To transform Coordinates in a SHP file - use Project Tool in ESRI ArcView


I was having a great deal of trouble with projected coordinate systems. Our workplaces uses data that is created using a stateplane projection, but the google maps API wants data in the form of WGS1983 format. For the longest time I didn’t know how to get over this hurdle. I could convert the shapefiles using shp2mysql.exe but shp2mysql wouldn’t change the projection and the polygons wouldn’t work.



The answer was simple: a tool in ESRI’s ArcView called Project (management). I searched all over looking for transform or coordinates or something similar: but Project is the tool you’d like to use: it allows you transform any source data into another coordinate system or projection including datum and spheroids.

And now the data can fly back and forth every whichway.
