How Do You Project A Shapefile In Arcgis?
A projection is a way of displaying the earth’s three dimensional surface on a two dimensional plane such as your computer screen or a piece of paper. There are various projections, all for different purposes. Some preserve accurate direction, while others preserve accurate area. Unfortunately none can preserve both perfectly. Geospatial data must be projected before they can analyzed accurately in GIS software such as ArcGIS. In order to compare two datasets, the shapefiles or raster files must be in the same projection. This article will show you step by step how to project a shapefile in ArcGIS from ArcCatalogue. Check that the geographic coordinate system is defined for the shapefile you wish to project. Locate the file in ArcCatalogue. Right click on the file then click properties. Under the “XY Coordinates” tab in the Shapefile Properties box you should find information on the projection and geographic coordinate system. If this information is not present, or is “Unknown” or unde
