The AOI should be defined by WGS-84 latitude/ longitude or UTM coordinates for the top left and bottom right corners of your AOI.
Another source of imagery is ImageSat International, which operates EROS-B, a satellite with 0.70 meter panchromatic resolution. This can be done by zooming into the appropriate area and either taking a screenshot or using the Export Map feature to create a scaled down image TIFF or JPEG file in ArcMap, or using the Print Composer in Quantum GIS. In other words, a house in one image should be in the same location as that house in another image.

Researchers will then need to work through the process of identifying areas of interest, searching for and locating relevant satellite imagery, and acquiring and analyzing that imagery.
While this does not produce the same image that a 0.5 meter multispectral sensor would have, it does approximate one. The image on the right is color-infrared, and displays the near-infrared, red and green bands.
Areas of interest can be defined in ImageFinder by entering coordinates, uploading a shapefile, or drawing an area of interest, as outlined below. Then, make sure the status bar, displaying latitude, longitude, and elevation, appears along the bottom edge of the map window. Although the type of stretch will vary according to image, typically a standard deviation stretch or maximum-minimum stretch will produce the most ideal results.
A shapefile of the area of interest will also be needed. Please note that for GeoEye images, a minimum area of 49 square kilometers must be ordered.

This level of resolution is ideal for analyzing conflict areas, where small houses and other structures are often destroyed by violence. During the second round, refine those areas by marking only those where the most obvious change has occurred, taking care to account for possible seasonal variation, differences in the direction of the sun, and other environmental factors. With the shapefile created, begin the assessment at one corner of the image and scroll in one direction until the other edge of the image has been met. When using the above methods fails to locate an area, web searches often yield useful results from news articles and blog posts. Each company operates satellites with less than one meter panchromatic (black and white) resolution, with some also capable of less than two meter multispectral (color) resolution. To search the DigitalGlobe archives using the area of interest, the KML file will need to be converted to a shapefile. In addition to factors such as resolution and elevation (off-nadir) angle, there are other considerations such as sun angle, seasonality, native GSD (Ground Sampling Distance) and accuracy, etc. If the user wishes to edit the polygon, simply right-click and select Properties to make changes.

Note that many satellite images are comprised of multiple bands, which indicate reflected wavelengths of light captured by the satellite sensor. This can be remedied through "pan-sharpening," by which the color information of a multispectral image is applied to the black and white image of the same area. We accept credit card payments from American Express, VISA, MasterCard and Discover as well as wire transfers. Google Earth (GE) is a free, stand-alone desktop application that provides satellite imagery of much of the world and is useful for identifying an area of interest. To do so, select View < Layout View. Because whole images are generally too large to disseminate easily, use small snapshots of the damaged areas for the report. When an image has been found, a snapshot can be saved by going to File < Save < Save Image. In order to provide you with the best solution for your specific requirements, all projects are custom quoted. Various options exist for viewing imagery, from GIS programs like ESRI ArcMap and the free Quantum GIS, to software designed for imagery analysis such as ERDAS Imagine, Opticks and MultiSpec. The images may not share the same resolution, color, or clarity.
