Coordination problem....

SathapornMonjung — Fri, 21 Nov 2014 15:55:08 GMT

I have a map of my country and river basin bounndary in Shape file

When I open in ArcMap, no problem occure because boundary of basin is contained in Country boundary

But When I create climate scenarion in Climate change software by using country boundary and then save to .bmp (raster file).

However when I open .bmp Zraster file) and country boundary in Arcmap. Two maps seem to be stayed apart.

I have tried many ways to set up coordinate of 2 maps to be the same, but a problem still exists. Could anyone give me a solution?

Thank you very much

Hi Sathaporn,

It looks like you may need to georeference the BMP with the country boundary.

Thank you very much Jake. I did it.

Actually, after creating rainfall pattern in climate change software. The shapefile country boundary (provided by software) perfectly overlay with country rainfall pattern. The climate change software also has overlay command to add other shapefile to a program. However, when I add another shapfile of my country (is not provided by software itself), two shapefile always stayed apart. That's why I have to save rainfall pattern to BMP and do it in ArcMap.

What is the coordinate system of the original layer that you made your bmp from? This is the coordinate system that needs to be defined on the bmp raster. Then it should match up, then you can set the dataframe projection to whatever you need it to be and then go to data export data to save your bmp into that projection. It looks like the wrong projection has been defined on the bmp.
