Data and project conversions Lecture 10 November 16, 2006
Conversion • Data conversion is from one data type or format to another • Project (or coordinate) conversion is from one projection (or coordinate) to another
Conversion tools • From raster • To CAD • To coverage • To dBASE • To Geodatabase • To raster • To shapefile
Coverage conversion • From coverage • To coverage
Projections and transformations • Define projection (or coordinate system) • Feature • Raster
A demo • A text (or dbf) file • Convert to shapefile or feature class • Define projection (coordinate) • Reproject to USA Contiguous Albers Equal Area Conic • Interpret to two raster file • DEM • Ozone concentration • Overlay the Ozone with city or population map to see any relate between ozone and population • ……
