other structures. At least 10 people have died, and the fires have destroyed about 10,000 structures. Widespread fires have ...
The nanometre (SI symbol: nm) is a unit of length in the metric system equal to 10 −9 metres ( 1 / 1 000 000 000 m = 0. 000 000 001 m). To help compare different orders of magnitude , this section lists lengths between 10 −9 and 10 −8 m (1 nm and 10 nm).
Images. Image search results are images sorted by relevance, with images of the highest relevance appearing first. A number of factors are considered when determining whether an image is relevant to your search request. Because these methods are not entirely foolproof, it's possible some inappropriate pictures may be included among the images ...
