6-inch resolution aerial imagery from Emerge

EarthWhere™ combined and then clipped the 4 individual images from Emerge to create one new image (mosaic). It also preserved the 6-inch resolution and radiometry from the 4 source images.

0.61-meter resolution Quickbird imagery from DigitalGlobe

This full resolution clip is from one QuickBird scene over San Diego. DigitalGlobe's QuickBird satellite has the industry leading capability to provide imagery at 61-centimeter panchromatic and 2.44-meter multispectral resolutions.

EarthWhere™ created this mosaic from 4 DOQQ (Digital Ortho Quarter Quads) from the USGS. We used a special “DOQ Matching” feature to produce a more consistent tonal balance within the final image. The DOQs were also combined using a linear-feathering technique that removes the hard edges where the images join.

We created this image using the "A over B" combiner method with the highest-resolution imagery (the 6-inch aerial) on top, followed by the Quickbird satellite imagery, and then the DRG Map on the bottom. EarthWhere™ automatically aligns the imagery with the map.

We also created this image using the "A over B" combiner method, placing the 1-meter aerial imagery on the top of the map.

The image at the top of this multiple-source composite is a Landsat 7, 30-meter image sharpened to 5 meters by ImageLinks, using IRS 5-meter imagery. The imagery in the bottom center is a full IKONOS 1-meter scene. EarthWhere™ combined both of the satellite images with a USGS 1:250,000 foot scale map using its "A over B" combiner method.

35-meter resolution satellite image from USGS Landsat 7 ETM+

This true-color (Red, Green, Blue) band combination creates a natural looking image. The visible bands (3,2,1) penetrate shallow water and detail water turbidity, currents, bathymetry, and sediment plumes. In general, dark blues in the ocean indicate deeper water while light blues mean shallower water. Healthy vegetation appears in shades of green, and soils appear as browns and tans.

This image combines near-infrared Band 4 with visible Bands 3 and 2. Using Band 4 results in more defined water boundaries than the Natural Color 3,2,1 image above. Band 4 senses peak chlorophyll reflectance as various tones of red, which enables information about the conditions and variety of vegetation to be analyzed. Generally, deeper reds indicate broad leaf and/or healthy vegetation while lighter reds signify grassland and/or sparsely vegetated areas.

This combination of near-infrared Band 4, mid-infrared Band 5 and visible Band 3 provides better definition of land-water boundaries and highlights subtle details not readily apparent in the visible bands alone. Inland lakes and streams can be located with greater precision when more infrared bands are used. With this band combination, vegetation type and conditions show as variations in hue (browns, greens, and oranges) as well as tone. The 4,5, 3 band combination demonstrates moisture differences and is useful for analysis of soil and vegetation conditions. Generally, the wetter the soil, the darker it appears. Urban areas appear in varying shades of magenta.

This 1:24,000 scale DRG Topographical Map was cut from the same area of interest as the Aerial Image above. Deselecting the mosaic option caused EarthWhere™ to output both the image and the map simultaneously.

Changing the combiner method to "Map/Image" caused EarthWhere™ to produce a new file consisting of both the image and the map. The user can adjust the percentage of map and image they want to see in their output. For this example, the map was set to 25% and the image was set to 75%.

90-meter DTED from NIMA

EarthWhere™ created this image using 35 DTED (Digital Terrain Elevation Data) files. The difference in the grayscale color represents elevation, darker color indicates lower elevation while lighter color indicates higher elevation.

90-meter DTED from NIMA

EarthWhere™ created this image using 35 DTED files. Color for a specific elevation is applied using a predetermined color table. For this example, dark green indicates between 3,000 to 3,500 feet, while white indicates over 12,000 feet.

EarthWhere™ created this image using 35 DTED files. The "Shaded Relief" option was used to introduce a light source that produces shadows.

EarthWhere™ created this image using 35 DTED files. This example used both the color table corresponding to specific elevation and the "Shaded Relief" option to produce a colorized, shaded relief image.
