Multispectral Imaging
There is a wide range of satellites providing multiple spatial and spectral resolutions on the market from 5 meter panchromatic (greyscale) to 30 meter data with 6 spectral bands of information. The most widely used multispectral data comes from the Landsat Thematic Mapper (TM) satellites. Landsat TM satellites have been capturing earth imagery since the early 80's and have an extensive worldwide archive. Other multispectral imaging satellites include SPOT and IRS sensors. NASA will soon launch the Terra and EOS satellites which include the ASTER, MODIS, ALI and Hyperion sensors for earth imaging.
3Di has extensive experience with multi-spectral data. We have applied this imagery to map land cover for watershed analysis, database development, pipeline routing, environmental change detection and to mineral exploration around the world.
3Di's expertise with multispectral sensors and data ensures the best-suited sensor technology will be used to best suit your needs and budget. Our ability to integrate image data from multiple sources also makes 3Di a unique solution provider. 3Di's project experience with Multispectral Satellite Imagery includes the following:
Lower Colorado River Authority: 3Di conducted a land use/land cover classification and change detection project for the Lower Colorado River Authority (LCRA) in Texas. Landsat TM data was used to map 12 land use/land cover categories. The data will used to manage watersheds for non-point source pollution.
Bonneville Power Administration: 3Di is providing remote sensing and GIS services for a project on the Flathead River in Montana. The project is focused on mapping the river and developing fish habitat maps based on the changing flow in the river system due to hydropower generation.
