PVA Pro 9000 is a software application for estimating acreage from aerial photographs or maps. It allows users to open images, set scales, define boundaries, compute areas, edit boundaries, and save images with polygons. The program utilizes boundary points and scale factors to calculate acreage estimates. Users can save images, scales, and polygons for editing and future use. The tool supports opening images only or complete sessions.

Notes for Project 6 PVA Pro 9000
Problem Definition The PVA Pro 9000 is a software application to support the estimation of acreage from aerial photographs or maps of geographical regions. The program provides the following functions: Open an aerial photo or map image. Set the scale of the image (e.g. pixels per unit distance). Permit the user to define a boundary around a region (e.g. a field). Compute the area contained in the defined boundary. Select a boundary for edit or deletion. Save the Image and the associated boundaries.

program uses boundary points and scale factor to compute an estimate of the acreage of the enclosed area.
Image, scale, and polygons will be saved so that they can be opened as a unit and edited. Include options for opening image only or complete session
