With an excellent understanding of the technical capabilities of all the commercial imaging satellites, we can select the appropriate sensor, perform archive searches and ordering, and custom-process the imagery to meet your needs, Land Survey is a reseller of satellite imagery and products. Representing partnerships with GeoEye, Digital Globe, and SPOT
Land Survey has developed sophisticated image classification techniques to fully exploit the value inherent in new data sources that offer improved spatial and spectral content. For example, Land Survey’s UltraCam large-format digital camera collects data in red, green,FIFA 15 Crédits blue and near-infrared channels, 12 bits-per-channel, at more than one frame-per-second. This data is cost effective and offers practical technical options for urban and natural resource professionals alike. Land Survey is an industry leader in the use of this data for addressing land management problems in all disciplines.
Your land management needs will determine the level of detail and accuracy of the proper classification scheme for your project. Four levels of the standard land cover product are available—Impervious and Levels 1–3—but custom classifications are also available. Land Survey will work with you to determine the classification system that is best for your application.
If your needs are not met by the standard products there are a number of options such as:
- Custom classification schemes
- Quantitative accuracy assessment
- Subscription services for regular imagery updates
- Serving imagery and classification through web site
In many countries, the mapping that is available is either obsolete or at inappropriate scales for development. This poses a problem for organizations that require up to date information prior to the commencement of activities in the field.
Land survey offers a low-cost solution to the problem by developing Raster Maps of the areas of interest, using Satellite Imagery as the basis for such products.
Typically, 'true colour' maps at scale 1:25,000 may be quickly produced using Landsat 7 multi-spectral and IRS-1C 5.8 metre Pan. The ortho-rectified product is a Pan-sharpened colour image with 5 or 6 metre resolution.
Much larger scales of mapping may be produced using commercially available 1 metre imagery e.g. IKONOS as the raw data sets.
Typical successful applications of Land survey.'s Raster Mapping products include planning for 2-D and 3-D Seismic Surveys, selection of Pipeline Routes and overall planning of Field Development.
Delivery of medium to high resolution imagery in black and white or colour format. Geo or ortho-rectification using GPS control and digital terrain models. Image mosaicing and tiling to user defined formats. Production of laminated maps.
• Land Survey and MAPA distributes worldwide data from Digital Globe's QuickBird Earth-observation satellite in the United States and exclusively in Mexico.
• QuickBird was successfully launched on October 18th 2001.
• QuickBird offers the world’s highest resolution commercial earth observation satellite data available.
• Geolocate features in remote areas within 23 meters (RMSE) to create orthoimagery without the use of ground control points.
• QuickBird offers 5 spectral bands to accommodate most application needs.

o 1. In respect to the type of Energy Resources:
o A. Passive Remote Sensing: Makes use of sensors that detect the reflected or emitted electro-magnetic radiation from natural sources.
o B.Active remote Sensing: Makes use of sensors that detect reflected responses from objects that are irradiated from artificially-generated energy sources, such as radar.
o 2. In respect to Wavelength Regions: Remote Sensing is classified into three types in respect to the wavelength regions
a. Visible and Reflective Infrared Remote Sensing.
b. Thermal Infrared Remote Sensing.
Microwave Remote Sensing.
This technique may be the most effective way to collect the information. Aerial photographs and imagery carry huge amounts of analogue data. When interpreted, they can provide valuable information. This technique is helpful for environmental data, plan more detailed field investigations, discover certain classes of properties, map sites, locate and confirm the presence of predicted sites.
