The software is built based on VB.Net and ArcGIS Engine.

Study area: 74 streets, 1143 alleys, and 32683 land parcels. Time spent: 11 minutes Accuracy: Calculation results are consistent and free of errors Flexibility: Adaptable to changes in state regulations by allowing changes of parameters

To implement the land pricing task:Spatial relations between street, alley and parcel can be determined accurately and quickly by using appropriate sequence of GIS spatial functions like intersection, buffer, distance measures Integration of these spatial functions into a software developed on ArcGIS Engine and programming language VB.NET The application software tested on a studied area strongly demonstrates efficient execution time and accurate performance
