Introduction: Growing blueberries is one of Maine's largest economic exports. Blueberries are native to Maine and have adapted to acidic soils with low fertility capacity. The purpose of this investigation is to examine changes in land use that may have occurred over time and the impact of blueberry cultivation on Maine lands. Have the arid areas in which blueberry cultivation is practiced increased? Has this increase possibly affected land use for other amenities such as waterways? To help us we will use the remote sensing tool which is Landsat Imagery and work with it in a GIS station. Landsat 5 is a low-Earth observation satellite whose mission is to collect raw images from the Earth's surface. It began its mission in 1984 and was used to collect over 2.5 million images in a 705 km orbit. it had a transmission bandwidth of 85 Mbit/s. it takes 16 days to complete its orbit. It has seven spectral bands with a thematic mapper and multispectral scanner functionality. For this exercise we imported 1999 and 2010 Landsat images into an ArcGIS workstation. We then modified some elements of the images to allow us to understand the changes in the land surface at the location, the changes in the barren blue berry between 1999 and 2010. Methodology: to help us in the land survey investigation; I took the available data from Land Sat 5 imagery and imported it into the GIS workstation; the data went back to 1999 and then a second to 2010. The next step was to normalize the images to allow us to make comparisons; this involves converting the digital numerical values present in each pixel and converting them into radiance and then back into reflectance. In the conversion from digital number to radiance I used the map algebra function of ArcGIS...... middle of the paper ...... analysis and so I removed the cloud cover, added the reflectance stack and did a series of model builders to aid analysis. The calculations to find the statistical changes in the mean arid zone were performed using the geometric tools. Conclusion The arid zone, which is the most fertile area for blueberry cultivation, grew throughout the study site between the years 1999 to 2010. I used the data collected by land sat 5 and imported it into an environment Arc Gis. Following the procedures carefully, I analyzed the different scenes from 1999 and then 2010; these were significant changes in land cover and this was observed after data cleaning. Blueberry cultivation represents a huge investment in the state of Maine, but it is also important to respect land use to avoid damage from environmental impacts on other areas such as rivers, streams and land set aside for other purposes.
